How to produce video for YouTube without motion problems
Using Vegas Pro 10, I have a problem with motion blurring and motion jitters on videos that have significant motion. I can render an interlaced m2s file using MainConcept MPEG2 preset with NO motion problem when played by PowerDVD or WMP. If I upload to YouTube, I get severe motion degradation when played back in HD on YouTube.
Okay, I understand that for YouTube, the video to be uploaded should be deinterlaced and preferably in a MP4 container. I have tried that and still have the motion degradation.
Let’s start at the beginning. My source video from a Canon HV30 is 1440×1080, 29.97, Upper field first, Pixel aspect ratio=1.333. I set the Vegas project properties to correspond with the source video. I set the rendering quality to best and deinterlacing to “Interpolated fields”. For rendering, I chose the Sony AVC Internet 1920×1080-30p template. The resulting video shows severe motion degradation when played locally by Windows Media Player and the same problem on YouTube.
Over the past several days, I have tried dozens of combinations of codecs, project properties and rendering parameters. I cannot seem to find the appropriate settings to eliminate the severe motion problem for HD on YouTube. I have researched this on various forums to no avail. I even tried the “VideoforYouTube” extension suggested by Steve Rhoden with no improvement.
I would appreciate any help I can get. Thanks.

Example? We can’t comment if we can’t see the problem.

The problem can be seen at https://youtu.be/UIQpw4Tc8yM. It is most evident when viewing in HD full screen.
Thanks, Bob

That sure looks like a rolling shutter artifact, but you would be seeing it in your encoded file before uploading to YouTube.
YouTube re-encodes everything. Try uploading to Vimeo to compare. You could also upload to the Cow.

I am uploading the YouTube Test 19 file to Cow.
More information! The YouTube Test 19 MP4 was rendered in Vegas 10 using the Sony AVC Internet 1920×1080-30p preset unchanged. The resulting video shows severe motion problem when played here on Windows Media Player and when played on YouTube.
When the exact same project(with Interpolation deinterlacing in both cases) is rendered using Sony AVC Internet 1920×1080-30p preset WITH THE FIELD ORDER CHANGED TO “Upper Field First”, then the resulting video plays here on WMP without any motion problem. But when uploaded to YouTube we still have the same severe motion degradation.
Does this help to understand the problem?

I have an HV30 and used to shoot a lot of video on it, and I never had this problem when uploading to Youtube. What’s your bit rate that you’re rendering to? Try adjusting that, but as Stephen said, that’s a rolling shutter artifact. So I don’t know how it wouldn’t show up in other renders.

I used the default bit rate for Sony AVC Internet 1920×1080-30p which is 16,000,000 bps. What other bit rate do you suggest?
Is there an explanation why this motion problem occurs when video is rendered progressive and DOES NOT occur when video is rendered with “Upper field first”? I have uploaded to Cow the video “YouTube Test 22.mp4” rendered with “Upper field first”. If you play the two videos full screen with Windows Media Player, you should see the difference. How would this be related to rolling shutter?

I would just test render problem sections with lower bit rates. Try 10 mbs or 8 mbs. But I’m not sure what’s ultimately causing your problem. I’ve never had this issue with an HV30. Also, try reducing the resolution to 1440×1080, since that’s what you’re shooting.
