I’d like to make a slit-scan image with a Canon 5D Mark II running Magic Lantern. I know Magic Lantern has had slit-scan and silent picture features, and I’ve seen low-resolution examples, but I’m specifically looking for a high-resolution result. Is this possible directly in Magic Lantern, or is there another workable method using DSLR footage and post-processing?

In previous versions of ML this function was present for photo taking as well. In Silent Picture mode it would read out the Liveview frame line by line. This does mean that you were still limited to 1720x974 (scroll down to Silent Picture / Silent Pic HiRes / Slit-scan Pic).
However I see in the change log that this feature is removed from ML in March 2012 and that you are left with the video method + frame grabbing + still a low resolution.
I think the conclusion is that you can't take a high res slit-scan photo with ML.

Not really. Based on the available Magic Lantern features discussed, you can’t make a truly high-resolution slit-scan still directly in Magic Lantern on the 5D Mark II.
Earlier Magic Lantern builds had a slit-scan option tied to Silent Picture / Live View readout, but it was limited to Live View resolution (around 1720×974), not full still-photo resolution. That feature was later removed, leaving mainly a video-based workflow.
So the practical answer is:
- Magic Lantern: not suitable for high-resolution slit-scan stills directly
- Best workaround: record video with the DSLR, then create the slit-scan effect in post
A common post-processing approach is to use a time-based compositing effect such as Time Displacement in After Effects, or similar slit-scan techniques in other editing software. This can produce slit-scan images or video, but the final resolution is limited by your source video resolution rather than the camera’s full still-image resolution.
