current crop_rec_4k build on the experiments download page gives me pink highlights if I have any overexposed parts of the image and use 12bit lossless compression to record mlv. As soon as I set compression to 12bit lossless I also get a darkening of the live view image and any overexposed areas also show the pink highlights same as the dng from raw mlv. As soon as I half press the shutter the live view image returns to normal (no pink highlights and a brighter live view image).

I use mlvfs or mlvdump from crop_rec_4k build and then adobe camera raw to process dng

I've also tried the patch. 12bit compressed DNG look identical to 14bit and have no pink highlights when loaded in ACR or Resolve. Before the patch I was getting pink highlights in both software. I also still see the pink highlights and the image is very dark in Live View when set to 12 bit compressed (14 bit compressed looks normal).

Im so impressed with all the work you guys put in and the things you make this camera able to achieve. It amazes me that lossless mlv is working on this little camera. Im currently using raw on the 100D for some of my film pieces on my uni course.

However I've run into a problem whilst trying with the latest crop_rec_4k experimental build. I like to work in raw in Da Vinci Resolve, if I use the standard 14/12/10 bit or the 14bit lossless then everything is fine, however if is use the 12 bit / 11...8 bit lossless then I get pink, magenta colour in the highlights in the DNG files in resolve and ACR, if I under expose so there are no real highlights these aren't present.

This also shows on the display whilst previewing or recording (I also get a darkened display as mentioned in an earlier post) and if I half press the shutter display returns to normal. I've tried black/ white level settings, etc, these made no difference. The only way I could remove this colour cast in the highlights was using the reconstruct green channel option in MLV Producer, but MLV producer isn't my preferred workflow.

I'd really like to be able to use lossless and I'm just wondering if Im missing a setting somewhere on camera or in conversion software or if this is a bug. I couldn't find any info on this in any of the other topics but I could have missed something.

I'd appreciate if you enabled and pushed to bit bucket, especially if it means I'd have all the latest fixes.

I had been using the January build of the 10/12 bit module recently and everything worked fine, recorded some fantastic video with it. I decided to try the builds on the Experiments download section (including the previous versions june and 2july), if I use 10bit or 12bit mode it records to card fine but now live view freezes as soon as recording starts so no way to monitor whilst recording. 14bit mode works fine. Just wondering if anyone else has had this problem/ has a work around or if this is just a bug that needs fixing.
