GF2 100Mbit Stable

@driftwood's 24p has 154Mbps bitrate. That is 154 / 24 = 6.4Mb per I-frame.

GF2 has 1080p30. Let's say infra-frame patch’s I-frame target size is 6.4Mb where the 32Mbps AQ4 GOP-15 already gives such I-frame size. Then intra-frame patch would require 192Mbps bitrate. Also we wanna see improvement in image quality. Gotta achieve AQ3, AQ4, or quantizer setting lower than 22.

Frankly good image quality intra-frame patch for GF2 seems like an impossible goal. I will be happy to be wrong if someone can prove me otherwise :)

More realistic goal would be GOP-6 for better low lighting performance... if GF2 shows similar noise pattern as GH2. That is finer noise grain at higher bitrate. GOP-6 30p consists of 5 I-frames, 20 B-frames, and 5 P-frames. Let's say average size of B-frame and P-frame is 1/3. Then overall bitrate for GOP-6 would be around 70Mbps where @lpowell's flow motion patch has 75Mbps for HBR mode.

If someone can find such setting, GF2 will kick ass where it's already good at 32Mbps :)

Last settings: Ai mode shut down on video rec?Blue light are off automaticaly. Is it normal? Video really freezing on vlc - media player and video editor magix works fine.

This thread is about finding good quality stable setting. These are the steps to take.

1. Install the 32Mbps patch. Reset all camera settings.

2. Do the codec stress testing for 1080i60 FSH mode on the provided charts.

3. Analyze the mts files using GH13 Stream Parser. Report whether it’s success or failure in the proper format. Upload your patch setting if different from the 32Mbps patch. Upload screen capture of the Stream Parser app.

4. Go out. Start recording. Go through the previous step. See if there’s any noticeable pattern or issue. Report.

5. Start tweaking the settings. Go through the steps 3 and 4.

The last step would be for more advanced testers. Frankly I’m not an advanced tester. I did what I can from step 1 to step 4, and I didn’t see any issue. But that’s just me. More people would be nice.

For those skipping straight to gop-1 or high bitrate, good luck.

Nick, did you get your GF2? An army of GF2 users are waiting for you ;)

@alexufo

The patch is missing a setting for 1080i50. Look for frame buffer size section. Double the value of 1080i50 FB1 from its default.

The patch has 1080i60 FB1 doubled, and it's not crashing :)

You told me FB2 would be calculated automatically.

The patch has 1080i60 FB1 doubled.

I asked for any reason to do it. As I don't know any.

Vitaliy, you asked me why FB2 is set, not FB1.

done

I am stupid! now 1:00 am and i very want to sleep) I can't Delete-replace any files from my post upper - get this. 22 min recording < 4GB - good flying)

last stable GF2 (IMHO)

just wondering is people can load up their Bin files to let us test out.. some of us don't understand all this talk.. thanks.. =)

Where is the bitrate adjustment on the Ptool?
