MPEG2 poor quality vs DV from MiniDV in AVI

[colineddy]

Hi,

When I download avi from my MiniDV camcorder using Pinnacle 10 I get superb quality when the file is played back on my PC using any media player.

However when I compress to MPEG2 and play the file back I really see the horizontal lines from the 720* 576 resolution.

Any ideas ? I want to compress the video but I don't want to loose the quality (I guess if I knew the answer I'd be richer than I am now)

Interlace. Play it on the TV, and they go away, or use a player that do deinterlacing properly (PowerDVD?)

Those interlace comb artifacts are in your DV AVI file too. Microsoft's DV decoder and Windows Media Player are hiding them from you by performing a BOB deinterlace while playing it. So, as mats.hogberg said, all you need to do is use a player that will deinterlace while playing back the MPEG2 file. Media Player Classic and VLC both support deinterlacing during playback of MPEG2 files. You have to manually enable it though.

Thanks - sucess comming I think....

I have Windows Media PLayer CLassic from the Klite Mega Codec Pack 1.54 beta.

I cannot see the switch in the options to turn on de-interlacing but the picture quality seems better that with regular media player.

What about my TV / DVD Player - does that have to be capable of de-interlacing ? It won't play plaing mpg files, you have to author them are a DVD...

Media Player Classic uses its own MPEG2 decoder and the decoder has the deinterlacing options. To enable deinterlacing start playing an MPEG2 file then select:

Play -> Filters -> MPEG2 Video Decoder

From that dialog select the deinterlacing option you want. I prefer BOB.

If you have a standard-def TV, it is designed to handle interlaced video. Assuming the field order is correct, interlaced video will display just fine. If you get the field order wrong, your video will appear to jump on the TV. Restream can change various flags without re-encoding, and field order is one of them. Then you can reauthor and burn again.

I cannot speak for HDTV as I don't own one.
