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.
watch in 4k!

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!)

no effects of any kind were used.  it's just from the lens.
the only post processing i did at all was adding the golden colour to the flares.  somehow, white just didn't work for me!
it's hard to believe it's been 2 years since i shot that video.  i should shoot something new with only candlelight to see how much better it looks today with the progress we have made with gain optimisation...

here is the test clip.
this was shot at iso 800 without dual iso.  the exposure was set for the very bright led bulbs beside the big monitor, with no clipping.  the room is quite dark, with a 15W led bulb behind the large monitor for indirect light.
no noise reduction, but i (always) desaturate the blacks.  any colour there is just chroma noise!
there's no key light in this test. i lifted the shadows by 1.5 stops.
this is a test of the "halation" plugin in resolve.  that's what is making the bright objects glow...

thank you!
i use the uhd 1:1 preset and then just set the resolution to 3840*1536 in the submenu.

card spanning and overclock is required.  i have a sandisk 170mb/s card that i overclock to 160mhz.

it's important to disable global draw, and your first recording of the session will only go for a few seconds and then stop.  after that, long recordings are possible.  if you don't clip too much, continuous is possible until you run out of space!

hey everyone, it's nice to see active discussion again...

i've found that youtube quality goes up if you upload at least 2560 horizontal resolution with a suitably high bitrate such as 20mbps.

i'm preparing for my next music video and it seems like the test shot i made last night with no key light is worth sharing here with you all...  i'll upload it and share a link here.

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!

Reverse Engineering / Re: UHS-I / SD cards investigation
« on: December 22, 2021, 05:22:17 PM »
Hi all,
I'm feeling the itch to buy an SD card for my good old 5d3 if there's anything that might be worth testing for overclocking...
The sandisk 170MB/s extreme pro I am using now is excellent and always reliable, so I don't "need" a new card, but if there's something new with the right udma characteristics that may be faster, I'd order one to try it out!
Has anyone been keeping abreast of anything new and interesting?

thanks for the compliment!
timbytheriver helped make it possible, and we continue to improve our joint effort.
i tried those other options you suggested long ago and both create more problems than they solve in my experience...

i remastered the video after making a different processing technique, pushing it even harder and it didn't break!  it really shows in the studio scenes where my face is visible.

updated top post link.

thanks to you both!
i'm slowing down with using the camera lately so it's not a huge loss to me if i fry it, but we'll see ;)
i've been thinking it over, and i am not sure if calibration would actually fix the last issue that i'm facing: the ugly vertical "scratches" in the darkest shadows when pushed very high in post.  it might help a bit, but i am not sure if it would make a real useful improvement.
i'm thinking about an approach to fix this...

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.

5d3 14 bit

the intro added, and a playlist for the full experience:

really well done!
the visuals were great.
the only issue i spotted was some shadow halos in the shot where the woman was backlit and you lifted the shadows.  hopefully mlvapp will improve in that regard.  since you use resolve, you could have processed that shot in resolve to lift the shadows with no halos.
other than that small issue, flawless!

with regard to the editing, two small items that caught my attention (distracted me, actually)

the shot of them outside in the grape vine area showed a bunch of grapes at the end of the shot in the upper left corner of the frame.  i was waiting for a focus pull to the grapes!

the first camera walking shot of the father and son began too early in the source footage.  there was a second or so before he began to walk and it feels awkward.  better maybe to cut straight to the scene in motion?

small points.  nice work!

the resolve image looks darker because of the hdr workflow.  ignore that, it's the same frame.

i'm just sharing useful information.
