Can't read MP4

PostThu Aug 03, 2017 2:43 am

So I had a bunch of projects in DaVinci Resolve 12.5, with .mp4 clips imported to the media pools and timelines. All of them were working properly. They played fine and all. I always used to import .mp4 (H.264) files in Resolve without encountering any problems.

But suddenly all the imported media files in all projects went "Media offline" when I was eating chicken nuggets this morning. I did not rename, move, or modify any video file. All the clips are where they were before this issue came. I did not tamper with the video files. So why did this happen?

Also, ANY .mp4 file wouldn't even import in Resolve anymore. Unlike before, when they worked fine. I also tried dragging a new .mp4 file (which is what I used to do to import) into the media pool but nothing happened. The video didn't import. The video didn't appear in the media pool. Again, I had no issues with importing before.

What I have tried:
-Restarting computer
-Deleting CacheClip folder and all its files within it
-Relinking clips (still didn't work! Weird!)
-Dragging in a new .mp4 file into media pool
-Changing media storage directory in 'Preferences'
-Exiting and relaunching DaVinci Resolve 12.5
-Making sure that the video files weren't renamed or changed
ALL OF THESE DIDN'T WORK FOR ME

Additional notes:
-Imported audio files still work. They play fine.
-How can I reinstall DaVinci Resolve without deleting the projects? I still need my projects.

Have you tried eating a new batch of chicken nuggets?

But more seriously, I have searched far and wide on the internet for a solution, I have the same issue, only I installed the program and it did this to me straight away (no chicken nor nuggets were involved). My suspicion is therefore, that said chickens and nuggets might not be the cause of our shared misery, but rather some codec problem. Not one that wants to be resolved, it appears. Have you also an amd card with ample memory and a cpu with amazing prowess in crunching numbers?

All I need the program for, is editing my phone's video. Transcoding the format did not work for me, but I am a noob in such matters.

I wonder if anyone will respond with a solution, since it is getting me down.

It's almost certain that your phone is recording variable framerate video. This won't work in Resolve, but I hear it's supported in more consumer oriented NLEs like Sony Vegas.

Can you see the mp4 files on the Media page in the Media Storage area? If you select one, does it appear in the Viewer?

Can you send us the info mentioned in this thread?

We don't support Windows 7.

You can install this Win7 update, if it's not already on your system, and I would guess it would have a good chance of fixing this specific issue.

Windows won't let me install that update, since they are a cancer to everything that is good and nice.
How disappointing all of this is. I spent more hours trying to get it installed on Tumbleweed, which is an opensuse distro.
Let me guess: it isn't supported.
I'm going to give up, it is obviously only meant for a certain kind of user, which off course, I am not. :|
Thanks for the advice given.
Uninstalling.

Works very well on W10. Or a Mac.

I actually bit off even more of the bitter bits and installed windows 10.
So no, it doesn't. Maybe I should buy a Mac to use this program?
I mean, come on! :cry:

Can you upload a clip for testing, to a service like Dropbox or WeTransfer?

Even if i'm on a Mac, I'd like to have a look at what might be the problem.
