Hello Levas,

I just try the last build magiclantern-Nightly.2020Jul08.6D116 and when I click SET button in the crop-rec menu on the advanced option nothing happen(but I don't really need it, it's just to report you the issue).
I also try sd overclock 240MHz and now my SanDisk extreme pro170/MBs card is able to handle the crop_rep preset continus (test only for 3min but it's enought for my use) 8).

Thanks  ;)

Cool, I like the pitch. The image is sharp too, do you use crop_rec or full sensor? Could you tell us more about your workflow?
#4
It's so cool, now we can choose resolution and framerate (by using safetymargin setting) :D.
Thanks a lot!

But the preview does not work (Half Press). The frame width is much larger than x5. it's great. sorry for my english
Preview works great, did you set in RawVideo menu : Preview<=Framing? Or aren't you talking about Liveview (view while recording)

1X3 is really sharp compare to 3x3, but  I can olny record few seconds (because of my SD) with 10bit 2:1 ratio (bitrate ~ 59MB/s):

Dual ISO is smooth too:

It also open with the right ratio in MLVApp 8)
Thanks again for the new functionality.

Updated Crop_rec again.

And I added a 3072x1728 x 16fps mode (maybe 16 fps can become 24 fps with optical flow)
Unfortunately I couldn't get it to work with canon 5x liveview, so you need ML preview for this preset.


Great I will check it today, I already love the 16fps :) . No other request for the moment :P

Not sure, but did you know, you can enter submenu of crop_rec with the 'Q' button when you highlight crop_mode in ML menu ?
You can change the bit depth in there, from 14 bit(Off setting) to 12, 10, 9 or 8 bit.
Should give you longer recording times.

8) Thanks, no I didn't think to go in this submenu, only try the mlv_raw bitrate setting but only 14 bit were available.
Thanks a lot for the new preset.

These are handheld footages but the lens I used has stabilization built-in.

Thx. Works great.

The 10 fps to 24 fps youtube link, not bad, but you can see the motion of the cat is a little unnatural. 10 fps to 24 fps is probably too much for most situations.

I agree with you 10fps is an extreme case.

Think I'm gonna add some more crop_rec presets this week to it.
It would be great! But 10Fps can still be useful in some situation as 5K 2.5FPS ;).
Thanks again. Take care.

The footage is great, it really feels cinematic. Could you teel us wich stabilizer did you use?

@Alexboum
I put the 3840x2160x10fps back in the crop_rec module.
You can download the module file from my google drive:
https://drive.google.com/open?id=1xlmsTMnIpLi5_Rr0JaW-pDi0nB9Mr03Q

Replace this module file with the module file in the lazy build on your SD card( ML/MODULES directory ) and it should work.
The 3840x2160 mode is for use in 5x zoom mode, if you use it in 1x zoom you probably get corrupted frames.

Curious to hear if you can get good results with Adobe optical flow or twixtor with this 3840x2160x10fps preset.
I only know Blackmagic Davinci Resolve optical flow, it's a bit of a hit or mis. On some footage it works great, on some it doesn't.

Thanks a lot Levas, preset works fine (No LV), my SFCard is too slow for 4K14Bit LL so I test it with 3K 16:9 10FPS (~45MB/s) (No aliasing). Camera is hand helded. It's not really natural but smooth enough.
OpticalFlow can be really good if the mouvement are slow and smooth, so stabiliser or tripod are needed to have good result. But I think it could be good for interview or Landscape footage.
On Youtube there is some good 50% slowmo at 24 fps so I assume it is possible to achieve good "normalmo" at 12fps.

PS: Resolution can be override on the preset.

All ok over here.
Only a little bit busy with homeschooling the kids besides my real job  :P

I'm still planning to put some more presets in crop preset, so I can put back in the 3840x2160 at 10 FPS.
Although it can take a while, will try and see if I can do it before the end of this month.

Thanks for your reply, no problem it's not hurry, I'am locked at home with the Covid-19 so it would only be to test and play with it.
So take your time and take care about your family it's much more important.

Found a few minutes to alter the crop_rec file to NTSC.
For the first 3 presets, camera must be set in NTSC 720p60fps mode.


Tested it really quick, so far it looks good  ;D

Here's the link to the crop_rec module file:

Hello Levas,
I would like to ask you if you would have time to add in the Lazy build the the 3840x2160 @10fps crop preset? It could still be smooth with mecanical stabilizer and good post production interpolation (twixtor or adobe optical flow).
And also to know if the Digital Dolly is active with crop_rec. I'am able to use it without crop_rec but not with. By reading the code it looks like the Digital Dolly is mainly handled by mlv_lite.c in the "update_cropping_offsets" function. So it look like to be active in your code but there is surely some subtlety.

Anyway, hope you are ok in this period and thanks for what you have already done.

Wait a moment! H.264 29:59 limit doesn't apply anymore? If true: What about other cams?

You're right but. You can stop the recording beetween two songs and restart the recording. With raw you have to change the CFCard and for 2Hours you need four 128GBCF, it starts to be expensive. But maybe it is possible to unlock the duration limitation with ML?

I've got it, thank you.

Is it possible to shoot an entire 2-hour concert with 2 or 3 5D Mk II? Using 128 GB CFs and power adaptors and ML 12 bit lossless RAW. Will the cameras overheat?

No you will got only 30min (12bit) 45min (10bit). You can use https://rawcalculator.netlify.com if you want to calculate record duration or bitrate ect.... But you can also use H264 with increased bitrate it's not as good as raw but it's better than default h264 and you could record for 2Hours!

#4b Is the current 10-bit and 12-bit video in 5d2 achieved without lossless compression? By truncated lower bits?

As I am want to do, I tried combining the old, hacky, but still functional 5d2 dual_iso module I had laying around with the exciting new 3K experiments on the 5d2.  However, I am met with a note on the module saying that it is an old API. "Expecting 7.0".

So it appears that a new attempt at dual_iso on the 5d2 might be timely. Hope someone is willing to give it a shot!

Hello jpegmasterjesse, I would like to know if you could make works the waza57 dual_iso module with one the raw_video_10bit_12bit_LVState  version? Because I got the same message about old API version. And my CFcard is to slow to write FULL HD 14bit but 12bit and 10bit iare OK  :-* .
If I recompile the module from source with the new API 7.0 will it work?
Thanks you for your help.

I just update/ported dual-iso video to 4k5d2 crop_rec branch , just testing right now --  5xZoom & 3x3 (FHD) work @ 10bit
check in MLV App , but I had to force dual iso process as it was not detected right away . I'll post a build shortly in
"3K/UHD 5D2 Raw development and Other Digic IV Cams" thread

Hello,

"if" CROP_PRESET_CENTER_Z = 1 the two last "if" will always be executed.

Quote

engio_vidmode_ok = (crop_preset == CROP_PRESET_3K || CROP_PRESET_CENTER_Z)
.........
if (crop_preset == CROP_PRESET_3K || CROP_PRESET_CENTER_Z)
........
if (crop_preset != CROP_PRESET_3K || CROP_PRESET_CENTER_Z)



Is it what you are looking for? If not you can maybe try:
Quote
engio_vidmode_ok = (crop_preset == CROP_PRESET_3K || CROP_PRESET_CENTER_Z)
.........
if (crop_preset == CROP_PRESET_3K || CROP_PRESET_CENTER_Z)
........
else if (crop_preset != CROP_PRESET_3K || CROP_PRESET_CENTER_Z)
........

With this synthax only one "if" can be executed. (If the first "if" is true the "else if" is ignored).

Hope it can help you.
Anyway thanks for your amazing work.
