Im trying to render an HDR video using dual ISO in ML (100/1600) and MLV app.

Here are my settings in MLV App


This is what I get with Dual ISO ON in MLV App :

This is what I get with Dual ISO OFF in MLV App :

Could you please let me know what Ive done wrong ?

HDR isn't Dual ISO

Just Enable "HDR blending" in MLVApp export settings:
33" border="0

You should be fine.


You mix up HDR Recording and Dual ISO recording.

HDR Recording alternates between 100 and 1600 every other frame e.g. the flickering you are seeing. And needs to be merged/blended. Search the forum for post process of HDR.

Dual ISO records 100/1600 ISO simultaneously (every frame), but every other Pixel Row is 100,1600,100,1600 etc. And also has to be merged with Dual ISO Post Processing.
once you go raw you never go back


Thanks Kharak and theBilalFakhouri
I was indeed confused and mixed up HDR and Dual ISO.

I'm trying to film HDR for real estate. Dual ISO doesn't seem to have the dynamic range I need.

I think HDR recording should be what I need. However, every links I find for tools are dead. Ive found this video https://www.youtube.com/watch?v=5me5jEr4ldQ explaining the process. But all the links here are dead : https://wiki.magiclantern.fm/userguide#hdr-video

Where can I find the most up to date tools and workflow tutorials ?

Thanks a lot for your help
