S-Log3 vs HLG3 with 8-bit video on a Sony a7iii 

Thank you very much.

Hello. Yes the HLG3 really looks good and the colour rendering is amazing. Thanks for the comment. Cheers!

Hello. Thanks for sharing. Cheers!

That was what I wanted to ask exactly in the above comment. So; by underexposing a little, you recover shadow details efficiently and do not need to use nd filter. Am I right?

Well an ND filter is used to slow down the shutter speed to 1/50s and not overexpose the shot. It's a necessary item in a midday shoot.

Hlg3 wants to be exposed much darker than most other profiles. Middle grey is all the way down at 21%. However I tend to expose middle gray somewhere around 28% just to give a little more wiggle room in the shadows.

Hey thanks a lot. I really appreciate it. Cheers!

Hello. Thanks a lot and welcome to the channel. Cheers!

Hey! Thanks. I really appreciate it. Cheers!

What can we consider buying instead of a7iii in this case?

I would highly recommend the a7IV. Way better in everything when it comes to video. Cheers!

@@M1R0_Life_through_a_lensAnd way too expensive too, pass 😂👍

Yeah!@@danielmihaylov5525

Hello. Yes it works really well with 8bit. No need for Slog3. Thanks for the comment. Cheers!

Thanks a lot. Will do. Cheers!

Hello. Slog3 on an 8bit camera really only works if the scene is really bright and most of the details sit in the highlights. Otherwise the lack of colours make the image fall apart. Log should really be used with 10bit colours. This is why HLG looks better with 8bit. In any case if you want to do some colour separating in post, 8bit will not be good enough. Especially if the scene is mostly composed of shadows. Thanks for the comment. Cheers!

Hello. Will do. Cheers!

Thank you very much. Cheers!

Hello. Set the picture profile PP10. You can also edit every picture profile manually. Cheers!

Hello and thank you for the nice comment. I'm actualy using th Rec.709 color space because my videos are for RU-vid and the Rec.709 is the standard. But in order to get here I have to do a color space conversion, so: - recorded color space (CS) in camera is BT2020 (Rec.2020) - editing timeline CS is Rec.709, Gamma 2.4 (good for monitors and mobile phones) - color space conversion is done in Davinci Resolve using the Color Space Transform tool where I just set the input CS to BT 2020 and everything else is left the same as the timeline, so output CS and Gamma ==> same a timeline. Input gamma is also same a timeline because HLG is a hybride gamma. - I do a basic exposure adjustment - before the Color Space Transform node! - export video... I hope this helps. Cheers!

@@M1R0_Life_through_a_lens Wow thank you so much. I am worried if I have my timeline set to Rec.709, it might compress the colors too much.

@@VeeTravels If the timeline is set to Rec.709, then you see how the end result will look like, if you export in Rec.709. If you are working on a HDR export, then you need a timeline color space with a wider gammut but you also need a HDR monitor to actualy see it. Also if you have video clips that were recorded with a wider gammut, then it makes sense to have a wider gammut timeline just remember that the end result will be in Rec.709.

My goal is to have my videos exported in HDR onto RU-vid so I do not think exporting in Rec.709, Gamma 2.4 will allow that capability. I think exporting in Rec.2020 ST2084 will allow HDR to be detectable on RU-vid. Do you think it will be better to convert my timeline to Rec.709 for proper editing using my SDR monitor or would it be better to use a monitor LUT?

Aaaa OK. In this case you should have the time line at least 2020 or the same as your export colour space. I think you will have to use a hdr monitor for this otherwise you don't see how the end result will look like. Cheers!

Ha! Would love to have it on a7iii. Thanks for the comment. Cheers!

Hello. Thanks for sharing. I typically don't have problems with HLG but hey. Cheers!

Hello. It does look good especially on an 8bit camera. Thanks for the comment. Cheers!

Hello. A video is on the way 👍

@@M1R0_Life_through_a_lens cool 👍

Hello. On my A7III I use the HLG3 with bt.2020 which is under PP10. It's the best dynamic range vs. colours. Other settings are 1/50s SS, 125 ISO and f2.8. In most cases I use a variable ND filter for this to work. Also make sure to have the proper white balance set. 5500K is neutral. Thanks for the comment. Cheers!

@@M1R0_Life_through_a_lens Hi, very good video. Do you use zebra level and how much?

@@antonioathanasiadis3307 Hello. I typically use 55 for the midtones.

Hello. It depends on the brightness of the scene and your chosen aperture value. In midday sun with f2.8 an ND will be needed. Thanks for the comment. Cheers!

Hello again. Set it to the lowest point for best quality.

Hello! With a7iii it's HLG3. Just looks better with 8-bit. With a7iv S-log3 and 10bit. Thanks for the comment. Cheers!

Hello. Interesting. I've actualy never tried the PP off ;) Will give it a try. Thanks for the comment. Cheers!

​@@M1R0_Life_through_a_lens Don't forget reduce highlights from 109% superbrights. It gives you +1 stop. But again it is bt.709 gamut with magenta shadows and gain spherical aberrations.

i shot my first video on sony a7iii and hlg2 but i chose 709 - do you think i will have issues grading the footage? also, does a7iii have a native iso for HLG3?

Hello. The bt.2020 has a larger gamut so more colours to choose from. I'm not sure if it makes a big difference with 8bit recording. The a7iii doesn't have a dual native ISO so try to keep it as low as possible in any PP. Thanks for the comment. Cheers!

Just create rec709 timeline, put your clip on it and apply "SDR confirm" plugin.

Thanks for the comment. Cheers!

Sorry about that ;). Thanks for the comment. Cheers!

Also I should mention, clipping point in S-Log2 or 3 on minimal ISO is the same as the clipping point on minimal ISO in HLG or any other profiles, the only thing that changes is your shadows and middle gray exposure. So, if you shoot in HLG without clipping on minimal ISO and your face is slight underexposed then you shoot in any sort of Log, then your face will be exposed closer to correct middle gray exposure and you will see less of color or compression artifacts and the same amount of noise.

Hello. Thanks for the info. Yes the Slog2 is a better choice for 8bit. Honestly HLG vs Slog2 is pretty much the same just the colours render out cleaner with HLG. I appreciate you stopping by. Cheers!

Hey! Thanks for sharing. Will do it better next time. Cheers!
