Hi!
I recently made "Good Morning Vietnam" (PAL) that has been identified by DVD2AVI as interlaced source. To explain in details: The DVD was made in interlaced-mode but the source was a cinema-movie(progressive), so there are no true interlaced-artifacts visible. Using DivX you don't have to perform a deinterlacing with that kind of DVDs
By now I read two guides on DVD2SVCD/SVCD-conversion
----
fortunately it's a easy-to-use program -> thanks for that dvd2svcd :)

written by doom9 and robshot. They seem to advice different settings:
Robshot advises: "To make the video parameter exactly the same as the original, click on the Video button. Compare the menu below with the Bit rate Viewer session. As you can see, the parameters are: DVD compliant, Zigzag scanning order. If frame Type (in Bitrate viewer) is interlaced then uncheck the Progressive frames in CCE because while the picture structure is FRAME (it's from FILM transfer), the frame type is interlaced (PAL video, remember?). Otherwise, set it to Progressive. Upper field first = Field top first. I changed the Quant scale to Linear to get better quality. DCT precision is set to auto."
doom9 writes: "The default for the anti-noise filter seems good to me. Also leave the other options checked. (Progressive=ON, ZigZag=ON, Linear Quantizer Scale=ON)"
CCE manual states: "However, the non-linear quantization scale is recommended unless there is a special reason."
- Does it really matter that much considering quality if I encode the above DVD in progressive-mode -> looking forward to the progressive future :)?
- What errors (in the worst case) can be seen on TV during playback of a SVCD made this way?
- What quantizer-scale is best for SVCD?
Thanks!
