MP4 Video Imports Audio Only

Hey chriswyatt25, ​I had the exact same issue, none of the above helped me (working on a Mac). My scenario was importing vimeo and youtube files for a client's newest promo vid. All of them worked but one, i've never had this issue before and i've been doing it for years. For some reason this file only shows Audio in the project, same as you, (not the timeline the source window and bin itself). Tried some of the relevant solutions above and none worked and could not see any difference between this particular file and any of the others. But it was a really simple fix for me, just ran it through a third party convertor (iSkysoft Media Convertor Deluxe), made the output settings HD 1080P (same as it was in the first place) and then dragged and dropped it in directly from the folder on the hard drive straight into the bin folder in the premiere project and; boom. Done. Both Audio and Video. Didn't need media browser or ingesting or anything like that, must've just been a screwy file, alignment of the planets or a glitch in the Matrix. If that doesn't work for you keep asking in here. Let us know when it's solved.

Cheers,

Sai

FYI, for anyone interested in finding a resolution to this problem .

After doing considerable experimentation I've discovered what the problem is and why Adobe (and MOVAVI converter Premium) will "sometimes" Import a 4K MP4 video/audio file as Audio Only.

The issue  appears to be that Adobe is looking at the "end of the file" to determine how to import the file.  In my case the recording capture tool I use is Magewell 4k dedicated capture PCIe card.  What appears to be happening is that when I hit the "Stop" button for the Magewell Capture Express software and there is additional audio being mixed in with the recording their will be a very short (as in < 1/10th of second) audio only segment at the end of the video file.

This audio with no matching video segment seems to make Adobe PP think it's an audio ONLY file.  It seems to be making an assumption there will always be a video segment for every audio segment.

How I confirmed this issue is by pausing the source video/audio BEFORE I stopped my capture device (Magewell) from recording.  This solved the import problem in every test case I ran against it.  This also re-enforces the solution I had to one of these files that caused Adobe to CTD, that solution required that I trim the end of the video just a few frames to prevent the CTD on Export.  Again, it was "end of the source video/audio".

So, just in case anyone from Adobe is paying attention (BTW, Adobe NEVER got back to me via their feedback, not really surprised), I would recommend you (Adobe software engineers) improve your Import code to evaluation more than just one or two last segments of the file to determine "type" of content.  This will make the Import process considerably more reliable.

Ok, I solved it. I'm a newbie so I'm sure there's another way that I haven't thought about. But after trying all the tips from the helpful people here I was still getting nowhere. Here's what I did:

I right-clicked the MP4 file to view the properties. Under details, I chose Remove properties and personal information. Then I chose to make a copy of the file. And the copy imports nicely to Premiere Pro.

By the way, the video in question is a screen recording by the Windows 10 screen recorder. All the videos recorded in the last couple of months imported as they should, they still do, but the latest ones are causing problems. I tried importing an MP4 video recorded on my phone, worked like a dream. Could it be that the Win 10 screen recorder updates have brought about this problem?

I have this problem too. The MP4 videos I've worked with before import ok still, but the latest one doesn't. Has anyone had a response from Adobe? I'm wondering if this is me or a bug.

I've just started having the exact same issue, some (not all) of my MP4 video/audio files will only import the Audio??? 

I can select to two MP4 files created from the same source and one will import just fine, the other imports as audio only.  Both files are valid video/audio files and both files will play thru Microsoft's Win 10 video player so I know the files are not the problem and this appears to be specific with Adobe.

Can someone point me to a link where I can submit an official support ticket.   This issue only started happening today 2017.1.2, v11 Oasis.  11.1.2 (22) Build.

Cheers, Rob.

I had this problem with a project I had open over night and just restarted Premiere and reopened my project and importing was working again.  (Note I also cleared cache before restarting, but I do not think it did anything as after cleaning I tried importing with no success)

I am going crazy to try and find the answer to this. I was using CS6 with my Canon T5i and it read my video files completely fine! Now that I am updated to CC it only imports my files as audio. Everyone one says, re-download QuickTime, or that PP can't read H264 but it was working before and now it won't! This is such BS, this program is expensive. I go through a lot of video, I don't have time to convert each one.

changing the file extension to mov

Try changing them to mpg.

And on a side note dont every install codecs (unless you need a particular one like mjpeg etc) as they can realy mess up your computer.
