Tragic Lantern / Re: Raw video on 50d and 40d

« on: July 16, 2013, 07:39:04 PM »

It's nice weather here in the UK at the moment so I went and shot another raw test.

- Used Tragic Lantern by 1% (11th July build compiled by Andy600)
- Mostly shot at 1584x892 and upscaled to 1080
- 1 or 2 shots in 5x crop mode

- DNG's extracted with RAWMagic 1.0 Beta 7

- Raw processing in ACR
- Tamron 17-50mm f2.8

I'm getting more accustomed to the workflow now. I did a light 'logish' grade in ACR rendered out to Prores 444. Then applied a custom LUT in Resolve, tweaked it and added a little sharpening.

Yeah there's no solution that's perfect at the moment. Maybe Resolve 10 will offer debayer improvements.

@Andy600

Here's your jpg processed through ACR. It's removed most of the smaller moire artifacts but the woman's shirt is too far gone. Also I suspect there will still be a fair amount of aliasing/flickering left over in the motion version.

Did you process in Resolve?

@RockFallFilms - Can you try this build and let me know if you're still getting that left border. try normal and crop, largest resolutions you can select.

The test again with width set to 1920 x (any height)

https://bitbucket.org/andy600/andy50d/downloads/Andy600.50D.ML.Border.Fix.Test.Build.Not.Official.zip

Delete your raw config file first.

Yeah that's fixed it, no black borders now at the following resolutions:

1584x892
1984*1080
1920*818

I did get all pink frames when shooting at 1344x756 though.

@rockfallfilms you should be seeing more but I think Grayscale Preview is broken or maybe bypassed atm. I have the same issue now.

Ah right, at least it's not just me then. Do you get the black line on the left of frame too?

Regarding 5x crop can someone tell if what I'm doing is correct?

I activate the following in the menus:






This is the view i get in 5x crop mode




This is what it's like whilst recording:



and this is what the dng looks like.




Is this correct or should i be seeing more of the frame on liveview? As it stands composing a shot is difficult as the LV image differs greatly from the recorded one.

Cheers

Have you tried deleting your config files? Delete everything off the card and copy Gregory's build. I just checked and I'm having issues with raw preview modes too

Yeah I've done a clean install from a format. When in normal mode, pressing the middle joystick is snapping the focus box to the middle of the screen so the joystick appears to be working ok. In 5x mode, pressing the joystick just moves the focus box around the screen randomly on each press but doesn't change the preview grey or let me see anymore of what I'm shooting.

When I long press it goes to a menu, I thought the camera was faulty but it looks like it's supposed to do that.

What build are you using?

Todays unified that @gregory posted at the bottom of the other thread.

Just tried your June 18th build and get the same issue.

I'm still having an issue with previewing in 5x zoom mode, only getting the centre part visible so framing is hard.

I've activated the settings people have mentioned and I'm beginning to think I might have a faulty camera/button but just wanted to check again.

My settings are:

Prefs, snap points - "center to 5x raw"
Movie, Raw video, preview, "ML Grayscale"

When i press the joystick in 5x mode it just takes me back into the ML menu.

Any ideas?

Have you set snap to center 5x in zoom box settings? Then press joystick in zoom mode to center on the crop area.

Yeah I've got that selected aswell. I get the greyscale preview when recording but the view stays the same with or without it. I still only get to see the middle of the crop.

I'll format the card later and try a fresh install, maybe something has got screwed up.

Thanks

Grayscale preview shows the recordable frame size so you don't have to guess. Set it in the raw module

Yeah I've got that switched on but the liveview image still differs from recorded one. Maybe I need a different build, I'm using 19th unified.

@Andy600 It looks nice, very filmic. I tried crop mode but didn't find it very practical to use as I could only see the middle part of the frame.

« on: June 20, 2013, 10:56:05 PM »

I have a Mac Pro early 2008 8 core 3.0ghz. I put a GTX 560Ti 448 in it and I get 18-25fps in Resolve. AE renders pretty quickly too. Resolve gives me a GPU not supported warning but still works fine. You could also put a GTX 570 in it.

I think maybe some kind of petition will push Mosaic Engineering to develop AA filter for 50D?

I emailed them 2 weeks ago and haven't heard a thing. Perhaps if everyone does it then we may get a response.

Good to know I'm not the only one...
It's blue on one side, orange-ish on the other side. Barely visible with BMD Lut, but really annoying in the final result.
I'm using  raw2cdng.1.1.6. That's the only option I think.. (Windows).

I've just done another test, I'm not getting the issue when using RAWMagic on the Mac. It was only happening when using Raw2dng.

I'm getting weird results in Resolve.
Colored lines around the frame and a 1px black border.

The CDNG file is fine (converted with raw2cdng.1.1.6) if I open it in Photoshop so must be a setting in Resolve somewhere I suppose.

Anyone seen this before? What could it be?

Yeah I've seen the same thing, it is a blueish colour on mine. I think it must be how Resolve is interpreting the DNG's. What do you use to extract DNG's from the ML RAW files?

1. DNG to Lightroom (specifically to save latitude)
2. export upscale to 1920px horizontally at 100% JPEG quality
3. edit in Premiere CS6 (JPG frame sequence)
4. export as DPX LOG frame
5. color in AE CS6 (combination of adding a specific LUT base, then grading in curves, sharpening and adding 35mm grain scan)

As Andy600 said, you are exporting as jpeg and killing your colour information (going from 14bit to 8 bit) then grading an 8 bit image in AE.

A better workflow would be to open the DNG image sequence directly into AE via ACR, that way you keep all your colour info. Then you can export out of AE as prores 4444 or DNXHD and keep it at least 12bit.

BTW the best sharpening and upscaling method I have found is to work in Davinci Resolve Lite (FREE). I can't get Premier Pro or After Effects anywhere near the same quality without artifacts. See this: http://www.magiclantern.fm/forum/index.php?topic=5586.msg50829#msg50829

I second that, Resolve's sharpening algorithm is pretty good. The best results can be had by sharpening only the luma channel and not the chroma, this will avoid colour fringes.

Or use the CDNG and DaVinci workflow. Much cleaner.

Unfortunately Davinci's debayer isn't as good as ACR and I find the DNG raw controls pretty limiting. Also ACR's chroma noise reduction does a good job of reducing moire.

There's no perfect workflow for me yet, I'm hoping resolve 10 will improve things.

It happens with all the processes to varying degrees, 2010 is slightly better but doesn't cure it.

You can turn off autotone so ACR stops guessing but this is the way I understand it:

if there's a change in exposure during the scene like the sun coming out then the frames with the brighter sun would inherit the same changes which were made on the 1st image that was changed in ACR. (with darker initial exposure) I believe that the only real way round it is to find the brighter frames and make different corrections to them to compensate. That would take too long though!

What is needed is some kind of smooth transition between frames to iron out any differences in exposure. Out of all my shots so far, I've only had an issue with one so I'll just live with it for now!

and a lot more "flickering" as in jumping aperture. 

This was probably caused by Adobe camera raw, I got the same issue as have others. ACR seems to be doing auto adjusting behind the scenes and causing a flicker in the highlights. So far there doesn't seem to be a solution, other than going direct to Resolve.

I've just bought a couple of Duracell DRC511 batteries, replacements for the BP-511A. So far they are lasting pretty well and they are only £14 each.

Greetings  !
I've been testing raw video on my 50D for about a week now..

The first problem I had was, that my computer froze with .raw file on my card (via card reader). No idea why, but compliments to the 9th June update, which solved that problem.

My current problem is, that I can only record 12-15mb/s on raw recording. I have 16gb sandisk 30mb/s card (it achieved 27mb/s write rating on ml benchmark test). I have the latest update installed (from 11.6.) and i have formatted the card in camera (keeping ml).
Before the last update, it was even slower, about 10-12mb/s.

I scrolled trough the last two pages and noticed that you guys have much faster speeds.. Am I doing something wrong, or why does my card perform only 50% of it's potential?
Thx
(i hope I haven't opened up a solved issue..)

Your card is too slow, most people are using Komputerbay 64gb 1000x cards which are rated at around 100mb/s write, although most people are getting about 70mb/s.

Your 16gb sandisk 30mb/s card won't write fast enough so the buffer will fill up and recording will stop.

How is everyone working out the framing in crop mode? I just had a play about with it but it's hard to know what's in frame.

Rockfallfilms: Try 1920x960 in 5x zoomed mode. It needs 73.7MB/s. Or 2000x910 at 72.8MB/s.

All of a sudden I'm only getting 40mb/s in any mode i try. Card must need a format.

Ok, it's picked back up again but only to 65mb/s in the resolutions above, recording stops pretty quickly.
