I'm trying the free version of Bandicam to see how it performs.
I have it configured how I want - resolution/quality/audio etc.
I have tested that Game mode works using the F12 hotkey. I have successfully recorded a short game video.
I started Apex Legends, hit F12 - the FPS counter turned red. I started playing.
I played one game then exited to desktop.
I realise I forgot to hit F12 to stop the recording.
In the Bandicam Window, I hit Stop recording.
After a couple of seconds, I am shown an error message saying that Bandicam is unable to stop the recording (or similar message), and did I want to force stop, I selected Yes.
The resulting video was 0 bytes in size...
