AVCHD high bitrate tests- MUD FREE footage

As for test results using low level analysys:

Only D setting is ok at low level.
All others contains large waste of space as your bitrate is consumed in garbage large size spike frame.

Plus low level show it as native 23,97, but MediaInfo show as 47,952, and player also tries to play such.

Does that mean that optimal values are around D settings?
After effects shows 23,976 fps...
 
size of prores file generally depends only from type of prores codec - i.e. HQ or LT or other, fps and resolution

That's what I was assuming - that file sizes would stay about the same from the ProRes transcode.

It's the conversion to PRORES that typically eats up all my storage (for documentary work I have hundreds of hours). I normally put the original MTS files offline on cheaper storage, so size of the original footage isn't as much as a concern for me.

This is actually more exciting for me at the moment, since there seems to be less length limitations than the MJPEG mode!

The GH1 game is about to change. :nads:
 
Amazing work guys!

Has anyone confirmed:

1) Length limit with these new settings?

2) With a higher mts bitrate is transcoding to ProRes going to yield larger file sizes than before, or the same sizes? Just wondering for workflow and storage issues.

This is some exciting news nonetheless!!

I recorded 2 minutes for C and D settings and then I stopped the camera...

A 10 or 15 minute test would be great if someone has the time. If not, I will try to do some tests with it this weekend!

Thanks for the great testing!
 
I would like to know the settings to get playpack to work

I would like to know the settings to get playpack to work

I haven't been able to follow close enough to learn how to get the 'playback' functionality to work.

Right now, my experience is that using the Real 24p setting, and the High bitrate AVHCD settings does not allow playback for me. Others can set me straight though, because I would really love playback!
 
Just tick version change(remember to increment every time), time limit(for pal people) and the settings as tester13 has indicated on pg1, that's it, use the settings above that jobless initially gave(the ones that are gooood) and everything is good to go, do not tick anything else, not native 24p if you want to playback in-camera. The quality is looking truly awesome imo, but I am a complete amateur. After that you can go with jobless d, or go straight to jobless d if you want. Tester13 has turned a huge corner, Panasonic should buy the code from him or pay him handsomely to implement, this is huge r&d cost to Pana, they could pay him as freelance imo and release as official f/w

GH1 Footage from Jobless "C" settings and Field of Flowers

GH1 Footage from Jobless "C" settings and Field of Flowers

I have made an update and am using the 'real' 24p setup. I have changed the bitrate to match Jobless "C" settings and here are the results.

Steadicam Merlin, GH1, Schneider Xenon 28mm F2 (@F11/F8) and one Really nice field of flowers, this is straight out of the camera, no curves (slightly over-exposed) no contrast, nothing....

SUPER stats tells me this file is Overall Bitrate 36.7 Mbps, Maximum Overall Bitrate 46 Mbps, 23.971 FPS, 1920x1080, 4:2:0 color, Bits (Pixel*Frame) .705, Duration is 26s 958ms.

Video bitrate adjustment - a) 22.000.000 b) 32.000.000
Overall bitrate adjustment - a) 24.000.000 b) 35.000.000
Limiting bitrate adjustment - a) 26.000.000 b) 40.000.000

I started panning after 5 second of the footage...

Hi jobless, I had a look at your footage, quite good! What I noticed tough is that you did not use the native 24p option, right? Are you going to use it in the next sample footages as tester13 suggested?

Great job!!

Thanks a lot, Gunther
 
What is the level of risk in using this new patch? I have a very important shoot for a short that I have been working on for a long time and the extra quality would be appreciated, but I would hate to brick my camera for unseen reasons. I know you can't give us a guarantee, but maybe a clear statement of the risk involved in applying just the high bitrate AVCHD patch so I can make a good decision.

Download ptool and see hints for each patch.
All green is very safe.
All yellow is also tested, but not in good working form.
Very risky patches is marked in red, currently we don't have such patches.

It was native 24p footage...

Thanks for your fast answer. I dropped it into a 23.976 1080p timeline and it showed the same 24p-in-a-60i wrapper behaviour like the original GH1 footage.

I downloaded some native 24p footage from Car3o as well and this was "real" 24p.

Strange ... Anyway, things like that will get sorted out. Thanks for testing.
 
Here.. Just put the numbers from the vimeo link between the vimeo tags in the post.
:Drogar-BigGrin(DBG)

I just downloaded this and it looks grand. I still see very slight mud in the darker areas between the flowers but it's a whole lot better than you'd normally get!
 
Strange... Because in after effects shows 23,986 and I don't have any problems...
No double speed play in players as tester13 reported...
I'll check again...

In VLC the video seems to play at normal speed but it's reported as 47.9fps.
