Breaking down 24p Barney style
Hi there. I just started working with some brand new equipment – Canon xl-2 and Final cut pro HD 4.5. I’m interested in learning the correct procedure to get great 24p images. My final output will be DVD. How does FCP interpret the images? What do I need to do to lay them off to dvd – does it need to be encoded differently to be viewed on an NTSC monitor? I’ll probably be mastering in DVD studio pro, which I am also just learning. Will the obnoxious ‘stuttered’ look that I see in the xl-2 viewfinder be removed in FCP? Questions, questions! If anybody has any insight or any web resources i can surf to, please let me know!

This article references the dvx100 and not the Canon, but there should be some useful info for you here.

Everything in the article applies to the Canon as much as the Panasonic, but Canon tent to name things a little differently – that’s all. The workflows are the same.

Wny do you want 24p when you are ending up on DVD?

I guess i don’t really want 24p on dvd, I need to convert it to 29.97. That’s why i’m asking all these questions!

Shoot 16:9, 30p (I’m from PAL land) and slighly underexpose. Once you’ve clipped the whites they are gone forever.
I’ve just finished grading a short film that wa shot on a XL2 using the above and I was impressed by the quality.

[Todd VanSlyck] “Will the obnoxious ‘stuttered’ look that I see in the xl-2 viewfinder be removed in FCP?”
As far as I’ve been able to find out, the stuttering ‘in-camera’ look you’re referring to is due to the short delays while the audio is being synced to the video, and will not be present in the final project. Since I haven’t had the need to shoot in 24p with my XL2 yet, I’m just going on the info I’ve been able to find out so far.

Hi Todd,
I totally concur with Peter. I absolutely HATE the stuttered look of the 24p that comes out of my DVX100. But the 30p is gorgeous. I use an anamorphic converter lens and it just looks great. Add to that the 30p film look with Gfilm and I’m a happy camper.
Peter, OUCH! you had to put in that little jab about being in Paris!!! Major envy.

24p is one of the supported DVD frame rates. All Hollywood movies are encoded this way, with 24 unique frames per second, rather than the 30 that NTSC normally uses. This gives a great advantage in picture quality as more of the avaliable bit rate can be used on the fewer frames, rather than wastefully encoding the 3:2 pulldown pattern as used to bring 24p into NTSC.

You can put 24p on DVD just fine, and indeed, it will look better than 24p converted to 29.97fps by using 3:2 pulldown.

Don,
I’ve done a bunch of tests with MOS 24p footage and it all stutters like crazy every time something moves. Nothing to do with audio there.
