I am a total newbie to DVD creation.
I have a bunch of files taking up space on my hard drive (.avi & mpeg) that I want to burn to DVD, so I can watch them on TV.
My questions relate to picture quality.
Ok for eg.
One 500 MB file is 352 x 240 @ 23.83fps (and itâ€™s 72 mins long) 1150kbps
Another is the same quality, but itâ€™s 50 mins long.
My question relates to quality (bitrate settings) â€“ If I wanted to burn both to the same DVD, would the best quality still be really bad because of the space limitations of the DVD (vs. if I burned them to separate DVDs?)
-Or is a case of the quality of the original files (pretty average in this example).
I guess my question relates to decoding a lossy format. (for eg, if I took a 128 kbps .mp3 and made it 256 kbps, itâ€™s size would go up and I could not fit as many on one disk, BUT the quality would only ever be 128 kbps!!!)
-Is this the same with my .avi example above?
If so, what is the maximum (best quality) bitrate I would need to make each file to achieve the best quality possible, given it isnâ€™t great to start with.
-I mean, if I made it 720 x 576 @ 9000 kbps (which would take up tons of DVD space), would that look any better than 352 x 576 @ 4000 kbps, given the original fileâ€™s specs (352 x 240 @ 23.83fps @ 1150kbps)
I guess what Iâ€™m asking is what is the maximum quality I can make â€“ is it identical to the original fileâ€™s specs (i.e., 352 x 240 @ 23.83fps, 1150kbps), or can I make it look better by giving it a higher bitrate, but thereby taking up more disk space?
-Is the answer the same for other compression techniques? (e.g., A would Divx at the same quality specs be able to be put to DVD with higher settings, and â€˜look betterâ€™, because Divx is better, or is it that the maximum quality I can ever make a compressed file always identical to the original fileâ€™s specs? And, if so, what if I make a 352 x 576, a 720 x 576? Is that a bad idea / is it better to leave it as it is? How will it look on a tv at 352 x 576, vs. in 720 x 576, given it was originally 352 x 576?)
Thanks for your help / suggestions!
(Told you I was a newbie!)
