HC's manual says
Quote:
*COLOUR
parameter colorimetry type integer
Status not required
Default -
Example *COLOUR 5
This command flags the colorimetry of the stream by outputting the Sequence Display Extension
header. For playback this header is ignored (Rec.601 will always be used for SD color
conversion, Rec.709 for HD color conversion) but it's useful for MPEG2 compliancy.
Possible settings: 1: BT.709, 4: BT.470-2M, 5: BT.470-2BG, 6: SMPTE170M, 7: SMPTE240M.
By default this header is not written.

and I'm no wiser on whether HC detects incoming colorspace and converts it automatically or not.

Well well, I just checked a couple of recordings with DGindex and PAL HDTV 1080i (after a VideoReDo Quickstreamfix) comes up as "
BT.709*" and PAL SD 576i comes up as "
BT470-2 B,G*" ...
Till now with SD I've been simply using .TS -> VideoReDo QuickStreamFix -> straight into a DVD author program without any recoding/tinkering and it authors/records/plays DVD OK. Wonder what it's doing ?
With HDTV the steps were .TS -> VideoReDo QuickStreamFix -> DGindex -> Avisynth to SD size -> HC -> author to DVD so I wonder what colourspace it ended up as on the DVD (and whether it's right).
EDIT:
http://forum.doom9.org/showthread.ph...92#post1060292 says "DGIndex won't show Rec.601 unless there is a sequence_display_extension() calling it out. If it is missing, DGIndex assumes Rec.709 (as it should)." so I'm not sure if that's of much help then... I'm not sure if there's any rec.601 or not
