Hello all,
When I recieve a DCP, usually it consists of the feature 5.1 (OV) and 7.1 (VF).If you need the 7.1, how do you ingest? ingest the 5.1 first, then ingest the 7.1; Or just ingest the 7.1 ???
The same with the non sub feature and sub feature
???

Duc:
Yes I ingest the 5.1 first and then the 7.1. I have also ingested them both at the same time without any issues.

Thanks,
Robert

The 5.1 and 7.1 are separate and complete DCPs. It makes no difference what order they are ingested. If you use the CC or OC versions, sometimes you have to ingest the FTR version before the CC or OC.

There is really no ingest at the same time when it comes off of the same hard drive. The important thing is that the OV version (original Version) is down loaded first. In this case the 5.1 version because that has the entire content for the movie. Then you download the 7.1 version. That only has the sound related files for 7.1. This file is then joined with the original file and this is the one you would use to run on the playlist.

We don't use the 7.1 at my location but I thought you had to do the 5.1 first. Anyway to verify this look at the end of the file name extension of the 7.1. If it has a VF at the end then you will need to download the 5.1 first then the 7.1. If it has an OV at the end then you only need to down load the 7.1 version.

If the 7.1 is a "VF" (Version File) you need the "OV" (Original Version) on your server as well, which usually is the 5.1. Doremi SW should take care of it, hence if you load a VF and the server realises that the linked OV is not loaded, it will load it for you.

Unless the 7.1 version is another OV - complete DCP, which would be a massive waste of space! - and in that case you can just ingest the 7.1.

The general rule is to ingest OV first and then the VF even though - as said - modern software will take care of it.

A "VF" is a CPL which only add the relevant bit of content. For example, the 7.1 VF adds the 7.1 soundtrack but will read the Video track from the OV. A subtitled VF works in the same way: there is no need to create a new DCP - 200GB-ish - for adding only a few kilobytes of subtitles: they would usually create a VF which when played uses Audio and Video of the OV and just adds the subtitles track.

The last three 7.1 features I have run in my theatre (Croods, GI Joe, and Oz) have all been OV 7.1 DCPs. This is the norm, as far as I know, because I have never had to have both the 5.1 and 7.1 versions present on a player in order to run the 7.1 content.

You're running a Dolby server there. Just ingest the version you want. The server is smart enough to get what it needs. There is none of this "ingest this one first then that" nonsense.

Justin, take a look at the CPLs on your disk, it's very possible that they're named OV but they're in fact VF's.
If they were OV's, that would mean that you have two big DCP's on your disk (two folders, two video tracks), and that is just a big waste of space and time.

I think with some older doremi SW if you ingested the VF without ingesting the OV first, the ingest process would be successfull, but the CPL would not show on the cinelister. After ingesting the OV, it would re-appear though! [Smile]

I think that's why the distribution is still recommending that silly procedure!

Marco, that is not the case. The DCPs for the 5.1 and 7.1 are almost the same size - the 7.1 is maybe 3GB larger. Plus, my LMS only sends the 7.1 to the player.

I guess it's possible they are sharing a video file, but nothing I'm seeing suggest that much.

All the versions usually share the base video file.

If we ever copy more than one version on the second one takes like 2 minutes to copy because most of the content is already there.

This is on a Dolby server

If you look at the distribution drive contents on a computer (not the server) you'll see the OV folder has the image files and sound files. The "VF" folder just has the sound files (both have the other assorted files that make up a DCinema package). Some servers look at the CPL and link to missing files if they're found in another folder. Dolby servers do this. Doremi servers do not: if you load the VF without the OV on a Doremi the content will not be complete. Once the OV is also ingested a Doremi server should find the missing files and be able to play the movie, but it's safer to ingest the OV first.
Anyway, if the image files are identical they are not duplicated on the drive even though it looks that way on a Dolby server.

I use server Dolby. I know (I had did this)that if we ingest only the 7.1 (VF) or only the sub ver. (VF) , everthing will OK. Dolby server will help me. But What I care is "Does the 7.1 sound effect lose?"
tks!
