Issues importing iStock comps into After Effects So I'm downloading a placeholder video FLV comp from iStockphoto.com (right click, save-link as under any video preview). When adding the downloaded FLV to AE, it comes up with an import error, saying that it is damaged or unsupported.

It plays fine in VLC, so using VLC, I convert/save it to other formats, but it still will not play in After Effects. Closest I've come is by converting to MP4, which at least imports into After Effects, but shows the flat error green screen instead of the actual footage.

Anyone know how I can import an iStock comp into AE?
After Effects works better with codecs that compress each frame individually (intra-frame codecs).  FLV files compress across multiple frames (inter-frame), as do mp4 files.  If you can get your FLV successfully converted to a codec like ProRes, it should work correctly in After Effects.  FLV files are quite unreliable in conversion- there's a post here that might help - it seems most people use the (now deprecated) open source Perian codecs to get this to work:

Your best bet is probably to find source stock material in a format that is easier to work with (most videos on iStock are now mov/mp4 which should be easier to convert)

(NB - I'm not sure this is really an After Effects question.)
