Something I don't quite understand. If you're shooting GOP1, why check the AQ setting at all? As I understand it, the AQ setting has to do with how the B frames (or B and P frames on longer than 3GOP) share data with the I frames in order to guess the motion between frames. As such, if you're shooting GOP1, since EVERY frame is an I frame, how does checking this value have any effect? Or am I missing and not understanding something?
HOLY MOTHER OF ALL THINGS CINEMATIC! (sorry, but me so excite. looks pretty raw, very crisp, no blocking or banding AFAIK.) Great job. I'll upload shortly.
Insane Extremity time: 220M GOP 1 AQ2 1080p24H. Try this out to just to see the detail! Don't shoot at Pappas Death Chart it will eventually die. Even Elecard Streameye can't cope with this. Will shoot at upto 125 shutter and probably beyond... The Elecard buffer analysis test looks great and its very very good quality if you like the effect of GOP 1 on the GH2. :-)
Why did I try it? Because we can thanks to Vitaliy.
Update: The picture and chart (Chris's Streamparser can parse these mts files - Elecard Streameye has trouble) are taken from a dark room with a single 800W Redhead light thrust my way whilst I'm spinning on a chair. Note: the mesh lines reflected on the white wall area is from the redhead cover). Panny 7-14 Wide angle lens 125 shutter.
@zcream Do you mean the flicker in the noise ? That will happen at high ISO settings with the in camera noise reduction turned on. I've noticed it myself and I put up an example of it here. Though the flicker is a lot more obvious in your footage. There are a couple of options, turn the noise reduction down a bit and turn the contrast up (increasing the contrast really helps the in camera noise reduction), or turn the noise reduction off completely and remove the noise entirely in post with Neat Video or similar.
The other option if you need to clean up existing flickering footage in post is to use a deflicker filter thats usually used to deal with unsynced flourescent lights, or inconsistent aged film (or if you've been shooting a time lapse shot). Just for info, I only denoised a tiny amount with Pixel Farms Clean software, deflickered with Nuke and did Grading and CC in Scratch with scaffolds.
@DancingCamera Thank you for the wonderful work! And I appreciate having nominated my setting. I verify thoroughly later.
BTW, although I stuck 66Mbps,3GOP compromise setting before, QV was set to 24 in order to use 24L mode. I also think that QV can be set to 22 supposing someone uses only 24H mode.
EDIT: Screen shot: 1st is 24H, 2nd is 24L, 3rd is 24H80%
EDIT: Sorry! 1st setting is wrong. 2nd one is correct!
I'll need to spend some time analyzing all you've offered here. One thing for sure the 14-140mm lens 132Mb/s example and graph really shows how well Driftwood's 132Mb utilizes data bandwidth.
I had time to do a bit more testing for steadicam motion yesterday. There's detailed settings information in the vimeo links below, as well as the ability to download the clips. I used settings that have received a lot of positive feedback, gleaned from my lurking around this fantastic website: Brandin GOP12 44M AQ4 Brandin GOP12 66M AQ4 Brandin GOP12 66M AQ2 Bkmcwd GOP6 66M Q20 Driftwood GOP3 132M AQ2
Thanks to all of the incredible testers and to Mr. Kiselev. I'll be donating again.
@driftwood I ran your 132M GOP3 and I think it looks great, even better than the 100M GOP3. This is a top-notch setting, and what I'll use for any non-spanning shots out of this camera for the time being. @bkmcwd Your 66M GOP6 Q20 settings work very well on steadicam, and similar to @cbrandin 's 66M GOP12 AQ2 (which, correct me if I'm wrong, your settings are based on?) - if it indeed can span then I will be using this as my baseline setting. @cbrandin 's setting 66M GOP12 AQ2 is terrific and produces comparable quality as @bkmwd with greater efficiency, but, to my knowledge doesn't span.
Here is a sample video with Driftwoods 150mbps hack. See the strobing! This is 24p in PAL-land, Australia at 1/50th shutter. Is there a way to minimize this ? I see this to a smaller degree on other shots as well - interestingly its a lot less using the EX-Tele feature. I know there are multiple threads on this - but Mr Eoshd had footage 24p at 1/50th on vimeo without this strobing. Just wondering what I am missing.
@5thwall At the moment I'm currently using the 66M GOP6 @bkmcwd just shared on here, mostly just testing it, it fits a very specific need for me really well. However I will probably continue to use the cbrandin 66M GOP12 AQ2 for most of my general needs, and I'll be using this new GOP6 for when I want that particular motion look (and probably mostly for outdoor shoots, or for very well lit shots in general). So, to answer your question simply I'd say the cbrandin 66M GOP12 AQ2. Its rock solid, and incredible looking footage that stands up really strongly in post.
I don't ever take shots longer than 5-6 minutes, so spanning isn't a concern for me. If I did ever need to take really long shots (unlikely) then I'd drop down to the cbrandin 44M GOP12 AQ4 and use it's 24L 32M setting which has always spanned when I've tested it. But who can say what the next ptool version will bring, maybe we'll be able to get a GOP6 or a GOP3 at the lower bitrates that can keep the image quality right up there with the cbrandin GOP12 settings accross all light/scene conditions. If that happens I may change my decisions again. I don't personally like the way GOP3 looks. I do like GOP6, for specific subjects its beautiful to my eyes (specifically when shooting physical artistic performances, dancers etc.) For everything else I'm more than happy with the GOP12. YMMV
@Stray Sorry! Since the problem of a card error and cadence had occurred in QV20 in 24H80%, I changed into QV22. It seems that its 24H and L, 80% are all stable in this setting although I frame size becomes somewhat small. There is a problem of span, of course... Please try.
