    Hey all!

    Looking to see if I can get some help with an odd issue I've encountered. I've tried searching the forums and various guides but haven't been able to find a solution as of yet.

    I've got two videos that are near identical as far as codec information is concerned, same bitrate, similar file size, same format, etc., however one of them works perfectly fine while the other stutters and has so many dropped frames it's completely unusable.

    I've checked and they both work fine when played locally on my server pc, (using VLC), yet when playing through Jellyfin (whether using the browser client on the same machine, or a TV on my local network) it presents this issue. Both files are direct playing.

    Server: 10.10.6 (had the same issue on 10.10.3)
    OS: Windows 10, Version 10.0.19045 Build 19045

    The following are the playback details, as obtained when playing on my server PC (through web browser client):

    Video 1 (file with issue):
    Playback Info
    Player: Html Video Player
    Play method: Direct playing
    Protocol: http
    Stream type: Video

    Video Info
    Player dimensions: 1920x839
    Video resolution: 1920x960
    Dropped frames: 94
    Corrupted frames: 0
    Original Media Info
    Container: mp4
    Size: 1.5 GiB
    Bitrate: 2.2 Mbps
    Video codec: HEVC Main 10
    Video bitrate: 2.0 Mbps
    Video range type: SDR
    Audio codec: AAC LC
    Audio bitrate: 224 kbps
    Audio channels: 6
    Audio sample rate: 48000 Hz


    Video 2 (file that plays fine):
    Playback Info
    Player: Html Video Player
    Play method: Direct playing
    Protocol: http
    Stream type: Video

    Video Info
    Player dimensions: 1920x839
    Video resolution: 1920x960
    Dropped frames: 0
    Corrupted frames: 0
    Original Media Info
    Container: mp4
    Size: 1.4 GiB
    Bitrate: 2.2 Mbps
    Video codec: HEVC Main 10
    Video bitrate: 2.0 Mbps
    Video range type: SDR
    Audio codec: AAC LC
    Audio bitrate: 224 kbps
    Audio channels: 6
    Audio sample rate: 48000 Hz

    I've tried forcing transcoding, and when I manually lower the bitrate below 2.0 Mbps it's noticeably smoother/doesn't have the dropped frames....but the quality is also horrible.

    Hoping this is a one-off issue (so far haven't seen it with other files/videos) but I'm just very confused and would love to find the solution.

    Thanks in advance for any insight!
