24p or 24pA

Hugh Mobley · April 23rd, 2007, 05:58 PM

I need to get this straight, if I am reading this correct, If I film at 24p I capture clips with the following properties: I am using HDV 1080 24 p (1440x1080, 23.976 fps template. frame rate 23.976 (IVTC film), edit and render maybe at HDV 1080-24p intermediate avi or which?? If I shoot at 60i the I would change the properties according, David, I have listened to your 24p tutorial and I think I gathered that when one uses Vegas and the film is shot at 24p, Vegas automatically corrects when it goes on the timeline. When using 24p should the properties be set a particular way?

What camera are you shooting with?

My tutorial was for the 24p DV cameras which shoot 24p, but pulldown removal works for SOME of the HDV cameras . . . but not all. Each company uses its own flavor(s) of HDV and implements 24p (or 24F) differently. It's not all compatible with each other, so which camera you used matters.

David, its a HVR-V1, I use 24p most of the time, but have noticed on some shots where I am panning there is motion blur so I thought I probably use 60i or at least up the shutter speed. In fact the 24p is one the reasons I went from a HVR-A1 to the V1., thanks

I have not actually had my hands on/worked with any unprocessed V1 footage, but according to Spot, Vegas 7 removes pulldown automatically from V1 footage.

Check the clip properties in the Media Pool. (You know, right-click, choose "Properties.") Check the Stream properties.

Your timeline template is fine, though (as long as the PAR is 1.333). As for rendering, that's a matter of your intended purpose.

As for the motion blur, there could be number of factors involved in that, including, as you say, shutter speed, but also speed of your pan, HDV compression, etc.. In general, when you shoot 24p, don't shoot like it's 60i -- move the camera slowly. The motion characteristics between the two aren't the same, so things which look fine in 60i may not in 24p.

As I said elsewhere, to mimic a film camera's shutter, use 1/48 or as close as you can get.

I'm trying that replacement method. Seems to be working so far. . .I just hope it doesn't move some/all edits over by a frame or something.

There's a 10% chance that any one edit point may now be on a mix frame. But the worst anything could be off is by 1 field.
