Most MP4 files not importing correctly in Hitfilm Express--they just show as exclamation marks

When I drag a batch of 8 mp4 files to Hitfilm only two show up and the rest show as Exclamation marks.  The same files import OK in other Video editors.  In one case it did not import and did import when I changed the frame rate to a lower one.   This is weird.  It should just work!

    Above should read " In one case it did import and did import when I changed the frame rate to a lower one.

    MP4 is simply a container, and is no guarantee of compatibility with HitFilm. Not all video editors support the same format and codec combinations, so you can't expect HitFilm to "just work" with whatever happens to work elsewhere.

    Re: the files that don't import cleanly, what codec do these files use? What hardware/software created them? An easy way to answer lots of questions is to provide a MediaInfo text report from one of the problem files.

    Ah. These are NOT "Mp4" files.

    These are "MPEG-2" Files. MPEG-2 is a licensed format, and you will require the "Formats: Starter Pack" add-on if you wish to directly use these files in Hitfilm. We'll discuss other options later in this post.

    https://fxhome.com/store/hitfilm-express#formats-starter

    Relevant section of your MediaInfo report.

    Format                                   : MPEG-PS

    Format                                   : MPEG Video
    Format version                           : Version 2

    "Mpeg-PS" is "MPEG-Program Stream" which refers to the video portion of MPEG-2.

    And, of course the "Format Version" is "Version 2."

    MP4 files will come up in MediaInfo as "H.264" or "AVC"

    Out of curiosity, what program are you using to rip from YouTube/Netflix? The MPEG-2 encode is a little unusual, and the frame dimensions are 1032x946, which is just $&@#ing STRANGE!

    640x360, 1280x720, 1920x1080, 2560x1440 and 3840x2160 would cover most current frame sizes, so those dimensions are extremely non-standard.

    Anyways, other than the Formats: Starter Pack, you other option is to bounce the file through another transcode to convert to actual mp4. This video, starting around 19:30, covers some free options to do so. (Ignore the GoPro bit, which is now obsolete/incorrect) The video description links to other forum threads wit further information.
