Reverse Telecine Woes In Cinema Tools

[Jeremy Garchow]

Do you have burn in tc? You have to choose the A frame in Cinema Tools (park the playhead on the A Frame) and then perform the rev telecine.

Another problem…
The files that I got from the digibeta capture were too large for cinema tools to handle and so I had to break them up into smaller files so I cannot work from A. Im a bit confused by all of the options in cinema tools and I have tried several options but it all comes up the same weird interlaced look. I tried contacting the lab that did the reversal and they were really no help

Graeme Nattress has a free plug in to detect cadence at this location:

Here’s some instructions I got somewhere:

Nattress plug in to detect cadence:

CT makes you do a lot of hard work. It’s not automagic. You have to tell it the correct starting frame for the pulldown sequence. You can find a free plugin on my site to help with this. You use it in FCP, with the 29.97 footage on a 29.97 timeline, view 100% square pixels turned off so you can see the interlacing. Park on a frame with pretty obvious interlacing, and hit the auto button and it tells you how much to move the offset. Move around a few frames so that you can see if the whole and split frame sequence in the display matches you video. If so, go back to the first frame and read off AA BB etc. and that’s what you enter into CT.

Thanks for this but Im pretty much a novice and some of this does confuse me so I hope you will bear with me if I ask some stupid questions.

1. “hit the auto button and it tells you how much to move the offset.” -IN THIS CASE WHAT IS MEANT BY “THE OFFSET”

2. “Move around a few frames so that you can see if the whole and split frame sequence in the display matches you video. If so, go back to the first frame and read off AA BB et” -WHAT IS MEANT BY SPLIT FRAME SEQUENCE? I have not downloaded the plugin yet, is this a feature on the plugin?

3. “and that’s what you enter into CT” WHERE WOULD I ENTER THIS IN CT? it seems as though there is only a few options for setting in CT how can you actually enter something into CT?

Thanks

When film is transferred to video, the process is done by fields. A field is one half of the interlaced video frame. Interlaced means the odd number lines, and the even number lines of each video image are scanned separately onto the display.

So the first frame of film creates 2 fields, the second frame of film creates 3 fields (1 and 1/2 frames). 12 of the film frames (every other one) created 2 fields, and 12 of the film frames (the opposite every other one) created 3 fields. That is 24 fields and 36 fields, which equals 60 fields, which is 30 frames of video. Film has been transferred to video, although some of those video frames contain information from 2 film frames. That’s what you want to remove with reverse telecine.

You should read the Cinema Tools User’s manual. You can’t expect yourself to know what’s going on if you’ve never done it before. But on the other hand, you have resources that you haven’t used yet. Online discussions are fine, but reading source material is more efficient.

As for where in Cinema Tools you place the results of your exploration with the Cadence plug in:

Page 57 of the Cinema Tools User Manual “To open the Reverse Telecine dialog, do one of the following”

Thanks steve,
I understand the basic compositioning of the film to video process but what I am not following is your instructional terminology. For example you mentioned to input your findings from the cadence plug-in into cinema tools but there is no where to actually enter those into the dialogue, they are simply push button options. Also in terms of interpreting the findings of the plug-in I had a few questions on my last email that I will not find in the FCP or Cinema tools manual it is more a matter of clarifying your instructions…

1. “hit the auto button and it tells you how much to move the offset.” -IN THIS CASE WHAT IS MEANT BY “THE OFFSET” I don’t understand your terminology here what is the offset? where is the auto button? I have installed the plug-in turned off square frames and have the canvas at 100% but when I scrub through it I just get a code like wwwSWWAA or DD? How do I interpret this into something useful that I can use in the reverse telecine dialogue box in Cinema Tools?

2. “Move around a few frames so that you can see if the whole and split frame sequence in the display matches you video. If so, go back to the first frame and read off AA BB et” -WHAT IS MEANT BY SPLIT FRAME SEQUENCE?
Again your I am ignorant of the terminology. What is the whole sequence? the canvas? the viewer? the clip? What is the split frame sequence? the canvas? the viewer? the clip? What is “your video”? the canvas? the viewer? the clip?

Thanks

Those instructions for the plugin weren’t mine, I just had saved them on my system.

Here’s another post on the subject that might help.

Ask Telecine to provide you with a Telecine Log. I have not heard of not getting a FLX file or the like with your tapes. With a log, you get clips that begin on the A Frame and you merely just batch capture them. Without that, I’d not attempt to do any film project in any NLE. Can’t they provide you that?

Thanks those instructions helped!
I am now interlace free!!!!
Can’t thank you enough…
