I have a 700 MB .avi file that is 1 hour 42 minutes long. Come burn time, my video burning software says the movie will take 6.4 GB on the DVD (which exceeds the capacity of a "normal" 4.7 GB DVD). I realize that if I compress the file to fit on one DVD that there will be some loss in quality. Is there a rule of thumb as to how much you should compress a file (i.e. when you should compress and when you should split onto two DVD's)? At what compression percentage will the drop in quality become noticeable? 10%? 30%? 50%? When I say compression level, I am not referring to a setting, just how much smaller the compressed file is versus the full size file. In my example above, I would need to compress the 6.4 GB file by roughly 27% to shrink it to 4.7 GB.
Should the occasional need to record on a dual layer DVD arise, how likely is it that my burning software (Ulead Video Studio 11), DVD drive on my computer (Philips DVD+-RW DVD8631 GD30), and DVD player (Oppo) are able to able to handle the dual layer format?
Thank you in advance for any helping hands... :-)
PS: I take it from the 6.4 GB file size that the DVD from which the .avi file came from was dual layer (or double sided)?

Hello, me I don't like 2 go below 80% (meaning 20% compression).If u r using dvd shrink,u could reauthor the data and cut tne beginning sequence( till u get 2 the good stuff) and cut(edit) the ending to reduce the data space requirements. also deselect the audio tracks u do not listen 2 and as well as the subs.Save all the space u can for the video. If u know how 2 use VobBlanker u could split the data into 2 discs with v. little to almost no loss of quality.
what program are you using to do your converting? that 700mg file should be no bigger after converting thain 2.8gb-3.2gb in size, you might try using convertxtodvd.
I use Ulead Video Studio 11 at the moment for everything. I might try DVD Shrink to see how it does, I hear it mentioned a lot. I read in another post that there is an option in DVD Shrink to split a large file over two DVD's which would be great as I haven't figure out how to do this with Ulead.
PS: I burned a different 700MB file yesterday that was 1 hour 20 minutes, and Ulead was saying this would require approximately 4.85 GB. Isn't this the norm? I thought I read somewhere that a regular 4.7 GB DVD could hold just over an hour of a high quality video? I could be mistaken though.
Maybe the amount of video you can fit uncompressed depends on the mode you burn/record in? I saw some references on the internet that you can hold one hour of video on a DVD if you burn/record in "hq" mode while you can hold two hours of video on a DVD if you burn/record in "sd" mode. Maybe this explains the large file sizes on my end?
Could the quality of the original .avi file also be partly responsible for the large file size? Here are some numbers from the file properties:
Audio Bit Rate: 95 kbps
Video Frame Rate: 29 frames/second
Video Data Rate: 114 kbps
Video Sample Size: 16 bit
Video Compression: DivXcodec
