Progressive sources -> Interlaced encode?

[ZQX]

Eeek have I stuffed up? I just encoded a bunch of flv's & mp4's (Youtube etc) to DVD using HC Encoder, and I've just realized that HC is set to "Interlaced TFF"! Should I have set it to "Progressive"?

[gadgetguy]

Probably, but what was the framerate of the source? And is the Moon NTSC or PAL?

[manono]

And is the Moon NTSC or PAL?

Hehe, yep. If PAL 25fps or NTSC 29.97fps, no problem. If NTSC 23.976fps, then it makes a difference and they should have been encoded as progressive with pulldown applied afterwards.

what is the final output supposed to play on?

[ZQX]

Ah ok thanks, I think I may be ok. The stuff I've already encoded have been 25fps clips. I'm encoding to DVD to play on my analogue TV.

I'm using some pretty heavy-duty avisynth filtering and encoding can take up to 24 hours, so I was panicking when I realized I had encoded as "interlaced", but I think it's all OK.

Encoding progressive video in interlaced mode will result in a little unnecessary blurring and artifacting of the chroma channels. You probably wouldn't even notice if it wasn't pointed out to you.
