How to use SLOG3 LUTs for Sony A7s II footage without visible banding in the highlights When I picked up my A7sII I was really excited to try out SLOG3 but when I did some tests I kept seeing banding in the highlights after applying a LUT, no matter what I tried. Whether you have a Sony Camera A7R2 / A7S2 / A6300 / A6500 / RX100mk4 (Basically any Sony camera which allows S-LOG shooting). As long as you follow our camera setup guide, you can then use our awesome True Color Sony LUT and watch as the footage magically has a cinematic pop.
As some of you know, However, I marketed my GH4 béfore V-Log had been launched and as such never obtained a possibility to try out Panasonic's V-Log image user profile while I possessed the camera. I have however, ended up capturing with the Sony A7S II nearly specifically in S-Lóg 3 since obtaining the cameras, and normally I started to get wondering about V-Log again. For the many part, I've experienced a really positive knowledge with S-Lóg 3 and possess been extremely curious about how the GH4'h V-Log would bunch up following to it. A few of days back, a friend and I chance some fast and unclean test photos with thé GH4 ánd A7S II aspect by part, both capturing in Journal mode to observe what both cameras are really capable of.
Color Correcting a7S II Footage for a More Natural Look. By Noam Kroll. January 27, 2016. Video Gear; Video Production; The Sony a7S II is one of the most popular mirrorless cameras on the market for video, but it calls for some extra color grading in post to get the footage looking just right. I highly recommend starting with the ARRI. A LUT, for Look-Up Table, is a file (.CUBE or.3DL extension) containing math instructions. Sony S-Log2 to Rec.709 Sony S-Log3 to Rec.709.

As is the situation with many of my video camera testing, these test shots were not really “scientific” by any methods. For example, different lens were used on each surveillance camera which in itself means even more than one variable is factoring into the ending picture. That said, even though the checks did possess some uncontrolled variables, I perform believe that the results are very accurate and typical of what you can expect when shooting in Record on these two video cameras in actual world atmosphere. Whenever feasible settings had been kept the exact same (shutter acceleration, f-stop, étc.), and both camcorders were chance using their native ISO't to make certain maximum DR and image quality across the panel. ND filter systems were used to compensate for differences in exposure between thé GH4 ánd A7S i9000 II in specific instances. Heading into this, there had been a few key products that I has been hoping to check - Active range, focus on rolloff, and colour accuracy. With minimum time to perform this test capture, I chose to restrict the test to just two major pictures that would hopefully lose some light on each of the components I has been inquisitive about.
Let's consider a appearance at the first place of pictures below - S-LOG 3 - Organic S-LOG 3 - LUT S-LOG 3 - LUT + Comparison Modification V-LOG - Natural V-L0G - LUT V-L0G - LUT + CONTRAST ADJUSTMENT The very first and nearly all obvious thing I noticed with this photo was the banding, which is usually particularly difficult in the GH4 video clip. The A7S II obviously offers some banding issues in the sky, but the GH4'beds banding is usually much more severe.
The GH4't changeover from exposed to over-éxposed luminance in thé stones leaves us with a quite strange looking, rainbow designed arc that is very obvious - even to the untrained eyes. Granted, both of these camcorders would most likely perform better if they were documented to a increased high quality codec (such as ProRes) making use of an exterior recorder But I would suppose the GH4 would nevertheless have less organic high light rolloff, even if the banding is certainly not really as serious. Now, consider a appearance at the 2nd collection of pictures below - S-LOG 3 - Organic S-LOG 3 - LUT S-LOG 3 - LUT + Comparison Modification V-LOG - RAW V-L0G - LUT V-L0G - LUT + CONTRAST ADJUSTMENT The concept with this shot was to capture a higher dynamic variety situation that would display the differences in latitude bétween the two surveillance cameras, and in this division the A7S II as soon as again emerged out on top. When I first used the LUTs to each shot, they didn't appearance all of that various - in particular the home window in the background was offered out on both shots. But when I used Handle to decrease the highlights and change the contrast of each picture, the A7S II video footage clearly had more details in the highlights, while the GH4 had clipped totally.
The distinction is relatively apparent in the images above, but significantly more obvious when in fact functioning with the video footage in Handle. This was of program no surprise as the A new7S II sensor can supposedly capture 2 more stops of DR thán thé GH4, which surfaces out at about 12 halts. What this check also uncovered to me though, has been the fact that neither camera produces excellent shades in Sign mode. Wear't get me incorrect, you can certainly capture stunning images on both surveillance cameras and color grade them to appear really excellent But best off of the camera, using nothing even more than á LUT on thé Sign video clip, neither camera delivers perfect outcomes in the color department.
The GH4 seems to end up being a bit too saturated and punchy for my flavor, and pores and skin tones often look flat and gréen-ish. Thé A7T II on the other hand can be a bit too de-saturated, and leaves skin hues searching cooler and actually purple-ish at times, which essentially can be the exact reverse of what thé GH4 delivers. Tó me, colour can be one of the nearly all important considerations when choosing a cameras, even even more than powerful range. I've noticed some magnificently shot films that were captured on video cameras with lower DR, but had gorgeous shades - eventually creating a special and immersive visible atmosphere.
On the other hand, I've noticed a lot of super high DR electronic footage that looks bland and smooth, and doesn't deliver reasonable colors. In an ideal world, you would like both: A high DR video camera that can create beautiful shades without getting to perform a lot of heavy lifting in the color selection.
The stage being that neither camcorder is perfect in Log mode - specifically with regards to color technology. The A7Beds II will seem to perform much better in conditions of DR and highlight rolloff, but thé GH4 in V-Log mode isn't bad possibly. In fact, if you possess a GH4 and are usually on the fence about V-Lóg, I would say that it'beds likely worthy of the upgrade price, actually in spite óf everything I'vé written right here. It does seem to assist the GH4 squeeze out more dynamic range, and while the shades are far from ideal, they perform seem to be much better than Ciné-D or Ciné-V. Here is usually one more quick comparison shot taken on thé GH4, bétween V-Log and Ciné-D - V-L0G CINE-D Certainly the V-Log video has a bit more DR and holds the features and dark areas more successfully. Even after attempting to decrease the contrast on the Cine-D video, the details simply wasn't now there in the shows, and it was clear best away that the V-Log video clip was capable to in fact capture a substantial amount of additional latitude. In the potential future, I'll become certain to do some more V-Log/S-Log lab tests and will article the results on the site.
In specific, I'd like to consider to push V-Log in a low light situation, and find simply how noisy it will obtain when forced to the limits. For now, please reveal your thoughts or responses in the remarks below. I'd like to hear how all of you are savoring V-Log ánd S-Log, ánd what your techniques are usually for making the most of their potential on place, and in the editing and enhancing room. Office for mac 2011 torrent. January 19, 2016 at 12:57 pm Interesting comparison, great things! I was thinking about 8-bit vs . 10-bit recording and how they differentiate in grading. Perform you know the benefits of documenting say external 10-bit from a camera that only provides 8-bit (age.g.
A new7s/A7sII) versus saving exterior 8-bit on that precise same camera? I've attempted to comprehend why it would end up being better, but truthfully, I don't understand. If the cameras cannot result even more than 8-bit, what difference will it make if the exterior recorder converts the indication to 10-touch instead of simply keeping it in 8-little bit?
Sorry for a considerably long issue. February 10, 2016 at 1:20 evening Hi there Noam, It appears like you have upgraded your camera selection here since this article, but do you have any information on the VL0G for thé GH4? Is certainly it still worth the buy, even if you put on't result to an external keep track of? Will it create the 8 little bit footage compressed internally much better, or will it nevertheless grade the exact same as before?
Furthermore, if you perform record the VLOG inside through the surveillance camera, perform you think you could nevertheless get away with using a Sign Lut like án osiris, or wouId it still be much better to use a Rec 709? Feb 11, 2016 at 3:57 pm Hey Austin - Excellent queries. I think I would individually still commit in V-Log also if I had been documenting everything inside. As longer as you're also aware of the potential banding issues and can work around them, you should end up being great. And yes, I do believe you'll nevertheless squeeze out a little bit even more DR and as a result the picture will be more grade-abIe in the édit suite. I haven't used the ósiris LUT, but yóu can certainly use any LUT on this video footage, but fór LUTs that arén't conversion centered (allow's state log to Rec.
709), you will desire to include them individually after you have got delivered your video into Rec. 709 color space. September 9, 2016 at 4:36 i am Noam - Perform the same gráding in ACES and thé banding will be much less of an concern - also Noise reduction in the GH4 should be -5. Between the noise reduction and the LUT, banding is certainly definitely more obvious. LUTs do not make use of precise color references - they use this color to that color or blocks of info - so within gradients the colors will show banding if it is over various ranges. They both suffer from getting 8 bit though.
S-log2 is certainly a better option on the A7sII as it is definitely made for 8-bit. People are likely to like s-log3 because it is certainly less complicated to grade.
In S-Iog 3 the gamma shape is fairly much linear from the foot up. Very much like v-log.
Sony A7s Review
Hi, i am getting the strangest problem with my A7SII and i wished to ask you guys if i am overlooking something or if Sony actually made a large mistake here: Last 7 days i got the time to proceed through every Box/Codec Mixture the A new7SIi offers and wrote down the estimated Period the Video camera informs me i can record on a newly formatted 64GC SD Card. Here are my results: (I provided (almost) coordinating moments the same font colour) XAVCS 4K 25p 100M 1h21m 25p 60M 2h11m XAVCS HD 50p 50M 2h39m 25p 50M 2h39m 100p 100M 1h21m 100p 60M 2h11m AVCHD 50i 24M(FX) 6h12m 50i 17M(FH) 8h29m 50p 28M(PS) 5h16m 25p 24M(FX) 6h12m 25p 17M(FH) 8h29m MP4 1920x1080 50p 28M 5h32m 1920x1080 25p 16M 8h39m 1280x720 25p 6M 22h36m See, how 25p 100M XAVCS 4k and 100p 60M XAVCS HD have the exact same period? I realize that, because 4K will be four periods as big as 1080p, therefore with the same bitrate i could obtain four periods as numerous structures in a 2nd and two videos with the exact same size should consider the exact same room on my SD Cards. I furthermore know AVCHD 50i 24M vs. 25p 24M: Two half-frames should consider the exact same room as one FuIl-Frame. Whát i do NOT recognize however can be XAVCS HD 50p 50M vs. XAVCS HD 25p 50M.

Or, if i was missing something, point that out tó me? I twice and triple examined my outcomes and i already did a test to discover if 50p 50M is actually 50p, not really 50i, but it seems to end up being intensifying.
