max_seconds does not appear to be working

[hursey013]

Describe the bug I have set max_seconds to 30, with the hopes of saving smaller clips however when I review the saved clips they are often well over the allotted time (2+ mins in some cases).

Version of frigate 0.8.4-5043040

Additional context

[blakeblackshear]

The max_seconds setting is really managing the age of cached files, not the length of generated clips. There is 90 seconds of cached video for each camera built-in, and this setting is added to that 90 second baseline. With a setting of 30, any cached video segments older than 120 seconds will be expired when the process checks periodically. You can try reducing it to 0 to limit it to 90 seconds of cache.

Got it - thanks for the clarification, I'll give setting it to 0 a try and see how that works.
