When I apply the broadcastcolors output effects filter, the histogram shows the output clamped properly, (everything shows up in the safe areas and out of the left and right shaded areas).
But, when I render using MainConcepts MPEG2, (using NTSC-DVD template or others) the resulting rendered clip is still out of the 16-235 range. The video levels have been reduced, but are not completely in the safe range, as they were before the render.
The same result when I render to AVI compressed. However, when I render to AVI uncompressed, the render has been successfully clamped into the safe areas of the histogram.
So far, the only workaround I have found, is to apply the levels filter first in the output FX chain, and set the output start and end points, the end point set to around 0.92 for example. Then apply the broadcastcolors plugin to clamp. But this workaround effects non-problemed shots in a negative way.
This project has many video clips of a computer screen, shot by sending the video cards s-video output directly into a sony VX2000 camcorder. In hindsight I should have brought the levels down at the time the tape was rolling. The levels on these scenes are way out of range. So much so, that, even with the broadcastcolor clamped renders, a DVD player connected to a TV via composite RCA jacks will start to cycle the hues. (if the DVD player is connected via s-video or component cables, the problem goes away.....I have tested this on two DVD player and TV sets).
Anyone else ran into this problem? Any thoughts on better workarounds?
Sorry for such a long post, thank you in advance.
