FEATURE REQUEST: Symlinks

Post by igit »

In the latest version, I tried to combine several trailers and a film into one OV DCP. The trailers and the film were in the same format Scope, interop, 24fps and not encrypted, as well as all the materials were on the same HDD. On it, I created a project, added trailers and a film and clicked to create a DCP OV, but the DOM began to repack MXF.
Is it possible to create symlinks to the original MXF so that the size and hash data are taken from the original CPL? Then the process of creating DCP would be much faster.

I'm not sure I follow your question. You want to end up with an OV, which has a single MXF containing all your trailers and your film?

I wanted to combine several DCPs into one OV without repackaging and transcoding

No, not one mxf - multi mxf, by one for eatch added video

Sample:
1. i have a Feature OV - 1mxf video + 1mxf audio
2. i need to add 3 trailers before feature - 1mxf video + 1mxf audio for each trailer
3. need a final OV with 4 reels without repackaging and transcoding

Ah, I see. OK, here's a feature request; let me know if you'd like to edit it and I can make you the "owner".

May work, but sounds like a critical operation. I mean, these files could be anywhere, also on removable drives? After DCP creation, the only reference is done on the file system level, there is no further checking for consistency? I guess this is also difficult to enable in the GUI?

I voted for a separate application to organize DCPs on the File level a long time ago (can't remember wether that idea made it to Mantis). An app that would allow e.g. rewrapping, repackaging (e.g. pack multiple CPLs/VFs into a single DCP). Maybe that would be the place to do such things?

Sorry for delay, many jobs,
Symbolic links on Windows only work inside a volume. I think there should be no problems.
I tested 2 professional programs - ColorFront Transcoder and Marquise MIST. They just implemented work with symbolic links.
Moreover, if different disks are indicated for MXF and the final DCP, then the program will copy the MXF files. This greatly saves time.
Especially when the files have the same parameters, you can not rewrap them, but create a link and transfer information about the HASH Key, etc. from the original CPL.
