I'm using quite the same workflow to save space (using ProRes4444), but I'm applying the ML Log profile instead of SLog3, as it's specifically calibrated for the 5D3 (you need then to color grade considering it's a Cineon log profile)

Last post by belalkhansocial - Yesterday at 09:06:16 PM

Been messing about with post-workflow. Having been working with Slog3 footage with Sony cameras for work, I figured let me see if that same workflow can carry over to MLV Raw

This is just a results comparison between my previous workflow using Adobe Camera Raw and my currently Slog3 workflow.

Short answer - it doesn't matter how thin or thick the cable is, you can connect whatever you want and everything will be fine.

But the camera draws some current (for example, 2 amps or more for 5D2), so if you are using an actual battery - 18650 cells or a power bank - then you may want to use thicker wires whenever possible. To minimize losses and have more efficient setup (longer battery life).
So it is good to use thick wires, but if you are powering everything from ac/dc adapter then there will be no real difference.

I say this because I used relatively thin wires with cheap case for 2x 18650, and I measured about 0.1v voltage loss, it is 200mW or more wasted. Not much, but anyway..

Camera-specific Development / Re: 200D shoots raw video

I'm curious to see if there is a visible gain or not with dual ISO on the 200D 

I now have a decent set of test files.  Sunlit window scene with shadows and a range of colours.  Shots taken in 100/100 up to 100/3200.  Three sets, exposing for ISO 100: "ETTR-ish" (about 1 stop overexposed?), 2-stops under, and 4-stops under (this one includes 100/6400).  Why under?  Because Walter took a look at the first set and said they were weird; good highlight recovery but not much change to dark areas.  So perhaps 200D prefers it the opposite way to old cams.

If you want to compare, DM me for the links.  It's about 250MB per set.

Appreciate your effort, thanks, somehow I came to simular conclusions —- I just hoped maybe the developer posted somewhere on this forum about his objectives and his progresses, and some ML hero member would recall the posts.

Guess I will skip that repo. I started playing around on my repo, will post when I have at least a PoC.

EDIT: anyone can explain gitHub-based cedricp/MLVFS commits dated Jun - Jul 2022? His work seems to be based on commit 9f81918 [May 31, 2016].

I only skimmed this, and the commit comments aren't very helpful.  Some of the work is definitely based on the bitbucket dmilligan repo.  Just copy pasted, so you lose the commit history   You will want to cross ref these two repos, I would guess.  Some of the work is similar and for the same feature: lossless MLV support.  The cedricp repo also adds cmake build support (?) and moves a bunch of files around.  Perhaps this is important, perhaps not.  No explanation is given for why this is done.

Actually properly determining what these changes do is several hours work.  I'm not volunteering, sorry!

What to explain about?
It would be great if you manage to speed up things.

Thanks Walter. I will try that.

My concern was if that it could be some kind of noise (sort of speak) in the battery current. The thinner cable is a cable for the dummy battery that i cut out and the thicker one is a cable that goes directly to a battery adapter plate that will use an NP-F battery.

What about the other option?... Connect the dummy cable, the thinner one, directly to the battery adapter plate with power connector?

Remove solder. Straighten strands. Twist both cable strands together. If unable there are 2 options:
- Remove some strands from thicker one. Then twist.
- Isolate thinner cable longer. Use thicker cable as "core" for thinner cable.

Sorry, unclear description.

You need to insert both cable ends (4 wires) to terminal screws?

Those cables need to be connected together Walter, to conform a single cable. So my concern was if it was ok to connect them since there are of different caliber.
