DVCPROHD 60fps frame repeats
Hi to anyone who can help me with this! I have some footage that I’m trying to work with that is behaving a little strangely, to me. I did not shoot or capture it, but I do have to work with it, so I’m trying to figure out what the heck is going on. FCP identifies the footage as DVPROHD 720p footage at 59.94fps. When I look at the footage, though, each frame appears for six frames in a row, making it an effective 10fps. Like this: AAAAAA BBBBBB CCCCCC DDDDDD EEEEEE FFFFFF etc. etc. I know nothing about how DVCPROHD works at 60fps, so maybe this is what it’s supposed to look like?
I know the footage was shot with the intention of getting a sort of edgy/fuzzy effect, but it still seems to me like there should be a new image in each frame. I ran a little of it through Compressor and turned it into DVCPROHD 720p 23.98fps, and it looks better on playback, but obviously since there are so many repeated frames in the original the pulldown still ran into a number of those, and there are quite a few repeats in the converted piece. (AAA BB CC DDD EE FFF GG HH…)
Any thoughts are welcome. I’m thoroughly confused, myself.
Thanks in advance for your help!

Sounds like your footage is under cranked for purposes of playing back the footage so it looks sped up.
What frame rate is your timeline?
Have you run it through the Panasonic Frame Rate Converter?

The timeline is 60fps. I have not run it through the Panasonic Frame Rate Converter – to be perfectly honest I don’t know what that is.
As far as I know, it was shot only to look a bit rough, not to look sped up.

Well, if you have that amount of pulldown, it wasn’t shot @ 60, it was shot @ 10 like you said. Try this. Open a new project and import ONE of the files to the root level of the project. Make sure it is selected in the browser and go to Tools > DVCPro HD Frame Rate Converter. Choose to conform to 59.94 and make the movie self contained. Reimport and play that new movie. What does it look like?

Yeah, I got there in the end, but it looks the same. The best looking result I’ve had so far is the 24fps conversion, but clearly I need to talk to the folks who shot it to figure out what to do with this stuff.
Thanks for your help!

Do you have files or did you capture this stuff? is it P2 based?
Try conforming the file to 23.98 instead of 59.94. See what happens then.

As you have said that you did not shoot nor capture it, and that “I know the footage was shot with the intention of getting a sort of edgy/fuzzy effect,” I suspect that the shooter purposely shot at a slower shutter speed NOT for purposes of undercranking, but for the soft dreamy look of shooting at, say, 1/5 second. This effect, usually found on consumer cameras as a way to effectively yield a higher gain in low light situations, will indeed put that same image on adjacent frames. If the subject seems blurry due to either subject or camera movement, then my money is on this as a shooting style.
How do “fix it?” Don’t. It’s the camera-person’s vision.
just a thought.

Geoffrey, great call. We call it streaky cam.
Steve, any chance you can post a second or two of this footage?

Thanks to everyone who’s offered their thoughts and I appreciate all the input. I did finally get a chance to talk to the original shooter and it was a creative decision on that end (the footage was not shot for this project originally). I’ll see what I can do with it, keeping in mind the soft look they were going for, and hopefully come up with something good.
