Cinema Tools 3.0.2 pulldown removal is shortening my clip by 25%
Hi Folks
I’m a long-time Cinema Tools (aka FilmLogic) user so this isn’t a newbie question…I have a 10 bit uncompressed clip captured from a DigiBeta deck. Trying to remove the pulldown with FCP 5.0.2’s CinemaTools takes a 2hr clip and turns it into a 1.5hr clip!
Things look OK for the first ~5min but then it starts removing one too many frames, resulting in this jumpy, sped-up look. Looks like I shot it at 18fps!
When I try the same thing on FCP 4.5HD’s CinemaTools it DOES NOT change the length of the clip.
I have an additional problem in that the pulldown (which starts off looking like AABBBCCDDD) ends up looking like AABBCDDD – note that the C frame is still interlaced. This is true for both FCP 4 and 5 versions of CinemaTools. Yow!
I’ve tried excerpting a small section of the film – the academy leader to be specific – and reversing that. I get the funny BC frame no matter what settings I use in Cinema Tools – and yes, I tried them all!
When I made the small clip I made sure that the TC was 0 at an A frame (the START frame of the leader) so A frames should exist at 0 and 5 frame TCs. I verified this by eye in the Cinema Tools clip viewer.
Can anybody shed some light on either or both problems?
One extra piece of info – during the telecine session we stopped and restarted the digibeta deck in order to change film reels. So there’s likely a cadence break half-way through the clip. I know that I really need to cut the clip in two in order to get a proper reverse tele but I doubt this explains either problem I’ve encountered – or if it does it sure seems like it’s exposing a bug in Cinema Tools 3.0.2 rather than a “feature” or “limitation” of the software.

Your clip is probably too long for CT to handle.
When performing reverse telecine to remove pull-down, avoid using large files wherever possible. In some cases, large files may result in issues with timing and audio sync. For the best results, use files that are under 2.5 GB for reverse telecine.
If you have larger files, you should split them or recapture them as smaller files before performing reverse telecine.

If the clip was shot in 24p the pulldown removal can be made by compressor. If it was shot in 24p advanced the pulldown probably won’t work and it needs to be recaptured letting FCP do the pulldown removal.

Cinema Tools 3 is a joke. Every single time I need CT for a reverse telecine, CT 3 gives me problems. I too use a Blackmagic. Basically, I’d select the proper cadence for a pulldown, and after about a minute into the clip, it started getting it all wrong.
I keep CT 2.2 in my documents folder, and it always works perfectly. And I have no problems having both versions on the same computer at the same time.
I had a lengthy back-and-forth email conversation with someone from Apple’s CT team. Nothing really came of it. It got to a point where she wanted me to send in my media on a FW drive. I just didn’t have the time. Later, when the 3.02 update came out, I thought it was all fixed. It wasn’t.
I don’t work with actual film, so whatever features are new in version 3, they don’t apply to me. I just need it for reverse telecine.
