Removing Borders for use on PSP

[Fumanstu]

Can anyone help me. I want to remove the borders from a decrypted vob of a film, leaving the same quality of the film. I will then be using pspvideo9 to encode it to a much lower res. I realise that to remove the borders I will have to reencode the film, but whats the best way to do it. Is it possible to just remove the pixels. Please help this is driving me mad.

gkot perhaps
and theword 'best' isn't a real word here ;)

Thanks for the reply, doesn't that use divx or something like that. I tried using pocketdivx, which removed the borders perfectly, but even at its highest quality setting, there was a substantial loss in quality and I then have to encode it again using avc codec. Is there any easy way to remove the borders with say cce and dvdrebuilder or another gui with minimal or no quality loss.

All this encoding stuff melts my brain

Hi!

One way to accomplish removing the "black bars" would be to:

1) Load the .VOB into VirtualDubMOD (Different than standard VirtualDub)

2) make sure that "Video" is set to "Full Processing Mode"

3) From the "Video" dropdown menu, select "Filters', click on "Add" and select the "Null Transform" filter - and then click on the "Cropping" radiobutton

(Make sure you've set "Video compression" to your desired codec and configuration)

setarip_old thanks for recommending the program. OK so I've done practically everything you said, cropped it perfectly with the null transform filter, with full processing mode selected. then when I clicked save as, I first selected uncrompessed RGB as a codec, which gave a mega huge file. Not sure which other codec to use to get an output file of similar size to the input VOB with the best quality possible. Any recommendations.

try huffyuv then

VirtualDubMod won't output in MPEG-2 format, which would be the only thing similar in size to the input .vob. Your other options are to re-encode with DixV or XviD, for speed purposes you can use a high bitrate single-pass which, at a high enough bitrate to minizmize quality loss, will probably yield a larger file than the input, but not a lot larger.

setarip_old thanks for recommending the program.

My pleasure ;>}

I'd suggest you try the DivX v.3.11 alpha codec ("Fast Motion") - set to 6,000Kbps, 100% Crispness, and Keyframes every 10 seconds...

no one told him DGMPGDec/AviSynth?

look in DVD2AVI / DGIndex's forum + AviSynth's forum

basically with DGMPGDec you create a .d2v file, after this you have to write a simple .avs script like this:

LoadPlugin("[PATH\]DGDecode.dll")
MPEG2Source("[PATH\]project.d2v")
crop(8, 8, -8, -8)

(this example crop 8 pixels in all directions)

you find tons of infos about this in the forums
