First time. How much disk space will I need. Can it be recorded direct
to a USB drive?
Any suggestions would be much appreciated.

For a video at 1920x1080 resolution (Full HD) and 30fps, the storage
space needed depends primarily on the bitrate and length:
A typical bitrate of 5 Mbps at 1080p/30fps will produce about 37.5 MB
per minute of video. This means you need roughly 2.25 GB per hour (37.5
MB x 60) of video storage.
Another estimate suggests between 1.2 GB to 1.4 GB for 1 hour of 1080p
video, likely varying based on compression and encoding settings.
For streaming data estimates, 1080p at 30fps uses about 2.03 GB per
hour, which aligns with the above storage values.
Higher estimates (around 124 MB per minute or 7.44 GB per hour) may
represent less compressed or higher-quality settings such as those used
in certain phone defaults

It may depend on the vintage of the camera.
Not all the C920s are created equal. And this removal is not an accident. It's quite possible the hardware still does this, but, the compressor
was pinned off.

Another reference I could find says 5 megabytes/sec for MJPEG on a C920. Which is not a lot of compression. That's 2.5x the rate I would want to see. That's 18GB per hour. Sure, it can be recorded direct to a USB drive,
but it could also flake out on you if the mood strikes it. It would have
to be a "very good quality" USB stick to work. It all depends on whether
the USB stick "has a bad spot" or not.
You could also check your computing device for an SD slot. Typical
values on older equipment are "10MB/sec max" and "32GB SD max".
Only newer devices have a version of SD where larger capacity
storage is available for purchase, at higher write rates. The
very best SD cards today, actually use a PCI Espress lane for
data movement. But nothing I have in the house would work
with one of those.
My laptop, I didn't discover I had an SD slot, until one day I noticed
a weird plastic bump in one corner, and that was a dark plastic "filler" which protects the SD slot :-) The casing was dark plastic, the filler
color matched the casing, giving no visual clue of the treasure underneath.
Cheese may be able to Transcode. For example, some (but not all) video cards have a video SIP with decoder and encoder, and if the code is written for
it, the data rate could be changed. MJPEG decoding is unlikely to be in
a video SIP, but the CPU can do MJPEG decide, and any better-quality transcoding, the video card can do it. But, the code has to be
written to do that.
Check and see if OBS could do this for you, solve your problem.
My digital camera won't shoot video forever. Even though the SD has
capacity left, it stops video recording after ten minutes.

Vintage? Interesting choice of words, GURU Paul.
I guess my two old cars are vintage. :-)))))))))))))

If I had the vintage C920, it would probably have Hardware H.264 Encoder.

If it's 18GB per hour, I'll probably return the webcam.
I have 6GB available on my HDD to work with. I could move the file to
an external USB drive after. Or, record track-by-track and do separate shorter videos. Yeah, that's probably more versatile.

This is a good suggestion from Paul. Also, if you need a video editor, kdenlive is fairly straightforward. avidemux is good too, especially since it doesn't decompress video to edit it.
Bother, doesn't look like avidemux is in Debian. Find it here:
