Thank you very much for the test...
If somebody can compile the build that A1ex suggest, I will test it.

Does anyone have tried Dual ISO in crop_mode? It seems there are problems there. Frames (after Dual ISO Processor) comes with stripes like unprocessed dual ISO frames. At least with x5 (x3) zoom. Is there some solution?

Could you post a sample file?

Actually it comes with stripes with, and with no zoom. Here it is:

Ok, trying to understand what to look for.
The non crop file seems ok. After running the file through cr2hdr I get this.

Checking your file frame_000008frame_000024_crop_mode_with_zoom.dng it doesn´t look healthy. So you´re problems are only the crop mode recording with compressed 4k modes? If yes, could you share a small MLV sample instead of a single dng file?

Try to zoom it. Non crop I mean. And how did you running it through cr2hdr? I tried but it just flashing and nothing.

Thid mlv file with no zoom. https://yadi.sk/d/7nw0j1Fq3HmYpN (with zoom pretty big for half Gb mininum). As I see, problem with stripes is in unzoomed DNG's (RAW Dual ISO on crop_mode build just fine as well as Dual ISO MLV's on older builds).

The mlv file you just posted @savely converts just fine.


I´m on mac and using this. It´s a1ex cr2hdr binary working.

*update 3
Pull request made here
https://bitbucket.org/Dannephoto/magic-lantern/commits/642fb8c4d5bd7bd8169bc9b85bae11eb27495892


I´m already a big fan of the crop_rec4k mlv_dump version and the compression of dng and MLV files are great. Encountered an issue with eosm footage. Files won´t parse(open) in acr and dcraw reveals what´s wrong. Corrupted file. Other footage from eosm is working.

Testfile:
https://bitbucket.org/Dannephoto/magic-lantern/downloads/M20-1113_samples_Issue_parsing.zip

dcraw output and terminal message:
 
Code: [Select]
Unexpected end of file

*update.
Maybe metadata related. Other random ml builds is working with eosm. Guess I was lucky with this corrupted footage  8). Wish I knew what build I was using when filming. Have a bunch of files om my computer which comes out like this. The transcode just fine with other builds of mlv_dump.

*update 2
It seems it´s because of being 10 or 12 bit footage. Guess that´s not working at the moment with the crop_rec4k mlv_dump build.

Can you please upload your "fine" result? Cause in crop mode build with Dual ISO I always end up with striped pics or this pattern:

I just shot a 3x crop of a hummingbird on a perch with a 70-200mm lens. This is just insane detail. 3072x1228 12bit lossless.

Download the movie and watch it in ProRes. Literally moving photographs.

wow. Can I ask a favor? Would you mind sharing a single dng frame of that hummingbird that I can look at in davinci? That's beautiful.

Thank you, the image can still be zoomed to fill an UHD timeline in resolve. Nice.

I'm certain I can get 3520x1320. Not sure that offers a 3x crop option though, I just didn't dive into the settings that hard since i was trying to capture the little guy before he took off.

3520x1320 works for me but only up to maybe 100 frames (KomputerBay 128gb 1066X CF card). But I have only tried it in the 14-bit lossless mode, 24fps. Is anyone getting longer recordings using 12-bit lossless instead?

Great looking footage, by the way!

I was getting continuous in 12bit...

all this...most of these scenes were in the 20-30 second range before I cut them shorter. I was using KomputerBay 64gig 1000X

I realized after posting yesterday that 12-bit lossless and 10-bit lossless aren't enabled yet for the 3K/4K crop modes anyway. So 3520x1320 was continuous for you in 12-bit uncompressed? I'll have to try that out! I just assumed the larger bitrate would be prohibitive, but maybe it's something else that inhibits the 14-bit lossless from doing it continuously at that res?

I'm not sure these are accurate rec times mentioned above. Possibly I guess but as far as my testing has shown, 3072 2.35:1 23.976fps override on the 5x mode in the crop rec menu @12bit lossless are continuous. Even with these settings there could be scenes that can spike the data rate so that it is not continuous. Above that resolution, I don't THINK you will see continuous. Remember, if you are using the 5x option under crop rec menu, you have to hit the zoom button to actually rec the resolution. If you don't it will just rec 1920. I'm thinking maybe that's where some confusion can happen. If your not zoomed in the 5x option in the crop mod you will not be recording higher then 1920 resolution. Also if you are using the 5x mode you will need to enable fps override since canon live view defaults to 30fps when zoomed in.

I shot 3520x1320 12bit continuous in the 5x centered mode continuous for 2 minutes last night. It made a 10gig (ish) mlv file but it did it. It's definitely doable.

Oh I didn't realize you were using 2.66:1 ratio @giarcpnw
And you mean 12bit lossless right?
Also did you hit the zoom button before recording?

If you are in 12bit  lossless mode Try to ETTR really branchy tree tops with no highlight clipping on an over cast day and I bet your data rate will skyrocket with those settings. It did for me anyway.

Yeah sorry. lossless. Always lossless. Can't seem to get past 3072 if 14bit lossless. I've not seen a big diff between 14 and 12 bit to try to go higher.

Recording @ 3.5K 12bit Lossless is really tricky it all depends on your scene.  3072 - 12bit Lossless is working lovely.. Live View stay's full color and I'm able to focus properly.  Not sure if anybody experienced spiked data rates using the Sigma 35mm ART lens, or any of the ART lens.  I'm thinking that because those lens are soo sharp it's causing that issue.

@goldenchild9to5

Do you get real time liveview with 3072 - 12 bit lossless?. Full color but no realtime, isn't it?

Thanks.

@pc_bel, @goldenchild9to5:

Have a look at the preview options; the help text has some hints for your use cases (also discussed earlier in this thread).
