Problem with 50p Canon 5D MArk lll footage
on Dec 29, 2013 at 10:16:33 am

We shot on a Mark lll in 720p with 50fps and now we would like top import the material to AVID 6.5.
When we link it to AMA files, then the material is seen in the right way and we have the option to promote it in the TimeWarp.
But when we try to import or transcode the AMA files then this connection is lost and there is no more option to promote and it sees the clips as 25p.
Any idea, why this is happening?

You can only have 50p in a 720 project in Avid. If you are in a 1080 project, you can only convert to 25p. There is no 50p option at all.

But we are in a 720p project.

An import or transcode of any material that does not match the project frame rate and raster type (progressive/interlace) will create media that is now that project type. For example, 1080i/59.94 material in a 23.976p project will become 23.976p material via motion adapters and the timecode becomes 23.976, losing the original 30NDF or 30DF timecode of the source. For some workflows, that is fine, for others it may not be. If you do need to go back to camera originals in an offline/online workflow then give my bog a read on how one can do that:

I am assuming you are seeing the motion adapter because you are in a 720p/25 project and you now have the ability to change the motion adapter to 100% creating a slomo. If you were in a 720p/50, the file would already be at the proper rate and no motion adapter applied.

So depending on what you want to end up with, you can start in a 720p/50 project, transcode there, then open that bin in your 720p/25 project and you will now have the motion adapter available at your target codec choice.

The problem now is, that the export (720p DNX 60) looks terrible lots of artifacts and digital noise, way more than the camera original files.
Can this come from the workflow you described above?
I am about to rebuild the whole edit in X.

Thanx a lot.
