I have a setup in the compositor that takes a piece of footage, does some operations, and outputs 3 difference files. Let's call them output A, B, and C. I have the file output node with added sockets to output each. What this gives me in the output folder is each output followed by the frame number. For example, frame 1 will give me A-0001.png, B-0001.png, C-0001.png.
What I would like is to alter the frame number appended to the output files so that instead I would have A-0001.png, B-0002.png, C-0003.png. Frame 2 would then give A-0004, B-0005, C-0006.
The end result would triple the number of frames of the animation and have them interlaced.
Is this possible with the file output node? Is it possible with a script?
(bpy.context.scene.frame_current - 1) * 3 + output_offset
(with output_offset being 1..3 for A..C. in your custom function. $\endgroup$ – Samoth May 2 '16 at 8:18render.use_file_extension=False
removes the extension, but the frame number is still added. $\endgroup$ – Martin R. Aug 20 '19 at 23:08
