AVCHD high bitrate tests- MUD FREE footage

[tommygdawg]

I've been testing with the D setting and what's weird is in 720p I can get around 35mb/s with my shutter speed at about 1/200 if I shot the same scene ( trees and bush ) with a 1/50 i would only get about 10mb/s and the there isn't enough detail.

It's because a lower shutter speed gives more motion blur and thus less detail in movements and thus a lower bit rate (I think ).

Has anyone tried a green screen shoot with these new hacks? Regular GH1 codec did not work for my purposes (much too blocky). If there's there's noticeable improvement in regards to keying this new footage, then I'm pumped (already pumped that there's no more mud).

Count on it. That's the first test we're doing at Rainfall.

If you check the reel ( www.rainfallfilms.com/showreel ) about the third or forth shot in is with a 5D, the guy with the cowboy hat walking through the canyon.

5D wasn't all that great, but it worked for now. I think the GH1 will melt it in comparison once converted to a 4:4:4:4 or uncompressed space.

Love the Cat digging thru the flower pots on the 720 samurai shot....
Quick question to Tester or Jobless.

Are these all the tweaks with these setting? or are these being left out (default)?:

MJPEG Size 1280M = Ticked
MJPEG Enco 1280M = Ticked
MJPEG E1 Quality = 400
MJPEG E1 Table = 103
MJPEG E2 Quality = 350
MJPEG E2 Table = 116
MJPEG E3 Quality = 250
MJPEG E3 Table = 120
MJPEG E4 Quality = 200
MJPEG E4 Table = 125

Doesn't matter... These are for MJPEG only. You can chack them or not, they don't influence AVCHD
The cat is callled Nutella... You got really good eyes..

Unquestionably there will be (or at least SHOULD be) a substantial improvement in keying quality. The codec is far more robust and accurate now, and if you use the 24pN patch you get the "good stuff" - 24p progressive chroma, instead of the interlaced chroma that the 24p-within-60i version gives.

big improvements for the GH1 world! Just sold my GH1 for a 7D or I'd be all over this.

 

[jobless]

I just tested out D setting with native 24fps. Oh man.. IT IS BEAUTIFUL..

Yes, samuri pan in SH mode will cause the camera to stop recording, but when will I ever need to samuri pan? NEVER. It handles just fine when panning faster than normal.

Yes, It's true. But occasionally you'll have some scenarios that D settings in 720 mode want hold.
For example:

From 30 sec to 1 min

Barry my question to you , once yo compared a cheap lens to an expensive lens,and you said that regarding shooting video it make not much difference ..now with all these extra robust codec,does this change things regarding lenses or do you still think we are still far from seeing the difference from a good lens to cheap lens ..thanks!

 

[jobless]

I tried this setting and I'm getting weird splotchy artifacts at 720p as if the bitrate is too low. I just did a test shot of my room right after installing the patched firmware, so my iso was set to 1600. 1080p mode doesn't seem to have these artifacts. Maybe I set one of the parameters wrong?

Here's what I'm talking about: http://dl.dropbox.com/u/1017296/splotch.MTS

Nice finding!
I checked and I have problems on 720 with 1600 and 800 iso with this settings...

Good question. Barry might be able to test this as well.

 

[nobbystylus]

anybody got any reliable settings for AVCHD? I'm not getting reliable results from Jobless's settings, getting glitches and stuttering with those..

i'm also not noticing any improvement in lowlight in terms of mud and codec nastyness in dark areas.

I used joblesses settings with a Sandisk 200x class 10 16gb card.

 

[Psynema]

Do you guys notice an improvement WITHOUT pixel peeping footage you would have used anyway? (usually during quick pans, you cut that stuff out of a final edit anyway).

But does anyone who installed the hack find their footage more 5D ish ? LOL.

 

[PappasArts]

I think just aesthetically, it offers something different. It almost looks like HPX3000 footage or Adapter footage versus Straight DSLR video footage if that makes sense.

Totally understand. It's the codec. AVCHD codec looks more Video, edgy to me. MJPEG's tonality is smother and feels dense. Like high bit rate codecs are.

Here is a shot done today with a macro on the GH1 in 1080P mode

Can everyone stop posting for about a week - I've got to get some work done!

I'ts extremely frustrating - I've got 2 GH!'s & so much editing to do I haven't got time to have a play! - it's just EDIT, check the forum - RENDER, check the forum - BURN, check the forum
:badputer:


I think we need to design a TShirt that prople can buy (profits to the fund)

TESTER13 rocks!

Mjpeg looks nice...
But you need to shoot some wide shots with lot of details!!!
It's just upscaled 720.

It's not upscaled in camera I believe. I have never had any of the best of 720P look anywhere near that. If that is up-scaling, then Panasonic needs to sell that chip to Hollywood.

More shooting of-course needs to be done.

Yes, as we've seen from Pappas' earlier testing, his upscaled 720 looked much softer. This 1080, if it's upscaling--I'd have to agree--I'll have some of that.

It reminds me of HPX3000 footage, and the AVCHD reminds me of EX-1 footage.

Pappas used a great term, I remember using it when I first got to touch an HPX3000: Dense. Thick. Heavy. Full.

Good thing it won't hurt to have both if we can get 24P out of it.

 

[jcintron]

Good for 1080 Only

Good for 1080 Only

These are good for 1080 only... is there a good compromise for 720 and 1080? (Other than factory default?)

Video bitrate adjustment simplifed TEST:

Without buffer option checked
Video bitrate adjustment simplifed 38000000
Overall bitrate adjustment 40000000
Limiting bitrate adjustment 42000000

1080 --- 36 653 036 kbps ( no problems)

720 --- 33 927 580 kbps (no problems)

Indeed "Dense Thick. Heavy. Full." That is how it feels. When massaging it in post. It just feels right!


Great analogy EX1 vs HPX3000. Both are good, both produce nice images. Just the HPX3000 is just different... In a good way.

Man, I would attach one of those to my bank account, credit line, chick magnetism, carrer; why hell I would attach that chip to everything. :-D

Hahah! I know what I'm about to attach to it. >:] Master Primes.

Pappas, you got PM. Need to know what SDHC card you have, getting my GH-1 tonight.
