Hey everyone. I'm not sure if this is a compression problem or more just a problem with the codec used. I'm compressing to FLV's 320x320 w/ 200kbps. The problem that I'm getting is only with red colors. The edges of red objects(ties, shirts,etc.) all have very jagged edges. The video was captured HDV 4:2:0 I believe via Canon XH-A1 firewire 1440x1080 30i. Are the edges from the HDV or from FLV? Like I said, no other color has this problem.
Red text,red graphics and just the color red in general is notorious for bleeding and generally looking like crap as resolution and color depth decreases. It's also possible that the saturation is too high on he original material We always keep reds to below 75% saturation (as measured in photoshop) on any text and graphics, and typically at 80% or lower on luminance in the original graphics.
We also use red sparingly as a text color or text edge.
