When exporting a large amount of frames is there a possibility to track the duration of this process?

I'm currently setting up a Sublime Text 3 workflow and I was wondering if I could get print out some feedback of when the build is started and when it is ended?

The code below gets called when the saveImage is done building. Is there a way to bind another callback function to saveImage?

os.system("open --background -a Preview " + EXPORT_PATH)

Thanks in advance!

this should give you the perceived execution time of script:

import time

start = time.time()

# do something

end = time.time()
print(end - start)

there are plenty of options to have some sort of process bar that gets updated for each frame:

see https://stackoverflow.com/questions/3173320/text-progress-bar-in-the-console#

If this doesn't makes sense I can narrow it down to an simpler example!

good luck!

@frederik makes sense! I can easily print out the progress of executing frames but I can't figure out how I can get some kind of progress feedback when the saveImage() function is called when exporting a larger .mp4 file. Any ideas?

oh, there is indeed no progress callback on saveImage(..)

Doing some googling on 'progress' and 'ffmpeg' does not results in a clear solution.
