24p choppy

I just got my DVX 100a, and I have a few questions. i've shot some test footage on 24p, 30p, and 60i. When I watch the footage on the VCR mode, the 24p looks way too choppy, and almost reminds me of cell phone cameras. 30p, looks much better, and 60i just looks like video. I've seen tons of threads about this, but none of them have helped me. If I want simple movements in my camera, and I use 24p, what should I use for my fast action shots?

I am NOT editing the videos yet, I'm simply trying to get a nice look to my shots. It has nothing to do with my shutter speeds either.

Why is it that movies look so much more fluid than the choppiness of the 24p on my camera?

I prefer the look of 30p, so far, but I've heard it's hard to work with using Vegas, which is what I'll be getting.
 
Were you shooting 24p or 24pA? 24pA is usually what you want to shoot with, but it will look strange when played back directly from tape. 24p will look smoother directly from the camera, but it's not as nice for 24p editing.

Something to consider about 24p and judder/studder: Film shot at 24p generally has much shallower depth of field than video. Usually, only the subject is in focus and the background is out of focus. Thus, judder is not as apparanet. With DV, you have deeper depth of field, so everything starts to judder. You have to exert some effort to achieve shallower depth of field on DV to reduce judder as much as you can.

Also, you can get away with moving camerawork and action camerawork, but it's important to have a skilled operator who can steadily track the actor(s). It's not so important how fast the action is moving, but if the operator can keep the actor in the same relative spot on the screen. As long as the actor stays in one place and the background moves, most viewers won't notice the juddering backgrounds.
 
what about for random shots, for example, a shot of houses going by as you drive by with a camera. Any tips with simple panning of the camera to reduce the judder?
Also, I'll be editing my stuff on Vegas. Is there a way to use the same timeline to edit shots done in 24p as well as 60i? So that I can do most shots at 24, and HEAVY action stuff at 60?

Thanks for the help by the way.

Something else, does anyone know what Collateral was shot at (60i or what)?
 
so you just got the DVX, and the questions you are asking is really baisc stuff.
it's all explained in Berry's books so you might want to take a look at his book if you think you'll be serious about learning the DVX.

anyway, in the book it said that 24p isn't enough frames to shoot fast motion so you have to be carefull when ever you pan.
that's way when you change the settings to 24p and pan the camera around you'll see the glitchy movement in the viewfinder and say "Hey the 24p doesn't look good at all"
so you would have to be carefull when ever you shoot handheld in 24p.
also if you want to pan, there is a chart how fast you can pan the camera but it's all in the book

if you want to edite 24p and 60i on the same timeline just shoot 24p and 60i. do NOT shoot 24pa.
 
I'm low on cash right now (seeing as how I spent $1400), so I can't get the book just yet. Until then, I can use the help of the people on this forum. Definately want to get the book, though.
 
yeah you can get the book when you have the chance.

if you are shooting these type of scenes I would just shoot in 60i.
but if you want to shoot in 24p, you can increase the shutter speend and it should look better.
 
what you could always do is shoot those shots in 30p and then just shoot the rest in 24p so they fit in the same timeline. the viewers won't notice the difference
 
If you don't like 24p, don't use it. It takes some getting used to, and it's usually the right choice for narrative filmmaking. I really wouldn't recommend mixing frame rates, because it's a pain in the butt and it reduces the outlets you'll have to promote your video. Good luck getting a film that mixes frame rates to project properly at a film festival. Most can barely get 24p stuff projected correctly.

My hunch is that the more you use 24p, the more you'll get used to it, and in a week or two, it won't bother you at all.

Yes he is right, I should have though of that before... I was just reading an article about all of that that I will link at the bottom. If you want to shoot in 24p, definitely go for 24pA. That is if you're only going to use it the whole project. If there is going to be mixed frame rates, you have to shoot 24p. Here is the link to the forum I was talking about:
