I just tried the Sanity V3.1 hack on the GH2 using one of my old PNY class 10 card and I notice that the writing also stopped after a little bit of shooting. I then put in the Sandisk class 10 card that I just received in the mail today and was able to shoot much longer and it did not stop writing. I only experimented for a few minutes and granted the Sandisk card is fresh out of the package.
It was the 720p SH mode that I tried and as far as video quality is concerned, I'm impressed.
This version of SANITY fixes a missing zero in FH mode and makes it useable. I set FH bitrate to 32M based on gameb's report of successful spanning at that bitrate.
just shot some outdoors with sanity and noticed some oddities on my panna class 6 and transcend class 10. 20mm AF f16 1/125th ISO 200
shooting SH at 44Mb - works shooting FH at 33Mb - works but bitrate is around the 3-4Mbit (just checked and the ini file is missing an extra 0) shooting FSH at 44Mb - write error shooting 24H at 66Mb - works
whats good is with indoor shots with shutter 1/25th 1/30th Bitrate doesn't drop like it used to with the GH1 in 720
Thanks Ralph. working on my panasonic class 6 at night. will test tomorrow outdoors. How does one incorporate the 40fps prolonged burst rate mode into this patch? that would be the icing on the cake for me.
I would also like a hybrid patch that @PixCanFly suggested. This would give us the ability to capture high quality 720p 60 and 1080 24 in one convenient setup :)
@filty It's possible - I'm suspicious of Transcend cards in general. I had a 16GB Transcend that went bad. The replacement they sent me benchmarked 5MB/sec slower than the original. Who knows what goes on under the hood with these cards. Oh, and then yesterday, the cover just fell apart for no apparent reason.
@Ralph_B Definitely not stable on Transcend 32GB class 10 card. 720/60 crashed whenever stressed with a lot of motion or detail. Usually between 5 and 10 seconds. Also, the images seemed unusually noisy. But that could have been the ISO bug. Was really hoping this was the one as I need to shoot a fair amount of slo-mo. Didn't have any other cards with me, so can't verify if a Sandisk would've held up better. Had to fall back on the old reliable HPX170 for the rest of the shoot. Maybe it was a limitation of card?
@driftwood No, I haven't posted any tests. What I've come to learn is that motion cannot be fairly judged by a still frame. You have to see it in motion (duh...).
@gl Don't know how it compares to Chris' 66M. I've only compared it to Quantum 5 and HDMI output, and it's very close to both of those. Basically, I'm thrilled with it - even the 44M, which I find myself using more and more.
@gameb When you say 24L spans, are you using 44M or 32M?
That looks good @Ralph_B. Just streameyed it (720p60) and its very pleasing. Well done mate. :-) Need to do some motion tests now. Have you posted any?
@Rtwalker about 90 minutes in 720P mode and also in 24P Cinema Mode, because I changed the settings. Both are 44Mbps and 32Mbps. Right now I am checking if it spans and it looks like it does span.
Here's the latest version of SANITY. The only difference between this and v2 is the change of "Auto Quantizer for 1080 mode" to AQ4 from AQ3.
This should work fine with any Class 10 card.
Just to repeat, the 720P modes in Sanity are the best I've seen. If you want to shoot 50P/60P you should check this out. Sanity's 1080 60i is also the best I've seen.
Looking for a 720p patch for the GH2 that will give great quality, but longer recording times. I love the Driftwood patches for narrative, but I have an 8 hour run and gun shoot coming up, so I am looking for reliability and long record times. Currently using mpgxsvcd 32mb 60p settings....but for some reason my estimated record time on a 32gb card is only 1 hour 32 mins? Any thoughts on this? Thanks for everyone's great work too.
Do you think a Transcend Class 10 card would be sufficient to try this patch out? I'm not well versed on the different card abilities, so any thoughts would be greatly appreciated.
