John Meyer suggested to me outside the forum that this is affecting 60i material only, so I did some more testing and that looks like that’s the case. My previous tests were just on 50i material.
Here’s the testing I’ve done so far, also showing which ones John Meyer has so far confirmed:
Everything at Best (Full) preview
Everything “Interpolate fields”
MPEG2 template I used was “DVD Architect NTSC widescreen”
8.0c
Preview of nested file – OK
PAL DV to PAL DV – OK
PAL DV to MPEG2 – OK (Confirmed – Meyer)
1080-50i HDV to SD MPEG2 – OK (Confirmed – Meyer)
1080-50i AVCHD (made from HDV) to SD MPEG2 – OK
1080-60i HDV to NTSC DV – OK
1080-60i HDV to SD MPEG2 – OK (Confirmed – Meyer)
10.0e
Preview of nested file – OK
PAL DV to PAL DV – OK
PAL DV to MPEG2 – OK (Confirmed – Meyer)
1080-50i HDV to SD MPEG2 – OK (Confirmed – Meyer)
1080-50i AVCHD (made from HDV) to SD MPEG2 – OK
1080-60i HDV to SD MPEG2 not via nested project – OK (Confirmed – Meyer)
1080-60i HDV to NTSC DV – NOT OK – renders progressive
1080-60i HDV to SD MPEG2 – NOT OK – renders progressive (Confirmed – Meyer)
1080-60i HDV to SD Lagarith – NOT OK – renders progressive
Nasty bug which must have caught out a lot of people.
