    I’m running 13.1.5 on an iMac Pro 15.4.6. I have a bunch of .mp4’s captured and exported from Snagit that have non-standard dimensions as they are screen captures, like 1080 x 1348. Encoding is mpeg-4 base media version 2.

    The videos play just fine in preview, but when I drag them to the timeline only the audio goes, no video. I tried creating a sequence much larger than the frame size (4k) but that didn’t help. Normally premiere prompts you if the video size and timeline settings are different, but I am not getting this prompt.

    How can I edit these mp4s in Premiere?

    Those files are in a format that isn’t supported in Premiere. You’ll need to transcode them to a format that works or capture in a supported format.

    Looking at

    it shows that mpeg 4 is supported. Is there a way of finding out what will work and what will not without having to actually import the file? In this case the file is in Baseline L3.2.

    It does sound like it may be an old 32 bit version that isn’t supported any longer. But I can’t say for sure.
    Try transcoding to another file with something like Handbrake and see what happens.

    Guessing you did not source patch the track:
