HD frame rate converter question

[Walter Biscardi]

Move the footage to be changed to its own project and try the tool there.

If that doesn’t work, recapture one clip using the DVCPro HD 720/60 preset (Firewire capture) and try the tool again.

Walter, I’ve tried your suggestions. Mostly just creating a new project and importing the clip to see if it would the work. Unfortunately it didn’t. And, unfortunately, I’m using the old 130 HD deck which does not have the firewire out, just the HDSDI, so I can’t use the other DVCPro HD 720/60 firewire preset. Somehow I think that would work too! Guess I’m stuck with Kona. Any other thoughts?

You shot it with the Varicam at 10fps? Then it isn’t the required 59.94 format that FCP requires to do the conversion. Even if you captured it using the 720p60 easy setup, FCP knows that it was shot at 10fps.

Ok now I’m getting confused. First, my goal was to shoot a time lapse sequence. It was recommended that I shoot at 6fps at an interval of 10 frames every 2 seconds to get a nice sunset time lapse. I was also under the impression that I could then use the frame rate converter to smooth the time lapse footage out. Beyond that, I had no idea how it all workedout until I actually brought the footage in to FCP and used the converter. With these assumptions apparently wrong, how should I have done it?

[Johnw3d]

Are you trying to achieve conventional time-lapse so that when you play the video, time speeds up and you see clouds and sunsets whizzing by? If so, what you need to do is conform the footage to your desired output video frame rate. If you shot at 6fps and conform it to 30fps, it will speed up time by a factor of 30/6 = 5, and whiz goes the sun. Unfortunately, FCP doesn’t have a general-purpose conformer (just 25 to 24), but After Effects does in its Interpret Footage dialog, so I recommend using it.

3 things here,

1) material that will be run thru the FRC needs to be in it’s own project OR be at the root level of the browser, not in any bin’s or sub folders.

2) DO NOT USE “CAPTURE NOW” or capture Bars and Tone for VFR material- both of these have issues with the software FRC.

3) why not use the 720p 23.98 Varicam settings and have the kona card do this for you.

Interesting Gary and excellent advice. I am aware of needing to transfer the clip to a new project in order for FRC to work. But what’s interesting about your recommendation is the fact that I did have to use capture now because I kept getting dropped frame erros on batch capture. I just assumed it had something to do with the time lapse recording creating broken time code. So I’ll do a batch capture with the “abort when detecting time code break” off and see what happens. But I really like your idea of simply using the 23.98 setting. Go figure!

[Alan] ” the fact that I did have to use capture now because I kept getting dropped frame erros on batch capture.”

It is actually the changes in the cadence of the pulldown. when you go from 23.98 with the standard 3:2 pulldown to 10 fps with it’s 10:1 pulldown the capture is not smart enough to compensate for the break in the timing. The Kona cards however do not use the FCP timing but only the flags – but you have to set a hard in and out point or the software cannot compute the point to begin and end correctly so that it only captures the flagged frames

[Alan] “So I’ll do a batch capture with the “abort when detecting time code break” off and see what happens. But I really like your idea of simply using the 23.98 setting. Go figure!”

yeah the kona cards really blow me away with this feature I know many people that are using them to capture 10bit UC footage straight from the cameras
