I see..  thanks Walter.

Benchmark ok?
Can you tell us average data rate for recording?
unstable sometimes 10 seconds and less.

Benchmark ok?
yes. and done low level format too.

hi bilal,
I just tested your latest crop mood build, all looks great!
unfortunately, I only can record highest resolution for couple seconds though. is it normal?
setting I use: all hack, sd 240Mhz others is default.(14-bit lossless, crop mode 1x1 or 1x3, etc.)
and got some issue when using 1x1 full res. in 10x mode.

nice transition! can you teach me?  :D

Wouldn't it be possible to take every other 2 rows?
With 3x3 we read the red-green row, jump 2 rows and read the green-blue row.

Cannot we read the first 2 rows (red-green and green-blue), skip 2 rows, and read again 2 rows, so we get half of the sensor?
I'm just curious if 2x2 or 1x2 binning mode is possible..what would it be like?

I don't know technically but watching your video  I like RED cam. it's more colour depth I think.

I found the ML's dual iso pdf doc on the internet that helped me to better understand the code and I finally got better results for the exposure ISO matching function. It should also be slightly faster.
For those interested the doc is here
I pushed the code on my gitub if you wanna try. It's not perfect, but it solves almost all the problematic shots.
nice finding.. I don't understand coding
I hope ML dual iso getting better next..

btw, is it for eos M user only?

I use cineon log in mlv app (color space use wide gamut like: adobe rgb, alexa wg, sony or davinci gamut) when edit using DR with default setting,  I think.. it gives better gamma and easier to grading when work in rec.709 environment.

5d3 has good sensor I think..
I like 1x1 mode because I don't need to change the focal length for my 10-18mm that gives f/4.5 better than using f/5.6 at 18mm, less blur but it's ok for me lol.
in 5:22 I don't see the problem, your image looks fine I guess?

I don't see any pink highlight clipped in mlv app, your image is good..

thanks a lot, I'll see it in mlvapp.

use 10x mode for focusing

it's ok.
I appreciate it.. thanks.

recently I migrate to resolve.. but still use the old way, mlvapp - resolve workflow lol..
btw, can I have some sample clips of your video to try?

5d3 is amazing, I think using tripod will help when shoot macro and no need software stabilization.
are you using davinci or mlvapp for grading?

General Chat / Re: BMPCC vs EOS M Dual ISO
« on: February 25, 2023, 05:36:13 AM »
5k dual iso is good..
I think bmpcc has more dr and eos M looks softer, IMO.

I've done a small change on my fork and it seems to help with flickering in some clips (not all)!
The problematic video from this post it's muuuch better now.
Before, this video was showing different issues when Alias Map or Fullres Blending were active, but now looks good when "horizontal stripes fix" is enabled (finally found a use for this fix  :D )

Did a windows build in case someone wants to try:

Edit: It seems to introduce horizontal lines where they were not present before... Using the "horizontal stripes fix" is an option but the result is not perfect, needs more work...
dual iso flicker disappear but there is horizontal stripes flicker instead

I see.. many thanks bilal!


Good samples, unfortunately the issue is coming from Dual ISO processing algorithm, not from my builds. I only tested MLVApp and there is flickering. Didn't test cr2hdr, may work better.
More likely it's something related with black level in Dual ISO processing algorithm.

Oh.. I see, thanks for explanation.

-But why you are uisng 12-bit uncompressed?

AFAIK, Dual ISO works better in 14-bit (either uncompressed or lossless), but for lower bit-depths and for Dual ISO, always use lossless, it works better than uncompressed lower bit-depths.
And that's probably because black level there is same as 14-bit lossless (maybe that's why Dual ISO works better at lower bit-depths in lossless).

I use 12-bit just for experiment only, because I saw in ML note that 14-bit lossless recommended iso < 100 that's why I tried 12-bit uncompressed lol.
so, is it better to use just 14-bit lossless for all other recording too?

Correct, it seems you are using Full "Shutter range" in "Crop mode" submenu. This way you will need to read shutter speed from ML menu to get the correct shutter speed, and not from Canon overlay which would be incorrect.
ah.. I see, thanks bilal.. problem solved

hi bilal,
I got dual ISO flicker issue using 1440p 1x1 100/800 pressed record in 10x view
and one with standard raw 3x3 recorded in 5x view

here: Sample Files

btw, when using preset the shutter is changing now.. not 180° or 1/50?

What do you want to use on 700D?
Dual ISO waterfall lines fix is already implemented.

ow I didn't realize that..  :D
I thought this is something new

thank's bilal you are the best!
