MJPEG 70mbits+ 1080p settings

Do we have all the settings in the new PTool 3.36 update? I can't find a few of them, are they called something else now?

Pappas Settings:
MJPEG 1280m Encoder settings.
MJPEG 1280p width - input 1440
MJPEG 1280p height - input 1080
MJPEG 1280p Encoder width - input 2096
MJPEG 1280p Encoder buffer - input 4821120
QUALITY SETTINGS [ 384, 330, 300, 276 ]
TABLE SETTINGS [ 24, 24, 24, 24

Where do Encoder width & buffer go?

PTool 3.36v2:

I can confirm that your settings with the squash works on verbatim class 6 card...no write errors recorded for 3 minutes...with bitrate peaking at 69mb....seems super stable!

Great report back. I'm gonna try it out today, just not expecting playback in camera.

Really wish I had lens adapters right now, stuck with the Kit Lens currently. Doh.

Well the video in this Hi-Mbit rate mode is recorded squeezed like HDCAM 1440X1080. However I'm guessing your asking for selecting a 1:1 use of the sensor to match 2x anamorphic lenses. It doesn't do that. That would be a cool option though.

Probably a long shot.. but concerning 2x anamorphic shooting, do think it'd be possible to hack the MJPEG 4:3 VGA mode with a higher bitrate (or does the current patch do this already?) and a frame size of 1440x1080? This mode uses the full 13mm height of the chip and would also eliminate most image cropping in post.

Either way, it's felt like Christmas morning for the past 3 days on here. Amazing work everyone!

Hey! This is a GREAT idea, actually. I dunno if tester can actually do it, but at the rate he's going, I wouldn't even put it past him.

Throw this request in the main thread to see if it's possible or direct him to this post.
 
Bloody fantastic idea :)

I would love 4x3 mode for its own sake, as well as with anamorphics in front. Academy ratio's no slouch!

Yeah there's no playback in camera. Bit rate to big I guess, or not. However you can see the thumbnails and zoom into them, as well check histogram etc.

*****Just to note. As with 1080 AVCHD you can not shoot below 1/30th in 1080P. If you do,
it either stops or freezes the camera.

If you shoot at 720 in the 80Mbits mode you can shoot at all shutter speeds with no issue.



Shooting 720P at 80mbits is cool, and I do recommend you try it. That's a lot of data rate to be thrown at 720P. It would be kinda of like 140mbits at 1080 sampling. HDCAM was 144Mbits for example at 1080.

Blowup test of 720P

On the front page I list what you need to do to shoot at 720P 80Mbits.

Looking back at footage. The 80Mbits 720P has a definite awesome look to it, you can tell that it is having a lot of Mbits thrown at it. It's like S16 look with digital noiseless performance.


On this front page I will post findings from reports back. So be sure to report things you experience.

Did some tests today, using Pappas MJPEG settings and jobless "easy" settings with a Buffalo Class 6 card. Amazing! Everything is so much sharper. I tried to do some before and after tests, including 200% crops etc...:

It was pretty difficult to get this side by side comparison. Download the file link to get best results when viewing.

I think even resolution has increased, as those "islands of unsharpness" have gone which were there before, even on static shots

Great thanks to tester13!!!

I'm thinking of getting a GH1 now that I've seen this hack and I have just a couple of questions:

1.) In that software where you modify the firmware, I saw that you can edit the GOP, does this mean we could create an intra-frame codec or is the MJPEG already an intra-frame codec?

2.) Is there a way to increase the color sampling from 4:2:0 to 4:2:2 or even 4:4:4?

3.) What is the reason we can't get up to 100mb/sec or higher? Is it the SD cards, the processor in the camera?

4.) Is there any possible way to "capture" the stream of information going to the SD card and instead, have it route to a hard drive or other recording medium?
 
1) MJPG is intraframe. The GH1 offers both.
2) On MJPG, tester13's already found a way to make it go 4:2:2, although that hasn't been released yet
3) Don't know. Could be both. Technically a Class 10 card only has to support 80mbps/sec.
4) Don't know. If there was an SDHC-to-CF adapter, you might be able to get higher speeds. But you'd have to modify the camera because you can't record with the card door open.
 
1.) Thanks. I remember you saying that a non modified GH1 really worked better shooting the AVCHD codec, but now that you can achieve higher data rates, I guess this becomes the better codec.
2.) If he can make it go 4:2:2, maybe 4:4:4 shouldn't be far off.
3 & 4.) What about wiring an SD card to a CF card reader/writer and just drilling a hole in the card door to allow the cable through. This would be a pretty delicate camera then, but would it allow for higher data transfer speeds?

Also, how do the movie files appear on the card, .MOV?

Excellent report GMC. From what I can see in your examples the patched AVCHD seems to show more detail than the patched MJPEG. Both are better than your unpatched examples, though I find the AVCHD improvements more obvious than the MJPEG improvements. Either way, I really like how you've presented it here. Thanks!

3). from what i've read from tester, the reason is the SD controller on the camera is limited to 80mbit/sec
