I am a postproduction supervisor trying to help out our picture editor ;-)
For our 25fps-project the post house exported 25fps-MXF-files for the mixing stage. As we will produce a Dolby MOD with 24fps, I have to convert the MXF-files from 25fps to 24fps. As the imgae in the mixing stage is played back from an AVID MC5 (or 6?) I would like to adapt the files in MC. I googled a little bit and my questions are:
- Is one way of achieving this to import the 25fps-MXF-files into a 24fps project and correct the speed of the clips in the timeline from 104% to 100%?
- Is it necessary to render afterwards? playback seems to be fine without...
- Will changing the speed affect sync issues i.e. edits not being exactly where they should be, varying sync, e.g.
- I need to make sure that this method is 100% correct, as we won't have a 24fps-print to check sync when recording the Dolby MOD.
If Mix and Match kicked in, there will be a green dot on every event. You can open those motion effect adaptors and change it back to 100% rather than 104% (no batch process for doing so).
You could always treat the sequence as an output to tape via a QTrefence out then back into the 24p project rate and setting "ignoreqtrate true" in the console. This will cause a frame for frame import resulting in a 24fps slow version of the 25fps media. The same can be done via AMA by typing 'SetAMAQTForcedFrameRate true 24.000' into the Console before AMA-linking. 'SetAMAQTForcedFrameRate false' turns it off in the same session. I don't believe the command persists when shutting down and coming back in.
