Short Reels

Though short reels extension says MP4, it is impossible to have short reel video as project file in APPr. Only it’s audio file gets upload. What is reason for that?

    @MahaMN Its not the extension (container) that matters its the codec used inside the file.

    Most likely its AV1 which is not supported by Premiere.

    Most likely the codec such as AV1 inside the mp4 is not supported by Premiere e.g. dowlloads from Youtube, FB……..

    1st you post what is inside the file that doesn’t work

    2nd you may want to use https://handbrake.fr/ open source transcoder/converter to convert to a codec that may be edited

    MP4 is a wrapper, what is inside YOUR wrapper - Exactly what is INSIDE the video you are editing?
    Report back with the codec details of your file, use the program below
    Free program to get file information for PC/Mac http://mediaarea.net/en/MediaInfo/Download

    - a MediaInfo tutorial https://youtu.be/Ivy9ckSX1M0

    - when you analyze your file in MediaInfo and post a screen shot in the forum, do so in TREE view
    - post your information IN your message, not as an attachment that someone would have to download
