New GH1 Owner, Pulldown Question

I searched the forums and couldnt find the answer so please dont flame me. Do all recording modes of the GH1 show pulldown or is it just a 24p issue?
 
Ok, if hat is true, why does In log and transfer, the couple clips I thought that I had captured in 24p show up as 1080i60?
 
The only 24p mode on the GH1 is the 1080 mode, and it's wrapped in the 1080i60 wrapper and must have the pulldown removed to get 1080p 24p, there are no other 24p modes on the GH1, so if you're shooting 24p mode, it's always 1080 in a 60fps wrapper...

There's 720p in 60fps (no pulldown needed) and 720p in 30fps in motion jpeg (no pulldown needed).
 
That explains it. Why is so much talk about pulldown removal on the Gh1 when I thought 720p was the "sweetspot" for the camera and you have to jump through hoops to get the 1080 material to work properly? Is the general consensus that the 1080 material looks better?

Thanks for the responses...
 
1080p does look more detailed than the 720 stuff. The image quality is better with 1080p, however, it's not without some limitations, you've got to plan your shots so that you stay within bounds of what the codec can handle, and as long as you do that, you'll get really great looking stuff.

720 mode is a bit easier, it's not as detailed as 1080, but the codec holds up better amidst rougher shooting conditions in terms of fast moving action, etc., quick pans, etc., so there are tradeoffs to both the 1080 and 720 modes, you really just have to pick the right mode for the job and the planned destination format. If you're shooting stuff that is only going out on the web, 720 is great, however, if you're doing a narrative that may end up on the big screen, you want the added resolution of 1080 plus the 24p framerate.

You really don't have to jump through hoops for 1080p, people make it out to be much harder to work with than it really is. A lot of us are using a program called Neoscene which converts the 1080i/60 files using the cineform intermediate codec into proper 1080p 24p, it's fast and simple, and virtually lossless, plus it has a bunch of other benefits - the software is $100 but well worth it - it's a simple first step to the workflow and works very, very well.

Again, you have to be more careful how you plan shots when doing 1080, but so long as you do this, you should be okay, and I think with the right approach, you can accomplish most anything you want with the GH1 1080 mode, you'll just have to get creative.

It's not a perfect camera, but it's awfully good for $1500, the few hoops you must jump through are worth it for this kind of quality, in my opinion.

You are 100% correct. If you really know what you are doing 1080p in the GH1 is beautiful.
 
For some reason I see alot of people shoot in 720 60p and convert that to 24p? Am I correct on this? And if so, is that accomplished in Neoscene as well or can it be done in most NLE's?

Thanks

Typically, you can just drop the footage into a 24p timeline, and you should be good. Most decent-Good NLEs do this just fine.
 
I agree that for narrative work, 1080 24p can be considered but since the 720 60p mode hold up much, much better than 1080 24p when it comes to motion, I really do think that it should be used far more often especially for family videos, news gathering, sports and events although as far as live concerts is concerned, it all depends on what kind of look you want so either 1080 24p or 720 60p can be good. Some bands would like to have better motion quality. This is all concerning the GH1 since the 1080 24p mode isn't really that great unless your careful and for narrative work, your forced to be careful anyway.

no, you'd be seeing full motion at 23.976 frames per second (24p), essentially dumping the extra frames (aka, the "video" look)...smarter NLEs can discard such frames and give you a very nice look....this also depends on the shutter speed and the amount of "action" you are shooting, be it a paintball match, or a slow dolly shot. if you INTEND on doing slowmo with the GH1, your shutter should be set at 1/125 in 720 mode(or greater if you like the Saving Private Ryan look). for full motion 24p, your shutter should be set at 1/60 if you're shooting in 720 mode, and 1/50 in the 1080 mode (though a shutter of 1/48 is mathematically correct to a real film camera)...the GH1 has 1/50, which is very acceptable.

wait... if you drop the 720 60p into a 24p timeline it just removes the extra frames? how to you get slowmo if you want then? On a PC workflow...
