Hi

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

Here are my settings in MLV App

Hello

HDR isn't Dual ISO

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

You should be fine.
Announcement: 100D/SL1 users:
I am willing to port the latest RAW video achievements to 100D. Check this for more info: https://www.magiclantern.fm/forum/index.php?topic=26250.msg238692#msg238692
We are almost half-way from the goal! any help from any user is appreciated.

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 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
