Here is an untouched DNG Sequence (Heavily Compressed With 7Zip) directly from the 2.1, that shows this Banding i talked about above in Motion. Watch for the Reflection on the Hammer and how it affects the Background. Shot at 0db 1kfps, 180° on an Schneider-Kreuznach Tele-Xenar 75mm/2.8 (was a bit stopped down, not exactly sure where i put the Apperture at...). This Short bit of Footage also shows Ghosting, where the Hammer Moves Fast, there is a "Ghost" Exposure of the Overexposed Highlight Visible, which disappears, when it suddenly stops. The Ghosting was allready there in the Previous Version, and wasnt really a Problem Ever for me, but still wanted to point it out, as i now finaly have footage which shows it very well; but the "Horizontal Banding" isnt that nice, and i dont remember it beeing that visible bevore.
Ran into this Ghosting issue again last Weekend, when i had a Shoot, where we Tried to Shoot a Water Drop Silhouette on a Black Background. There it was a pretty big Problem.
Requirements for the Final Shot were a Black Seamless Background, and only the Drop (/spot where the Drop hits the Surface/ resulting Waves) or its silhouette visible.
Did a Proof of Concept shot on the 0.6.0 Firmware @1kfps, and it just looked completely unusable, immediately switched to 0.5.1Unstable, and it was about as bad.
Ghosting was about the same or a bit less on the Unstable 5.1 Build, but at least the banding was way less visible.
Ghosting seems to become really nasty and bad, if Image is basically solid Black and some Overexposed or at least extremely bright spots moving very fast relative in comparison to Framerate (what that shot was all about).
Did the Rest of that shoot on the 5.1 Unstable Firmware, and eventually switched to 2.1kfps, as Motion blur was a bit much anyways, where it was still noticeable there, but way less prominent/ distracting.
As Ghosting seems to be about the Same on both Versions and thus still relevant, i thought i might as well share it here for future improvement.
.
Attached is an Render of the First Proof-Of-Concept Shot i did (sadly cant share any final Shots here, lighting was changed a bit later) on 5.1 Unstable, and some Untouched DNG Frames from the Same Shot.
For the Render i didnt even Bother to do any further editing, grading or denoising, its mostly just an DNG-Conversion to MP4, to be small enough to be posted here as an Entire Sequence.
.
Settings Must have been 1000fps/0dB and something between 180° and 130° Shutter, but i didnt take any notes about it that day, so cant say for sure about the Shutter Speed.
