Could someone explain exactly when and where the NTSC setup (Y'+16) should be added?
This much I think I know: For NTSC DV, it is supposed to be added at the final analog output, say at the camera when output to TV. To get the same effect when playing on the computer, it needs to be added digitally somewhere in the chain, but preferably near the end. I've also read repeatedly that it should NOT be added before any processing, which makes sense as it pushes Y up against the upper bound. Despite this, from examining output and the code, it looks as about half the software out there adds the setup. kino/smil2yuv (by default) and transcode do, lav2yuv and ffmpeg don't (if I recall properly). What I don't know: When converting DV to mpeg2 (for DVD, say), does the setup get added before conversion, after conversion, or never? Does the DVD player add the setup just like my DV camera would, or does mpeg2 expect to have the setup built it? yuvplay does not add the setup, but should it (or should it be a flag)? I'm starting to understand why everyone hates NTSC...
