I'm trying to get to the bottom of a large audio delay problem with my uploaded youtube videos. The rendered mp4 videos do not have this delay, but there is a significant (1 second or so) delay when playing back via the youtube player.
I thought I would start by following the exact h264 settings recommended by Google for youtube videos. I found them here:
- Progressive scan (no interlacing)
- High Profile
- 2 consecutive B frames
- Closed GOP. GOP of half the frame rate.
- Variable bitrate. No bitrate limit required, though we offer recommended bit rates below for reference
- Chroma subsampling: 4:2:0
There does not appear to be a way to affect several of these in the Voukoder interface. What are the recommended settings within Voukoder for optimal performance on youtube?
My videos are 1440x1080 30fps, and are 8 hours long.
Any help would be greatly appreciated. Great plugin!
