AVI to MPEG2: GSpot question

[Ennio]

Hi everybody

I'm re-encoding an avi to dvd with TMPGEnc. I "demuxed" audio and video with VirtualDub, because the source avi has VBR MP3. Now to set the right settings in TMPGEnc I ran the avi (video only) through GSpot.
This is what it says:



First question is: what does "BVOP" and "NVOP" (red arrows) mean?

I actually don't know what to think of it. When I run the file in TMPGEnc it's running "judging field order" and sets the source setting to interlaced, bottom field first.

Whereas GSpot doesn't show any fields/sec. It does state 25 frames/s, so I think it's progressive then. GSpot also doesn't highlight "progressive" or "interlaced". Nor TFF or BFF.

My feeling tells me to set the source settings in TMPGEnc to progressive. Concerning the output settings: should I choose progressive? Or interlaced, and if so, TFF or BFF? I wanna convert to PAL dvd as the source framerate is 25f/s.

I'm a little confused now what to do. Can someone help me out?

Thanks in advance

PS Sorry about the bad picture quality; don't know why

It has bframes and packed bitstream is enabled. That is what BVOP and NVOP mean, although XviD can actually do real NVOP's, not together with bframes back then. It was encoded with my build from 2005.09.05. I actually added the date to the userdata of some of my builds.

Sounds like it wasn't encoded as interlaced. Do you see any interlacing lines?

Do you see any interlacing lines?

Thanks for quick reply celtic_druid

What do you mean? Like during playback in media player?

cheers

I don't see them in the player. Don't see them during encoding too (I let TMPGEnc run for a while).

cheers


Edit: I 4 x encoded a couple of minutes with diffrent settings. Source interlaced / progressive and output interlaced / progressive. Authored a dvd with all 4 clips. They all played fine on my standalone dvd player. Strange? Or are these results logic if the source would be progressive?

Weird thang also is that TMPGEnc Plus "said" source is 25 f/s. TMPGEnc 3.0 XPress "said" source is 30 f/s??

cheers
