Hello Pais,

Welcome to the CDR forum

I'm familiar with the LUTs you've linked. They "emulate" a filmic look for particular cameras. They do not convert clips into RAW (or even fake RAW).

RAW video is shot on some high end cameras and is not processed at all in the camera (it is raw data), unlike your handycam & my cameras. Once a camera processes/compresses the video clip it cannot be made RAW. There's too much data already lost.

I don't have a complete technical comprehension of all that, but that is the way I understand it.

That's not to say that applying the LUTs will not give satisfying results.

PIX thanks for the welcome and for your reply.

I'm no expert so I must have misunderstood this phrase:

" If your camera doesn’t shoot log, or you have existing footage not in log, I have an input LUT that converts video gamma footage into log. [...] Here is the input LUT to convert video gamma into log. I haven’t had a chance to test it further so feedback welcome. Apply it to the footage by selecting it as the 3D Input Lookup Table. Or on the first node of the grade. "

I know that the raw files are not processed (I use them in photography) but reading that sentence I realized it was possible to get a fake raw video.
It seemed strange, but I hoped Messaggio agli italiani che utilizzano PowerDirector , ColorDirector o AudioDirector : http://bit.ly/1rKjrav

Hello Pais,

You're in good company because I'm no expert either!

The technicalities of color grading (at that level) would take many years to understand and apply properly, I'm sure.

In CDR, I applied the LUT from the page you linked - Video2Log_HR_150.cube - and it had the impact you see below. Note the difference in contrast in both the image & histogram.





I'll have to do some further investigation into how that can advantage colour grading in CDR. It's a little beyond me at the moment

On a forum I was told that this procedure does not bring any advantage. I've probably wasted your time

Quote: I know that for optimal color grading are necessary real raw files but I would understand if this procedure may be useful for something.

I use a handycam which does not generate raw files but ColorDirector supports the LUT file.
I found a file LUT that "converts" any video in a RAW video.

LUT : http://juanmelara.com.au/downloads/video2log_lut.zip

I tried to use it with one of my video and the result is in the picture.



I know the video is not a real raw video but It is useful to apply this LUT before doing the color grading?

Hi Pais thanks for the links I just want to edit and make pictures, walk my dog and go fishing.

Hi Kyle. Do you like the LUT file? Messaggio agli italiani che utilizzano PowerDirector , ColorDirector o AudioDirector : http://bit.ly/1rKjrav

I've just had a play with some of my video and the "lut" I've used looks a bit too flat.

I'm a bit pushed for time right now but I've never used "Luts" before and need to find out more about them and how to use them.

Do you know any more links?

cheers I just want to edit and make pictures, walk my dog and go fishing.

The video2log_lut has exactly the purpose of making a flat video.
If you want to try other LUT them are on the same website: http://juanmelara.com.au/downloads/log2hd_cube_luts.zip
I've found others but they are not free

Wow, thank you PIX I just want to edit and make pictures, walk my dog and go fishing.

The problem of the LUT is that they work well only with LOG footage.
Using the LUT with my video greatly increases the video noise

I tried to apply video2log_lut and then I produced the video. To the video product I then applied a second LUT but the result is bad.
Too much information is lost and the quality is very bad.
I think that, in some cases, I will just use video2log_lut

Ps : It would be interesting to apply two LUTs in the same video without having to produce. I hope that this opportunity will be added in the future. Messaggio agli italiani che utilizzano PowerDirector , ColorDirector o AudioDirector : http://bit.ly/1rKjrav

Ummm, had a quick look at some of the LUT's and also a quick read about How to set up and use a Lut via one of the links PIX kindly supplied. It's starting to get a bit too complicated for me and my Panasonic Camcorder if you follow the rules. After a bit of playing around with the settings ( don't we all love that ) I've found I can achieve a good level of effect with just the powerful "curves" , maybe adding a bit of HDR, OR even adding a touch of Shadow Tone can affect a real change in the video.
The most powerful tool I've found so far is "Curves"
The RGB channel has so much to offer, being able to flatten the video image completely OR boost contrast in shadows for instance.
All that and you haven't even touched the Red, Green or Blue Channels.
Just keep a "S" curve in the graph maintaining a "knee" and "shoulder" will give you good detail in shadow and some highlights. If you lift the shadow end of the graph you'll create washed out shadows as in one of the LUTs.
It's all there in one tool

Here is another link to another setting I've just been playing with http://directorzone.cyberlink.com/detail/131623992 .

Cyberlink .... here is an idea , if you can only add the The "Level Tool" found in PhotoDirector, then boy oh boy, what a high end performer you'll have . You can easily change the contrast of the image just by clicking a button Hint Hint

Looking forward to anymore feed back.

Cheers all I just want to edit and make pictures, walk my dog and go fishing.

I did not understand if the LUT is saved in presets.
It seems to me that it is not saved. If I'm right this option should be added.



I tried to create a preset and use it on PowerDirector. It applied all settings except the LUT. Messaggio agli italiani che utilizzano PowerDirector , ColorDirector o AudioDirector : http://bit.ly/1rKjrav
