Blackout-Powell Native 24p Patch - GH1 FTW!!!

id changed both the 1080 & 720 GOP to 15, just ran the amended patch with 720p @ GOP 12 and now it looks like the GH13 i know and love :smile:

as always very grateful for your help & knowledge (or as we say in scotland cheers PAL) i look forward to the next instalment of the patch.

will post some footage & findings in the GH13 footage section later 2day.

By some strange method.... my clock seems to actually be accurate.... I have no idea why... this is with the 32 gig transcend class 10 card..
in theory it should be screwy and be of but perhaps that is only while recording.. after recording I think it actually checks the card space again.... but... if it is checking it for the new hacked avg rate or still 17mbit I don't know. I have been fine with 32 gig cards and shot about 3 hours or more of material...

Interesting----is there something different in your settings? Do you have less than an hour remaining on your card so the countdown clock shows seconds instead of minutes, and shooting at F8?
Supercam! Or maybe its the card, I don't have the supercard. Do you have a slower card to test if it is the card? Tx.
 
With the anamorphic mjpeg format, what are the correct settings for 'interpret footage' in after effects (CS5) if footage is shot without an anamorphic lens? All the options listed seem to stretch the image horizontally even more (except the D1/DV NTSC option)
 
I think what you do is stretch the 1920x720 to 1920x1080. Stop there if you want full HD. Crop the 1920x1080 down to 1920x810 if you want the 23.5:1 aspect raio. I have presets set up in MPEG Streamclip to do both stretch and crop in one step. I'm not sure how to get this done in AE. I'm sure there must be a way. Streamclip is pretty easy and it has batch processing.

edit: one way to do it in AE is to set the composition setting to 1920x810, then import your clip and drag to composition view, in the comp tab down at the bottom, right click on your clip>transform>fit to comp.

On Windows 7 Adobe CS5 installations, there is a file named "interpretation rules.txt" in this folder:

C:\Program Files\Adobe\Adobe After Effects CS5\Support Files

Add the following entry to this file:

# Blackout-Powell 1920x720 MJPEG 1.5X aspect ratio for use with non-anamorphic lens
1920, 720, 30, *, * ~ 1280/1920/"1.5x Non-anamorphic 1920x720", F, *, *, *, *
With this script, After Effects CS5 will automatically detect the 1.5x aspect ratio of any MJPEG 1920x720 file, regardless of whether it was shot with an anamorphic lens or not. It will then automatically interpret the footage with a 0.67 aspect ratio, which will produce the correct dimensions for a non-anamorphic lens. (If you actually are shooting with a 1.5x anamorphic lens, you'll want to use the footage directly with a square pixel interpretation.)

There's one little glitch, however, which can be easily fixed. After Effects applies the interpreted footage's aspect ratio as a horizontal scaling factor only. In this case, it will leave the 720-pixel frame height unchanged, and scale the 1920-pixel frame width down to 1280 pixels. If you drag the footage into a 1920x1080 composition, it will remain scaled down to 1280x720. You can then right-click on the composition timeline, and select "Transform/Fit to Comp" to have After Effects scale the footage back up to 1920x1080. This is all done inside AE using 32-bit precision, so the image quality isn't degraded by the scaling.

Hi lpowell,

I'm curious, what is the difference between the anamorphic hack to a screen plastic protector with marks on top and bottom?
I saw a thread where they have an image and you upload it to the camera and make marks on a plastic protector on top and bottom.
You then frame inside the center and crop the top and bottom to your editing software to have black bars for anamorphic ratio.

Mind you that I do not have an anamorphic lens. I just crop top and bottom. With this I can shoot 720 60p and AVCHD and not restricted to mjpeg.
I have been doing it this way so I am curious if there is a benefit of having the mjpeg hack installed to my GH13.
I'm currently using the reliable hack and happy ever since.
Thanks and appreciate all your contribution to the community. :)

With the 1.5x anamorphic MJPEG mode in the Blackout-Powell Native 24p Patch, there are three main advantages over shooting in AVCHD FHD mode:

1. MJPEG mode shows you the exact video frame size on the camera's LCD, eliminating the need to estimate your widescreen cropping.
2. The MJPEG HD patch records in 4:2:2 color depth, providing 720 lines of chroma resolution versus 540 lines in AVCHD FHD mode.
3. With no MJPEG post-processing required, no bits are wasted on encoding upper and lower margins that will be cropped out later.
 
Thanks lpowell and ehr. I use a mac but the scripting is the same. The conversion to 0.67 pixel aspect ratio stretches the footage correctly, but it ends up looking like plain vanilla 1080p. No black bars when viewing full screen, similar to lpowell's footage, but different to ehr's which looks more like the cinemascope effect associated with widescreen cinema.

I think it's amazing you can get that output out of a GF1

The new 1920x720 422 patch works on the gf1. :love4:

here is a sample video: http://www.vimeo.com/22503789

gf1, new anamorphic patch, century optics anamorphic adapter 37mm verison, panasonic 14-42, magic bullet looks.

looks very good! What focal length are you using? I have a 14-45mm, with the Century Optics 37mm, it only works about halfway zoomed in at f.4.8 mark. Other than that, it vignettes.
 
thanks.

it works from 35-42mm with no vignetting. The 58mm version would probably work better with the 14-42, and I'm thinking the 14-45 too, but I have never tried one. So far I've tried the century 37mm with a 20mm pancake, the 14-42, a minolta md 28 and 50. Of all those I like the adapter + minolta md 50mm best.
 
thanks ehr. I have a Contax/Yashica 50mm that works well with the CO 37mm adapter. Also those cheap CCTV lenses have a 36-37mm thread, although they are known to be soft on the edges unless stopped down.
 
Hi! I'm a newbie for the hack. So I have a hackable GH1 and I today got a class 10 memory card, so I'm ready to go. What I did:
- Downloaded Panasonic firmware 1.3
- Installed PTool3d and Blackout-Powell patch to the same directory
- Started the tool; loaded the firmware to the tool
(The instructions in the first page said that settings are loaded under "B" button. Do I need to set any options on/off??? I didn't do that...)
- Saved the firmware (GH__133.bin)
- Copied the firmware to the memory card, turned the camera on, pushed play, firmware update started
- Checked the firmware version - it says 0.0

Is there an easy way to know if the hack and Blackout-Powell Native 24p settings are working?
Windows 7 claims that total bitrate for MOV-files is 25498 kbps (MPEG HD mode) and 13246 kbps for MTS files (AVCHD FHD mode)

Yes your version number confirms a successful hack attempt

If you performed those necessary steps without modifying any of the options yourself, the firmware version number 0.0 definitely says "something has changed" in the firmware between loading it into PTool and saving it and applying it to the camera. This should also mean that all settings of the button you pressed are applied as well. Hence, this hack attempt has been successful and the settings should be effective.

You may try to shoot some detailed scenes and analyse the clip by using Stream Parser to be found on one of these forums. This will show and tell you the exact bitrates achieved.
 
No, those instructions will not install the Blackout-Powell Native 24p Patch. To do so, download the zipped patch file from the link in the first post of this thread. Unzip the patch INI file into the same folder as PTool 3.51d. Then launch PTool and load the Panasonic firmware for your camera. You can then simply click the "B" button in the lower half of the main PTool window to patch the firmware with the complete Blackout-Powell Native 24p Patch. After doing so, click the Save Firmware button to save a copy of the patched firmware BIN file on your computer. Copy this firmware BIN file to the root folder of an SD card, and use it to update the firmware on your camera.

I did all that and recorded in avchd mode (sh) and got 60p.

does 24p only operate in fhd mode?
 
lpowell said:
That's right, for 24p you must record in NTSC FHD mode. However, if you switch the camera to PAL mode, FHD mode will record in 25p.

Thank you.

By the way - can you suggest any reliable class 10 cards or variations (class 6). I'm not having much luck with ridata and transcend.
