Questions about commercial DVD format

[Flav_cool]

Didn't know where to put this...I found this section to be the most suitable.

1) Commercial DVDs, like a movie you would rent from blockbuster, is it progressive or interlaced?

2) If interlaced, how come when viewed on the computer you don't get the interlacing edges like when i watch DV video from my camcorder (also interlaced)?

Thanks,

1) Commercial DVDs, like a movie you would rent from blockbuster, is it progressive or interlaced? Both. Movies are usually progressive and tv shows are usually interlaced. But it can also be the other way around.

2) If interlaced, how come when viewed on the computer you don't get the interlacing edges like when i watch DV video from my camcorder (also interlaced)?Because software DVD players deinterlace the video.



EDIT: If you you playback your DV clip using the MS DV codec included in DirectX 9, you should not see interlaced lines. It deinterlaces it if you have vmr-9 enabled and your video card overlay supports it.

I do have VMR9 enabled and use ffdshow...hmmm Still looks bad and if i enable the resize (like i usually ahve for divx and dvds, it gets laggy)

EDIT: actually, doesn't look as bad as in premiere...but still doesn't look as good as a commercial dvd... (You can still see the interlacing lines on edges a bit) (Perhaps try different deinterlacing method within ffdshow?)

Use the MS DV codec, not FFDShow.

[Flav_cool]

Which part of ffdshow should I turn off? ...(Would it have to be enabled first under deinterlacing for me "not to use ffdshow" or does it automatically use it's codec?)

[Video Dude]

Disable "dvsd" in FFDShow.

Since FFDShow will now no longer decode DV, the default sytem codec will take over which is the MS DV codec.

You don't have to change any other settings is FFDShow. Once you disable "dvsd", FFDShow will no longer be used for DV.
