Image Sequence File Naming for Conforming Digital Intermediates
Here’s an example filename of the first image sequence file that corresponds to the EDL
event shown above:
my_file_name.0494794.dpx
The first portion of the filename for each scanned frame (the alpha characters) is
ignored, but the numeric extension listing that file’s frame number should equal the
(non-dropframe) timecode conversion of that value appearing in the EDL.
For example, a frame with timecode 05:51:18:28 would have a numeric extension of
632368. Numeric extensions should always be padded to seven digits; in this case, we
would add one preceding 0, like this:
my_file_name.0632368.dpx
Only the numeric extension and the .dpx or .cin are strictly required, since the initial
alpha characters of the filename are ignored by Color. For example, the above filename
could also be:
0632368.dpx
Alternately, you could utilize the unused first portion of the filename to keep track of
the reel number that frame file comes from:
reel_004.0632368.dpx
