Sony Vegas Pro (14): Suddenly, mp4s have no video (resolved)

peachysaurus wrote on 8/10/2020, 8:56 AM


I've been using Sony Vegas Pro (14) for a few months now. I've always been able to use video captured straight from my computer and have never needed to convert the video files in order to use them properly. For some reason, last week, SV refused to accept that my mp4 files had any video, and only displayed the audio tracks. I hoped it was a fluke with my recording software that day, but when I tried to import another mp4 today, I found that I had the same issue. The files I use are really big and I don't want to have to spend hours converting them into a useable format every week. When I play the files in a video player, they have both audio and video.

I've searched around on this forum for a bit, but I haven't been able to find a solution that answers why it just suddenly stopped working. Here's the latest .mp4 that I tried working with. Any help or suggestions would be greatly appreciated!

Thanks for posting the Vegas file properties.

Also needed are the MediaInfo properties so we can determine other parameters. Also tell us about your "recording software." Do you mean screen capture, broadcast recordings, what?

peachysaurus wrote on 8/10/2020, 11:47 AM

The software that I use is the default, screen capture that comes pre-installed on computers with windows 10 (xbox game bar is the official name).

Also, here are the MediaInfo properties. Thank you for the response!

Looks fine. In these cases sometimes a simple re-wrapping with a tool like FFmpeg helps.

peachysaurus wrote on 8/10/2020, 12:17 PM

Thanks Marco, any suggestions on what format I should convert to?

Marco. wrote on 8/10/2020, 12:18 PM

First I would try just re-wrapping without transcoding into another format. It is likely there's only something wrong with the wrapper, not with the videostream itself.

Are you familiar with the use of FFmpeg and do you have it installed? I have several FFmpeg scripts for re-wrapping available.

I've never used it before, but I have gone ahead and installed it. I'll try to get familiar with it :)

Then copy & paste this code into an editor and save it as "remux.bat" file.

@echo off
if "%~1"=="" goto done
ffmpeg.exe -i "%~1" -c:v copy -c:a copy "%~1_new.mp4"
goto next

Once done simple drag & drop your MP4 file onto that BAT file. Then try if the new file with the name extension "_new" does the job in Vegas Pro.

You're an absolute life saver! Thank you so much, it worked perfectly :)
