Jitter/choppy playback - solution? GH4 same issue?

cogumelo — Fri, 11 Apr 2014 07:42:08 +0000

I'm still having trouble to playback MOV 1080 60p footage from my GH3 on my macs (a macbook retina displays and a MacPro 8core 24GB Ram). Those files playback normally on the camera, but it's quite choppy or jittery on my computer, specially on pan movements. Does it has a solution? conversion or transcoding? Is it a mac problem? a codec problem? or GH3 problem? I also got jitter recoding on all setting of 1080 60p, using my other camera, NEX 5N, that also records 1080 60p AVCHD I got no problems at all, the files playbacks just right, but I also think the NEX footage is 59,94i converted on camera to 60p or 59,94p... I don't now... I think if maybe the gh3 were capable to records 60i in MOV mode it wouldn't happen.... I think the problem is due the progressive fields, or YUV to RGB conversion problem....I don't know... because when I transcode the files using 5dtoRGB software, it gets better, less jitter, but they still there! If we're having trouble to playback 1080p 60p, can you imagine what gonna happen with the 4k files? I've pre-order a GH4, but I'm thinking twice if it's worth to... I don't want more headache with playback issues... I'm thinking to move to Sony A7s.... That's SAD!!! Anyone knows the real reason why we can't playback those files??? what should I say to my clients that got choppy footage? my camera is rubbish! or your computer is rubbish!??? WTF? That's just sad!

GH2@ Stuttering when panning or with any kind of movement

I have a GH2 and am still getting stuttering footage when I do any kind of pan or shot that's not static. I have tried using different shutter speeds, but that doesn't seem to help. I usually shoot on 24p and with a shutter of 50, but as I said I increased to a faster shutter to see if that made a difference which it did not. Your thoughts?

BTW, I am using class 10 SD cards so it can't be the card speed that's holding things up.

Jittery footage from GH2 when tracking/panning .. why's that ??

Hi, I just shot a short promo for an events company and the pans and track seem to have a jitter to them ... look here http://vimeo.com/user1415033/review/83892278/e7e9cd0822 It was shot in cinema mode at 24P (which I believe is actually 23.976) at (probably) 50th sec

I've also just seen this on YouTube which seems to suggest that this footage ALWAYS has a jitter to it ..is that right??

Any advice would be much appreciated....

Thanks

Alan
