DPX Sequence Numbering control

[Bob Gruen]

Is there any way to control the numbering of the files geneated by a DPX sequence export? For example, is there a formula syntax that can sub in frame number and set the length of the padding?

Anyone know why frame number isn't stored in the dpx metadata?:banghead:

From ImageMagick:

Properties:

date:modify: 2012-12-13T13:06:32-05:00

dpx:file.ditto.key: 1
dpx:file.filename: Music00000000001728
dpx:file.timestamp: 2012:12:13:13:06:30:EST
dpx:file.version: V1.0
dpx:film.frame_rate: -1.#QNAN
dpx:film.offset: ÿÿ
dpx:film.prefix: ÿÿÿÿÿÿ
dpx:film.type: ÿÿ

Timecode is stored in the header. What are you trying to accomplish? By frame number, do you mean the frame count of a given frame from the start of the source file?

I mean the frame number from the start of the sequence being exported, not starting from the beginning of the range within the sequence being exported.

I am getting ready to create a DCP of a 90 minute feature and I have the entire film in a master sequence for export. I want to be able to export it in sections, but because the export file names always start at 0 padded with enough 0s to cover the export range only I cannot do this. If my entire film is 123,000 frames and I want to export a chunk out of the center (say 100,000 to 110,000) it won't be numbered properly. Instead of getting FN100000.dpx, FN100001.dpx, ... FN110000.dpx I get FN00000.dpx, FN00001.dpx, ... FN10000.dpx.

I can correct this through a batch process, but I have to prompt the user (myself) for the beginning number of the range, which introduces the possibility of a mistake being made. If the full sequence frame number were in the metadata I could use that instead of prompting the user an be assured it is correct, but I couldn't find it there either.

In the past I have worked with software packages that provide a formula mechanism for batch file naming, I web-searched for this functionality in Premiere but came up dry, so I suppose it's not there.
