DVCProHD capture 24p VariCam
Sorry for the newbie question, but essentially all my work in FCP with DVCPRO HD has been with P2 files. I’m capturing DVCPRO HD from Varicam tapes, shot at 24p (23.98 actually, i think). Most of the time the extra (duplicate) frames are not stripped at capture, even though the box is checked. Not starting capture until after the bars and tone at the head of the tape helps (I think thats hardwired at 60p & gets the capture confused) but even that doesn’t always ensure that the footage is saved as 24p.
Since I had to return the deck, I now have several files of 60p footage (24p with duplicate frames) and a few files of 24p footage. I want to work with a 24p timeline and end up with a 24p show. What’s the easiest workflow to bring my footage into the timeline at 24p?

Next time, use the DVCPRO HD 720p24 Easy Setup…that tells FCp to look for the 24p flags on the footage and remove the pulldown. If it still didn’t do it, then the footage might not have been flagged properly in the camera. It does have two 24p settings, one for the 24p look, but still running at 60fps, and one for 24fps with pulldown. I have that issue on a series I am working on. We are mainly shooting 720p24 at 23.98, but one DP didn’t shoot that way, they shot 24p, but the footage is 59.94, and just has the “film look.”
Try running the DVCPRO HD Frame Rate Converter from the TOOLS menu. Make sure REMOVE PULLDOWN is checked.

With DVCProHD is it best to capture via firewire when you are staying in that codec because it will removed those frames but via SDI it will not.
Try Tools > DVCProHD frame rate converter.
This should remove the extra frames but the files are not reduced like they are when it is done on capture.

You can capture to whatever codec you want AND remove VFR data with Kona cards and HDSDI, just for the record.

Sorry, but you are incorrect. I capture DVCPRO HD from tape via the HD SDI thru the Kona 3 all the time, and it removes the proper pulldown to get 23.98 files.

I guess I got stuck from the SD pull down removal days. Which I think is FW only but I could be wrong there also.

Robert,
One at a time, put a 59.94 clip into a 23.98 sequence. Make sure it plays ok, if FCP snags the wrong frame to start the pulldown removal process on it will playback looking jerky… If that happens adjust the in-point of the clip by a frame or two. Once it plays smoothly, export it as a self-contained clip. Import the resulting clip and whal-ah: You’ve got it the way you wanted it.
You can use the sequence settings to change the sequence’s time-code start time if you want to try and match up the original time-code, but 60 frame to 24 frame math can be tricky if you want it frame accurate.

Thanks Sam!
That’s exactly the kind of hint I was looking for. I did use the easy set-up for DCVProHD 24 capture, but still ended up with duplicate frames. I’ll try importing into the timeline and getting it to play smoothly. When I tried that before, the playback was mostly jerky garbage, like FCP couldn’t decode it properly in a 24p timeline, but I’ll play with various start frames.

Unfortunately, I just placed a clip in a 24p timeline and adjusted the start frame, step by step through about 10 frames and never could get it to play clean. It cycles clean/static at about 3 cycles per second. 10 frames should go through the entire 3:2:2:3 (or 3:2:3:2) sequence and get the right frame cued up at some point….
I also could not get the DVCPro Framerate Converter utility to work on these clips, I get errors stating: “An error occurred during processing. Unable to conform source media”.
I never got any dropped frame messages or any errors during capture and the clips play fine in Quicktime outside FCP or in a FCP 60p timeline. Stepping through them they are obviously 60 fps, but the image only moves every second or third frame…
What if I put the clip on a 60p timeline and output (export) a DVCProHD24 quicktime – will it re-encode and cause another generation of compression?

Opps = Looks like maybe I just need to render the clip to clean up the duplicates. Will take a while but I’ll give that a try…
