Converting from DV to SVCD

[tzachk]

Hi,
I tried for the first time to convert my DV films to SVCD. My camera is PAL and the MPEG I created was PAL.
I captured from the DV camera (SONY DCR-PC110E) with full DV quality (60min ~ 14GB).
I then used tmpgenc to compress it to SVCD/MPEG-2 (60min ~ 670MB with 1300KB/sec).
The result was a jittering MPEG2 file.
Only after I activated tmpgenc deinterlace filter (with even field selected) the file was O.K.
My question is why do I need to perform this action (deinterlace). The film coming from the DV is interlaced (bottom field first), the output MPEG2 file is also interlaced, so why isn't it working right?

Your answers will be appriciated.

Tzach.

Unless you intend viewing the SVCD on your PC monitor there should be no need to de-interlace.

Presuming you chose the PAL template, did you have the Video source type set to interlace? If so, have you tried altering the field order?

Hi,

I have found the answer to my own question. A good explenation of why deinterlace is needed can be found at http://www.100fps.com/ .

it's a nice way of telling how it works...and it does work that way.

Though if you are whatching on a normal television, from a standalone dvd player, you shouldn't have the problem, course it's an interlaced display. If on TV you also have the problem...you prob. have the 2 fields mixed up.

Deinterlacing is nice for computer monitors. Best is vieuwing with commercial dvd playback software who do a realtime bob deinterlace. This way the original file won't get degraded in quality by the deinterlacing.

Good luck.
