Making non-anamorphic movies anamorphic

#1

Would it be possible to crop a non-anamorphic movie, and turn it into an anamorphic one when doing a back-up using DVD2One. Or is it something I would need an encoder for (I am well aware that D2O only compresses).

TIA

First off, any resizing/cutting needs a complete re-encode; DVD2One only does “re-compressing” and is therefore out.

Second, I see no sense in “force-anamorphing”. You can stretch the picture vertically and have TV stretch again horizontally (if you have a 16:9 TV, otherwise the DVD player would shrink it back vertically)… Which is practically what your TV does automatically when zooming a letterboxed movie to 16:9…
Anyway, stretching the picture around will only decrease quality, so why bother?

Well I was trying to backup Casino last night, which is nearly 3hrs long - and the quality I got was pretty ropey (Which I did expect mind you - being so long a movie). It’s not anamorphic. I’m not an expert on exactly how this all works - so I was hoping/thinking that not encoding extraneous black bars would leave more disc space for the picture. An extreme version of ‘lossy compression’ if you like.

But since it requires a complete re-encode (and not just a case of ‘lets just chuck it away during compression’) and I can’t be bothered to download/learn a new tool, I’ll have to live with it.
Oh well!

dougwright,

Casino is most definately anamorph. The fact that you still see those black bars is that its format is 2,35:1 (“cinemascope”) and not just 1,85:1 which is “bar-less” on 16:9 TVs.
Besides, if correctly mastered (i.e. black bars are really black so there’s zero motion data), those black bars compress to virtually “0”.
Edited to add:
Also, from your description, by making a film anamorph, you replace the highly compressable black bars with picture contents! Back in the SVCD days, you’d go exactly the opposite way to save bitrate: going from anamorph to letterboxed. :slight_smile:

Your only option, besides true elaborate re-encoding, is to split the movie onto two DVDs. Not too expensive with today’s media prices, plus you have no quality compromise and retain all extras/menus.
In that case I recommend DVDToolbox ( http://www.dvdtoolbox.de ) which is really fast and easy to configure.

Well mine isn’t anamorphic (UK). I do know the difference between anamorphic and not - just not all the techie ifo/vob stuff.

I believe you on the problems involved though in backing up the disc! :stuck_out_tongue:
