Try a different output module. In
this thread changing it to "Open GL video output for Windows" worked for that user.
If none of them work please create a log file as follows.
- Before starting a video hit Ctrl + M to open the Messages window.
- At the bottom of the window change Verbosity from 0 to "2 (debug)"
- Leave it open and go play a video.
- When it finishes, go back to the Messages window and either click Save As, or place the cursor anywhere in the log and hit Ctrl + A to highlight followed by Ctrl + C to copy it to the Windows Clipboard.
- Next, go to https://pastebin.com/ and in the New Paste window on that site hit Ctrl + V to paste the log you just created. (no need to create an account there).
- Scroll down to the bottom, give the pasted log a name and click the Create New Paste button. That will change the URL at the top.
- Copy that URL and paste it here into your next post.
If you prefer, use the context menu right click --> Select All / Right click ---> Copy and right click Paste instead of the keyboard commands, but I'll leave that up to you.
