How well do you know the Image Sequence node?
Maybe I’m a bit slow, but it’s taken me a bit of figuring to get the hang of how frame sequences work in the Image Sequence node of the compositor, and I’m pretty sure I’m not the only one.
In any case, I finally decided that what I really needed was a sequence of frames with visible frame numbers that I could play around with, and that helped a lot. If anybody is interested in testing their skills with this, you can download a simple little exercise I put together here.
The tricky part for me was to figure out what, exactly, the fields “Frames”, “Start Frame” and “Offset” refer to. What do you think? Is this ridiculously obvious, or did it take you a few tries to get the right values in those fields? Do you see more than one way to get the solution?
Once you know how these fields work, it’s pretty simple, and I admit I’m not sure offhand how I’d go about making the interface more intuitive. (Although I would definitely prefer that the node were able to suck up multiple frames automatically, as when importing strips into the sequence editor.) There does seem to be some redundant functionality, but maybe that serves a purpose I haven’t come across yet. Anyway, I found playing around with this sequence to be helpful.
If you want to generate similar sequences with other frame numbers, here’s the .blend file I used to make them. It’s simple, but maybe it will save somebody a few minutes.
