Parker Posted January 28, 2020 Share Posted January 28, 2020 @mercer The thing I always notice about GHAlex compared to other luts is how it just adds a nice sort of clear separation to the skin tones, in both color and b&w. It just adds a midtone pop that I really like. Sage and mercer 2 Quote Link to comment Share on other sites More sharing options...
Sage Posted January 29, 2020 Author Share Posted January 29, 2020 The 1080p mode on the GH5 is really quite good; if like me, you are happy with a dense 2K image, then 1080p offers the most bitrate saturated options in the camera (no affect on color) Cine-D has a slight bit depth density edge over VLog, while VLog has a slight extreme gamut edge. With 8 bit, Cine-D is decidedly better Great work Parker and Benjamin! Alas, I've got to get the next update out.. Just finished writing one last tool that I believe will be critical for automating camera support, to do the Exp Pres (it is the fourth 'sub-section' of the ECE) mercer and Parker 2 Quote Link to comment Share on other sites More sharing options...

I assume you have specific, recommended settings for CineLikeD? I'm mostly curious how the highlight detail is with CineLikeD compared to vLogL after it's run through your process? If I can find a GH5 at the right price, 1080p will be my mode of choice so it's good to hear that the quality is so good... especially since you can use the cheaper SD cards.

Sage Posted January 29, 2020 Author Share Posted January 29, 2020 With Cine-D, you'll want to set Saturation to -5, and the rest at default. Also, use ISO 200 (instead of 400; 200 is the electronic equivalent of HLG/VLog's 400). Highlight range (and gamut) are a 1:1 with HLG/VLog, once PRE'd.

I assume you mean as a base ISO and not an only ISO? Obviously, like with most cameras, it's best to stay as close to base ISO as possible.

Here is an overlay of samples clipping (VLog overlayed on Cine-D): And finally do you recommend a similar exposure process with CineLikeD as you do with vLogL? I haven't read your manual but I assume it's either an ETTR or a waveform exposure putting skin tones around 60 IRE... or whatever! Quote Link to comment Share on other sites More sharing options...
Sage Posted January 29, 2020 Author Share Posted January 29, 2020 Sharpness at -5 for sure. NR can be a personal preference (some are noise averse and prefer the ease of NR in cam). Though -5 would be the Arri equivalent, from a purist perspective. Indeed, for VLog, 400 is the base. Then it goes to 200 for Cine-D, but this is just the labeling (200 really is 400, in VLog land) Yes; lately I've been recommending the simple rule of thumb to anchor everything around the center of the waveform (leaning higher rather than lower), no matter the profile. This is because all profiles share this middle 'cross point', and diverge from there (with varying contrasts), and 50-60 is generally where midtones should place (in exposure for EC709, not for post placement). The great news is that exposure/luma is about to become a breeze, in roughly a week. majoraxis and Video Hummus 2 Quote Link to comment Share on other sites More sharing options...
Video Hummus Posted January 29, 2020 Share Posted January 29, 2020 Vlog does have the custom view assist .VLTs...otherwise, I don't see many drawbacks to shooting CineD. Sage 1 Quote Link to comment Share on other sites More sharing options...

JISU Posted January 29, 2020 Share Posted January 29, 2020 I bought ghalex in 2018. I have not received any update mail since V3. Is there a V4 version? I only received 33X at the time, how can I get the 65X version? Quote Link to comment Share on other sites More sharing options...
Sage Posted January 29, 2020 Author Share Posted January 29, 2020 They are Exposure Pres, conversions made with the same interpolation system as the other conversions (converting color in the mix). Its a lot of fun to use in conjunction with the conversion. The P4Ka workflow video shows it in action in Resolve, though it applies to every NLE (and the Posts, which are an essential part of the picture): They may be stacked in order of greatest to least, and all may be used in conjunction with gain key/opacity to dial in an exact value (Post or Pre). majoraxis, mirekti and seku 3 Quote Link to comment Share on other sites More sharing options...

So, yes that is a great compliment and makes the GH5 a little bit more appealing to me... maybe @Sage can create a GHred workflow in the future. In my opinion, this seems more appealing than making an Alex version for every camera on the market. Can you share the video you showed the director from the TV station?

saame Posted March 3, 2020 Share Posted March 3, 2020 @Sage On the V4 documentation in your website, under Post-workflow, it says that "1. If you recorded to Cine-D (Sat -5), HLG, or VLog to ProRes/DnxHD on an external recorder, apply the appropriate [PRE] file to the first node to convert to normative VLog in advance of the color conversion." Currently I'm shooting 10bit 4:2:2 HD 200Mbps ALL-I in camera, but converting it to 10bit 422 DNxHD (with the great "V6" tool by Wayne Norton) before bringing them into Resolve, as Resolve doesn't recognize the straight-out-of-camera GH5 10bit files... Do I still need to apply the [PRE] file in my workflow as my files are now in DNxHD codec inside Resolve? Sorry if this is a silly question, but I'm still trying to truly understand how the different codecs work and where data / video levels come in. Also, when can we expect the V4 update in mail? Or were they sent already and my mailbox blocked it? Quote Link to comment Share on other sites More sharing options...
