Windows 10: MP4 file is at low opacity and when i try to play it it just doesn't work.

I have a very important MP4 file on my computer and just recently I went to open it and its opacity had gone down to around like 50 or something, I didn't think much of it but when I went to open it, it would not play. Does anyone know what this means and if there is any way for me to fix it?

Windows doesn`t start. Authomatic repair doesn`t work.

Thanks again!!

I`m sorry I had not noticed that the text on the picture was in spanish. It says that windows has replaced some damaged clusters in "name" file and "directory". Then, at the end "an unspecified error occurred (75736e6a726e6c2e 4f6)".

I`ll do it and I`ll be updating this thread when I have the report.

I ran SeaTools. These are the results:




Does it mean my HDD is useless?

 

MP4 File will not play

Based on the information you have provided, considering that you are encountering the same issue when playing the MP4 file on different applications, then it's possible that the issue is with the file itself. This could be caused by an interruption or an
issue while the MP4 is being copied. I suggest that you create a new copy of the file and check if the issue persists.

Let us know how it goes and we'll assist you further if needed.

 

Play MP4 in Media PLayer


I am using mp4 files myself. Rather heavily. The files I have use the native h264 codecs for video and also something pretty standard for audio and they work. MP4 is a container format and I vaguely remember I once had a file, that did not play.

I am not a real expert here, but you can try this:

Download the static Windows version of ffmpeg and check your mp4 file with ffprobe.exe. It will output a bunch of information about that file, including the codecs used inside it. Knowing these codecs is a first step on the way to a solution.
