24p is just the filmic frame rate. It gives a different temporaral feel. But your videos still look very video. The colors, for example, are a dead give-away. There are many other differences between film and video besides 24p.

Looks the same, almost. It's hard to tell the difference with web compressed files. The program was very flatly lighted which would give film a video look!

yeah, I think the 24p thing is the last little (very little) piece in a very large puzzle. More of the filmlook happens in front and behind the camera than inside it.

Most importantly, how is your audience going to view your piece? On a 35mm film out? 24p will be much easier to transfer. On a monitor/DVD? they run at 60i, so 30p will look better there. You'll have to add pulldown to convert to 30p later anyway if you're not going to film out with it. Many transfer houses actually have their transfers setup for 60i too, so that all depends on how your film printing company wants the footage.

If you're specifically looking to increase the motion trails to give a more dreamy quality, then the shutter speed is the thing that does this part...the 24p is just a nice round number ( half ) when you're using a 1/48th second (180 degree) shutter. Due to the nature of digital, you can technically now fit a 1/48th second timeslice into a 1/30th second frame...you can do that and not worry about converting for distribution.

"Better" is really an artistic concern . . . 24 fps movies shown on 60i TV look just fine, and as 24p on 60i TV employs the same pulldown scheme, the motion is exactly the same as 24 fps film. Now, if you want a smoother motion cadence, then 30p might be what you want -- but it will be different from 24 fps film.

Hollywood movies are all laid to DVD as 24p files -- shown on a 60i television, the DVD player adds pulldown to make it 60i for display. Using 24p video, you can make a 24p DVD and it will behave the same.

If you're planning to go to film, the last thing you want is 30p, because 30p makes for a lousy conversion -- there just aren't enough motion samples to make a smooth conversion to 24 fps.
