Title: RBG Dots Help.
Post by: papasapien on December 23, 2017, 10:46:01 PM
hello i noticed when i record RAW that if i go to a higher iso than 100 (ive only tested 100 and 800) i have this layer of dots on my video. i know if i apply chroma smoothing these dots will go away. but i was wondering if thats the only option, as chroma smoothing lowers video quality. is there anything i can do to prevent this? or do i just have to deal with it? lol
(btw im using the version of magic lantern with loseless video & sound.)

You forgot to write which camera you use and which programs. But I think these dots are focus pixels. Try to fix focus pixels with the mlv converter tool you use and it will be fine (mlv_dump, MLVFS and MLV App can do this, maybe many others too).

sorry, I am using a canon 700D. and i am converting on the fly using MLVFS.
i dont see a fix focus pixel option in MLVFS. only thing similar is "bad pixel fix"

Right, MLVFS does only bad pixel fix, see it. Then try another tool.

Hehe, they could be everywhere to cause your eyestrain :P.
MLVFS corrects those focus dots according to map (.fpm) files.

Run the command like this:
Code: [Select]
mlv_dump -v Your700D.mlv > Your700D.log

Then upload this log somewhere and give a link.

Edit: if you can't do this just upload this MLV somewhere.

Looks like there were some changes that are causing problems with MLVFS. Are you using 12bit or 10bit?
