I’m trying to find a way to set the black and white point in a video. Normally I would do this using the histogram or the levels, but histogram is still on the roadmap and I couldn’t find a levels filter.
Is there any way in ShotCut to set the white and black point of a video with another filter?
Regarding the black point, I’m not sure I’ve never actually set that although these will all adjust your visible colors.
Regarding the white point, specifically in photography color temperature and white balance are used interchangeably, I typically balance my camera to my lighting first so I don’t have to change it in the editor however(which is easy when I know my lights are 5500k I can just set my camera to that)
I’ve been using the “Neutral color” feature in the White Balance.
I invested in an 18% Gray card - less than $10 on eBay or Amazon or Walmart - and include it in my shots, at the beginning. One click on the image of the card, and Shotcut adjusts both color and brightness as if by magic.
To the O.P.: I don’t know what you’re trying to accomplish that the lift and gain controls won’t achieve.
Shotcut’s White Balace filter is very useful.
With the addition of the new Levels, Hue/Lightness/Saturation controls, Shotcut’s UI is starting to look pretty butchered up with a lot of redundancy and nonstandard nomenclature.
In order to set gamma properly you need a test chart with 90% white 18% gray and a properly-calibrated scope. Unfortunately Shotcut’s video scope lacks graticule lines so it is not suitable for this purpose.
This spreadsheet relates reflectance to video levels, and there is a link to the test chart I use.
The fun begins when we get into HDR. HLG is just the beginning. I don’t even want to think about PQ.
I took a video on a black background, but the background didn’t appear completely black in the video. Coming from photography, the easiest way to darken the background in a photo is the levels tool (some other tools like the curves tool also do the job). So I was looking for something similar in ShotCut. With the new levels tool it is now quite easy to achieve a completely black background. There may be other ways to achieve the same effect, but I didn’t find them.
Anyway, thanks a lot to the developers which did such a great job.
