Longer Films

[wayc00lio]

Hi all, I'm pretty new to the forum. Quick question. I'm currently using vDub to join AVI clips, generally with an DivX Mpeg layer 4 low motion compression, then TMPGEnc to convert to authoring flies. When TMPGEnc comes across a huge film, it won't make the files I need for authoring cos the file size is too large (or at least cos it can't fit more than x No mins of film). Is there anyway to make a long film fit onto one DVD without having to make 2 DVDs after splitting the AVI???

Bitrate. Bitrate x length determines how much space is required. The longer the video, the smaller the bitrate in order to fit in the same amount of space. Use a bitrate calculator (look it up in the tools section) to work out what bitrate to encode at to fit on a single disk. This site has an online calculator, vcalc is also handy.

Generally, 2 hours on a single layer disk is about the limit with any quality. After than things start to drop off. Given you have compressed source, 3 hours is probably OK. Longer than that and you should consider half-D1 resolution.

Well I got it working OK. I found that if I ripped the sound off the clips in vDub then put that into TMPGEnc as a seperate audio file instead of using the sound from the origional avi, TMPGEnc then automatically adjusts the bitrate to fit the whole film on one DVD. Hooray!!!!

I just hope it syncs OK now LOL
