I'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:
improvement for 5d3 will be a little revolution because 5D3 is far better in terme of quality. It will not only be a cheap camera to achieve raw footages but a real cinematique camera for professionnal work.
"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.
Here is another Batch of clips, mostly 14bits like you requested: http://bit.ly/3X7hATq
Clips 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.
All 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.
