hi anthokio, thanks but videos are generated by computer and i have checked: my black is a real black so this is more a problem of graphic cards than sources trouble.
i cant afford in time and ressources to level up or down all materials. this is really a weird thing.
when i output a single black video, i have this result:
the videos are generated by final cut and sony vegas on different machines, so i m pretty sure this is a setting things not ok.
yep founded, unfortunatly i m already full range 0-255 for my two monitors ( rendering and main patching)
about amma: this is yes a gamma issue if i insert a levels node as antokhio suggested, it will kill the grey effect. But my main problem is that all my patch is based on texture added on the top of each other. So i cant use levels because i have too many sources different to mix together.
yes. if i put the footage inside vegas, and make it little, i have a complete real black
this happens also on filetextures. i m working with a traditionnal cartoonist wich is producing its animation on black paper. So i dont have png with transparencies. its very strange.
hi cat. well its not enough the gamma cheating in nvidia to obtain a real black.
The problem is not just the general output. The probleme is that each quad is interpreted with a higher level of black, and so adding multiple quads supposed to be black is a nightmare.
the problem persists also with dds textures coming from importation of drawings from a mac
yeah, the problem ist most definitely wrong gamma and or clipped “tv safe” colour ranges.
you should really have a close look on your source footage to find out more. (e.g. colorpick a “black” from it to get some insight on actual pixel values) also check all hardware settings like joreg and catweasel suggested.
edit: this is a classic mac <-> pc content pipeline problem which i encountered numerous times. (all because apple engineers picked the “wrong” gamma at some time in the 80s to make black and white output look right on the first laserwriter. doh…)
ok. problem is that i m converting mov with vegas. so im dead on all the line.
dont have mony to buy a premiere where i have invested in sony. :-(
at the end my black are 17 value.
i will try to write a little shader just to cut down blacks with a threshold value.
many thanks !
