Think it's ok to record 720/60p, even if I'm distributing 24p?

Hey,

I've been thinking about this a lot. What are the disadvantages to recording in 60p instead of 24p? More compression?

Even if I'm going to distribute in 24p (or even 60i for SD-DVD), it seems to me like the more information I can record, the better. This also gives me the option to go slow-mo for any surprise action shots.

I guess what I'm really asking, is if there is a technical reason that "native" 24p would look better than 60p converted to 24p. I don't understand the 2:3:3:2 and 3:2 pulldown methods and am still looking for a good reference on those.

I would also try it myself, but my computer doesn't playback footage smoothly all of the time anyway, and I wouldn't trust my eye just yet to catch little details I might be missing.

So what do you think? As long as I don't need the added resolution of 1080, is there any reason not to leave the camera in 720/60p all the time?

Thanks

I'm not 100% sure, but 24 doesn't divide evenly into 60, so wouldn't there be a few frames lost in the downconversion?

that logic sounds sound, but even so, you're recording so many 'extra' frames that losing a few here and there at 24fps shouldn't even be noticeable.

i'm wondering the same thing myself (shoot 60p all the time), but i think that the real difference between shooting 60p and playing back in 24p timeline vs shooting 24p is in the image itself. i could be wrong, but seems to me that shooting 24p will give you some motion blur whereas 60p in 24p will not.

and that is one of the desired effects of 24p, that soft look. i think 60p in 24p would look much more crisp and quite possibly the staccato skipping effect of 24fps would look much more harsh and annoying. whereas the gaps between frames in 24p motion are blurred and smoothed out.

For one your shutter speeds are different giving a little different look. In 24p your at 1/48 (most common and at 180 degree) and in 60p your at 1/120 (in 180 degree) you can set it at 1/60th in 60p but it still is fater than the 1/48th. If you start the movie in 60p 1/60 or 1/120 and don't cut to footage your trying to match with 24p 1/48 shutter I doubt very few people will know. It'll have a little dfferent look but thats ok in my opinnion, maybe it will make t look better for your content.

Oh yes, it's noticeable for sure.

The only thing which will cause motion blur is a slower shutter.
