KVCD: 150-minute SVCD HQ-resolution on CDR-80 ?
 

When trying to get further optimization (increase video quality, reduce
filesize) I´ve tried to encode the movie in interlaced mode (cause the
TV set displays in interlace mode anyway).

So instead of 25 fps non-interlace (progressive) I selected 50 fps
interlaced. This needs to select MP@HL in MPEG2 mode.

Test encodings of 1min samples issued filesize of about 60% for interlaced
compared to non-interlaced (100%). At 448x448 active SVCD
windowsize (in 480x576) I´ve got ~ 5MB/min @ cq 75 in TMPGenc
bringing a total playing time of about 150min at fullSVCD resolution.

The trick is using field based encoding instead of framebased encoding. My S/A player Panasonic RV32 plays this flawlessly (so far).

I still get some block artefacts in scene changes so I´ll try further optimizations (field order, etc)

Maybe someone will check this too and let us know the results of
his S/A player (some players are known to run into trouble @ field based
encodings)

Obrigado

Is this optimisations for the SKVCD template..?

> Is this optimisations for the SKVCD template..?

well, mhh, yes, no ?

it only applies to SVCD because of MPEG2
(interlacing is not applicable to MPEG1 standard)

but it´s independent by it´s natur from KVCD templates.
Anyway
the K-templates are very useful base, so I used the basic KVCD
strategy of long GOPs and size optimizing matrices.

This way goes beyound and might push KVCD further forward.

I´ll forward a template soon
so anyone could play along.

Obrigado

Cool, I look forward to seeing that template :) .. as SKVCD is the only template my DVD player plays (apart from MPEG1 templates at 352x240/288).

what happened to this Interlaced SVCD?

KVCDx3 is working very well in almost all APEX DVD players
at 544x480 MPEG-2.

But, my sources are 3hours long and I want to fit them in 2-cds.

Interlacing might help.

where r u man?

when will u release ur template?

TIA
