I have the same problem. My workaround is to download the images and use this tool. https://timelapsetool.com/

Yep I have this issue too -- the timelapse successfully rendered exactly 10 times, then hasn't worked since. grepping through the logs shows timelapse.py:render() is already running a bunch of times, and this persists across reboots & restarts of the systemd services.

Interestingly, the last successful render kicked out this error message that I missed at the time because the video did render:

Edit: I deleted my gcodes and it's now rendering again, perhaps the single ' in a gcode filename is causing render() to persistently fail?

I got bit by this, I believe it may originate at https://github.com/mainsail-crew/moonraker-timelapse/blob/main/component/timelapse.py#L630 where the filename of the originating gcode is interpolated.

The filename I printed when I got bit was "joe's-synth-stand.gcode" and problem is related to the filename including a single tick character.
