I have a looped animation. On the first and last frames, there is nothing but a plain backdrop, and the object appears sometime during the middle of the animation. I'm rendering to an image sequence, then compiling to .gif with the help of ScreenToGif.
The problem is that the .gif thumbnail shows the first frame, which is the blank backdrop. This is especially problematic because I have multiple works in a series, and all of their thumbnails are the same blank backdrop. The animations are all 168 frames long. My workaround is to manually import frames 60-168 into ScreenToGif, then to import frames 1-59. However, this is fairly inconvenient. I've also tried shifting the keyframes to achieve the same effect but, again, it's a substantial amount of unnecessary work.
Is there a way to render frames out-of-order and effectively renumber or remap the frames? For example, I'd like to save frames 60-168 as
frame[0001-0108].png, and frames 1-59 as
Is this possible?
