Quote from: gabriielangel on February 06, 2023, 07:53:12 AMHere are more MLV files you can use to check the effects on hair, fur, colors and textures.Some of the dirty pixels trapped in the thin strands of hair can be reduced by playing with CA Correction and CA Desaturate, but not all.Please Download ASAP, I will remove tomorrow as my drive is very full http://bit.ly/3jvWL6c
Quote from: ML700D on February 06, 2023, 08:10:27 AMto save space I think you just have to cut in out about few frames in mlvapp then export to mlv file again as a sample file..but I don't know if it makes any different in quality.
Quote from: gabriielangel on February 06, 2023, 08:53:29 AMI cut each file to 2 seconds like you said (MLV Fast Pass), to give enough time to see flicker and aliasing artifacts, if any. Those files are just huge by file transfer standards
Quote from: Danne on February 06, 2023, 09:13:05 AMAll of the provided clips looks good when processed. If we get back to this clip:M04-1236-BldFeb042023am.MLV it will give a subtle flicker. It´s 10bit though. Is it possible to record a similar clip at 14bit? Dual iso is strongest when 14bit. 10bit not so useful imo.
Quote from: gabriielangel on February 07, 2023, 01:53:49 AMHere is another Batch of clips, mostly 14bits like you requested: http://bit.ly/3X7hATqClips were all recorded with Histogram showing 0.5.Pay particular attention to M06-1306. I included a MLVApp receipt which will emphasize the point of interest.One has to be careful with exposure, as when in dual Iso mode, False colors and Histogram are not spot on (Those register a lot more headroom than what is actually available). 14bits is more forgiving, but I often clipped the snow outside when monitoring with those. I got good recordings when maximizing at both the base and recovering ISO individually, in single ISO mode and then enabled dualISO.If you look at the waveform monitor in MlvApp, you can sometimes see that the absolute level is below clipping, but the shape of the drawing (Flat Top) suggests otherwise.Recorded with 2023Feb06 Build.
Quote from: Danne on February 07, 2023, 04:53:29 AM"Pay particular attention to M06-1306"If you change fps to 20 fps, what do you expect to happen? Also height is altered?My fix was about finetuning fps so your modification breaks the fix. It is very easy to see what happens by viewing the scanlines in dual iso output. In your example the lines are creeping around, if you look at the other clips output are showing calm, static lines.If you intend to alter fps, at least find sweet spot and achieve static preview on your camera before recording.In HD1080p dualiso won´t be flicker free as it runs native canon fps. Might fix this but dualiso with 3x3 looks like garbage mostly anyway.Added 1736x2180 pixel map and uploaded an eosm build with the new resolution.
Quote from: iaburn on February 06, 2023, 07:58:06 PMI've updated a branch that applies twice the focus pixel fix for dual ISO, the second one after the dual ISO processing, like a non-dual ISO video, and the results are much better on my tests. More obvious on binning modes due to larger stretched pixels, but less artifacts in all modes.A comparison, better download and switch from one to another:No focus pixels fix:Normal fix, the current one:Double fix:
Quote from: Danne on February 07, 2023, 06:02:36 AMThat particular preset I missed to fine tune. In general I will focus mainly on the top presets in the tap display list. Bottom ones, not so much, used too little.You can easily spot if output looks wrong now I guess.
Quote from: iaburn on February 19, 2023, 11:21:28 PMI've done a small change on my fork and it seems to help with flickering in some clips (not all)!The problematic video from this post it's muuuch better now.Before, this video was showing different issues when Alias Map or Fullres Blending were active, but now looks good when "horizontal stripes fix" is enabled (finally found a use for this fix )Did a windows build in case someone wants to try: https://mega.nz/file/A1tiTASK#OK46h1pPjzsJDILuHyoGQNbLWM6VVm0u7lUfm41CE1A

Using the "horizontal stripes fix" is an option but the result is not perfect, needs more work...
Quote from: ML700D on February 20, 2023, 09:32:27 AMnice.. dual iso flicker disappear but there is horizontal stripes flicker instead
