The problem is jerky playback of rendered videos of duration more than about 2 minutes. This is no doubt related to other threads, but here are the specifics. Help much appreciated.
I am shooting on a SONY XR500 in 1920-1080 format, and using Vegas Platinum 10, build 179.
Match media settings gives HD 1080-50i (1920x1080; 25,000 fps).
Field order: Upper field first.
Pixel aspect ratio: 1 square
Framerate; 25.000
Rendering quality: Best
Deinterlace method: Blend
I am rendering an m2ts file
I have checked the boxes (stretch video to output frame – don’t letterbox) and save project markers in video.
Rendering itself works perfectly. The first 2 minutes of playback are completely smooth After about 2 minutes, jerky playback of the m2ts files is seen in windows media player and after uploading the m2ts file to youtube.
Here is what I’ve tried:
1. Rendering those later segments as a loop generates a smooth video. The problem is time dependent. Removing overlays and video effects doesn’t help.
2. Changing the bitrate from 16000 to 4000 results in a smooth video, but of horrendous quality. I can’t go in that direction.
3. No help from all permutations of progressive scan/upperfield/ no deinterlace/ blend and interpolate. I assume that for playback on computers progressive scan should be used? It didn’t help though. (I’ll use blu-ray for playback on TV/PS3).
4. I am shooting nature videos, which are quiet but can have plenty of movement (waves, fluttering leaves, flying birds). But, again, the problem only appears after 2 minutes
5. Same result with 1, 2, or 4 rendering threads. Using i7CPU, 8 Gbytes RAM, 2.8 GHz, 64 bit. Don’t think it could be a memory problem.
7. Do I need to make a custom template with higher fps. I’ve seen that discussed.
8. I bought Platinum after first using the demo version. It did it’s reinstall thing. Would it help to reinstall from scratch?
Much obliged with your help on this. It seems like a rendering problem, not a player problem, as progressive scan doesn’t help.
