Which cards can capture above 384*288 noninterlaced

[SovA_SovA]

Hi
I have a Hauppauge WinTV pci card which can capture in any res up to 768*576, but my problem is that the picture becomes interlaced when the res is above 384*288.
Which cards can capture in res. above 384*288 without interlacind the picture and don't cost a fortune (not DV/firewire cards)?

Greetings SovA

You can't capture above x288 without the capture being interlaced. PAL (and NTSC) TV *is* interlaced video. You will have to capture the video, and then deinterlace it later. If you have a fast PC and use Vdub, you can deinterlace during your capture.

Interlacing isn't a defect. It's a feature of the source material. Video cameras, including DV, almost always produce interlaced material. Only film is progressive. Telecined film can seem interlaced in both PAL and NTSC, but there are tools for handling that.

It is possible to make interlace lines disappear on a progressive computer screen by using doubled field rate, but captured video has to remain interlaced or one of the following will happen:

1) Both fields are stored as full-sized frames - storage requirements will double.
2) Interlace lines are removed using a good algorithm - temporal resolution is halved.
3) Fields are stored as individual frames - spatial resolution is halved.

That's why the best option is to keep full-sized material interlaced and encode it to a format that supports interlacing, such as MPEG-2. Most players can once again double the field rate for playback and display it without artifacts.

I thought that PAL signals was x576 lines and not x288, but thx for the answers, I'll work on it. Do you know where I can get a free mpeg2 codec?

DivX4-codec can deinterlace during capturing... quality ain't the best, but decent.

There is no free codec that could actually encode like the name suggests, so you have to use an offline encoder for that.
