Better to use non-upconverted files for authoring/burning to DVD?

[cognus]

Can one of you pls tell me if my thinking is clear here: to burn a movie file to DVD [standard DVD format] using a good tool like DVD Flick or other, its best to not use files that have been upconverted through one means or another.
Correct?

thank u. great forum!

I don't understand the question. What do you mean by

files that have been upconverted through one means or another

What is your source ?

well, i think that is part of the issue; you don't always know your source unless you go to walmart and buy a dvd and rip it.
a movie file that is formatted to play as, for instance, hi def TV @1080p has been upconverted from something, maybe several generations, then you're going to burn it to standard DVD, by the time you're done you've resampled and rearranged pixels several times, with different applications. I don't see how you could get a good quality image that way.
seems the best policy always is to get back to the original source and hope its a good one. isn't that true?

I guess it goes without saying; "garbage-in; garbage-out"... unless one is skilled to hand-edit every frame, no package can "fix" a bunch of noise that has made its way into your copy.

From reading all the similar posts you are scatter bombing around the forums at the moment, it appears you have downloaded some very poor quality files and want to know why they are crap, and if you can fix them.

The short answer is that they have been poorly encoded, probably at bitrates that are far too low, so people like you will download them. There is nothing you can do to fix it. If you want quality, buy the originals.

Most files that are 1080p or 720p have not been upscaled. They have been taken from Bluray discs or HD broadcasts, which in turn came form much higher resolution film scans or 1080p video masters. If anything, they have been downscaled. Many of the files that have BD/Bluray/HD in the title are not. They may have come from a BD/Bluray source, but they have been crushed down in resolution and bitrate to make small files, and any quality they had was crushed out of them during the process.

If you download crap, all you have is crap.

Do not mistake ignorance for malice.
