got a music video shoot tomorrow. I can see Cluster v4 has problems. Can anyone recommend a safe 720 50p setting?
Thanks
@Benibube If you could let me have a mts file from any of those failures i'd liike that. Ive seen this before - buffer problems. I think I can fix this problem. Could you dropbox me asap. I also need to double check that your mts file repeats your problem thru my workflow. Thanks.
"Thats a very nice start for a new GH2 adopter. Just remember to watch your ISO bugs as things can get a bit noisy on 320 / 640 ISO unless you switch down from a higher setting. And Welcome Aboard GH2 land! :-)"
Is the noise does not disappear if the switch from 640 to 320!? I have just such a situation. Where can I read about it?
@driftwood - amen. What you've created here is a game changer. And its not for boob tube or for U tube. Watch the stuff on a big screen! The tangles might persist between users and yourself, but the end result is this - THE FECKIN CAMERA IS MUCH BETTER thanks to Vitaly , You - Driftwood and all the other brilliant techno-rotters involved. So thanks! With a capital THANKS.
@Driftwood I'll take not bad but better than stock in 720 and brilliant in 24P!
Zzzzz Guys, youre never gonna get a brilliant HBR or 720 setting on the GH2 - period. Its simply not powerful enough... Dontcha thiink we'd have found it by now? Its not bad but it will NEVER be brilliant. Take for example 720p60 - it goes shitty as soon as you go over a Max GOP Size of 1,000,000 Bytes.
If you don't believe go and create some settings.
I don't know Bonzai....I had a good night with Cluster 4. No lockups and very fine grained noise up to ISO4000.
Today it did well until I left the polarizer on after I went in deep woods. IQ suffered badly but that's not the patch's fault.
I was testing flow Motion 2.2 at the same time and surprisingly, it locked up once and required me to remove the battery. That was on a light colored tombstone and Cluster 4 handled it without problems.
Spanning is low on my priority list (30 second clips are 30 second clips) so I didn't try that and I didn't have time to test it on running water which locks up everything (almost).
So far it's been stable with good IQ. I do wonder if it's any improvement over Sedna though.
I prematurely declared Cluster v4 stable. I did have 1 lock-up at about 3 seconds last night but subsequent 1 minute tests at 30 fps/HBR ISO 3200 went smoothly so I wrote it off as a fluke. I also tested 30 fps/HBR in full daylight ISO 160 with adjustable ND Filter on blowing leaves, pans and zooms and had no problem.
Therefore I loaded it for a trip today at Foxwoods Casino (I kept V3f on the card just in case. To my amazement while shooting what looked like a non-stressful sequence (20 second pan across the floor and up a wall ending on a skylight dome) I experienced 3 failures (2 write errors and 1 lockup) out of 6 attempts (And I was quite careful with pan speed on the 3 that succeeded). Average total bit rate on the successful shots and the write error shots hovered around 62 mbps. Average I frame rate (once it got up to speed hovered around 450,000 bytes.
To add to the mystery after I got home I tried 30 fps/HBR on low light and the out doors shots again an no errors with not much change in bit rate and I frame size....
Wheather was sunny and more than a fresh breeze today (~6 bf), so I spent (probably too many) hours testing some patch settings.
I first shot some reference material with GOP3ZILLA (which I have used a lot already), next I installed Span My Bitch Up v2b, and indeed this was the first GOP1 setting that was (unlike the other GOP1 settings I had tried before) stable enough for me to do some actual quality tests.
All tests were done on a freshly formatted SanDisk 64GB 95M/s.
Recording the "moving tree leaves in the sun" scenario yielded a bit rate of ~100 MBit/s in 24H mode with Span My Bitch Up, the result looked very similar to the ~95MBit/s 24H recording I shot with GOP3ZILLA before, with a very slight favor that I would assign to GOP3ZILLA because of some minor "staircase" artifacts I saw in the "Span My Bitch Up" recording near thin vertical branch lines. I also tried 24H mode with ETC, and there were some very visible "horizontal bands of slightly different color" in the less bright areas of the image - I had not seen such while shooting 24H ETC with GOP3ZILLA. Since this effect is better visible "in motion", find attached an animated GIF for illustration - look at the tree trunk in the lower middle.
The "24H" recording stopped involuntarily after 3:23s with the usual "card speed" message.
Recording the "moving tree leaves in the sun" scenario yielded a bit rate of ~87 MBit/s in 720p60 "SH" mode. The IQ looked very good, but not visibly different from the ~50MBit/s 720p60 recording I had done with GOP3ZILLA before. The first 720p60 recording went fine, a second and third take stopped involuntarily each after ~3 seconds with the usual "card speed" message.
I tried 720p60 "H" mode to see whether that was more stable in the test scenario. It is, but this mode yielded a bitrate of only ~22MBit/s, and the image quality was consequentially very poor. (I guess the patch setting wasn't really designed for that mode?)
My attempt to record a 30 fps HBR video resulted in an almost immediate camera crash, had to take out the battery for revival.
(I also did some low-light test shots with Span My Bitch Up v2b, they will be discussed in comparison to Flow Motion 2.02 in the FM2 thread.)
@driftwood thanks for explaining the diff. Q20 vs AQ1..
@nchamberlain13 Thats a very nice start for a new GH2 adopter. Just remember to watch your ISO bugs as things can get a bit noisy on 320 / 640 ISO unless you switch down from a higher setting. And Welcome Aboard GH2 land! :-)
@oscillian At the moment its very close between SMBU v2b and β Pictoris. Remember there are four flavours of β Pictoris to choose from. Experiment.
I just got my GH2 the other day and hacked it with Orion v4b. Thank you so much Driftwood for the amazing work you do!
