Hi could you help please, I have mp4 files some of which do not fully load into PE18 (Premier Elements 18), only the sound track loads, these files do play using the Windows default program, other files recorded at the same time and from the same folder work perfectly in PE18.

 

File size, around 3 GB.

Camera used, Drift Ghost S.

PC operating system, Windows 10.

Adobe program, Premier Elements 18.

Thanks, John

    I don't know what a "Drift Ghost" is.  What are the file formats?

    The Drift Ghost appears to be an action cam. But it shoots in several formats, resolutions and frame rates, so John is going to have to get more specific about his particular clip. For instance, 848x480p is definitely not supported by Premiere Elements -- and neither is a 240fps frame rate. And is he shooting NTSC or PAL?

    Also, by Premiere Elements 18, I assume John means Premiere Elements 2018 (which is technically version 16).

      Hi Bill thanks for your advice, I've sort of had some success, I opened the troublesome clip in, sorry, Windows Move Maker, and saved the move as 1080pt, is that called rendering? The clip then loaded ok in PE (Premier Elements), I'm no expert but I expect the file size, frame rate of similar have been reduced, I know it's a bit of a bodge but it allows me to go on and have fun editing the entire film, if you have any views on how or why the temp fix worked I would be interested to hear them please, thanks again, John 


      "...is that called rendering?"  Yes, but the word get multiple meanings.   In Premiere Elements there is output rendering, preview rendering and maybe more!  The words "rendering", "transcoding" and "processing" get mixed up and interchanged a lot.

      Running the clip through Windows Movie Maker could be changing it to a fixed frame rate.  Or, maybe something else is getting changed. 

      Again, I don't know your camera.  I don't think it would be the choice between 50 and 30.  Instead, it may be that the camera is made to have a variable frame rate so that it can write to the memory card faster.   If the camera's firmware uses variable frame rates, it would be "about" 50 or "about" 30.   As an action camera, I suspect the 50 setting will get better clips when you are shooting action.  If the subject isn't moving much 30 fps may appear about the same.   

      The way to shed light on my guesses is to use the (free) program mediainfo to examine the details of the file.
