What is the minimum bitrate? For example, shooting a blank wall?

no crashes or freezes yet..Thanks for putting this to the test, zigizigi. Did the camera save an MTS file when the recording failed? If so, I'd be very interested to analyze a copy of the original video file.Failed at 11:57 while shooting this cars'n'trees test scene off tripod

Freeze on record with these settings
Freeze on record with these settings
Just tried these settings and ran into some issues that I thought I'd report in.
First off, I've been following these threads for weeks now and finally did the hack for the first time today. I'm familiar with software testing and troubleshooting, so I tried to be as methodical as possible. I'm using a GH1 with stock 14-140 lens and a brand new 8GB SanDisk Extreme Class 10 card. Using Wined pTool v40d. For AVCHD settings I set camera to FHD. I also formatted the card after firmware update.
1st run: Used Stable 35Mbps MJPEG patch referenced in this thread along with 40Mbps AVCHD settings.
Results: MJPEG recorded with no issues, When record button pressed for AVCHD recording, camera freezes, had to remove battery. Tried multiple times with same results.
2nd run: Reloaded GH1__132, modified only AVCHD setting with 40Mbps settings. I'm thinking maybe too many mods, so simplify.
Results: Same thing, freeze after record button pushed.
3rd run: Restored to GH1__132, just making sure I'm doing the update correctly.
Results: Back to normal, everything works fine.
4th run: Used "C" settings as directed in pTool. No mods to MJPEG settings. Before posting to this thread, I wanted to make sure that the issue was related to the new settings and not something else.
Results: Camera recorded fine, no issues with freezing.
Conclusion: My camera doesn't like these settings or I'm missing something (which is most likely the case). I did not change anything on the Video Bitrate H or L or Limiting Bitrate. Is this part of the problem?
Thanks for your help. I'm very interested in using the reliable oriented settings and my plan is to use them on my gigs to report back with "real world" usage. When you're getting paid, shoots have to go well, so I want to help out with that aspect of the hack research.

If you see a patch for "Limiting Bitrate" then you don't have the latest version of PTool.
Unfortunately, the last few updates to PTool have been marked with the same version number, and the best way to be sure you have the latest version of PTool is to download it again:

I just bought a silicon power card and it failed most tests -worse results than my Panasonic class 6 cards
Here are two full-frame thumbnails from videos taken with the 40Mbps AVCHD High Reliability Patch. Beneath each thumbnail I've included a screenshot of the GH13 Stream Parser display of the running bitrate of the 8-second video it was exported from.
Hillside Landscape (~40Mbps)
Lux Mausoleum (~20Mbps)

Tested at blank wall ... ~ 19Mbps :smile:
I redid my test today with SanDisk Extreme 16gb 30MB/s class 10
Fails after 5-10 seconds. The maximum I could record was 50 sec. While my today's attempt with Silicon Power Card was more successful: it recorded 23 min before it hit the 3.99Gb wall. Go figure.
[Settings]
Version increment=5
Prevent version compare=Checked
Third-party battery=Checked
All Interface Languages=Checked
PAL<->NTSC Menu=Checked
Video Bitrate FHD/SH=41000000
Overall Bitrate=43000000
Preset bitrate=180
Preset bitrate 2=180
What is left to blame? Using PAL hack on a native NTSC camera?
