24P with Compressor 3

[Austin Meyers]

I capture in fcp 6, and the select everything and "export using compressor" once in compressor I apply either a prores codec or an hdv codec with "reverse telecine" turned on in the frame controls ( if you have remove pulldown turned on you don't have to mess with the frame rate, just leave it on current).

I then set the destination and submit the batch... Once its finished batching i drag all the newly created project, delete the old ones out of the project and delete the source files as well.

Although square pixels are nice, I think it's best to keep the 24p footage at 1440x1080 - and don't be tempted to rescale it to 1920x1080. (at least not in Compressor).

It looks like Compressor does an amazingly bad job with any scaling. Not just bad, but bizarrely inexplicably bad.

Scaling results in very visible scaling artefacts. The visible blocks, which look like pixels, are in fact 4x4 pixel blocks.

I think this might be the same problem that was manifested in the thumbnails earlier in this thread.

The image on the left is the the output from Compressor without scaling. So it is a 1440x1080 image. It is being scaled back to the correct aspect ratio using the settings in Quicktime.

The image on the right is using identical settings but allowing Compressor to scale up the output to 1920x1080 square pixels.

yeah i like to keep everything native rez. especially if i'm exporting back to hdv 24p because then it intercuts natively with the other canon prosumer hd cams that shoot native 24p.
