Encoding YouTube Videos at the Highest Quality

Encoding YouTube Videos at the Highest Quality

With one billion viewers every month, YouTube is a distribution channel you don't want to miss out on. From codecs to bit rates, this in-depth look at the best way to encode your videos for YouTube can help you become a YouTube encoding expert.
Your video production is finally ready for the world to see. You've spent hours fine-tuning your edits, dialing in your color grade, and mixing your sound track. When you upload your video to YouTube, you want it looking its best. But what compression settings should you use? Which file format should you export your video to, and what bit rate will give you the highest video quality while still playing back smoothly online?
To answer these questions, it helps to know how YouTube processes your video once it’s been uploaded to its video servers. When you know what's going on behind the scenes, you'll understand the best settings to use, and why you should use them.

Inside YouTube

When you upload your video to YouTube, its video servers kick into action and start transcoding your file into a set of optimized video streams. This allows your video to playback smoothly on everything from mobile phones to desktop computers. The individual video streams range in resolution and video quality from tiny postage stamp sized videos all the way up to 1080p, and even 4k.
The important thing to remember is that anything you upload to YouTube will be transcoded. So you don't want to upload a highly compressed, low bit rate video. It's just going to get compressed again. Instead, you always want to upload a high quality video to YouTube.

Codecs in Use at YouTube

So what video format does YouTube transcode your video to? Maybe you can match its settings and keep it in the same format so your video doesn’t need to be transcoded. Well, it's a good idea, but it doesn't exactly work that way. For starters, YouTube uses more than just one codec, and each codec is encoded to multiple resolutions and bit rates.
H.264 is the codec used by most of YouTube’s video streams right now, but there are also other codecs in use such as VP8. Some codecs are still in use for compatibility with older cellphones, and newer codecs are in development such as VP9, which promises to deliver even higher video quality than H.264. (See the sidebar for details.)

Video Formats Accepted by YouTube

You can upload just about any kind of video to YouTube, from the video you just shot with your mobile phone, to your latest HD video production. YouTube's list of supported video formats includes MOV, MP4, AVI, WMV and many others. You may be surprised to find out that YouTube will even accept high quality video formats like ProRes, DNxHD and uncompressed 10-bit HD video.
Now just because you can upload uncompressed HD doesn't mean you should. For one thing, it will take a lot longer to upload your file. But even if time isn't an issue, there are a few conversion details you have to watch out for. If you've got an interlaced HDV timeline, for example, you don't want to just export a movie and upload it. First you need to deinterlace the video, scale it to the right resolution, and decide how much time you want to spend uploading it.

Quality Versus Upload Time

If video quality is your number one priority, then by all means, upload ProRes, DNxHD or uncompressed HD video files. You'll get fewer video compression artifacts on YouTube when you upload high quality video formats, as opposed to low bit rate files. So if you've got the time, upload the best video you've got. At some point though, the visual difference between a ProRes file and an uncompressed file is indiscernible, the only real difference being file size. So don’t spend more time uploading than you have to.
Whatever you upload to YouTube is locked in. You can’t change out the file to increase its video quality later on, without also losing your viewer count information.
If time is of the essence, an H.264 video with the MP4 file format is the way to go. This is YouTube's recommendation. Keep in mind however, that whatever you upload to YouTube is locked in. You can't change out the file to increase its video quality later on, without also losing your viewer count information, along with any links to your movie. The best you can do is remove your video entirely and upload a new one.
If YouTube starts using a new codec like VP9, they'll transcode your video using your original upload. If you uploaded an H.264, that's as good as it's going to get. But, before you go running off to upload all of your uncompressed HD 1080p files, there are a few things you'll want to keep in mind.

File Size and Duration

You'll need to keep an eye on the file size and length of your video. With a standard account, the video you're uploading to YouTube can't be any more than 15 minutes in duration. So if your video is longer than that, you'll have to get your status verified, or split your video into shorter pieces.

Verifying your account status is fairly straightforward. You'll need to enter your mobile phone number, and as long as your account is in good standing you'll be sent an activation code that will allow you to upload longer videos. Once you've verified your account you'll need one of the very latest Web browsers if you're going to upload anything that's more than 20GB in size.

Getting the Format Right

Anytime your video doesn't match the video stream YouTube is trying to encode, YouTube will have to do a format conversion. The simplest example is resolution. YouTube starts with your HD video and then scales it down to each of the smaller resolutions it will be streaming.If your editing format is already progressive, with one of the recommended square pixel resolutions, then you can just export your timeline and start uploading your file immediately. For example if you're exporting a progressive ProRes 1080P timeline, then you're good to go. If your editing format doesn't match, for example, if your timeline is interlaced or it's using a non-square pixel aspect ratio like DV, then you'll have to do a format conversion by exporting a new video file.

Resolution and Pixel Aspect Ratio

You want all of your videos to have a square pixel aspect ratio when you're uploading them to YouTube. For SD 4:3 video, use a resolution of 640x480. For SD 16:9 widescreen video use 854x480, and for HD video use either 1280x720 or 1920x1080.

Deinterlacing

The video you upload to YouTube should be progressive. If your timeline is interlaced, be sure to deinterlace the video when exporting. For example, selecting motion compensated deinterlacing in Apple’s Compressor will result in significantly longer render times, but can produce far better results.

Bit Rate

YouTube doesn't set a bit rate limit for H.264. They recommend 8,000 Kbps for 1080P video, or 50,000 Kbps if you have a really good upload connection and don’t mind waiting. You can get fairly high quality video using H.264 at the higher bit rates, but the file size will increase and at some point you’ll do just as well to upload a ProRes video.

Codec

To reiterate, you want to use the highest quality codec you can. If your timeline is ProRes, but it's interlaced, you don't have to export an H.264. Instead, you can deinterlace to a ProRes file on export, and maintain your image quality. The only reason to export an H.264 is to make the upload and processing speeds faster. But remember, once your file is uploaded, it's locked in and you can't change it. It may be worth a few more hours of upload time if your video is going to remain online for years to come.

Tools of the Trade

Both Adobe Media Encoder and Compressor, as well as Sorenson Squeeze, Handbrake, MPEG Streamclip and ffmpeg are all capable of encoding H.264 files. Most encoding software comes with a YouTube preset that serves as a good starting point. But remember that YouTube doesn't specify an upper limit for the H.264 bit rate, so you can raise the quality in exchange for upload time.
Some of the more advanced features to look for if you're trying to get a high quality encode at a low data rate, are noise reduction, multiple passes and banding reduction. Noise reduction plays an especially large role when trying to maximize low bit rate video.

The Bottom Line

When exporting your videos for YouTube, use high quality video formats. It will take longer to upload, but your videos will continue to be at the highest possible quality for years to come. If speed is of the essence, then export an H.264 MP4 using the YouTube preset in your compression software. You now have all the tools you need to create great looking video on YouTube, use them wisely.

The Future of YouTube

Currently, YouTube's main video player is built on Adobe Flash, but the future is HTML5. There's an opt-in HTML5 website that you can check out right now, that can stream video without a plugin on supported browsers like Chrome.
There's still a lot that the Flash Player can do that HTML5 can't, especially with regard to securely streaming copy-protected video, so Flash isn’t going away any time soon. But the new VP9 codec is making significant progress and should be nearing completion soon. VP9 is targeted to be the new codec for use at YouTube, with visual quality exceeding H.264 at the same bit rate. The future is changing quickly but if you’ve uploaded high quality videos to YouTube, you’ll be ready.

10 Video Editing Habits to Give Up

10 Video Editing Habits to Give Up

It's easy to get into a routine when video editing and as a result form some habits, and not necessarily good ones. Video editing is an art form with rules, or more realistically guidelines, that help define the difference between what's good and what's bad. Even though what is considered good or bad for video editing is subjective and somewhat arbitrary, there are some basic principles that can be followed to help make a video successful. When bad habits break the rules there's trouble to be found. Here are 10 video editing habits to give up as the New Year rolls around.

1. Winging It

A lot of creative people like to wing it, take things serendipitously and let a project unfold as they work on it. This is a habit that's easy to fall into as a video editor, footage shows up and the editor sorts it out as they go. The danger lies in the fact that a project may consume more time than necessary when a video editor is winging it, and they run the risk of missing the point. Instead of shooting from the hip, be prepared and make a plan. Learning to have a few contingency plans that can apply to multiple projects will a make a video editor more productive and help them to stay on task.

2. Scaling It Up

The excitement of a new project is exhilarating and it's easy to jump right into the mayhem of video editing. This is the problematic habit of starting before the project's ready. To avoid it, know what the goal of the project is and most importantly, know the deliverables. Ask, "How is this project going to be delivered? How long should it be? At what resolution and format does it need to be?" A project that runs too long and is in the wrong format presents a world of problems that are avoidable with some simple knowledge up front.

3. Keeping in a Cluttered Workspace

It's no lie, video editing can be messy. It's also a bad habit. That doesn't mean a video editor has to like it or live there. A video editor who keeps their workspace, virtual space, and their projects well organized will be more proficient.

4. Overusing Transitions

Transitions are a fundamental element of video editing and every video editor has their favorite go to method of moving from one shot to another. It's easy to get into a groove, use editing defaults, and transition the same way between different shots. A video editor should consciously break the habit of default transitions and use what the project calls for, not what they're comfortable with.

5. Using Jump Cuts

Speaking of transitions, jump cuts still abound in the world. Sometimes a video editor gets complacent with the lack of footage that they have in their edit bay or there is the habit of being lazy, just doing enough to get the job done. Be prepared and ready, always think of interesting ways to cover jump cuts. Use b-roll or an interesting transitional device, such as a custom graphic, to avoid the jump cut.

6. Ignoring Audio

Audio is one half of video and it doesn't always get the attention it deserves. Mixing audio as a rote technical process is a bad habit that kills a lot of good videos. A good audio mix is a skillfully crafted element of video editing. A video editor should at the least make sure that there are no audio cutoffs, that audio levels remain appropriately consistent, and that any music bed used enhances the edit.

7. Underutilizing Graphics

Graphics are now an integral part of a video editor's arsenal. This adds one more hat to the video editor's ever growing list of roles, that of graphic designer. Not every video editor is a graphic designer and that's okay. The danger is that an editor picks up the habit of using the same graphics and graphic techniques over and over again. When the habitual graphic gets used one too many times or grows old, past its stylistic lifespan, the video editor walks into trouble. The best way to avoid this habit is to be a perpetual learner and always try to come up with something new and fresh.

8. Abusing Effects

Just like graphics, effects are used regularly in the edit bay. A well crafted effect adds a certain amount of flair, flourish, and polish to a production. Effects can also be habit forming and used gratuitously, becoming ineffective. Don't use effects for effects sake, use them sparingly to make a point or subtle exclamation.

9. Stealing Ideas

The great thing about the internet is that it's easy to learn just about anything, including video editing techniques. A bad side to the internet is that everybody is learning the same thing, including video editing techniques. Self-improvement is a good habit to have but straight out imitating others is not such a great habit. A video editor should be mindful of what they learn when watching tutorials. A carbon copy effect or graphic from an online tutorial can be spotted a mile away. Personal growth is accomplished by incorporating a technique learned from a tutorial and taking ownership of the finished result, while making it wholely unique.

10. Attempting to use Every Shot

A video editor's job is to edit, to reduce, repurpose, rearrange, and craft elements into a cohesive message. A bad habit that many young editors form is they like to paint the world. They want to use everything they're given. If there's a good shot, they make sure to include it in the final edit, even if it doesn't fit with the overall message or takes away from the finished piece. This is where good videos go on to become extended pieces, with montages of unnecessary footage. Break the habit of painting the world by only using what's needed, be selective and don't feel the need to use something just because it looks good.

THE MOST IMPORTANT THING TO REMEMBER AS A PHOTOGRAPHER
The moments you chose to capture actually say more about you than about your subjects. The same thing goes, probably even a little bit more, for shooting something with direction. Sure, there are guidelines to both candid shots and directed photo sessions. But ultimately, there is the you behind the camera and a projection of you on what’s in front of the lens. Once you come to understand that, or remember it after a while, because in the daily rush of having a successful career you might forget it, you will most likely have a brief moment of introspection, a sort of talk with yourself if you will. I don’t mean to get all philosophical and stuff, it’s not really my thing, but the fact is that each of us is different, and so should our photos. Listen to yourself every now and then and bring out your personality because that’s part of what will make you appreciated. Sure, the subjects you photograph have a lot to do with it, but it’s more important how you deal with them.
The same thing goes for editing and retouching. After you come back from a productive day of shooting, download everything from your memory cards and start browsing, the photos you pick out to be the best are an indication of what makes you tick. Do that with another photographer by your side, and even if you will have common selections, I guarantee he’ll be choosing a few different shots as well.
Then there is the retouching part, the final look you give to a photograph. I love it just as much as photography itself because it has brought on a whole new arsenal of tools you can use to create cool stuff, and if you learn how to use them properly, your personal style or voice, whatever you want to call it. will come out just as much as it does in the raw photograph.

Becoming a Pro Video Editor



Video editors need three things to be successful: a comfy editing suite, a strong business network and a lot of coffee. Let's break down a few important components to take a closer look at how to start a successful video editing career.
1. Preparing a Professional Editing Suite
You're going to spend a great deal of time in your editing suite, so it's important that you set this space up in a way that allows you to stay busy and focused. A spare room can make a good editing suite. Many people convert a spare bedroom in their house into a editing suite and office, complete with not only their editing equipment, but all their business equipment as well. With a very large room you can even add a viewing area, a portion of the room that a client and you can watch a production on an actual television set. A small sofa would be a nice touch.
Small spaces will work just as well and your living room can double as a viewing room if you want to take advantage of more rooms in the house.
Editing suites absolutely need air conditioning, not only for your comfort, but also to make sure your editing equipment doesn't over heat. A powerful editing computer can heat up a small room quickly to temperatures well over 90-degrees. You'll find that you're going to need to rely on the air conditioning quite often. Some editing suites have in-wall air conditioning units to help balance the load with the entire household. We can't exaggerate the importance of air conditioning. Not only does it help keep your equipment running without any issues, it will keep you fresh and working without any discomfort. For those of you who like a warmer working condition, it's time to update your fall wardrobe.
Power conditioning and grounded outlets are also critical. Preventing equipment damage, should you experience a brown out or power surge, is key. Make sure to use a surge protector and to have grounded power outlets. Also, invest in a good UPS (Universal Power Supply) that has enough outlets to power your video editing computer, at least one monitor and any external hard drives for at least a few minutes. Should your power go out while working, a UPS kicks over to the battery supply giving you a few more minutes of power to save your files and shut down your system properly. This can be a very important piece of equipment that will pay for itself even if just for that one time that power goes out. If you're editing on a laptop (which should have a battery) you won't need this unless you want to keep any external hard drives running. Many UPS systems also have power conditioning features, like surge protection.
Most editors spend a good deal of time sitting in their editing suite - as you can imagine- editing video. A good, ergonomic office chair is money well spent. Test a variety out if you can and read some reviews online. Plush chairs are not always the best. Many high quality office chairs use a mesh like material to allow heat to transfer more easily and keep your back dry. Remember, your life is going to be spent in this chair, so make it a good one.
Also spend a good amount of time researching desks, keyboards and mice (or whatever tool you'll use to control your machine). Make sure to have plenty of room on the surface of the desk to do your work. Don't forget that most professional editors have at least two monitors and in many cases three when you include a TV monitor. Logic and Bella make Pro Series keyboards that has the shortcut keys graphically laid out on the keyboard for specific video editing software and a Jog/Shuttle dial. This is great for daily editing use.
Many video editors also need a professional set of audio monitors. These can be just as expensive as a good video monitor. Audio monitoring is often overlooked in home-based editing suites. But it's critical to hear the audio accurately, just as it is to see the video you're editing, so you can make edits as needed.
A last consideration for making your video editing suite look and feel like a pro suite is to paint your walls black. Painting your walls black is a good way to make sure you see the luminosity and colors on your monitor with better precision. The lighting in the studio should also be subdued and not place any glares on the screen. Cover any windows, so that there's no light coming in. Rather than blocking them completely, you may want to use a heavy drape, so that you can pull it back when you're not working on video and provide a little variety. A matte black paint will do the job on the walls and ceiling, and adding desk lamps to light up your workspace is a good idea. As you work in this environment, make sure to give your eyes some rest and refreshment occasionally throughout the day. Your eyes can adjust to this environment, and your perception of color and luminosity can alter. Make sure to mix it up a bit.
2. Business Networking Is Key
A busy video editor spends a great deal of time locked in the editing suite. This is great for business in the short term, however it's hard to find new prospects from here. Word of mouth is a powerful marketing approach, but even the most prosperous video editors need to get out of the office and build new relationships. It's truly just as important as having the right video editing equipment.
Join a local business networking group like the Chamber of Commerce or another group where, ideally, you provide a unique skill to the group. Make yourself known and look for opportunities to provide your services to these trusted vendors in your community. Word of mouth can do a lot for your business. Also, look for video editing and creative groups to join and provide your expertise in this specific area. There are a lot of video shooters who need a good editor to bring their projects to life.
3. Coffee Is Required
Well, not really, but motivation is necessary to keep up the daily editing routine, grow the business and continue to push your art to new levels. One of the best ways to stay inspired and challenged is to find a mentor. Even editors who have been at it for awhile can benefit from a mentorship with a video editor or producer. Since the democratization of video production in the mid '90s, there has been a huge influx of video editors in the marketplace, but only a few have proven to be successful. Try to find someone, not just a video editor, but a director or producer, who can help provide you with honest critique and insights into the industry. A good mentor will help you grow, not only as an editor, but as a business. Many mentors may even throw you a few jobs that may be unattractive to them or when they're too busy.
Inspiration can be found anywhere, but it's easier to find it if you've got access to content. I can't recommend any higher Netflix for the job. A good diet of DVDs can lead to new ideas and a better understanding of the art of video editing. Don't over do it though. If you're watching Dumb and Dumber for the one hundredth time you better have completed all your clients' work for the week.
With the proper editing suite and good business opportunities you may find yourself one day mentoring and lecturing yourself. Best of luck!

"A teacher asked seven-year-old Kazim, "If I give you one apple and one apple and one apple, how many apples will you have?" Within a few seconds Kazim replied confidently, "Four!"

The dismayed teacher was expecting an effortless correct answer (three). She was disappointed. "Maybe the child did not listen properly," she thought. She repeated, "Kazim..., listen carefully. If I give you one apple and one apple and one apple, how many apples will you have?"

Kazim had seen the disappointment on his teacher's face. He calculated again on his fingers. But within him he was also searching for the answer that will make the teacher happy. His search for the answer was not for the correct one, but the one that will make his teacher happy. This time hesitatingly he replied, "Four..."

The disappointment stayed on the teacher's face. She remembered that Kazim liked strawberries. She thought maybe he doesn't like apples and that is making him loose focus. This time with an exaggerated excitement and twinkling in her eyes she asked, "If I give you one strawberry and one strawberry and one strawberry, then how many you will have?"

Seeing the teacher happy, young Kazim calculated on his fingers again. There was no pressure on him, but a little on the teacher. She wanted her new approach to succeed. With a hesitating smile young Kazim enquired, "Three?"

The teacher now had a victorious smile. Her approach had succeeded. She wanted to congratulate herself. But one last thing remained. Once again she asked him, "Now if I give you one apple and one apple and one more apple how many will you have?"

Promptly Kazim answered, "Four!"

The teacher was aghast. "How Kazim, how?" she demanded in a little stern and irritated voice.

In a voice that was low and hesitating young Kazim replied, "Because I already have one apple in my bag."

Moral of the Story: "When someone gives you an answer that is different from what you expect don't think they are wrong. There maybe an angle that you have not understood at all. You will have to listen and understand, but never listen with a pre-determined notion." -
