I have an upcoming project in PAL. I am looking for a stable setting for 720 50p but I can't find any consensus.
The above discussion is way over my head no matter how hard I try to understand it. I just want a stable setting where stability is priority over IQ. What would you suggest?
(I will be using SanDisk extreme class 10. And yes, I want to be able to playback the clip in camera)
@driftwood Today my friend gave me other options. They can set the bitrate to 50 Mbps and GOP6 or GOP12. And everything seems to be working, but ... if you shoot trees, Stream Parser show jumps (Hard 1). How to fix it? Here is the configuration file, 40 Mbps, Gop12, AQ2.
I think it all depends on this part:
--- Video Bitrate 24H ADD = 50 million Video buffer = 0x2800000 Video buffer 24p = 0x2800000 Quantizer for 1080 modes = 17 Quantizer for 720 modes = 17 Muxer buffer for 24p = 33,165,824 Muxer buffer for other modes = 19582912 1080p24 High Top Setting = 52 209 1080p24 High Bottom Setting = 40 846 1080p24 Low Top Setting = 38 589 1080p24 Low Bottom Setting = 34 900 Other Modes Top Setting = 49 900 Other Modes Bottom Setting = 39 100 ---
My card can not write with such speed, GH2 dies in all modes :( I can shoot only a table, chair, wall ...
Report Stream Parser to be the same as yours. Think it native 25p :) But if you insert it into Sony Vegas, then shows the first 3 frames ... and nothing else
@AKED@Botvinic This is probably a false positive, but run this test very quickly for me and check it out. Read the instructions within the settings. ignore the 720p stuff for now and other settings. Test 1080 FSH and see what happens! Make sure you test at 50, 100, 125, 200 shutter, then do other shutter tests. Keep iso down low for now. NOTE: this is nowhere near a final setting, Im much further down the line but just want you guys to check this earlier setting. UPDATE: Now run another test and uncheck the encoder 720p settings. It appears its all about the video buffer being 3000000 :-)
@AKED dunno if youre up and about but could you test something for me. Can you put Encoder Setting 1 720p = 1 and Encoder Setting 2 720p = 1 (I know it sounds odd) and load the firmware. Record a 1080i FSH recording and tell me if its 25p or 25p in a 50 wrapper. thnks
I know. Has that to do with the B-frames? And thanks for your testing. It is great that there are peopel like you, who know what they are doing when they test and then share their results with the group. Thank you.
In the beginning, ther was much talk about the possibility of putting B-frames in the 720 mode. As far as I remember it also worked. Now in the last weeks there was nothing to read about tis. Not important any more?
I have had problems in setting 44M (720 34M, Gop24. AQ2) yesterday again, but I've formatted my card on the computer and everything works again.
After formatting the card 38 Mb are working. But on very complex scenes GH2 dies, such as trees in full screen. I made myself are settings: 38 Mbps - for SH mode, 30 Mbps for the H mode. Gop 24, AQ2
