    I have a lot of avi files that average 700 MB that I want on DVD. Some will fit on a DVD5, but others are just a few hundred MB too big after encoding(mostly because of length). I use Nero Vision to encode and burn. Some I can edit the ending credits to make fit, others I can't edit enough. I was wondering if anyone knows of a program I can use to compress or compress and edit the avi's to fit on a DVD.

    If the avi's are only 700MB's then they would fit fine, even a CD would do. Your problem is that you are re-encoding. You need to use a lower bitrate. Size = Length * Bitrate, where length is the length of the original avi and bitrate is your new bitrate. The size of the original avi doesn't come into it 700MB, 9GB's, it doesn't matter.

    I may be reading wrong, but I don't understand what you mean. When an avi is encoded to DVD its size increases massivly. Like I said, some 700 MB files fit, but others are way to long to edit to make fit. I know if I burn them they will fit on even a CD-R, but I'm burning them as DVD. I just need somthing to compress the file to make it fit.

    On average a 700 MB file will be 4.7-4.9 GB after I add it to Nero Vision. Then, I will cut out the end credits and it will fit.

    Yes the size increases, this is as I said due to the new bitrate being higher than the old bitrate. As I also said, the fact that they were originally 700MB's means nothing. Only the length matters and the new bitrate. Nero should have some kind of option for changing the bitrate or as you have found by cutting the end off, reducing the length also reduces the size since size = bitrate * length.

    Ok, after cutting the maximum bitrate I can have is 4330 kbit/s. I am not familar with bitrate, so will that drastically effect the quality or viewing experience?

    Bitrate directly effects quality, the higher the bitrate (until the encoder reaches saturation) the higher the quality. Doesn't mean that you can't reduce the bitrate without noticable loss in quality. Reduce it enough and it will definatly become noticable. Also depends on the encoder. You would for instance be able to get away with a much lower bitrate if you were using say CCE as an encoder.

    Well, I'm using Nero to encode. The highest bitrate I could achieve was as stated above to allow to fit. That is including cutting the end. It's a long movie so I guess I can try it. I'll put it on a DVD-RW just incase it is VHS quality. :D

    Thanks for the help!
