Computer recording wont render out

[zaphodikus]

VS2021
is there a log file i can look at for clues? I been struggling with computer screen recording clips jsut crewing up VS when i add them to the timeline, so i decided to try see if simple converting the file in VS by rendering it out fixes the file.

I have a computer game recording, and if all I do is drag it into timeline (4 minutes) , click share and then start rendering, it silently fails. the render progress just ends after about 2 seconds. I get no error or no "done" bos appearing
I took the file and got ffmpeg to convert it to 60fps, and replaced the only clip on timeline with the new 60fps file and same issue.
hardware acceleration is off, file has a smart proxy generated for it. File is MP4 container, H264 29000kbps data rate for the video , AAC audio,
24bit color 2560x1440

This conversion had no effect on the results I get either.
ffmpeg -i <input> -filter:v fps=30 <output>

As the video recording is using an odd frame size, although 16:9ratio. I would try using the overlay track to hold the video recordings
First set the project properties to one of the mpeg4 default profiles, HD or 4K
Insert the video to the overlay track, fit to screen
From share – same as project settings

Oh my sainted aunts. When i played this clip, the audio was silent, so i knew something was off. the recorder had recorded the HDMI screen audio device. LOL
which was silent or something.
ffmpeg <input> -c:v copy -ac 2 -c:a aac -b:a 320k -ar 48000 -y <output>

Fixed the file (I've since fixed my default audio capture devices)
Next time I add a clip with no sound into Studio, I will know better for next time I would hope.
/edit I'm suspecting the audio stream was broken or stops in the stream with no data in it, which would explain why VS did not like the video clip, I've had silent clips break the app before.
