again my error as I am shooting at 1:1 and the rail is moving forward in UM ( micro mm ) I think there is diffraction or telecentric issue.

I checked all the dngs individually and cannot see any corruption of the left side but I suspect when they are stacked there is change in the image size ( I think) .

I might try 16:9 or different ratio maybe but I am clutching at straws

That's good. Do post results you are getting. Seems like exciting footage and workflows.

The files looks ok. I wanted to check dng processing behaviour on bigger files and it works well too.
I'll send you a pm about the other query.

with the mlv_dump, what parameters would help in terms of better quality , if any , when I extracted the DNG's in yr opinion?

For 5D mark III I wouldn't mess with settings unless something seems wrong. Darkframes are always good to include.

Hi Danne

FYI: You may be interested that I get some corrupted DNGS from time to time but I am not sure the cause"

1. issue with crop rec bug? or
2. issue when files are being extracted to DNG ?
3. issue with CF card?

This folder had 353 DNGs and only 1 dng was corrupt.

cheers
Denis

I´m guessing something in camera.

Can you upload the original MLV?

Hi Alex

Well I created about 12 mlvs but no corruptions. Must be intermittent,

I am still taking MLVs and if it occurs I will provide the MLV and advise you.

Thanks for your patience

cheers

Hi Alex

I made many  mlvs last week but I am unable to recreate the DNG corruption .

I will keep checking

cheers

Hi Alex

You requested a sample MLV file . I had this issue from time to time as an intermittent problem.

I did a movie today and all 3 MLV's were corrupted, Every single DNG.

cheers
Denis

Attached is the MLV link of the corrupted file
I ran:  mlv_dump -f 2-10 -0 corrupt.mlv m24-0944.mlv

Best guess: some issue during lossless compression.

Would be great if you can find a way to reproduce it. Can you exclude this scenario?

(taking a still picture from Canon's movie mode appears to interfere with the lossless compression)

Thanks Alex.

Ah yes, I think I may have accidentally hit the Canon movie mode initially.

I will retest and get back to you.

cheers

Hi Alex

A general question.

Is it technically feasible to increase the FPS  for the current 5796x3870 @ 5fps or have we hit the 'physical' limit?

cheers
Denis
