Interlace or Non-Interlace whichy to use?

[majunbubu]

I hope I am posting this in the right group but my quesiton is as follows:

I am using TMPeng Plus to encode a raw avi I grabbed off of cable tv NTSC (US) feed using my Hauppauge card at a resolution of 480x480. When encoding what should I set the encode mode to on the Video tab and the source tab as when I want to create an SVCD? Interlaced or Non-Interlaced? Any help or information on this would be greatly appreciated.

Thanks,

It depends on what you capture. If it's a movie choose do a inverse telecine to convert 30fps (60 fields p/ sec) to 24 fps and then encode with the 3:2 pulldown flag active) if you captured from a tv show a or somethin live etc... choose interlace to get the 60 fields. If you choose non interlace in these sources the motion won't be as smooth.

Thanks, I have been encoding in non-interlace and the motion looked like crap. There is one thing I am not clear on though. Should interlace then be selected (for grabbing live tv) on the advanced tab for Video source type then as well?

Thanks for you help.

Since broadcast television is interlaced, and you grabbed both fields (480 vertical res), yes you want to choose interlaced for source.

Thank you for all the info. My encodes are much much better.

Thanks
