    I have a Premiere sequence. 1280x720, 29.97fps.

    I output it as an ac3 file for audio, and an AVI file for video. The AVI plays fine.

    I brought it into MeGUI and created a .264 file. It plays back in slow motion when using PowerDVD.

    I muxed it with the audio in MKVToolnixGUI. It plays back at fast speed, and the video runs out long before the audio does.

    I muxed it again with MKVToolnixGUI, this time manually setting the frame rate. This plays back fine on my PC but when I load it onto my Emby server and play it back on my LG TV, the playback speed is all over the place. Audio is fine, but the video just randomly speeds up and slows down.

    AVI file:

    It seems you (MeGUI) set --pulldown double when encoding using x264. Don't do that if you target mkv to avoid such troubles.

    WTF? It's set to "none" in the MeGUI config and isn't mentioned in the command line thing at the bottom of that window either.

  4. My guess is you selected "Target Playback Device:" "Blu-Ray" and MeGUI auto-inserts --pulldown double because 720p29.97 is not Blu-Ray compatible while 720p59.94 is. MeGUI's log should show the actual full command-line used.

    tl;dr: Don't select Blu-Ray as target device if you are creating mkvs.
