Earthquake shaking in the high-resolution modes of the EOS-M and 100DYesterday, I decided to film a few timelapses with the EOS-M at low frame rates (0,5 to 2 fps) using the Full Sensor Readout mode at 1736x2928 and the 4k (4080x2296) crop mode (1:1) at 12 bits lossless. When I came back home, processed the footage with MLVApp and exported it at 24 fps, I was shocked. It was entirely ruined by horizontal earthquake shaking, as we know it from the 7D before Dfort successfully managed to fix it in his latest experimental builds. Initially, I thought, it was the wind causing the shake and my tripod was not stable enough but then I shot another test in my apartment and the shaking is still there.
What happens is that the image shifts horizontally by a few dozens of pixels back and forth from frame to frame. This shift is also visible on the preview screen image while recording if there is a vertical contrasty edge in the scene. This edge also moves back and forth every time the screen refreshes. Fortunately, I was able to fix my footage by applying stabilization to it in Resolve. If filming at higher fps (14 to 24 fps) the shaking does not seem to be so obvious and is hard to notice but stabilization makes it smoother meaning that it is probably there even at higher frame rates.
I used the latest 29-th of April experimental build for the 2.0.2 FW version on the EOS-M, installed on the recommended 64 GB SanDisc Pro SD card but I found some unprocessed timelapse footage shot on the previous January 10-th, 2020 build and shaking is there too.
Here are my settings:
Shutter speed in the Canon Menu: 1/30 sec.
Video tab settings in the ML menu:
======================
presets: 5k anamorphic rewired
RAW video: ON 1736x2928 (16:9 ratio set in the submenu, Preview: Framing)
bit depth: 12 bit
shutter range: Full range
FPS override: 1 fps (actual shutter speed was 1 sec. at this setting)
everything else set to OFF
I used the same settings also with the 4k crop (1:1) mode, except for Presets.
===================================================
Here are a few samples before and after MLVApp conversion that illustrate the shaking phenomenon. A stabilized sample is also included:

Hopefully, it's an easy fix.
