I am in PAL land here things are easy to choose 25P HBR on GH2 and the 25P PsF wrapped as 50i from the GF2. I would agree with you 29.97 and if you need to go to 24, deal with it

Stonebat is correct. 720/60p on the GF2 is really just 720/30p with each frame repeated twice. Before I hacked my cameras, and before the GH2 got a real 30p mode (and before I figured out the 80% speed trick), my solution was to shoot the GF2 at 1080/30p and the GH2 at 720/60p, and editing them on a 720/30p timeline. That gave me the option of just downresing the GF2 to 720p or zooming and panning around as the scene required, and I could get slow motion from the GH2 footage when desired. Now, I'd probably just shoot 1080/30p on the GF2 and use the 80% variable speed mode on GH2 to get 1080/30p on that too, except if I really needed an audio track to aid with syncing, in which case I'd use HBR 30p mode. But the quality on 24p modes (sped up 80% to 30p) seems to be much better than the HBR 30p modes.

It looks like 720p60 because of AVCHD standard framerates, I think :-)

yes, totally agree, however, story will look like crap if you mix different frame rates. i spent the last 2 1/2 years of my life focusing on content/story making my first film on gh1 http://www.menoflamancha.org/ (mixing with hv30 as well), but needed the help of others to straighten out the mess of various framerates i had (which this forum's LPowell helped tremendously with), which included hours and hours of transcoding on 8 core computers.

i shot mostly with 60p because gh1 had crippled 1080 codec but thankfully it worked out, after shooting some 80 hours of footage i could use slo mo when needed and have a nice smooth motion when recording fast moving shots from car, etc, which 24p IMO is not always great. slo mo is priceless to have ability to use. that is why i think 48p is ideal to shoot in all the time, because you can drop on 24p timeline and it throws away useless frames unless you need them! but so i dream!

and my second film i imagine will not have that option since i shot with 24p

(though i had the handy gopro shooting at 50p off the airplane). this is the kickstarter appeal video btw.

i noticed that res Lee, totally makes sense. thank you, I'll check out that patch and modify

thanks keithL. i can actually sync without a dual track but it is difficult and i would say too time consuming. i will either shoot both in 1080 29.97 or the question i wish someone would weigh in on is:

can i intercut 25p footage from gf2 with 24p footage on gh2. will there be stutters and light flickers? or just light flickers in certain indoor lighting? any opinions out there from people that have done this on other than small tests?

there is some interesting stuff on conversion here http://www.reduser.net/forum/archive/index.php/t-5704.html and http://www.gearslutz.com/board/post-production-forum/464825-25p-24p-blu-ray-audio-issues.html

apparently there are two ways, interpret footage which will drop one frame and look jerky or decrease speed by 4% which is better but sound is off. most people will use gf2 as a b cam so sound probably is irrelevant. but i definitely see the light strobing when i film my computer monitor in 25p and none in 24p. this is because of the Mhz differences.

hopefully this will help others that want to use both cams and shoot at 24p.

i think i will settle on 29.97

I got some great advices here: http://personal-view.com/talks/discussion/2956/how-do-you-combine-gh2-23.976-fps-footage-with-gf2s

@KeithLommel

"720/60p on the GH2 and cutting it with 1080/30p on the GF2. This matches resolution between the two cameras better, and gives you the added option of slow-mo on the GH2 footage."

@balazer

"I suggest making your target format 60 fps, which will support 24 fps and 30 fps cleanly"

(Drop 24 and 30 fps clips in a 60 fps sequence)

why doesn't anyone approve of shooting in 25p and using the interpret footage as 23.976 in Premeire. Yes this slows footage down 4% but GF2 is meant to be a stunt and B shot cam to the GH2 (in my opinion) so in my case it will not be used for dialogue or sound capture. It seems like the best over workflow, rather than conversion which loses resolution and is a general pain. I am intercuting some gopro footage shot in 25 and 50p and you could see the frame skip when intercuting with GH2 when not first interpreting footage as 23.976 and 48, but if you take that step first seems very smooth to me. I don't like idea of shooting 720 60p because the trend now is 1920x1080 and in the next two years we will see lots of cameras pushing the 2500 and up.

25 fps solution is great. GF2 will look like crap @ 1080 unless you use it with longer (in my experience 35mm+) lenses for close-ups. Non-native glass helps, particularly older lenses that have lower contrast. You don't have much control over GF's output, you can however match it with GH's settings.
