Time Code Frame count jumping 2 to 3 frames in FCP
I shot footage at 720 24pn. I import into FCP and step through the frames and FCP jumps up the time code two to three frames every frame advance. In other words the time code count jumps however FCP steps to the next frame. The camera is set to free run TC.

What’s the highest frame number that it goes to? Is it somewhere around 59?

Yes

That’s the timecode based on 59.94 with the 3:2 pulldown removed.

So the camera does not do accurate 24 timecode. That does not seem possible!

You have to understand how this all works. If you have ever shot with a Varicam, you know that the Varicam records at 60p always, no matter what. When shooting in 24p mode 3:2 pulldown is added to get the frame rate up to 60fps to get it down to DVCPRo HD tape. You can then remove these redundant frames upon capture. the HVX is similar in it’s operation, EXCEPT it records only the 24 frames, but it’s still based on 60p material. The fix?
If you control click on the the top line of your browser where all the columns are listed (name, vid rate, compressor, etc.) you should see a drop down menu. Select “Show tc rate” then a tc rate column will pop up in your browser. When it does you will see that it says 60. Change that to 24 by control clicking and selecting 24. You can select many clips like this and change them all at once. You will get a warning saying that it will modify the file on disk, and you choose whether to accept or not.
What do you need the tc for anyway?

I am locking three cameras for a multi camera shoot. At the beginning of the day I was going to shoot a tc slate set at 23.98 and calculate an offset. But if the timecode constantly jumps when I step through the frame in FCP I can not get an accurate offset. Dp you think your tip will solve my problem.

Try it, you can always change the tc back to 60 if you want.

Unfortunately the time jumps from the original time code on the clip.

I understand, if you do my tip, it won’t. The timecode will be 24fps consecutive. If it doesn’t work you can change it back to the original 60p based timecode.

Hi,
If you are shooting in 24PN, the camera is recording only 24 frame time code, I just looked. Take a look at how you set up the sequence, it needs to be set to DVCPRO HD 720P 23.98. If the capture is set to 60 and the sequence set to 23.98 you will find that it will have screws loose TC.
Hope that helps,
Jan
