Title: Canon 6D Raw Video Noise Moire and artifacts
Post by: Lakwaun on February 08, 2016, 11:45:29 PM
My SD card on my Canon 6D can record at 1280x720 30fps but when I scale it up which is to 133% in premiere I get more noise, moire & artifact issues. is this normal? Does it have something to do with the 60fps moire issues it have since im recording in the same frame size? Should I just record on the 960x420 I think it is then upscale?

Also is it me or does MLV raw 1.0 work better then 2.0 beside the fact that you can record audio?

Hey Lakwaun,

     Can you try editing in a 720p timeline, and exporting as 1080p? Are the moire and artifacts still there? You might be able to purchase a used VAF-6D on Ebay to eliminate aliasing and moire.

The simple answer for me atleast is to buy a 5D3 for RAW video.

Upscaling from 720 to 1080 is a lot.
you might want to experiment with higher resolutions and limited recording times.
Like 1600x900.
Maybe even change the aspect ratio to 1/2.39 instead of 16:9.
I have a 6d and use 1728 x 720 resolution a lot, gives you about 10 seconds at 30fps.
Upscales really nice to 1920x800 resolution.

Also, moire/aliasing is bad on the 6d, same as most Canons because of the lineskipping.
But if you use raw recording and export to raw dng files, you can fix a lot with the right raw editor.
Watch what the Free/Opensource raw editor can do with Raw dng files from the 6d

720p is not usable on 6D with most the wide and middle wide shots. in RAW it gets even worse.

I think topicstarter means 720p in normal 1080 mode.
So normal 1080 mode on the canon 6d in combination with magic lantern raw recording, resolution settings for raw recording 1280 x 720 (raw recording crop within the raw menu).
This mode is really usable.

The fast 50/60fps 720p mode is indeed worse.
But still, with a conversion to DNG files and the right raw editor tools, decent results are possible.
