create aaf from single OP1a mxf file

[ring4life70]

hello
I'm trying to automate the creation of aaf for my avid workflow, in ffastrans using commandline and CreateAAF Tool, is very simple to create aaf file starting from OP-atom mxf file, but to take advantage from the Avid AMA function, I want to create, aaf file starting from OP1a mxf file format.

Is there a way to do this?
Thanks for the help.

Hey,

hehe well creating an aaf of an mxf op1a would be kind of redundant
Are you sure this really makes sense? Unfortuanteyl i dont have Avid users here. Could you explain a little bit around this? Is this for Interplay or more like standard mcp?

correct starting from Avid Media composer 2019.6, UME ( Universal Media Engine ) is replacing the existing AMA functionality, basically UME provide native Mxf Op1a and ProRes RAW support, this functionality introduce a new UME folder, ( this folder is analog of MXF folder that contain OP-atom files ) where is possible to copy MXF OP1A or supported mov files, database files is created, and these files will appear in Media Tool, I'm finding a way to not use the avid media tool to find a clip in the UME folder, and my idea is to create a workflow that move OP1a mxf files into the UME folder, and create an aaf file linked to this mxf, I don't know if is possible to use createaaf command to create aaf from a single op1a mxf file.

Interesting, thanks for the insights!
So i checked it but unfortunately pyaaf2 is not able to link anything else than opatom (and limited even to a bunch of codecs).

There is an alternative linking function for creating aaf's containing AMA_Links. I needed to dig a little in the pyaaf2 source code to get it working tough.
Can you try if this works for you? If it works at all, there might be issues with the audio tough because i did set the "length" value (i assume it means duration) in the aaf to 0. Be aware, the linked location is F:\temp\rdd9.mxf. So in case it don't work, you might want to post me some existing location so i can fake the correct path for you and send you another testfile set.

Look in the samples/AAF_with_AMA.... Folder.

hi emcodem
thanks again for your support, your file is correctly recognized by my Avid obviously the media file is offline because we have different linked locations, and also because I'm on Mac
if you want a can upload in the same folder, an example of linked aaf to a single op1a mxf, generated directly from my Avid Media Composer

Hello ring4,
To be honest, I have some trouble to understand what is the utility to create a aaf. If you create a aaf linked to your new file, you will have to import it or drag'n drop it. You can as easily drag'n drop your new file (hold alt key and drop) into a bin and have it online.
I am still at AVid MC 2018 (cause I don't like the new interface from 2019) so I don't remember totally how works the UME, if it works like AMA or not but link a OP-1A is really easy and don't need to use a aaf file.
Maybe i'm wrong or I have misundertood your request ?

Sure, if you have a small file... the more infos i have the better, as usual
I wonder if it is possible to link a relative path, maybe your file gives me some more insights...

ok uploaded ! you can find them in the same folder, the mxf video file size is only 34mb.

thanks

ok, so your aaf links to this:
file:///Users/YOURUSERNAME/Desktop/TEST%20AAF.mxf

Please find new files in same location as before, subfolder "playaround".

I created 3 files for playing, please try all three and lemme know your results:
1) TEST AAF__samelinkAsOriginal__.aaf --> links to file:///Users/YOURUSERNAME/Desktop/TEST%20AAF.mxf

Code: Select all

If this first test does not work, the whole project is doomed and you can theoretically stop playing around now.

2) TEST AAF__file_colon_filename__.aaf --> links to file:TEST%20AAF.mxf
3) TEST AAF__file_colon_3slashes_filename__.aaf --> links to file:///TEST%20AAF.mxf

You might need to rename to aaf playaround files to exactly the aaf filename that you uploaded before.

Also, it would be nice to know your answer on @momocampo question if u dont mind

Ops ! sorry Momocampo I totally loose your question, so UME work like the MXF media files folder, when a new file is moved in the UME folder, Avid scan the UME folder and create on it the two database file, msmFMID.pmr and msmMMOB.mdb, so basically now is possible to edit directly an xdcam mxf op1a or an apple pro res mov, like as an Op-atom file, and like as the op-atom file is not possible to link via AMA a file in the MXF folder (or in this case UME folder), the only way to import it on your bin is to use Media tool, or import the .mdb file present on your UME media folder on your bin, I don't like this workflow because when you have a lot of files in the media folder, to use media tool or to import .mdb is no more convenient, in my opinion a possible functional solution is to create a workflow that move OP1a file in the UME folder and create an aaf link to this file, to simple find it, the same workflow that I use for the classic OP-atom files.
