Share Your Videos / 5d3 candlelight video remastered in dolby vision
« on: April 22, 2022, 06:12:51 PM »
I thought this was already as good as it could get, but again, dolby vision gives just a little bit extra!

it was a little more difficult to handle the flames, as there were some vertical lines in them, but it was easy to fix in resolve by using a node that was keyed to them and applying blur on the red channel only.

after having graded a bunch of videos with dolby vision, i've created a power grade for resolve that incorporates everything i've been doing manually, which actually isn't that much...  mainly sat vs sat and lum vs sat curves and a few other adjustments on the wheels.

i applied that power grade to this video, and did nothing else:

I've been re-grading more videos with Dolby Vision, and the results are fantastic.
This video was shot in low light, and the richness of the colour palette is phenomenal, with no banding to be found, and grading with Dolby is so easy!
Basically it only requires careful adjustment (rolloff) of the lum vs sat and sat vs sat curves on the right side of the curve. I'm guessing it is an issue somewhere with how resolve reads MLV DNG files?
It's not too difficult to adjust.

effortless grading with tim's dolby vision trick!
all i did was roll off the saturation on the highs and pull back the highlights to exactly 1000 nits on the HDR scopes...
the closeup at the end is breathtaking.

timbytheriver came up with a method for hybrid HDR-REC709 processing with Dolby Vision, and it made a dramatic improvement to this example video I shot a few years ago on my 5d3 (3072*1308 14 bit)

I previously had serious difficulties with the more extreme dynamic range shots, particularly the closeup of the oscilloscope.  It formerly required trickery such as spot exposure reduction on the LED to get the right saturation without losing all the contrast in the rest of the shot.  Now it was straightforward and looks great with no trickery!

This workflow also revealed details that were previously absent, such as the sky through the (filthy) windows in dimly lit interior scenes.  Incredible colour!

On another note, I was so pleased with the new grade that I re-rendered the blender animations, and in the process I found that the "eevee" realtime raytracer is now very close to production ready, so I used it, and it was a real game changer.  What a treat to see lighting adjustments on the fly...

timbytheriver suggested I should try using mlvapp to do basic exposure and colour temperature adjustments and then use the arri preset to export for editing and final grading in resolve in arri log c (using the CST plugin).

I gave it a shot for this music video and I'm hooked!  The fantastic mlvapp colours make it into resolve!

Shot in 14 bit raw on my trusty old 5d3 @ 3616*1536 using card spanning and overclock. (except the cellphone footage of the guitars!)

Share Your Videos / TOO DARK for dual ISO!
« on: December 24, 2021, 04:35:33 PM »
The opening scene of this video is by far the darkest scene I have yet pulled off, far darker than the candlelit scene (which had nothing but 6 candles).
ISO 1250, shot at 3616*1536, 14 bit lossless with card spanning and overclock.  NO noise reduction, exposed for the fiber optic light curio.

The rest of the video is dual ISO with much more light.

Watch in 4k in a very dark room!

This seems to be the limit of what can be done with the 5d3.
I'd like to try the sensor calibration that has been stalled for years, and I'm willing to risk frying my sensor!

I've gotta say, ACES 0.1.1 in resolve 17 is pretty amazing for magic lantern raw footage!

watch in at least 1440p for no quality loss.

The new debayering algorithm in resolve 17 works wonders with 5D3 3x3 footage!
It's so great that I no longer use other modes.
Real time correct preview is another treat!
Everyone with a 5D3 needs to try this.  I hope someday mlvapp will be able to debayer this well!
Seriously, this is a whole new lease on life for the 5D3.  I wonder if the 5D4 has a similar 3x3 mode?  Imagine what it could do with that improved sensor...

I wasn't 100% convinced that DWG was beneficial for SDR video, so I shot this extremely challenging scene and it really makes a difference!
When the clouds roll in, it stays beautiful.  This is static processing: one setting for the entire scene!

« on: January 17, 2021, 06:45:10 PM »
With the talk about youtube performance, I thought I would give it a serious test using TNT at 1440p:

I shot this at 2560*1440 (14 bit using TNT) and graded it in resolve to put all it's got into the darks.

Watch it in a dark room on a good screen at 1440p!  Look closely at all the textures and detail of my black shirt under the coat.

As always, no noise reduction of any kind.  TNT at its best!

Encoded using NVENC h.264 @ 30MBPS

if it wasn't for the subtle vertical stripes noise in the bright midtones (such as piano keys) I would call this perfect looking...

windows resolve users can now work with card spanning straight from the cards!

i combined the "lossless" version of mlvfs.exe with a newer version of dokan, and packaged it with my little batch file for "linking" 2 cards into one virtual drive, and added a readme file to provide step-by-step instructions.

once you are set up, you can take your 2 cards out of your 5d3, put them into your card reader, and resolve is ready to rock!

when i was grading/editing this video in resolve, i ran into a nasty bug...

my 5d3 has a stuck pixel, almost dead centre of the sensor (of course!) and i always take care of it with the "dead pixel fixer" plugin in resolve.  the plugin stopped working when i loaded this footage, and i went looking online for any hints as to what was wrong.  luckily, the search was good, and i found it happens when there is resizing at the "clip" level, which is what i was doing.

so i disabled the resizing, and changed the project settings to the exact desired output resolution (in this case 3840x1584), with "mismatched resolution files" resizing set to "stretch to all corners":

i set the timeline to match.

when rendering, set the resolution to 3840x2160 and ignore the warning.  it will then add the black bars to the render.

the plugin worked again, and as a bonus, playback was much smoother - realtime, in fact!

hope it helps someone...

Raw Video Postprocessing / windows bat file for card spanning with mlvapp
« on: October 03, 2020, 01:06:04 AM »
this was originally posted in the mlvapp thread, but i just noticed a new user who didn't know about this, so it seems like a good idea for it to have a separate thread for easy discovery:

i wrote a very simple batch file for other windows users to use:  (input it as a text file and then save as filename.BAT)
right click on the icon and choose "run as administrator"

Code: [Select]

@echo on

SET SrcRoot1=L:\DCIM\100EOS5D
SET SrcRoot2=S:\DCIM\100EOS5D

FOR %%A IN ("%SrcRoot1%\*") DO (MKLINK "%TargetRoot%\%%~NXA" "%%~A")

FOR %%A IN ("%SrcRoot2%\*") DO (MKLINK "%TargetRoot%\%%~NXA" "%%~A")


it's obviously set for my paths, so adjust to your specific settings.  make sure to create the destination directory before running the batch!

i'm using a ramdisk as drive A, which is a convenient place to stick random junk like a pile of shortcuts for a single use :)

NOTE: the destination directory must be formatted with NTFS

Share Your Videos / new music project from TNT
« on: September 28, 2020, 07:01:36 PM »
shot on both sides of the atlantic, using TNT of course ;)

it only made sense to call our music project TNT also! :)

magic lantern brought us together to hack our cameras and make music too!

the song was inspired by the sudden catastrophic loss of all the butterflies in my forest after the farmer next door poisoned his fallow field in late summer.  i'm playing my keyboard on the boundary between my forest and his field.

i sometimes use 18fps when i want a different cadence, and i find it suits this kind of video.

maxed out resolution @ 2:1 AR, recording strictly to CF, 14 bit:

there's definitely extra efficiency in danne's 3.x k modes.

there's definitely something magical happening with danne's new 3.5k 5x zoom mode.

i was feeling lazy so i shot this episode on my CF card only, at approximately 2500*1250 (2:1 AR) @ 23.976, 14 bit

and it was as solid as a rock.  no stops with several 10-15 minute takes!

the new realtime preview is a joy to work with.

there's some serious magic in magic lantern these days...
