help with best compression for text dvd - evils of interlace and aliasing
on Mar 4, 2008 at 5:06:00 pm

I'm making a dvd that has lots of flying text in it or lots of movement in it. I'm having HUGE problems with interlacing and aliasing and just weird blurring. I have no idea really what is going on.

These are my questions:

1. Should I be compressing footage with fields or without fields. I noticed without fields will make text alias however not have interlacing lines in the moving objects. If I have the interlaced lines with fields, it looks bad in computer pretty decent in a dvd player.

2. Why is there such a huge difference between playing something in computer vs in a dvd player. Does it has something to do with the ram cache in the dvd player?

3. Will bitrate actually improve the way that this non-field or field is being interpreted. I've tried different setups with very high bitrates and this seems to do very very little in terms of fixing these interlacing lines.

4. In most cases, should you be optimizing for DVD player or for a computer player.

Please help I'm about to go crazy. I can't take this crap anymore....
