scale: 1/2size DVD, no qual loss, Fullaudio, smaller filez

[Wayne T]

I'm looking for the simplest way to accomplish the above ... I have an excellent music DVD I'd like to scale to precisely half size .... and maybe 1/4.

I have a lot of tools - even know how to use some of 'em

None seem to precisely fit the job (PAL DVD BTW)

FFMPEG has muy power, but 'bugs out' on me often for reasons I don't yet understand [i don't really understand IT properly yet, either, admittedly]... dvd2one ignores my filesize settings and re-encodes in mysterious ways and has pretty poor docs .. Forty-two looks *real* interesting but doesn't seem to quite 'fit' what I want to do..
any clues greatly appreciated

(even if just to tell me there's a clue offered here, please...... - so many forums, so little time ...


TIA

Choose the 'DVD lo-bitrate PAL' preset and encode your source VOB.
If you don't have the mpeg-2 quicktime plugin installed, also uncheck the "Decode with quicktime" checkbox in the Options tab. Be sure to select the correct audio track in the Audio tab.

thanks for the response Maj,

I'm still 'not getting' ffmpeg well enough to get much use out of it - I *will* but am not there yet ... [I'd nearly need a specific step-by-step 'how to'....


and maybe I didn't make it clear: I have a music DVD I'd like to scale to precisely half size .... and maybe 1/4. By size I mean pic size .. from [768 * 576] To [384 * 288] or half that again - preferably w/o a 'real' re-encode .. so I have exactly the same quality .. at half size, there oughta be 1/4 the data, at 1/4 size there oughta be 1/4 of *that* and I want to it from a real, complete DVD or image not individual files, you see ?

The idea is to use em as small 'samplers' ...

It's impossible to change image size without re-encoding. Use the process I suggested, manually change the image size, and click on "Calc best" button to adapt the bitrate to the image size, then encode.
