    IFL files

      I was a bit surprised to see that After Effects CS3 can't load IFL files (I was pretty sure that version 7 could, but maybe I just assumed). In other words, there doesn't seem to be any way to load image sequences where the files are not named sequentially. This is extremely useful when trying to load (for example) sequences of satellite images, which are typically named [satellite]_[yyyy][mm][dd]_[hh][mm].[ext] (ex., "mysatellite_20080301_0745.jpg"), but where the numbers aren't continous (ex., after 0745, the next image might be 0801, because it was taken 16 minutes later).

      IFL files (used by all major compositing packages, AFAIK - I know Combustion and Fusion can load them) are simply text files where each line lists an image (or video, or other IFL file), in the sequence they are to be loaded.

      Does anyone know of a plug-in to make After Effects load IFL files?

          No idea. The last time I used IFL was in 1995 in Animator Pro for a sequence rendered from 3Dstudio (for DOS). I think the loader was tied to the old FLI/FLC stuff which indeed was killed off with CS3. I would guess that if you really need it, you could re-create it with scripts.

            No support for IFL, sorry. However, you could pretty easily rename your files with one of the many free file renaming apps out there. Rename the end of the file name based on something like the EXIF metadata in the file, and you're set to go!

              Why would you need an IFL for that? 3D Studio creates sequentially numbered files.

              Renaming the files isn't an option; the file name contains relevant information, and duplicating thousands (possibly millions) of files (to keep a renamed version just for AFX) isn't viable, either. I guess I'll just stick to Combustion. It's really odd that AFX can't do this.

                I think this had more to do with Animator Pro than the old 3DS. I can't really remember the exact reason. It's just too long ago... ;-)

                  Couldn't you just append a sequential number at the end of the file name? Duplicating the file seems unnecessary.
