Official Low GOP topic, series 3

toxotis70

Is there any bigger SD card (64 - 128 GB) that is combatible with GH@ and those settings ?

toxotis70

@Driftwood ... is it possible to make a patch with lower bitrate for 24p but keep GOP1 (all others the same) ?
I don't have a big card, and would like to save some space.

@Jspatz
Thanks mate! :-)

@HillTop1
Welcome! ;-)
"What's the bitrate at 24H and 720p60 then?"
I think that it will be about 60-70M usually as a matter of fact although 24H is set as 176M.
In 720p, I have adopted the arrangement of Chris as it is, and since I am not using 720p at all, I do not know.

I have a big question about these patches.
Remember, few month ago, some of us have encountered an issue with their 66mbps hack : Camera crashed when the .mts hit 4GB. At this time, we thought that the card speed limits was the problem.
I have tested 2 rates at 166mbps and 50mbps, with the AQuarius 2 patch. (Other Values remain the same). Camera Crash after 4GB, both in 50mbps and 166mbps (even if the bitrate was under 50mbps in the second case). I use a SanDisk Extreme Pro 45MBps, so, write speed should not be a problem.
So, do you think this problem is due to the video buffer or something else ?

@HillTop1 Still editing the project. Looking good :-) SeAQuake is kinda cool :-)

HillTop1

@bkmcwd great thanks, will check it as soon as I get home. What's the bitrate at 24H and 720p60 then?

@driftwood looking forward to test out SeAQuake as soon as I get home. I think I will start bringing my GH2 to work lol. I love your nomenclature of your patches lol. What's the bitrate at 720p60? On a separate note, how's your collaboration project coming? Dying to see the finished product.

@bkmcwd
This is my favorite patch so far. Best IQ. Spans in most cases and seems to play on everything.

driftwood

@FGCU 166M for H. Its primed to the buffer fullness, dont need 176M, you can raise the bitrate higher if you like to no advantage - the i frames won't get any bigger.

@FGCU INTRA GOP1 - only 720p60 is GOP3

@All @toxotis70 Panasonic has a funny way of dealing with PsF. Read this;-

and more info here;- http://provideocoalition.com/index.php/atepper or http://www.allantepper.com/englishblog/

This is a good program to identify benign or malignant PsF and other mts modes.

The economy patch of Q18 was renewed.
Although the bit rate exceeds 100M under high stress, I think that this becomes the about an average of 60M bit rate usually.
With this patch, since frame size is not compressed even if moving a camera up and down in woods, I think that I will give the name in connection with woods or forest.
It is the same as usual the arrangement of Chris except 24p.

@HillTop1
I am sorry that I did not reply to you sooner.
Since 88M patch is not so good, try this instead!
I stick my done patches on "GH2 Patch Vault, most popular patches in one place" thread. :-)

@driftwood you really made changes to the your new SeAQuake! Can't wait!

How we make 50i PSF material to show in NLE (i use FCPX) like 25p ?
I want to make a video with footage from my nex 5n (25p) and GH2 (50i psf).
when i put my gh2 footage in the same timeline with original 25p , it show me that it needs render....

@driftwood
It looks great!
I can study many things again. :-)

@Driftwood
Looking closer at your chart, I see it quickly drop from the h rate to the l rate, which is where I want it to be. Why should I care about those early frames when they do not appear to cause any practical interference? What should I be worried about? Thanks

alcomposer

@driftwood, @Jspatz darn! I left my GH2 home and am out now! Got to get it to try this out! :(

Jspatz

@driftwood
Every test has been rock solid. How should I expect the buffer under run to manifest. VK mentioned that 3.63 allows very low 24l bitrates. Could that be why this is working for me?

alcomposer

@TrackZillas I recorded in 720p 50 (as 60 is not intra). Not that happy with 1080i -> slowmo- (kind of dislike all the work to get 540lines!)

@Driftwood
Thank you very much for your new patch release. For me, the great news is the ability to get 25 P via PsF. My doubt is about the workflow to get this. Any idea?

TrackZillas

@alcomposer Great looking snapshot here how is the new 720p 60 working? is it glitchy at time?

TrackZillas

@driftwood Your the man Driftwood you never stop with the improvements. So that means the new patch is upgraded for the new Ptools than..

alcomposer

@driftwood filmed a video installation with the last intra, super image! Even at 720. Would have loved to send it into the collaborative project.... Will post a few scenes...

PS: Lens 35mm Samyang 1.4
PSS: Image not original 720p - sorry- will repost when I have file at hand :-(

disneytoy

Thanks Drift!

driftwood

@alcomposer fuckin' right man!
@Oedipax Never lend a camera, youre asking for trouble!

Oedipax

@driftwood, thanks again for all your hard work! Now if I only had my GH2 back (a friend is borrowing it)!

Howdy, Stranger!
