Sound track only loading

[johnp69874918]

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?

[Steve Grisetti]

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).

Steve thank you for your help.

I think the question of frame rate and so on is probably irrelevant
as some of the film files load ok and some don’t, these files were uploaded
from the cameras SD card and were all taken consecutively and at the same
settings, the camera automatically cut a continuous film into 20 minute clips,
some load and some don’t.

You are right the Drift Ghost S is an action camera, I am
very pleased with it but I don’t tend to tinker with the settings they are as
factory default.

Thanks again for taking the time to help me, John from sunny

It still could be frame rate.  There is a program called mediainfo that will look into the file and report the details.  It can offer some clues.

If it helps, you could send a bad clip or two via dropbox or equivalent.  I could give it a try and maybe figure something out.

Good luck with this!

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

PS Bill I will also adjust the frame rate on my camera (Drift Ghost S) from 50 to 30 to see if this helps without reducing the quality of the frottage too much, I'll post to let everyone know how this worked out, John from sunny Devon UK

"...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.

PS The file format is mp4, thanks, John
