Video Bit Rate is 350mb for AVI, but larger for a DVD?

[xoanon]

Greetings, I have some AVI files that have Bit Rates in the 1000-1500 Kbps that are HUGE files (350MB). In working with Wondershare Video Converter Ultimate, I noticed that if I lower the Bit Rate to 900 Kbps the file size almost halves. I have many files that need to be converted and want to back them up on DVD+R but can someone tell me what "quality" 900Kbps equates to and will dropping the bit rate this low significantly affect the viewing quality? Any input or help with this would be greatly appreciated. Thanks very much!

Which video format (codec) they are in (both original and the converted)? Without that info, no one can answer your question.

Unless those are really short videos, 350 Mb for AVI is a tiny file meaning, since even a DV-AVI uses about 216 Mb/minute, or about 13GB per 60 minutes, with a 10 bit uncompressed AVI topping out at about 1.620 Gb/minute or about 94 Gb per 60 minutes(those are just for NTSC Standard Definition video), meaning that the video is probably heavily compressed already. But it would be helpful if you knew what codec the files are in.

Most online downloaders use the term "AVI" when they really mean XviD, DivX or even MP4 (x264/H.264) files.
For one of those, 350MB is average, and looks decent because of the HDTV ("rip") source.
To convert these to DVD, it needs 10x-20x the file size to look good. (3500k-7000k)

Or just watch them on a media player ... WDTV, Samsung Blu-ray player, etc.
