Problem with color when rendering a video
Hi all.
Sorry about my english. Its not my primary language.
Here is the thing: I have an video in mpeg4 avc. When I open the video in kdenlive just to export it using the same codec (its an test), the end result is that the image of the video is resulting in lower contrast and lower colors intensity.
Just for informative: When I reencode any video in "avidemux" with the default setting i get exacly the same problem but in avidemux I have an option to encode using "Full Range Samples". When I check this option and encode any video the end result is that the video has the same colors as the original, so all perfect. On kdenlive I coudnt find an option like that to solve this problem.
In shotcut I have the same problem but there is an option where I select "Color Range: FULL (JPEG)" and the problem is solved for any video I encode there.
Well, I dont know if I make myself clear on the explanation. I hope so.
Does anyone understand whats going on and how to solve it in kdenlive?
Ps.: The things I need to do with my videos I can do in shotcut without problemas but Im really impressed with the easy to do some stuffs on kdenlive that I would like to move all my workflow to kdenlive (with some other softwares) but if I cant solve this issue its a no go for me.
Thanks anyway and sorry to be dumb on this subject. Im new to video editing.
Ps.: Tested with 5 different videos and the results are always the same as explained in the pictures and the videos rendered in kdenlive and shotcut. I uploaded the tests with one video that I cutted from my live podcast. Please, ignore the audio and look at the colors.
The problem occurs in the previous edition of kdenlive and in the newly released one (22.12.0). Didnt try it in old versions.
My setup:
AMD A8 7600 8Gb RAM Radeon RX 550 Windows 10 22H2 pro updated Latest vga drivers from amd All updated I have other softwares installed: Adobe Photoshop, AfterEffects, Kdenlive, Shotcut, Vegas Pro, Blender, Krita, Gimp, Avidemux, lav filters, fmpeg latest stable, and some other softwares for multimidia creation and edition.
