FCP's kind of a lost cause unless you have all the directories that go around the .MTS clips. Then you still end up transcoding to ProRes or AIC or whatever. Cineform Neo Scene is a pretty nice workaround for now, if I end up getting a GH1 I'll probably buy it. Either that or see what Apple does in the next FCP release
I have a theory. I think that the camera is dropping frames and messing up the 3:2 cadence. The interlacing is all over the place and definitely part of the reason for some of the macroblocking. Hmm, I hope this gets fixed, but I bet it wont. Also, this may be caused by using SDHC media that isn't fast enough to write the data. Keep in mind, even though SDHC class 6 is fast, when it is completely full, it has to rewrite blocks and this will be slower than when the card is completely empty. At least this is something to try before dismissing this as a cmaera fault.

It is not a surprise at all. Interlaced encoding shouldn't be used for a progressive output -- that's for sure!I've noticed a lot of interlace artifacts even after pulldown in "countryside...1080". Does it mean that coder is unaware of interlaced structure and simply compress video on frame-by-frame, not field-by-field basis?

A couple questions maybe SonicStates can answer which could help a little to understand what's happening. On the 1080 Countryside- Shutter speed looks to be around 250? Was this camera in Auto, AP or SP? OIS turned on or off? Any idea about the the detail/sharpness/ISO settings?

Sonicstates thanks for the all the effort in the uploads.. Please make sure Illya knows when you've uploaded the new files.
Your optimism is encouraging. I've seen some really interesting stuff coming from Philip Bloom, for example.So I watched the 1080/720 Countryside and Train Jello Tests on my 102" screen.
First of all I want to make a quick comment- it's asinine to jump to any conclusions or make any definitive assessment of camera performance based on the 'countryside' clips! No overall assessment can be made on the GH1 from these clips (Sadly, it seems that someone did just that on a different forum I read today).
Ok, back to my opinion- which as it turns out is essentially the same as Ian-T said earlier; playing at normal speed this artifact is NO worse than another long GOP codec, found in some cameras commonly available around $5K USD. Which certainly looks better than the MPEG4 codec faults in my HD DirecTV DVR!
Watching all this stuff at 60i/60p for the first time, the artifacts didn't make me fall out of my chair and clamor that either the 1080 or 720 was unusable. The GH1 has so many pluses in the image quality, ergenomic and (especially) price categories, over other frequently mentioned cameras, I think this will be a non-issue for the vast majority of GH1 owners, especially those that know how to shoot.
Yes, the same artifacts are present in the Countryside 720 just as in the 1080 version. In case anyone has any doubt, pause when bright/contrasty foliage passes close to the cabin window, and step through frame by frame- same codec faults.
Watching a portion of each "Countryside" clip (720/1080) frame by frame during a few seconds with a lot of motion- that is- handheld, seeking focus, exposure compensating, extremely fast moving (close to camera) foliage, was the most egregious. When all that high-frequency detail zooms past the camera, there's really not much that can be done. However, the good news is that is that it's EXTREMELY unlikely someone would choose to shoot/playback this way for creative purposes- that is stepping through material shot like this- frame by frame.
I'm slightly more concerned about the codec faults on the wider shots with less up-close foliage. However, based on what I'm seeing during these moments, I think that all the rapid scenic change combined with continuous "auto" mode adjustments during the shot significantly contribute to the overtaxing of the codec. It'll be interesting to do a small test to compare codec tollerence in manual vs. auto. I've also noticed "auto" mode contributing to codec problems in HDV.
I watched the "Lemon Soju" clip 0006 on the big screen, while not particularly detailed- you get some idea of what's happening with the running commentary track. As further eveidence of my theory, each time the camera operator suddenly changes shutter speed/exposure during the 'out the window' shot, there are momentary codec faults in some areas of the image- subtler than the train obviously; but still present. These same codec faults are not immediately apparent when the camera is just experiencing handheld motion and concurrent motion from the subjectmoving across the frame. Testing could reveal if "auto" mode is a contributing factor of codec fault, as I said- I suspect it is.

Anyone have any other examples like this? I'm interested to see them.
I meeting up with someone who has a GH1 and plan on doing a few quick shots this weekend. Probably no codec "testing" going on, just beauty shots and that's fine by me.
I've seen some original .mts files that haven't (actually can't) been posted on-line and I'm feeling confident that when the GH1 is shot poorly, it looks like other cameras/formats shot poorly- crap. However, when it's shot well, the camera yields result similar to MUCH, MUCH more expensive HD cameras, so the GH1 is probably the greatest bang for buck camera on the planet right now, and takes fantastic stills to boot. When GH1 material is transferred to 35mm, I think the feel will be quite similar to a S16 blow-up, although this remains to be seen. I'm working with two professional facilities in Hollywood right now to facilitate a quick D.I./35mm film-out test. I'll keep this forum posted as results roll in.

But going with any film-out test, do NOT forget to test the codec in every AVERAGE situation the codec faces out there. Not only those kind where it is possible to state this camera is able for the job.

If you won't be minimally scientific with your experiments, what for they serve after all?
I'm referring independent tests for sure, not good marketing on brand advertisement for camera sales.
