FREE LUT DOWNLOADS.

CLICK HERE TO GO TO THE MAIN FREE LUT DOWNLOAD PAGE.

Over the years I have created quite a few different LUTs and made them available here for free download. But they are spread all over the website, so sometimes they can be hard to find.  

You can see all the LUT’s that I have included here on XDCAM-USER, whether for S-Log2 or for S-Log3 as well as any articles about LUTs and how to use them by following this link. https://www.xdcam-user.com/?s=luts

But I thought it would also be a big help to have a single page with all of the more popular S-Log3 LUT’s in one place along with samples of how each LUT looks. So, I have created a new fixed page for my S-Log3 LUTs which you can find via the menu bar under the Picture Settings and LUT’s category or by clicking here https://www.xdcam-user.com/picture-settings-and-luts/alisters-free-luts/

Regular readers of the site may have notice that I currently have a couple of new advertisers on board and their financial support should allow me to generate more LUTs going forwards. Any new LUTs will be added to this new LUT page so do keep it book marked in your browser and check back for updates.

Adobe to drop colour managament by default.

14 Comments

I had an interesting chat with Adobe about how they implemented the colour management of footage in Adobe Premiere at IBC. They seem to realise that the way it is implemented by default isn’t very popular, that it isn’t  well documented and not particularly well implemented.  So things will revert back to everything being handled as Rec-709 in a Rec-709 project by default in the near future. This will come very soon (it may already be in the public Beta but I haven’t checked). This does of course mean that once again your Log footage will look flat, which is actually incorrect, Log is not flat, you are just viewing it incorrectly. Those delivering in HDR will have to figure out how to best manage their footage so it isn’t unnecssarily restricted by passing through a Rec-709 project/timeline and most will end up using LUTs with all the restrictions that they impose once again. Perhaps Adobe will return to colour management in the future once they have figured out how to implement it in a more user friendly way.

Adobe still can’t get XAVC levels right!

9 Comments

I’m often asked at the various workshops I run why I don’t grade in Adobe Premiere. Here’s why – they can’t even get basic import levels right.

Below are two screen grabs. The first is from Adobe Premiere CC 2019 and shows an ungraded, as shot, HLG clip. Shot with a Sony Z280 (love that little camera). Note how the clip appears over grossly exposed with a nuclear looking sky and clipped snow, it doesn’t look nice. Also note that the waveform suggest the clips peak levels exceed 110%. Now I know for a fact that if you shoot HLG with any Sony camera white will never exceed 100%.

The second screen grab is from DaVinci Resolve and it shows the same clip. Note how in Resolve that although bright the clip certainly doesn’t look over exposed as it does in Premiere. Note also how the levels show by the waveform now no longer exceeds code value 869 (100% white is 940).  These are the correct and expected levels, this is how the clip is supposed to look. Not the utter nonsense that Adobe creates.

Why can’t Adobe get this right. This problem has existed for ages and it really screws up your footage. If you are using S-Log and you try to add a LUT then things get even worse as the LUT expects the correct levels, not these totally incorrect levels.

Take the SDI or raw out from the camera and record a ProRes file on something like a Shogun while recording XAVC internally and the two files look totally different in Premiere but they look the same in Resolve. Come on Adobe – you should be doing better than this.

If they can’t even bring clips in at the correct levels, what hope is there of being able to get a decent grading output? I can make the XAVC clips look OK in Premiere but I have to bring the levels down to do this. I shouldn’t have to. I exposed it right when I shot it so I expect it to look right in my edit software.
