Incorporating a GPL transcoder to DVD2SVCD

[m1482]

In the "ONE click DVD backup solutions forum", there is a thread about a new transcoder to reduce the size of VOB files that is very fast and gives excellent results. I wonder if DVD2SVCD's author is planning to incorporate this type of transcorder when using DVD2SVCD for DVD9 to DVD5 conversion. It is faster than CCE ( just 11 min. to transcode a 195 min. movie) and results are comparable. I made some tests using a GUI develop by NIC, and mutiplexing new M2V file to original VOBs using Ifoedit, and results are amazing!!! It is even better than DVD2One or DVDShrink. It only need a comand line, for example:

"requant 2.0 input.m2v output.m2v" .

Resultant file is a compress M2V file that can be multiplexed with audio and subs to create VOB files...

thanx for the link - i dont get out of dvd2svcd and mpeg4 forums much ;)

interesting thread... still in the early stages tho eh?

wow.. the quality is excellent. and fast!!! i did 70% and 50% encodes (basically bitrates more for dvd2dvdr use)... the 70 was equal to the source.. the 50 was excellent but you could tell it was a reencode.. still nice.. however at svcd bitrate (35%), the blocking and ringing was a bit too much .. now since it was 720x480 it was alot more uncompressible than 480x480 would be. i wonder if a resize could be used and borders added to make it svcd friendly.

@w00kiee:i wonder if a resize could be used and borders added to make it svcd friendly... I don't think so...

It may be usefull to incorporate this transcoder to DVD2SVCD for DVD9 to DVD5 conversion. As you see the quality is excellent and is very fast...

@DVD2SVCD:

No news about this matter !!!

IMHO, transcoding is out of the scope of dvd2svcd program. It is focused to re-coding video and also audio, and this method allows to choose between different input and output formats (AVI2SVCD, DVD2VCD..)

As you probably knows, requant is being improved and probably we will have a tool in a few time able to transcode VOBs using its algorithm. IMHO (again) this is "the natural way" for transcoding tools.

Anyway, it seems not so difficult to write a plugin for dvd2svcd which uses it using Autoit, it's enough to stop dvd2svcd and CCE when CCE starts, launch requant and recover dvd2svcd from muxing. If you are really interested in this method, try to write it, it's easy.
