How do I render every other frame and have them numbered 0,2,4, etc.
I’d like to render half of my comp – every other frame – to verify that there are no mistakes (it takes a few hours). Then, render the other frames and merge them. I thought I was so smart rendering 15 fps to an image sequence, but it numbers them 1,2,3,etc. instead of 1,3,5…
Is there a way to get AE to render frames like we do in our 3D apps?
IF I can’t get it to correctly name the frames 1,3,5, etc. Is there a way to render 15fps starting at 0 and then again starting at 1, then merge the renders and use a flickering solid to knock out the top layer every other frame? I tried this last night, but for some reason whether I started at frame 0 or 1 I got the same output.

Thanks, Dave.
Specifically, I wanted to use the first night’s render as a double-check of the entire sequence. If it looks good, then I’m half way done!Antifreeze Design

I don’t know how to render every other frame from After Effects. But I do know it is a legitimate technique to check heavy renders, especially for 3D work.
If you ever figure out how to render every other frame you can then use the ‘skip existing frames’ option to go through and fill in the empty spaces.
If there is no way to get After Effect to render skipped frames, you could always do your frame rate trick, and then write a script in Automator or Bridge or something that renames the files with some maths. I think the maths would be (x*2)-1 but check that.

I looks like it can be done if you launch the render from the command line with increment flag
increment is the number of frames to advance before rendering a
new frame. A value of 1 (the default) causes normal rendering of
all frames. Higher values render a frame and use it increment
times in output, and then skip ahead increment frames to begin
the cycle again. Higher values result in faster renders but
choppier motion.I’m looking at page 610 of the After Effect CC manual.
