While following this thread and experimenting on my own, I stumble on something... When I apply the inverse video plugin, I dont get the same result if my project's color model is RGB or YUV. It seems as if the plugin simply reverse each channel without considering if the color model is RGB or YUV. If your color model is RGB then the plugin work right and each chanel/color is inverted. However if your color model is YUV then the first channel is Y and it get inverted if you select the "invert R". Finally if you invert all three channel RGB you get the same result whether your color model is YUV or RGB. Looking up in the invert.c I'm suspecting that when the color model is YUV the plugin does not provide a conversion of YUV to the RGB before applying the plugin or a conversion of the effect from RGB to YVU to appy to the YUV stream. Can anyone confirm? On an other note ( I could not find the C41 thread) I manage to make picon_png.h file for use in a plugin by coping the pngtoh.c form the guicast directory to an other directory. Build it with gcc pngtoh.c -o pngtoh.o made pngtoh.o executable, and used pngtoh.o picon.png to make the pngtoh.c file Félix-A. _______________________________________________ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
