Voukoder export fails when using In/Out points in Media Encoder

1. offizieller Beitrag

    When exporting with Voukoder in Media Encoder (using any codec), if In/Out points are set, the exported video may have playback problems — such as only audio playing, or the file failing to open at all.

    If I export without setting In/Out points, or use the native Adobe encoder, everything works normally.

    Example:
    If I export a 10-minute segment from a longer Premiere Pro sequence, and the In point is not at the start of the sequence, the resulting video has incorrect timing and cannot play correctly.

    • Voukoder Pro version: [2.0.12.0]
    • FFmpeg version installed: [7.1]
    • I’m using Adobe Media Encoder 2025 (v25.3) with Premiere Pro 2025.


      I inspected the exported MP4 using FFmpeg and found that the video and audio streams start at different timestamps, which likely causes the playback issues:
    • Audio stream start time: 0.000s
    • Video stream start time: 2047.345s
    • Actual video duration: ~99s
    • Container (MP4) reports total duration: ~2147s
    • This means the video stream starts much later than the audio stream. Some players (like PotPlayer) are able to compensate, but most players (like VLC or Chrome) fail to play it correctly — either showing a black screen or refusing to open the file.

    I have the same issue using the following setup:

    In Premiere Pro, I’m exporting a short segment using Source In/Out points instead of the entire sequence, but the output file has mismatched video and audio tracks and incorrect duration as seen in the metadata below. Here are the specific issues:

    • Wrong overall duration: The file’s duration is 4 min 47 s (the full sequence length), but it should match the selected segment length (24 s 619 ms).
    • Video starts at the sequence beginning, not at Source In: The output starts from frame zero of the sequence, so there’s black video from the sequence start until the Source In point.
    • Video ends correctly at Source Out.
    • Video track Duration is wrong, but its Source duration is correct: The video track’s Duration metadata shows 4 min 47 s (the full sequence), while its Source duration metadata correctly shows 24 s 633 ms — meaning the video stream contains the entire sequence, not just the selected portion.
    • Audio track has the correct Duration and Source duration: Both Duration and Source duration fields for the audio are correct (24 s 619 ms).
    • Audio is placed at the beginning of the output file: The audio starts at time 0 instead of being aligned with the Source In point, so it’s completely out of sync with the intended video segment.

    I've also attached my scene.
