Sony a6300 test: S-Log2 vs. S-Log3 vs. Gamma Cine4

- I made come comparisons between these picture profiles to better understand their differences. No clear winner, but I'm thinking Cine4 might be better than SLog-2 in lots of situations. See for yourself and let me know what you think!

This is definitely one of the better executed tests I've been able to find on the a6300 comparing it's shooting profiles, so thanks for doing it. The 4 panels right next to each other are an excellent way to compare different modes.
However, I might test your assumptions about the "need" to over or underexpose based simply on the gamma mode you're in. It can change based on the scene and the dynamic range you're dealing with. If the exposure latitude is within the ~6 stops of Rec.709, it's often easier (and easier to be accurate) just shoot in a Rec.709color space.
Having a color (or gray scale) chart that allows you to expose for middle great (for example) helps give you a baseline for comparing shots. I wasn't sure about the "color mode" you were shooting in? That can affect things a lot. For me, Cine4 in S-Gammut3.cine (or Pro color mode) give me the least noisy results with a minimum of tweaking. And I personally wouldn't shoot S-Log2 or 3 in anything other than S-Gammut3.cine because of the little leeway you already have in 8-bit-- but that's just my opinion.
Didn't mean to ramble away. Thanks for the footage. Good job.
cool to have done this. i dont think ISO 800 is native in Cine 4, only in S-LOG. I think it is two stops below that at 200. Your slog shots look underexposed too....it is scary when exposing with slog on these cameras as it looks so awful when shooting but it makes a big difference
+Philip Bloom please make a review on this little a6300!
I don't want to buy a camera without your review!
+AB Palash sorry no more reviews
Happy enough to get your reply! :)
Philip, you've become a heartbreaker, and not in the charming way lol
From what I understand, Cine gives you 10-12 stops of dr while slog gives 12-14. If that's true, then you are only gaining an additional two stops with slog. Of course, in a low-light situation, two stops could be significant, but in most, I don't think that compensates for all the additional issues you have with s-log, including the need to overexpose the footage, shoot at 3200 iso, mandatory grading in post, and the need for ND filters outside. For me, Cine 4 is the best way to go and it still gives you the latitude to do some modest grading in post.
Awesome video and comparison Fabrizio, thank you very much. I recently upgraded my reliable a6000 to a used a6300 and am currently experimenting with slog2 and cine4. Your tests help me a lot. Cheers!
Very detailed testing thanks for this
We have similar findings, for low light or night shots, I do find Cine4 to be cleaner than SLog2. My personal motto is that For a given light situation, if I cannot achieve a proper exposure to the right of 1 1/2 stop at base ISO of 800-1600, I dont use SLog2 or 3, I use regular gamma profiles such as Cine4 or Cine2.
noel falabi so what (if any) advantage do any of these profiles have other than just shooting with no profiles, other than having to grade in post?
Very useful demo. Thanks for that.
Does the +1 etc represent exposure compensation when shot? Sorry i am new.
At 1:57, you can clearly read out the "EDIFIER" brand on the speakers on the control shot without a profile. It's a complete blurry mess on all the other profiles though.
I didn't think s-Log or CINE would remove detail?
Look at the focus on the keyboard/mouse. The focus is different, thats all.
Thank you for the comparison, great! Cheers DrDuu
Thank you so much for sharing this test with us!
exactly what i nee to know!! great job sir!
Thanks a lot.
Thank you, very good tests.
The amount of noise differed because you changed the exposure. It's not due to any differences in the gamma settings. Increasing the exposure decreases the noise.
agreed
great, original video honestly. Thanks
What’s a good gamma setting, if I’m not color grading?
Thanks for your time!
Very nice test! Exactly what I was looking for. However, due to the low bit rate on RUclips, the noise is not easy to compare. Could you maybe make a higher bitrate video available for download?
I do find that when you're indoor Cine4 gives and better and more natural image compared to Slog 2 and 3, you need to set your ISO up a lot and in return much more noise
For my eye, both profile have noise in this test, do you have any suggestion setting to reduce noise?
great test, thank you!
Brilliant tests, thank you.
Very useful, thank you so much!!!
Thank you for the comparison
Any specific reason why you underexposed Cine4?
+Joseph Spruill +1
I actually find it can handle +0.7 without clipping the highlights too much or introducing too much noise in the shadows. Most of the time, the exposure looks correct, since the camera likes to expose to retain highlights a lot.
+Joseph Spruill it tends to overexposed so it's recommended to underexpose by 1 stop to counterbalance it and save some highlights.
@@fabrinaldi it's the first time i hear this...
Great! Thank you for sharing!
So, question 2: What kind of spot metering are you using to arrive at your exposure number? Is it multi, center, or a center spot?
Thank you for the test!!
How are your results with banding in these settings? For me, skies and flat surfaces in shadow in S-Log3 were pretty bad. S-Log2 fixed that a bit, but still not enough to be usable. Also found that I got some purple noise on S-Log2 in the shadows, where I had to go at least +1 to get around it. +2 cleared everything up, but compressed the highlights more.
Also, did some quick testing on the Cines. Cine3 gives cleaner shadows than Cine4, at the expense of maybe 2/3 stop of highlights. They're both a bit noisy in the shadows, but Cine4 is chunkier with chroma noise. Both roll off smoothly enough in highlights, so there's no disadvantage there. And of course, Cine1 has less DR, and Cine2 clips at 100.
+Christian Fiore interesting, I'll test different Cines too, Cine3 might do the job for me. I didn't specifically test for banding anyway, but I had some issues with SLog2.
that will happen because its only 8bit just rubbish 256 value,only way to fix it is shoot with external recorder 10bit, but sony is stubborn neither a7s a7sII or a6300 can output 10 bit, but 2 years old gh4 does.
Interesting test. One question: when you say "color matched" there is a dramatic change in the appearance of the Log footage. What are you actually doing to "color match?"
Color correction I guess
thank you for such speechless but very clear cut explanation but i will oblidge if you answer me slog2 slog3 cine 4 you use belong to which profile i mean p1 p2 ....p9 all the best for your furture projects thank you
Very helpful. Thank you.
Ciao complimenti per il tuo canale.
Vorrei un tuo parere. Ho una Sony a6300. Sto provando sia S-log2 sgamut, Slog3 sgamut3, entrambi mi pare che diano una resa inferiore dei colori in post rispetto a Cine4. Ed inoltre il semplice settaggio Neutro, mi sembra ancora migliore sia in resa colore che in rumore quando li lavoro in post con Premiere Pro... Possibile?
Devi usare DaVinci Resolve per sistemare lo spazio di colore s.gamut...se non vuoi fare questo passaggio usa s.gamut3.cine (ha la stessa matrice del rec709) e alza la saturazione fino a che non rientri nei limiti di saturazione dei colori.
Detto ciò, usando s.gamut e DaVinci avrai i colori più fedeli di qualsiasi altra opzione.
Ciao!
Hi, again very interesting and I've tried it out today, but failed pretty badly, in wondering when you were shooting cine4 what color mode did you use? and any other adjustments to the profile? Thank you
Prompt please, I remove on sony 6300, installation s-log3 is very interesting. It's the settings, I have a problem in that even when shooting a daylight in black objects or shadows there are strong noises, denoiser does not take them out, and I've reviewed how many video tests I've taken on the 6300 in s-log3, there's no problem. A lot of video watched the tests, but little is said about tinctures and everything in English, with a language of complexity. Either that is not what I'm doing, or I'm already sinning on the camera. You can tell what settings you have on s-log3 or show. What is the reason for these noise?
did u fix it?
you have to expose it +2 stops to remove the noise from dark spots
Why is Sony exposure automatic in movie ?
nice job, quite helpfull
thanks for the test!
This test is not accurate, slog2 and 3 should be between +1.7 or +2 overexposed, this is why you are getting more noise in your slog footages, you are then brightening up in post which raise the noise floor of the signal.
Actually slog3 or hlg3 are very close and give you more dynamics range and better highlights, also more room for color grading afterwards
thank you sir
Does the Sony a6000 have any of the s log features?
Lut for the cine4?
you will get always more noise in slog 2... this is a bad comparison
is that -1 +1 gamma?
I'd say it's under/overexposure value.
0:39
Almost no differences.
