making prores into avid MXF on a MAC>>

[Jason H]

anyone know how to make prores 422 into avid MXF on a MAC? With timecode preserved?

thanks for any positive responses in advance.

First off you will probably need to use Metacheater to create the ALE to preserve metadata.
You could use Metafuze on windows or on MAC thru emulation to create the MXF aware media and generate an ALE. You would need the ProRes windows component to read the ProRes for Decode.

With AVID MC5 coming soon this will be unneccesary as you will eb able to natively use the ProRes inside AVID with no transocding.

i Know this is a repost, meaning you're probably at ends wits right now. Honestly, the simplest way but (not very cost effective way) is for you to lay off to tape in a dub or post house some where, and than reingest it into a avid system. Yes it costs money, but at the moment, that seriously is the easiest way to do it, and the fastest.

can't you just import ProRes 422 files directly into Avid and it will preserve timecode?

that was my understanding.

Export the ProRes files to DNxHD QTs using QT Pro

Check the timecode track, if it has been re-set to zero use iTimeize (http://timecodesoftware.com/itimeize) to re-generate the timecode as per your original ProRes files.

Create an ALE using Meta Cheater

Batch import the DNxHDs into Media Composer and let it create the MXFs....

Hopefully should work.

Thanks to all of you for the help guys!

Yes you can import the prores directly into avid. The edit house was trying to save a minute or two( literaly) by getting MXF files from me as they are used to getting the MXF files from a color house in chicago that uses baselight as their color ap ( i use apple color and will soon try out the new Davinci resolve for mac).

I guess making MXF files is part of baselight? I'm not sure how they are doing it. They might just have an avid there and be doing the post house a favor by making the MXF files on their end b4 they send the files back up here to Milwaukee.

Either way I went to the post house today and watched them take my prores files ( for a 30 sec spot) and import them into avid so they could sub out the non color corrected MXF files they were editing with. It did not take that long and the time code was the same on my prores files as the files the subbed out. All is well! I think they were just used to getting MFX files back from the color house with baselight. I just wanted to be able to do the same. They seem to be just fine with the pro res files and the import time since it is just a 30 second spot.

Baselight is a licensed Avid partner and has been able to read and write Avid MXF files using all flavors of DNxHD for quite some time now. This is also true of Digital Vision, and more recently, Assimilate Scratch (although that's not in the current release version 5.0, it is in the next one, 5.1 - right, Lucas?).

Automatic Duck?

Automatic Duck?

You could just use Automatic Duck Pro Export in Final Cut Pro? My only problem right now with it is that I'm getting a Gamma shift when I do that, the black levels are brighter in the MXF than in the source Quicktime.

I just got a graded film back from a Baselight system running the latest version [3.1?], and the colourist was apparently unable to export a DNxHD 185x file, owing to a bug.
Being unable to import a DPX sequence on our Mac based MC, I found myself having to import a Prores file instead.
Ironic really.:embarassed:
I hope it didn't mess with the gamma levels?

…a Baselight system running the latest version [3.1?]…

The latest version of Baselight is 4.2

In my testing MC5 reads ProRes files correctly with no gamma issues, so if the ProRes files are correct in FCP, they should be correct in MC5 too.

Was the ProRes file created in Baselight with Kompressor, or created from the DPX sequence using another app.

How are you making this determination?

What most people commonly refer to as "gamma shifts" is really a matter of how each player environment presents the file to the user interface display, not how the file actually looks. QuickTime Player uses color profile information to "optimize" certain files to "look good" on the computer screen.

Thanks for that Nick.
I'll check - grade was done at filmlight in london - do they make Baselight?

Yes

If I understand it correctly, with the new media composer v5 there is no need to use other software to import the prores into the avid. Is this also true for the timecode?

The reason I am asking this is in another thread. I am having very serious problems to transcode some RED files (within AMA and also through CINERED X) into DNxHD. So I have been suggested to make the RED into final cut, and then take the pro res into the avid. I am tempted to use them, but I am worried about the metadata. Because I am only doing the offline, so I will have to provide an EDL to conform in other house.

Thanks.

What are the issues with AMA to R3D or REDCINE X to MXF/DNxHD? Both those methods provide the timecode and a lot more metadata and eliminate an additional transcode pass.

I absolutely agree with you. This is not the prefered way, but for the moment, I am not able to convert to DNxHD from RED. The issues are the same that I explained in this thread

I did not pretend to duplicate the thread, but as I am in a hurry, I am starting to think about these weird workarounds. And as your were talking about prores...
