Reversing a Conform 25 to 24
Hello All,
Is there a way to reverse the processing of 25fps PAL clips that the Conform 25 to 24 Tool was used on?
Our telecine facility was supposed to run the telecine at 25 fps, instead they thought it was best to add the duplicate frame. This naturally has messed up our workflow and most importantly our Neg Cut Lists. The project has been cut by the Director and naturally I get the call when the cut list is wrong. Any thoughts on righting this ship, I’d hate for him to have to write this cut list out by hand….
My thoughts were to reverse the conform process, so that the sequence is back to 25fps and then run it back through Cinema tools. I figure that way the Timecode/Keycode relationship in the database will be corrected and we can arrive at an accurate cut list….. any thoughts???
Thanks

I found out that there is no way in FCP or Cinema Tools to “Undo” the conform. Since the timebase of the original file is the only thing that has been changed, does anyone know if there is a utility out there that you can run on your files to reset the timebase back to 25fps?

Can you give a little more information?
What frame rate was the film shot? 24?
Was the telecine done at 24 + 1 to get 25 PAL, instead of frame to frame?
What settings did you use when you set up the Cinema Tools database, especially what were the Video TC Rate and the TK (telecine) speed?
What timebase are your sequences? Are you editing at 24 fps PAL?
Do you have the ability to recapture the original tapes?

in cinema tools you can conform any clip to any (useful) frame rate.
open cinema tools and goto file->batch conform. select any clip from the folder where the clips are and choose the desired frame rate.in this way you can conform your clips from 24 to 25 which may (or may not) solve your problem. if anything goes wrong you can reverse the process.
note: i think the command “batch conform” is new to cinema tools version 3. if you have an older version you may have to do this clip by clip.

Hoping someone can help with this;
I shot some footage with a Canon 550D at 50fps. I want to edit in final cut so I used compressor to change it to Apple Pro Res 422.
I was then told it would work if i just conformed it to 25fps with cinema tools. I tried this with a batch of clips to see if it would look better. It looks fine but the footage plays in slow motion in FCP now. It’s also still a H264 codec which I understand is no good for editing.
I can’t find anyway to reverse the process?!
I could put the 25fps clips through compressor to change them to Apple Pro res, but then A. will I loose quality? and B I will still have to speed it up to 200% in FCP just so it plays back at normal speed, will that also reduce the quality?
Any help would be appreciated.
Cheers
