Quality differences on older machines?

[Ikasu]

It's always been a habit of mine to rip my dvd movies onto my harddrive so I can refrain from using the DVD's too often. I prefer just ripping the sucker to my hard drive and running it via alcohol or daemon tools but I just realize something...I'm running out of space!...1.4 TB almost gone...lol.

I've been doing video editing and encoding for years but I never though about one thing...Is there a quality difference using an older machine to encode?...Yes I know that it would be slower...as well as the fact that it uses a older SSE instruction set which wouldn't make it the quickest solution..Why am I asking this?.

Well I need space...frankly...and these DVD's are taking up almost all 1.4 TB on this sucker...around 700 Gigs atm..While the other space is occupied my music, games, video editing sources and other jazz. I've been a guru in the past when it came to video encoding but I stopped that learning curve before x264/h264...Getting back into it and just installed megui...Thank god being a veteran in avisynth and DVD2AVI (now reworked as DGIndex ^.^) The learning process is fairly quick and easy...But here's the main question....My computer is almost always in use so I can't encode on this sucker. I'm always editing or doing something non productive (watching movies and playing games ^_^). So I was looking at my two older rigs and I know my p3 933 can't handle it...But my dual AMD MP 1800+ workstation might be able to do so...Would there be a quality loss at all?...I've never thought about quality differences using older hardware since it never crossed my mind...But just wanted to ask before I start encoding these sources.

One more question. If I go for a straight max quality encode..basically try to keep them as perfect to the source as possible..Would I even save up much space?...Been out of the encoding loop for a while so I don't know how well x264/h264 scales in terms of size. I don't mind if it drains the dual amd mp rig to death...the computer doesn't do anything right now..and having it encode 24/7 for me would be a proper use for it since it's just collecting dust.

Sorry for the long post for such short questions...I'm a thorough individual ^_^...

Is there a quality difference using an older machine to encode?

The program is the same, the data is the same. Therefore, the output is the same.

Yep that is my suspicion as well.

Assuming you use the same dvd and use the exact same codec settings bit for bit it should be identical. The only difference would be the encoding time.

You better find a way to store all that stuff off your HD's...

Assuming you are using the same burning software, quality has more to do with media 1st and the burner 2nd. Most name brand burners should give very good quality. I suggest using only Verbatim and TY blank media, they are the only consistently good media IMHO. Also, since you already have them ripped to your HD, IMGburn is excellent burning software.

Ehhh?...I guess I confused a few people. I'm not planning to burn anything. I have my old dual amd mp 1800 PC on a network. I'm planning on transferring the DVD iso's from this computer to my old rig. Then run x264 and h264 encodes of every dvd...then drop the iso's cause they take up too much space. But curious...What would the file sizes look like encoding with the highest quality possible?...of course I'm going to run a 2 pass encode...just curious on how large all this is gonna be...Will the 264/h264 be significantly smaller in file sizes with the same quality?...or will I be losing a lot? Am I dreaming to think I can get away with the near dvd source quality with less file sizes?

Thanks for the replies guys ^_^..really appreciate it.

There may be minor differences if the program you are using can make use of CPU features available only on more recent CPUs. Any such differences should be insignificant unless the code for calculations on the more recent CPUs is notably more precise.

To all intents and purposes, though, you shouldn't detect any differences.

tyvm ^_^...I'm quite anal on quality so it would drive me nuts if I notice any degrading from my dual amd mp rig to my workstation rig.

Thanks for the info guys! ^_^. Going to start transferring soon..

BTW...Does this tutorial cover all the techniques needed to get the highest quality encode possible?

Or should I be reading more before I jump into x264/h264....unfortunately I'm a x/h264 newbie ^^.
