Choppy video on YouTube

[George Dalton]

It worked well for me, it might be your connection? It wasn’t choppy at all.

I see what you mean. Give us all the details, framerate, codec, size, camera, original footage stuff.

The original video is 1440×1080 interlaced (upper field first). There are a handful of scenes shot with a Sony HD camera, but the video is comprised mostly of stills (to be technical, it’s comprised mostly of Photoshop files). These files are pretty large (generally about 5184×3456), BUT I have tried reducing the size of the pictures to about twice the project size and it made no difference in the choppiness of the video.

When Vegas prepared the video for the internet, it changed the aspect ration to 1920×1080 with a pixel size of 1.0 (I believe this is what YouTube prefers). It also deinterlaced it.

I have tried many solutions. Like I said, I’ve tried reducing the size of the pictures. I’ve tried rendering the video for YouTube using the MainConcept AVC – Internet 1080p template. I’ve tried rendering the video with a greatly reduced bit rate (CBR of 4,000,000). None of these things made a difference.

However, after watching other HD videos on YouTube, I noticed something. Whenever the camera pans in any of the videos I watched, there is the same stuttering that I see in my video. Obviously, this is a common problem. So my question is, can anything be done about it, or is that just a quirk of YouTube? Has anyone else in this forum noticed that pans get jittery when uploaded to YouTube?

I give my web guy videos for YouTube that were done using the Sony AVC Internet 1280×720-30p preset and they look fine to me.
Source video was 1440x1080i.

I have noticed some issues on Youtube with what looks like dropped frames. Sometimes it happens and sometimes it doesn’t. I’m sure bandwidth can become an issue. I see what you mean about pans.
That looks like dropped frames. I wish I had a solution for you. Seems like you have tried everything. You have probably already looked at this: https://support.google.com/youtube/bin/answer.py?hl=en&answer=74662
