Change Resolution (AVI) - Vdub or FFMPEG

[Delta2]

Hi

What the fastest way to change a resolution of a AVI file ?

I have a 608x336 movie file and I want to change to 624x352

I tried to make a AVISynt Script adding borders ( 8,8,8,8 ) and then recompress with VDUB, it works but is damn slow..and I have many AVI files to convert

I'm trying FFMPEG using this syntax :

ffmpeg -i "Lost.S02E01..avi" -f avi -vcodec mpeg4 -padtop 8 -padbottom 8 -padleft 8 -padright 8 -acodec copy output.avi

Can't I do a -vcodec copy ? because it is fastest and I don't need to recompress, I only want to pad the source with borders

Is the a better solution (fast) ?

thanks

Yes, you do have to recompress - changing resolution isn't possible otherwise. And encoding takes time.

why do you want to change the resolution?

[Delta2]

because I want to encode complete series episodes (TV - LOST) to a DVD, and each one has different resolution

There is no way to join, and I don't want to encode each separately

[mats.hogberg]

Silly mistake, capturing them in different resolutions...

You want to encode them to DVD ? Not just burn the avi files for play back on a certified player ?

The you will have to re-encode them anyway, and putting them all together or encoding them seperately isn't going to make any difference to you timewise.

What are you going to encode with ? Most will support batch encoding, and if you are using a commandline encoder, then just put it all in a single script and batch it. Total time will be the same, output will be the same, and you wont have to drop the extra generation of quality by needless re-encoding.

does VSO ConvertXtoDVD convert 8 episodes of LOST with different resolutions ?

Yes, but you won't get 8 episodes of lost on one disc without it looking like crap, no matter which encoder you use.
