Shot with Canon T5i/700D utilizing Magic Lantern in-camera software.  Magic Lantern RAW 2.5k Crop Mode Module @12bit depth/lossless compression, and SUHD overclock hack.  Workflow:  MLVapp to expand individual CDNG files from .MLV container, Lightroom to color grade extracted frames, After Effects to compile into video codec, Premier Pro to edit clip length and add soundtrack.  All footage saved in uncompressed .AVI codecs whilst in Adobe, then I used AnotherGUI and FFMpeg to transcode final footage into Apple Prores 185bit format for uploading to Youtube.  I used a Newer brand slider to pan the camera, then used Warp Stabilizer in Premier Pro to smooth out panning further.   Not too bad for a $400 camera and kit lens setup.  :)

Hello,

Recently, a new module for ML appeared that facilitates RAW video recording at a dual ISO setting.  Along with a 1x3 sampling rate, among the features mentioned by the developer(s) of the module is the virtual elimination of both aliasing and moire' artifacts that have previously plagued ML RAW video recording at non 1x1 sampling rates (previously requiring crop mode recording).   My question is what ultimately is the advantage of dual ISO capability in the context of Magic Lantern use?  Is dual ISO required for the elmination of artificats and implementation of 1x3 sampling rates at non-crop modes or is dual ISO's main advantage increased dynamic range and reduction of noise in shadow detail? 


Thank you!

(Watch in 1080p mode)  Shot with Canon T5i/700D utilizing Magic Lantern camera software, Crop 4k on Steroids build, along with Danne's SUHD overclock module. Lens: Canon EF 75-300mm zoom @300mm. Shooting resolution: 2240 x 1080 @ 12 bit lossless compression. Shooting Mode: RAW Crop 2k @ 5x Liveview Crop Mode (3x effective). Workflow: MLVDump to extract individual DNG frames from .MLV archive; Adobe Lightroom to color grade frames; Adobe After Effects to compile DNG frames to encoded uncompressed .AVI file.  Adobe Premiere Pro to edit encoded .AVI file and add soundtrack, export again to uncompressed .AVI file. FFMpeg with AnotherGUI Interface Software to transcode uncompressed .AVI footage to Apple ProRes 444 format. Note: The very latest versions of Adobe software will export directly to Apple ProRes format as of December 2018. My software is older, so I must utilize the steps above.

I'm still trying to fully grasp what pixel binning is and how it relates to the final image quality when shooting ML produced video.  If I understand correctly, 1x3 binning equates to 1 out of every 3 vertical lines of resolution being imaged from the sensor whilst 3 horizontal pixels are grouped together or "binned" as 1 pixel?   Therefore, 1x1 sampling equals 1 out of 3 vertical lines being read while no horizontal pixels are being binned?   In 1:1 mode using Movie Crop mode on the 700D, this would equal vertical line skipping but no horizontal pixel binning?

In 3x3 mode, this equals no vertical line skipping whilst binning 3 horizontal pixels?   

I'm ultimately trying to understand why 1:1 mode in standard crop mode recording on the 700D virtually eliminates aliasing and moire.  Thanks so much for any insight you can give me!

Hello,

I'm currently using a Magic Lantern Crop 4k build for the EOS Rebel T5i/700D that includes options for 2K+ resolutions in 5X crop mode.  I'm trying to gain a better understanding of what full resolution liveview recording is versus crop recording?  Does full resolution liveview recording facilitate 2k+ resolutions in a full frame rather than a cropped frame liveview?   My current understanding is that for the T5i/700D, one must always be in 5x crop view mode to record in 2K+ resolution and that full frame recording in high resolution is not possible due to hardware limitations. 

I'm wondering if I misunderstanding the concepts here and that I'm not fully grasping what full resolution liveview recording is.   I would greatly appreciate any insight that could be provided, thank you!

(Watch in 1440p HD mode) This is footage was taken via Danne's experimental Magic Lantern SHD overclocking module build that includes auto-script settings for SHD write speed overclocking as well as Crop Mode 2.5K and 10-bit lossless compression format for RAW video. I utilized the freeware MLVapp program for color grading and directly exported from .MLV format to Apple Prores 444.
