Hey Adam,
Thanks for the suggestion. To clarify exactly what I'm doing:
When the IR sensor detects motion, I update the configuration for the
Motion daemon to set the following two configuration values to "on" for the
camera in the room the IR motion was detected:
ffmpeg_output_movies
emulate_motion
It was my understanding that as long as the emulate_motion is set, then I
don't need an actual motion event, nor significant post-event recording
value to capture the motion.
Basically, I toggle on "record videos" and "always record regardless of
motion" and for whatever reason it is producing corrupted video files of
the correct runtime, just not content.
Best,
Jon

As well as pasting the section out of the log where it says the disc is full,
open a terminal and type
df
and copy/paste the result here
To copy from the terminal window you have to use Ctrl+Shift+C, in case you did
not know.

Ok, thanks. I?m pretty new to Pi. I?ll read through the log and see if I can
find anything out. The only thing I saw was something about an error ?that the
drive it was trying to write to was full and if I open it it says 29.2 GB left.?

Do you think I should try I different brand of pen drive and see if has better

I think you should analyse the problem in the ways I have suggested first to
get some sort of handle on what is happening.
