I am getting lost , and going nuts =[

[tcmjr]

Okay , i have been reading the forum for the last few days
And see everybody got its own opinion (of couse dumboy)

I have download to campare divx5 , divx3 and xvid and svcd
(i really like how divx3 looked)
But here is my problem , technicaly which one would be the best to backup my Dvd ? You see my problem here , size is not that importat , but backing up 20 dvd files each one with 7gb
now its important =]
I want the highset quality , even if it only saves me 2 gb ...

Thanks ppl

I'm not an expert but I didn't quite understand your problem. If you want to backup 20 DVDs then just rip and encode them one by one:) I personally think the divx 5 and xvid codecs are the best. I use gordian knot with the divx 5 codec and get exellent results using 2 80min cdrs. Just follow the guide exactly and you will get exellent backups. If you want to convert your divx backups later to vcd or svcd you can use Tmpgenc. hope this helps

[tcmjr]

Sure !!! that`s what I wanted to hear =]
But is divx/xvid quality better than svcd ?
i always see posts comparing xvid/divx but no them with svcd =[

[scarface]

Like I said before I'm not an expert but this is my personal opinion.
SVCD are exellent quality if you encode them correctly(use DVD2SVCD). You can also play them in almost every console DVD player. I think that DIVX 5 And XVID have better quality if you use the right bitrate and 2 cds. Try it out yourself and compare. Good luck;)

The only advantage of the SVCD format is that it can be played on many conventional "stand alone" dvd players. On a telivision screen you may have trouble telling the difference between an SVCD and high quality divx encode. However, in my opinion, xvid/divx offer higher quality as opposed to SVCD so if it is only intended for back up I think xvid/divx would be a better option.

Also, xvid/divx encoding is "faster" than svcd encoding.

svcd has better quality than divx,xvid,vcd and others!

svcd has better quality than divx,xvid... Perhaps for you, but, not for me.

I've done side-by-side comparisons on a PC monitor. Quality is subjective, of course, but I recently ran a test with a short film (83 minutes) that was a single DivX 5.02 CD and a 2-CD SVCD set.

Why did I see a big difference in detail and sharpness on the 1-CD DivX? I believe it was due to resolution.

The SVCD was, of course, letterboxed 480x480. The .avi had no letterboxing, and matched the film's 2.35:1 display aspect ratio with a resolution of 640x272.

I have also done many side by side comparisons of divx/svcd---a "high quality" divx/xvid encode on my PC monitor is much better in terms of video quality.

[tcmjr]

I checked the svcd that i have here , and its also 480x480
That means , that every Svcd need to be this resolution ?
And with divx i can rip using 16:9 widescreen ?

[jggimi]

Yes. SVCDs are fixed internal resolution. NTSC = 480x480, PAL =480x576. See www.vcdhelp.com for more information. Players will stretch those to 4:3 aspect ratio. Typically, widescreen SVCDs are letterboxed.

With DivX and .avi video, you are using "square" pixel aspect ratios, and the processes used (such as Gordian Knot) will include resizing to restore the content's aspect ratio. As letterboxing is rarely used, the resizing will typically be back to the film's aspect ratio.

[colordog]

My two cents as well -

I also vote for some form of DivX generally looking better than S-VCD, usually because of resolution.

[jorel]

with divx,of course the quality is very,very good but,
when the image is very (much) clear and rich in details.....
tons of blocks!

try to encode the same film with dvd2svcd and use:
lanczosresize,blockbuster and 5 pass in cce.
divx never get this quality......
or you use strong bitrate in divx to see all clear...
but say goodbye to little size!

with divx get little space,
with svcd you get quality!;)

divx is surprising,
svcd is fantastic! :)

editing:

ps: it's only my oppinion,
i do tons of tests,thanks!;)

[tcmjr]

Okay
Stating make a backup copy os Star Wars Episode 1
using svcd , xvid , divx

All of them using Doom9 tutorial !!

If anyone have any tipo before I start , another good tutorial , etc...
When i am done , i will post the pictures here

Well, of course. :p

size
is the word.

- SVCD uses the .mpg-container, not .avi - thus it can store 800 MB on a CD. Use XCD and .ogg to reach the same effect with XviD or DivX.
- An SVCD typically uses the aforementioned 480x resolution and has 1600 Megs in filesize (for 2 CDs). Just for the heck of it try and encode with XviD or DivX at the same settings and resize the 480x picture to letterbox during playback (with BSPlayer or ffdshow for example).

There's no such thing as a technical advantage of SVCD (MPEG2) over XviD (MPEG4), rather vice versa. The only thing that lets MPEG2 catch up here is that it uses more bits per pixel. Also CCE certainly is superior to DivX's two-pass implementation. But I believe XviD's can compete.
