24p vs 30p
 
If I am shooting a project that I absolutely for sure know will never be filmed out is there any reason I should shoot 24p instead of 30p? All other things being equal, is the asthetic differences between the two frame rates really that different?

The video I am shooting is just going to be a simple demo video that I will distribute on NTSC DVD and have available as a downloadable HD file from my website.

yes there is a big aesthetic difference between the two. 30 looks live.
On the other hand. 30P gives you better and smoother slow motion than 24P.

30p is still a bit too juddery for me to say it "looks live." You've at least got to go up to 50i/p before it starts looking live.

For the question at hand, I've never shot 24p or 30p so I don't really have an opinion.

For the record - which format do you shoot with Stephan? 25p?

For what it's worth, I don't notice a huge difference between the look of 24p and 30p, but I almost always choose 30p because my editor (Vegas 7) seems to like it better. 24p footage tends to slow Vegas down on my computer, whereas 30p footage edits as smoothly as standard DV.

60i/p. I don't deal with slower frame rates since I don't need them for what I shoot.

Cheers Stephan.

When stuff is going to the web 30p is ideal. There's no need to deinterlace and 15fps is a good web frame rate.

I think the difference is in the motion blur. 24p is cool for the 24p look and that's about it sept if your going to film. I use 24 for dramatic stuff since I like to look of it, but I use 30 for just about everything else. I must confess that seeing a 6fps difference takes better eyes than mine, unless there is motion or camera movement, and even then......Also I like 24 for Flash video, lower data rate. Personally I think faster frame rates don't look real, they look hyper-real and I prefer the flickery, juddery, blurry look of slower frame rates, I think they are closer to what I see.

It's odd isn't it, some folks refer to the higher frame video rates as 'live/realistic' other's say the same about 24/25p.
If you do a slow pan with your head in your office/studio/room etc (stay with me!) it resembles (to me at least) film. Interlaced video looks to me like...'television' a brash, artificial reality, but perhaps that's just me.
I only really have the option of 25p & 50i on this camera so unfortunately I cannot judge 30p.

You should be able to shoot 30p (720p30) on your GY-HD101E (or 100E).

On page 90 of the camera manual, it says,

"Video Recording format : 720/24p, 720/25p, 720/30p, 576/50p,
480/60p (GY-HD100U/HD100E/HD101E)".

You should be able to go into your menu system and change the frame rate to 30.

Sorry David I should've worded if differently...I 'can' shoot 30p but it's not option for me/us in pal land.
Intrigued with 50p mind you (routing around to see some footage on these boards). I know there are calls out there for me not to shoot 25p...there's the 1080i route (Sony Z1 for example) so 720p50 may be an option over 1080 50i.
Perhaps the HD200/250 is the way to go although at that price there may be other's on the market.
Thanks.

Sorry for bringing up an old topic, but I was wondering something. We recently bought a jvc hd111 (europe) and we have some different projects comming up, fon instance videoclips, where look-as-much-as-film is preferred a lot of times. So you would say that you want to shoot 24p.

But the end video will only be looked on tv's and internet, where it will play probably 25 frames a second.

Don't you loose the 24p effect if you play the footage i the end back on 25 f /s.? So how does this work?
