    HD2SD Colour

      If I start with a 1920x1080i 4:2:0 HD file and convert it using HD2SD will I end up with a SD file with 4:2:2 or 4:4:4 colour format as that colour detail should exist in the origional HD file.

          It depends on the codec and codec settings you choose when exporting out of VirtualDub.  Lagarith RGB will give you 4:4:4, as will UT RGB.  UT YUV 4:2:2 BT.709 will give you 4:2:2.  Similarly, UT YUV 4:2:0 BT.709 will produce a 4:2:0 file.  Lagarith YV12 is 4:2:0 and YUY2 is 4:2:2.

           

          NB: If you are exporting a final version of your sequence (IOW, not an intermediate file that will be composited), then you don't gain anything by exporting from 4:2:0 source video to 4:2:2 or 4:4:4.  The extra color information wasn't in the source, and it won't be in the export.  All you'll do is waste export time and disk space.
