MPEG-2 rendering video with audio but no images.

My computer can't keep up with rendering to lossless format, so i chose MPEG-2, to render video with VCV-Recorder v.1.1.0
Here's the procedure i made in VCV Rack:

1. Connected its L & R inputs to signal i wished to capture as audio.
2. From its context menu, i…
   • Defined an 'Output file' via its context menu.
   • Selected the 'MPEG-2' video format.
   • Tested export with default encoder settings, then with the following;
     • All Audio bitrates between 128 & 256kps
     • All Video bitrates between 512 & 2048
3. Pressed the big Record button to begin capture.
4. Pressed the big Record button again, after some time elapsed, to finish capture.

The resulting file loaded and played in Windows Media Player and another video player (JetAudio). The sound was audible but there was no visuals. i assume that the contents of the Rack's window is intended to be captured?! i attempted recording with Rack both in fullscreen and windowed. i also attempted recording after removing scopes from the Rack, in case they caused conflict.

Environment:

• VCV-Recorder v.1.1.0
• VCV Rack v.1.1.6
• ASIO soundcard
• AMD Radeon HD 5450
• Windows 10 Home

Can reproduce. MPEG-2 videos from VCV Recorder can be opened in mpv, VLC, Quicktime, and many video editors, but video does not display in Windows Media Player. I've hardly used that software, so perhaps it only supports a subset of the format, or perhaps VCV Recorder is producing a non-compliant file.

Thanks Andrew 👍
i installed VLC and made a quick recording in VCV Rack. An audio-visual capture was successful.
Glad to have a jukebox alternate to Windows Media Player too!
