4 pass vs 2pass VBR in CCE?

[REDi]

is there a big difference in encoding time? how about quality? i'm just curious

From 2-pass to 3-pass in CCE, there's a little more quality, but not much.
Over that, it's just a longer conversion time, but no noticeable quality increase.

Try TMPEG 2.53 in CQ mode. It's just about the same quality as CCE in 2-pass mode. Actually I am getting better result with TMPEG in CQ mode than CCE in 2-pass ( and even 3-pass ) mode.

hey kwag r u using CQ_VBR or just CQ and what about the 4 pass vbr and 5 pass vbr is there an increase of quality in those modes

Hi smokingweed3000:

I am using CQ mode with TMPGenc 2.53Plus.

In 4 pass or 5 pass, I guess you mean in CCE, because TMPEG only has 2-passes.

In CCE there's really no visual quality gain after 3 passes.

A while back ago, there was a large thread about this issue..
The person who started it had done alot of research and showed with some graphpictures that 5pass acctually was the best.
4 & 6 passes was acctually the same and 3 & 7 and 2& 8 was acctually the same. Think he used BitrateViewer to get this info, so, 4-5 passes sounds the best. Couldn't find the thread tho..

ok.. well looks like i'll be sticking to CCE with 4 pass.. takes my machine around 9 hours to do a full DVD rip using dvd2svcd.. which seems about right for my 1gig athlon with 384megs of pc133 sdram.

REDi,

9hours???

Just out of curiosity, R U using any filters?
And, what res. did you use, ie 352x480, 480x480, etc. ??

I have done many 1 hour captures of star trek voyager shows and then
encoded them each to (my old method) SVCD (352x480.cq_vbr1850.2520)
and the whole encoding process took me -3 hours!
Below is basically the process I used way back then.

* Source: captured satallite via ATW card
* vdub (filters: resize/sharpen/deinterlace)
* frameserved to
* tmpg 12x (no filters here)
* burned with Nero
* planed on Apex AD-1500, on 13" TV

All this with an T-Brd 900Mhz w/ PC133 128mb ram

Basically, the above method/process has ben scrubbed, he, he...
I have since, many months ago used a better method. Also now includes
a few slightly altered methods I'm currently beta testing now, and looks
good so far (thanks to kwag's CQ mode) This CQ mode is something I kind
of over looked. When Kwag introduced his template, it got me started
with some encoding ideas

9 hours with VBR 4 pass is ok, read normal and even fast for a 1 gig hz proc!

if you do encode this same movie in CQ mode it will probably be 2 or 3 hours

btw, SVCD is 480x480 NTSC, 480x576 for PAL
it's of no use comparing other resolutions and other encoding methods!
