Jumpy playback...

[FilthyGiant]

I'm new at this...from a 700 meg AVI I encoded with TMPG:

+ Used audio from a pulled wav via VirtualDub

+ Interlace, Bottom field first, 4:3 525 line (NTSC, 704 x 480), Film Movie

+ 2-pass VBR (4840avg, 8000max, 0min)

+ Motion estimate search (fast)

+ Force picture type setting

Burned at 1x with Ulead Movie Factory 2 (Sony DRU500AX)

The problem: the DVD plays fine in my DVD player, but every now and then there is quirky, jumpy frames. The audio is not affected and remains in sync, but the frame jump is a little annoying when going for perfection. With these discs, I could burn up to 2x, and tried with the same results. I figured 1x would be even safer.

Any help would be appreciated...

Oh by the way, the computer specs are not a problem:

Pentium 4 2.2ghz
1 gig of PC2100 ram
2 120 gig hard drives with 8 meg cache

Although true interlaced is B-Field first, some cap cards grab A-Field first. Reverse the fields during your encode to match source. Should solve it.

Agreed

Okay, so I should try interlaced with top field first...What difference will the interlaced and non-interlaced make?

Should I stick with the force picture type setting?

And should my minimun bitrate be at 0, or should I bump it up to like 2000?

thanks

On MPEG2 for DVD, make padded min be 2000k. SVCD or CVD can be whatever, though 2000k minimum will look better.

I never use Force Picture Type Setting (although it may be suggested sometime for VBR rates). Either way, I never do it.

Interlaced or progressive or non-interlaced.
1. Interlaced is two fields (tow pictures) shown at once, but becuse of how tv's work, you don't see it.
2. Progressive. One image after another. Tv's only do interlaced. HDTV will do progressive.
3. Non-interlaced. A) Low resolutions or B) interlaced than has had a field blended or removed. VCD is low resolution. 352x480 is about what a tv can physically show you, so stick to that res for DVD work sourced from non-digital video footage.

Some of this explained in the VHS->DVD guide below.
