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 |
