It's a known issue. Improvements were made on the HPX-370. You have to play with the settings that appeal to you. Save it to the SD card and your good to go.

Hi,

Just looked at this list of Scene files and the only issue I have is that the DRS seems to be programmed in to either a 1 or a 3 level. DRS is a feature that when used when needed provides an excellent means of controlling a very wide dynamic range. Used when not needed, will result in noisy pictures. The circuit is always in comparison mode, dividing and conquering over 4028 segments on every frame. If you need it you'll be happy you have it. If you leave it on for normal shooting beware that you maybe undermining your desired noise floor.

Yes I know it is on a User button to activate, but you need to know how this works and use accordingly.

Best,

Jan

Hello Jan,


It is just frustrating that I had spent $8000 on this camera to have all these issues, I had purchased the camera in the US and I live in Ecuador now, I will try the settings provided on this forum.


Thanks.

Hello David,


I am confused on the settings that does not specify the value (-) or (+), example:


SCENE NAME :DANGER
00005000: 1 ; VFR : OFF
00005001: 24 ; FRAME RATE: 24 FRAME
00005002: 01AB0708 ; (SYNCHRO SCAN):
00005003: 6 ; DETAIL LEVEL: -2
00005004: 8 ; V DETAIL LEVEL: 0
00005005: 13 ; DETAIL CORING : 5 THIS SHOULD BE (-) OR (+)??.
00005006: 11 ; CHROMA LEVEL: 3
00005007: 8 ; CHROMA PHASE: 0
00005008: 8 ; COLOR TEMP Ach: 0
00005009: 8 ; COLOR TEMP Bch: 0
0000500A: 122 ; MASTER PED: -6
0000500B: 16 ; A.IRIS LEVEL: 0
0000500C: 0 ; DRS EFFECT: 1
0000500D: 4 ; GAMMA : B.PRESS
0000500E: 2 ; KNEE: LOW
0000500F: 0 ; MATRIX: NORM1
00005010: 0 ; SKIN TONE DTL : ON
00005011: 1 ; V DETAIL FREQ : MID
