Hi,
I'm trying to capture a home video. Recorded on a Panasonic NV-A1 camera(analog), which I would like to capture in 480x576 (PAL). Will use it to make SVCD.

Can I expect interlacing artifacts and if so how do I get around it.
When do I apply filter and which one and with what settings.

Pls keep them answers simple so I can understand it.

Thx

When I get interlacing artifacts I use Donald Graft's Smart Deinterlacer at the default settings.

But it you resize to SVCD's 480x480 from 480x576 you may not need deinterlacing.

Use the Matroska file format

Thx for your reply, but..


I'm using PAL all the way. Thus the final SVCD will be 480x576.

And i'm actually more curious to know if there will be interlacing problems.

I think the home made tape is progressive and I know my TV is interlaced so will there be interlace artifacts?

Interlaceing is somekind of compression always used on television. It allows 50 half-frames per second, so that fast motion doen´t rumble and low motion is displayed at full resolution.
You can yust leave the interlacing artifact on PC as they are, but you have to tell your mpeg-encoder that the source is interlaced, it will produce an interlaced video anyway and your TV can only display interlaced, so you degrade the quality by removing this artifacts, because you have to use it anyway.
