Re: [Avid-L2] 35MM transfer to HDCam 29.97Psf Blended Yucky Frame?

 

Yeah, this sounds totally botched.  So I can suggest two options depending on what has happened in the transfer.  


The first is the obvious; they have to redo it because they did it wrong and didn't provide the service that was paid for.  In that event you can do a transfer to a MOV file and use either 2:3 or 2:2:2:4.  Or you can go to DPX-10bit or TIFF-16it and just do 1:1 and process that to whatever speed you want later.

Or

If your 5th frame that is crappy is a blend of frame 4 and frame 6 and to get what you need you just have to remove every 5th frame, then convert the MOV that they provided to DPX-10bit or TIFF-16bit and then use a line command to remove all the evil frames.  It would be something like

rm *.####[49].*

or 

rm *.####[16].*

it all depends on which frames are the bad frames.  But it should be consistent.  Like each 0 frame and each 5 frame, or each 1 frame and each 6 frame.

Once the bad frames are removed you can then process the remaining frames to whatever speed you need.

I definitely don't have more telecine chops than you, but can tell you that unequivocally this transfer was botched. If you transfer 35mm film to HDCAM, there is almost never a reason to do it any other way than slightly slowed to 23.976 and recorded on tape that way. Done. No frames are harmed in the process. Even if film was shot at higher speed, it should still be transferred to tape at 23.976 or 24. Someone either specified an incorrect transfer or goofed in making the transfer. I can't see any other way about it.

Working on a project where they had a 35MM print transfered to HDCam as 29.97 Psf.  Upon inspection the footage on tape is 4 good clean progressive frames then on split blended merged yucky frame.  On the bad frame both Psf fields are blended.  I'm curious how this cadence of error every 5th frame happens.  I'm told this was a 35MM to HDCam transfer.  From that I would expect it to have 2:3 pulldown or if it was requested that it be transferred to 29.97P it should have a 2:2:2:4 cadence.  The every 5th frame bad frame is a blend of the preceeding and following clean frames.  How can this be considered an acceptable way to transfer a film print?  I'm use to strange things on stock footage that was poorly reprocessed into progressive from who knows what but this is a brand spanking new film transfer.  Can someone with more telecine chops explain to me what they did in transfer land?
