But they can fix shutter speed at 1/60, and the video resolution beats my Canon HF10. They are underrated cameras, IMHO.

Not to hijack thread, but thank you for the post on the Samsung. I've obtained a 1080i50 sample and it has a clear problem"

SAMSUNG AVC encoder, 1920 x 1080 (3413 x 1080), Millions
AAC, Stereo (L R), 48.000 kHz

It does have a frame size of 3413 by 1080 in the QT player and iMovie 09.

1) Could you post data from 720p60.

2) What NLEs have you tried?

Thank you.

Steve, sorry I missed seeing your last post until now.

I agree the Samsung has some codec whackyness going on. When you first connect the camera by USB to the computer it auto-installs proprietary Samsung codec, after which Windows Mediaplayer will play the clips fine.

TMPGenc Xpress4 opens the clips, and reports 1280x720 59.92fps, with 48000kHz mp4a audio.

I've been transcoding the clips to CFHD avis using HDLink. HDLink seems to be confused by the reported framerate and outputs 25fps clips with the audio way out of sync. If I run AVIFrate on the clips and reset them to 59.94, the audio re-syncs. I put a trouble ticket in to Cineform about that ... they said they are 'waiting on new AVCHD components' that may fix the problem.

I have a few seconds of CFHD 720p60 I can send - it's 80MB so what the easiest way to get that to you?

Their MSRP would take a hit if they did.

The GH2 ?

Do you use VoltaicHD to convert your AVCHD to something else for editing?
May I ask what you convert to?

I don't use it as I shoot with h.264/AVC because I don't have to convert it. It seems odd that I can edit AVC natively, but AVCHD which is essentially the same thing so often has to be converted.

Unless I can a dramatic increased quality of AVCHD, I will use Motion-JPEG.

PS: Pana's Motion-JPEG is identified by OS X software as Photo-JPEG. Very odd.

could someone clarify a point about the GF1...

on dpreview.com there is a picture of the GF1 with the GH1's 14-140 lens on it and it says...

"Using the adaptor, the G1 can mount the full range of legacy Four Thirds lenses. However, its smaller size can result in combinations that are less well balanced than would be the case with Four Thirds DSLRs."

Now I have a GH1 and was considering buying a 20mm 1.7 panny prime. I then saw its only slightly more with the GF1 body. However now after reading that a converter might be needed to use the 14-140, could someone confirm that the 20mm 1.7 that comes with the GF1 is the same as the 20mm 1.7 that people generally buy for use with the GH1?

Many thanks in advance

yep - same micro 4/3rds mount - I swap all my GH1 lenses on to the GF1
