Capturing HD XDCAM 720/24 over 60 to 24p timeline

[Shane Ross]

There we go…yeah. I have a boatload of HDV footage shot with the HV20 intermixed with DVCPRO HD 720p 23.98. The HDV footage is 29.97…you cannot capture it as 23.98 via a Kona or MXO (no flags), and you cannot use Cinema Tools on it as it cannot Rev Telecine GOP formats.

BUT…i was able to use compressor to convert to DVCPRO HD and 23.98 reverse telecine in one pass. You should try that.

and like I said before, if you need some preset help, I can get something for you to at least test it.

I am trying to test the reverse-tele (23.98p scan recorded at 60p, XDCAM HD422) using Compressor and the issue I am running into is that the frame rate remains 60p unless I change it in the encoder settings or the duration settings. If I change the encoder settings, I get a 23.98 file that imports into FCP, has 24 frame code and no motion issues and looks ok but aren’t I just shaving frames and NOT removing the pulldown? If I leave REVERSE TELE selected with no changes to the encoder rate or the duration the output file is 59.94p.

Also, since there is no 720/24 XD 422 encoder in Compressor/FCS I am choosing the 1080p24 XD422 encoder and manually changing the frame size to 1280 x 720.

Any thoughts?

In the encoder settings, you have to set the frame rate to 23.976 (not 23.98) after you have selected your codec.

Ok, but the question remains– should I be changing the actual encoder settings to begin with to affect the reverse-tele? Isn’t this just shaving off frames? I’m guessing that it does, though so far the converted files look ok.

[Ian Cook] “should I be changing the actual encoder settings to begin with to affect the reverse-tele?”

You need to tell the encoder what frame rate the movie needs to be, so in that case, it needs to be 23.976.

The reverse telecine operation should remove the appropriate frames, as it does with standard 3:2 pulldown interlaced material. Yes, it’s the removal (shaving) of the appropriate frames, just like any reverse telecine, to get your the real frames for 24p, sans pulldown.

Make more sense?
