I already bought your lut and I also planned to buy pocket 4K and I was thinking about the possibility of having an Alexa Conversion lut designed for it.

Great news!

That's what I'm thinking - granted I don't get hit by a bus or something

I always liked Black Magic

Big fan of this LUT! I've been playing around with it for a little bit now. Here's some stills using it. This was graded in Premiere and the border was made by myself using different sources.

Those are really cool. What's your approach there? How did you set WB? I want to get a magenta/color light to experiment with in my next night shoot

I am SO glad I've moved to Resolve. It deserves it's rise in popularity.

@Sage  as you mentioned the Pocket 4k, any chance you are planning on creating  a Pocket 4k Raw and Pro Res to Alexa Conversion work flow?

Thanks!

Mark

Yes! That's what I'm thinking

@Sage I can imagine you get requests every day to make Alexa color for the iPhone or for Sony or for the PixelVision 2000... lol.

There are a lot of ifs in my scenario, but if I go with a Panny, I’d imagine even with 8bit, your CineLikeD process could work? The magic is in the skintones so maybe even some experimenting with zebra strength could do the trick. If I go that route, I’ll keep you updated. Thanks. 

Ah yes, the PV2K!

CineD is just the ticket for the 8bit Panasonics. Moreso than VLog

@mercer Right now, I'm re-evaluating the entirety of the process for efficiency (Model 3)

The GH5 with EC is all I've ever wanted; it would be nice to be able to support other cameras per request, as there have been many (and still manage film making!)

@mercer Thanks Mercer; consider the GH5 - the big deal, for EC, is that it has 10 bit 4:2:2, and it can be had for a couple hundred more than the G9:

Another factor is that the Pocket 4K is coming out soon, and it will only be $1300, with a full Resolve included. What do you think of the Pocket 4K?

If I got a hold of a G85, I could support it, probably via Cine-D. Likewise the D5500; the key with 8bit cameras is finding the right balance between captured DR and gamut bounds, and data density

An interesting qualifier for us is "video"

Steven De Sarno sent these stills from high frame rate 8bit this week:

You are stuck in today's video vs. photo paradigm. The technology already exists for dual ISO so why not dual shutter speed? or a still image taken at 1/250 or 1/500 or whatever taken in between each video frame or every 10th video frame & stored separately? There are so many different ways this could be accomplished. The 8 Megapixel stills that you can grab off a 4K timeline are sensational & can be used for any commercial purpose from wedding albums to magazine covers to billboards. 

That's a great idea.

At the moment, there's Reel Smart Motion Blur (computer intensive though)

Stills with 180d blur are cinematic, as long as you can get one resolved enough..

@Sage beautiful work! Due to the slight difference in color science, how you think this would work with the GH5s?

From what I've seen, it seems to work well. For example, the difference from Alexa color science is astronomical by comparison

This is an S frame from Jeff Cowie that I prepared with EC and black level placement earlier this week:

Ah, I was thinking V-log did the corrections once taken out of Cine-D or Standard mode, I'll double check mine then.

 

But 50% is skin tones still eh?

That's where I set Zebra 2, but there is a degree of flexibility to it. As long as skintone is between 40-65, you'll get a rich exposure in that zone

Regarding Luma placement (tying in to exposure), I wrote in an email earlier today:

"Yes, the nature of the conversion is professionally oriented, to treat all usable DR equally (hence the lower contrast). An artificial black level limit is not placed on the footage to give an impression of immediate added 'pop', and is rather left to the colorist. Luma placement is the simplest operation, whereas the intricate color interactions are taken care of.

I may add an 'Auto' variation in the future in addition to Main/Soft/Pop, so that not even Luma placement is required (!) (at the cost of flexibility)."

EC/V35 Flipbook (Gradient banding from .gif):

For VLog exposure, you'll want zebras at 80% (clipping), and I have the other at 50%.  Above 65% is the rolloff, meant for over-bright highlights

I'll be taking a look at the .vlt situation at home, perhaps there is a setting or something else at work here

10 minutes ago, Maverick530 said:

I was reading the pdf for the cine D and saw the luminance should be set to 64-960 (Or something like that) but what am I suppose to set it for 8-Bit during VFR modes?

And also, I added the .vlt for V-Log assist, but it only looks like it adds a little saturation to the picture, is it suppose to add contrast too?

Hey Maverick530! Cine-D should be set to the equivalent for 8 bit (I can't remember the exact numbers off the top of my head, stranded at work atm)

The .vlt adds saturation and contrast for VLog monitoring (the contrast extending the black level down to 1 IRE, the highlight ceiling the same)

@Sage you have a conversion that works with CineLikeD, right? If so, has it ever been tested with a G85?

I do, you can get it for free here

I don't know how different the G85 CineD is, but granted the overall similarity of VLogs, I would imagine it to be close

Awesome, seems to respond really well! 

I'm using Verde on a new food commercial - will share when it's done! 

Yes Please! I'm looking forward to that. Do you use Resolve?

The area where EVA could have a nice boost is the handling of the top end of DR. Current EC has an ideal rolloff for the GH5, whereas the EVA could have a roomier EC

7 hours ago, Oliver Daniel said:

 

and certainly the GH5 is another camera with @Sage insane Alexa conversion. That thing is nuts!

Thanks man, I appreciate that (greatly).

@Oliver Daniel For an idea of how current EC works with the EVA, here are a couple of tests images (from Slashcam and Best Film & Video):

With Emotive Color

EVA1 - Vlog

EVA1 - Emotive Color

AMIRA - LogC

(Granted the cameras, unsupported light sources, WB etc, I'm pleased!)

Thank you! Wow, Davids and your VLOG footage look so good without grading...   I think something wrong with my exposure... 

I wish to know how he set exposure and wb for this shot.

I asked him. For me, nothing fancy. I shot the entirety of the outdoor shots in Always Already with the sunny preset, no post correction or color grade. For exposure, I generally aimed for a little brighter than I have in the past, just by eye, but not ettr (i.e. not placing just at clipping). Its ideal not to place significant image areas in the rolloff (65-75), or to significantly underexpose. The vlt preview gives a good idea of the resulting image (eye viewfinder gives accurate contrast)

*His response:

I always custom white balance using my x-rite colorchecker.

I exposed it so it was not clipping (except the sun).

The new luma placements of EC is quite right to judge exposure by eyeballing the V-Log Assist 1D LUT.

Othwewise, i would have ETTR it and used my luminosty mode layer to drop down exposure while keeping the noise level to a minimum.

*I think he might be referring to another sun shot he sent me, but it covers the bases

Here it is:

@tihon84 Here's what David said:

"No grade at all, it’s plain GHa Daylight (Main).

Maybe just a slight luma correction, but i’m not even sure on that one.

I’ll send it to you soon, i don’t have access to my computer right now."

He's going to share the VLog

12 minutes ago, tihon84 said:

nice!

I think it`s not only LUT applied? DO you know what was a postprocessing?

David usually just places luma as in the PDF. I'll ask him, and also for the Vlog version

Did you get those last two Vlog shots?

From David L'Abbée:

OLPF 20%, 7 Blur, with the Sigma 18-35mm

Yes, v2.2 is an update for the central GHa conversions. I am thinking to redo the supporting PREs soon, but that would've delayed 2.2 for awhile. I wanted to get v2.2 out as soon as possible, as it is a "paradigm shift" (finally in that 'perfection' zone)

Just a question @Sage

What happened to the CineD conversions? They seem to be gone?
Thought they were quite handy since I prefer the 4K output over the even stronger sharpened 1080p output for 60p.

Do you mean for v2.2?

@Coiii @Wild Ranger I would like to.. supporting the GH5 fully has been time consuming. If I do support more, I would like to make sure its quality work, and fully supported. If I could do this full time, that would be awesome. I've got these other offshoot(s), that is/are potentially amazing

@Wild Ranger That looks incredible! Totally love the grade there
