video at 23.98 Timecode at True 24
Okay, this is a crazy one. I have video at 23.98 and an audio LTC track at true 24 from a ProTools Session. In the end, I need a window burn of that true 24 frame timecode over the video. Problem is, when choosing the tc base in FCP, “24” actually equals 23.98. Is there a way to get FCP to burn-in true 24 frame timecode over a 23.98 clip or sequence? I can tell FCP what the beginning timecode is, all it needs to do is count it and display it as true 24. Thanks, Jason

You might have to try to create a new timeline and deliberately set its frame rate to 24.000, then re-nest the 23.98 fps sequence into it. Don’t let FCP try to override. Bon chance.

Just to make sure I am doing what you suggest (I am a little confused about “re-nest” so think I am missing something):
I create a sequence at 24 and insert the 23.98 clip. Deny FCP when it asks to change the sequence rate.If this process is correct, then it plays the 23.98 clip at 24 (speeds it up) and the timecode starts to drift.

you can’t get a 100% acurate printing because there are two different time-bases. Some frames TC will be repeated.
The first thing you need to get the TC of that Protool file, is to make a QT movie with a Video track (Black), so you can apply the TC Reader or Generator in FC.
Then you can lie that clip in top of your sequence, apply the TC filter and set the “Composite Mode: Multiply”.
The TC of the 24 clip will get burned on the 23,98 clip.

hmmm, this sounds interesting, but I am a little confused. Make a 24 frame QT file with the timecode of the ProTools session?

The video and audio are matched fine. Track 1: LTC, Track 2: camera mic. SO, Track 2 and the video are in sync. I bring them into FCP as 23.98. BUT, I need the window burn to match the original LTC timecode on Track 1 which needs to display and run at true 24.

Thanks, for your input…But, I am still interested to hear more specifics on Rafael’s solution.

Jason,
Sorry i have not replied earlier.You have stamped your file with the wrong framerate TC.
Kill the TC track and replace it with the correct one.FCPauxTC reader cannot see the difference between 23.976 and 24.
So you have to set it right in the setup menu.
(It will overwrite the current TC track)After that things should work out just fine.
hth,

This is not making any sense. Why are you working this way?

[Dave LaRonde] “Dude, you have a frame rate mismatch. “
Right.
The mismatching is unavoidable (23’98/24), but very small. Few frames will be skipped.[Jason Watkins] “hmmm, this sounds interesting, but I am a little confused. Make a 24 frame QT file with the timecode of the ProTools session?”
Don’t know nothing about Protools, but I guess that you can export that as any QT audio file (PCM, AIFF) KEEPING the TC.
You just need to put add a video track (Black) on FC or QT to get a plain 24fps QT movie (whatever the codec) with the original TC from ProTool.
You just need drop the clip in the sequence and apply the “TC Reader” filter on the clip.
In the Canvas you get a Black with the white TC burnt in.
Set the the clip to Multiply, to get the TC burnt on the underlaying picture.
Easy.
I understand that you don’t care about the audio of the 24fps clip, but about the TC.

Rafael,
The sound IS the TC in this case.
He’s using LTC on an audio track, and FCPauxTC reader to translate it into QT TC.Bouke
