DVD compliant resolutions
Hi all,
I've been reading thru these forums trying to find an answer but i unfortunatly cannot. The problem is that I am capturing vhs and trying to convert it to dvd. I capture the tapes at 352x480 and then resize down to 352x240, this i have found gives me the best quality when converting to dvd because it retains all of the vhs signal and does not introduce interlacing. Anyways, my problem is that if I encode a dvd with the same resolution (352x240) it will play in a dvd player, but it stutters and pauses every few seconds. Were as if i encoded it with the exact same settings (using tmpgenc), except having the resolution at 720x480 it plays just fine. My question is then,is this normal for a player to do that at that resolution? Or should i try encoding at 352x480 because i have heard in the forums that this is a compatible dvd resolution, my only problem would be getting the aspect ratio from 352x240 to look right at 352x480. I am not trying to make a svcd or anything like that I have a dvd recorder (sony 500a) and I am trying to make compatible dvd discs only I would like to stay at this resolution because it saves space, encodes MUCH faster, and there is no point in increasing the resolution of these vhs tapes. Thanks |

Hey everyone,
I am encoding these using mpeg2 and tmpgenc's default dvd setting except for a few settings like the resolution and bitrate. Im also encoding these using 2pass vbr set with an average at 3200. So the resolution of 352x240 is called sif? Im starting to wonder if it is perhaps a problem with my dvd player, its a proscan ps8680z, has anybody else succesfully encoded dvd mpeg2 at a resolution of 352x240? Thanks again |

Ok, i think i figured out that an mpeg2 dvd of 352x240 is not as compatible as I thought. However 352x480 is (right?), so how do I keep the correct aspect ratio when encoding a 352x480 ntsc mpeg2? Sonic reeldvd tells me that it only supports 4x3 which is what I told tmpgenc to encode it at but apperently that doesn't work. Help please?
Thanks |

There's no problem with the 352x480 resolution as the 352 will be 'streched' on playback. You need however to specify the correct aspect ratio in the VTS*.IFO files, and you can use IFOEDIT to do that. This procedure is explained in the SpruceUp authoring guide at http://www.doom9.org/mpg/spruceup.htm |
