Because renders take so long, it would be nice to be able to pause a render and restart it even after a restart, I have to do other things with my computer causing renders to fail. it would be helpful to be able to stop and continue a render.
I would like to see this as well, I know it is not simple, any changes in code can create unwanted side effects but this feature is important and I think worth it.
What I’ve been doing to pause the rendering process is use Process Explorer and suspending the ffmpeg.exe process, then resuming it. On my tests so far it seems to work really well, no crashes, but use with caution. That is for Windows users, of course.
On Mac, you can open your terminal and do the same:
ps aux | grep ffmpeg - take note of the PID of the process
kill -SIGSTOP PID - to pause the process
kill -SIGCONT PID - to resume the process
Good to know it is possible, just need to implement a button on the interface.
