Comment (by Jordan Fearnley):

 I've just done another test run now with `-c:v h264_nvenc` to confirm,
 albeit using a different input source. I get the same issue as initially
 reported when doing it this way as well so it appears this isn't just
 limited to hevc.

 I also sent off the binaries of ffmpeg I've been using to test this over
 to an associate who has a 40 series GPU, and it looks like this issue does
 not occur when using `-c:v av1_nvenc`. The same issue could still be
 reproduced when using `-c:v hevc_nvenc` on this other device, so it looks
 like it's just h264 & hevc that are impacted.


 For the sake of completeness, I've done a quick test using `-c:v libx265`
 to ensure that this issue doesn't occur - outcome is as expected and there
 are no problems occuring in this scenario.
