I'm rendering a large animation on a laptop. And I need to turn off rendering on certain frames (they are repeated). For example, from 5-10 further from 15-20, 21-25. I plan to simply duplicate the missing frames rather than render them. I got acquainted with blender 1 month ago. sorry if it's a stupid question.

    There is for sure some script or addon for such thing ... Or you can create a dummy files (just copy files numbered in range you want to skip from any existing image sequence) and under Render Output Properties disable Overwrite checkbox. – vklidu Dec 21 '23 at 18:58
  • Thank you, I did the same before reading your answer. I made empty frames and renamed them sequentially. It's good that I only have ≈100 frames. I made shortcuts and used the Tab key to sequentially enter the numbers, 0987, 0988, 0989... It's tedious :)But it works – Vladimir Zhelovanov Dec 21 '23 at 20:24

  • It's crazy, I honestly searched, but didn't come across all this. Thank you – Vladimir Zhelovanov Dec 22 '23 at 15:27

If you render from the command-line you can pass a list of frames that include ranges, like (assuming your last from frame is 250), omitting the frames you don't want rendered:

blender -b "my.blend" -f 1-4,11-14,26-250

    Thank you. Unfortunately, I have already done as the author wrote above. Fortunately, there are not many frames. I still have to master the world of scripts and Python. I'm pleased with how responsive Blender communities are :) – Vladimir Zhelovanov Dec 21 '23 at 20:28
  • @VladimirZhelovanov -- realize that the above is a windows or linux command line, not a python script. I actually do a lot of my animation rendering using .cmd/.bat files. These can run in the background ("-b" option above), using less memory (no UI appears). Here is the doc – james_t Dec 22 '23 at 20:56
  • This is the first time I've heard this. Very interesting, thanks – Vladimir Zhelovanov Dec 23 '23 at 21:12
