How to encode 720P HD files for Youtube.

[Demistate]

Youtube supports up to 4K (4096 x 2304) playback. Users can select their desired resolution if available. Youtube just announced that you can upload up to a 15 minute clip now.

One final note: if you’re uploading a video that was previously rejected for being too long, you’ll have to go into “My Videos” and delete it before attempting to upload it again. Thanks and happy uploading!

You can see my examples here:

To send a direct link with HD enabled, add &fmt=22 added to the end of the URL for 720P and &fmt=37 for 1080P.


BEST SETTINGS TO GET YOUR VIDEO IN HD ON YOUTUBE:

• Frame size up to 4096 x 2304
• Less than 15 minutes
• h.264 video codec
• AAC Audio codec
• .mp4 container
• 2-pass encode
• HIGH PROFILE @ level 5.1
• Average bitrate as high as you can go without filesize over 2048 megabytes. I recommend a 10+ megabit per second video stream.
• Audio Bitrates at 320Kbps and higher. Surround sound is supported, but will be downsampled to stereo at this time.

You should be able to do 27 MegaBits per second, with a 320 KilloBits per second audio track and not hit the 2048 MegaByte limit for a 10 minute film. Most hollywood Blu-Ray movies are 21 MegaBits per second average, so this is very very good quality. Keep in mind that uploading 2048 MegaBytes to Youtube will take a few hours on an American cable modem service.

You can use these same deliverables for Vimeo as well (Up to 1920x1080)

OTHER FORMATS DO WORK:

If you can't export h.264 above because of your encoding software here are some alternatives.

·WMV9 2-pass at 10,000Killobits per second Average Audio at 320Killobits per second
·Quicktime MOV files (QUICKTIME IS NOT A GOOD DELIVERY MEDIUM. You will get gamma shift and your video will look ugly. You have been warned.)

STANDARD QUALITY LOOKS BAD:

Tough Luck. Youtube is a free service and they are free to encode their videos however they want. Try other video sharing services, or add &fmt=18 to the end of the URL for a higher quality, 480P version.

MY VIDEO STILL LOOKS BAD, WHAT ELSE CAN I DO?

Try hiring a professional compressionist to create high quality deliverables for Youtube. A Professional will be able to pre-process your footage so that it compresses better for video sharing sites. Final Cut Pro/Adobe Premiere Pro are not good pre-processing tools and will give you sub-standard results if you do any scaling, de-interlacing, or color space conversions.

YOU'RE WRONG ABOUT X.

I've tried to keep the information in this post as short as possible. There are some caveats to all kinds of file encoding. Let me know if you feel like I should change something.

Amazing stuff you've uncovered here Alex! Thanks for the hard work getting this to work, I'll be spreading the news.

Those videos in Youtube look great. The only problem I have with them is the file size. They take too long to view.

[kruzmode]

Also what format would you recommend filming in to produce high quality HD videos online, 720p or 1080i. Thanks

[Demistate]

Shooting 1080P is always ideal, and then downsample with a good scaler like spline36 in Avisynth down to 720P.

Shooting interlaced always causes problems when trying to convert to progressive. It will never look right. Shoot 24pa in 1080 or 720P on your HVX.

I have a Sony HDR-FX7E High Def video cam. It can shoot in 1080i/Dv only. Would I be able to scale down to 720p via compressor? A 13 sec file I just tried to compressed with a 5000kbits, created a 15mb video file. Thats a little large for embedding into a website?

You'll have to run it through a deinterlacer, which always takes away quality. I'm not familiar with how good Compressor's pre-processing capabilities are.

Deinterlace the source, and scale it down to 1280x720. You should get acceptable results.

shoot I just got Vimeo Plus... oh well, I guess I will use both sites now...

You export for Youtube HD the exact same way we have been exporting for Vimeo HD for over a year now.

Please add this to the original post:

It is VITAL that your audio's sampling rate be encoded at 48kHz, not 44.1kHz or anything else. Right now there is a glitch with YouTube HD videos which will cause your video to skip every few seconds and it ain't pretty. Stick with the standard digital video 48kHz setting and you'll be gold.
