    Thought I'd follow up on this. It turns out that Youtube's own down conversion breaks the audio sync, but only at 480p resolution. Not at issue at all caused by Voukoder. Thanks for being responsive on this question, and keep up the great work! I'm rendering 8 hour long 1440x1080 h264 20Mbit bitrate videos at about 1.5 hours each on my RTX 2080 Ti thanks to this plugin. Awesome.

    Hi all,

    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.
    • CABAC
    • 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!
