Resize and bitrate

[lpinho]

Hi There,

After seeing several forums about the subject, and reading a lot of documentation, I manage to do almost everything I wanted:

Rip a DVD and encoding it with CCE 2.66 standalone version to make a xVCD.

To Rip a DVD I used DVD Decrypter
DVD2AVI to create a .d2v file
Vob2Audio to create a .wav file
Vob2Sub to extract the subtitles

Then I choose AviSynth to frameserve the movie w/ subtitles to CCE encoder.

After learning how to "play" around with avisynth, I still have some issues to resolve:

-DVD2AVI doesn't respect the aspect ratio, so I used a resize function with avisynth (LanczosResize(720,488)), the problem is that when I see the generated file, the quality isn't has good has the quality of the movie generated with FlaskMPEG and CCE plugin to encode...

I don't change anything else about the movie!

What is the best way to respect the aspect ratio of the movie?
Is this the best resize function that exists?


xVCD format that I use:

video: MPEG-1 bitrate: 1860 Kbps (I read in Resize Help in AviSynth (http://www.avisynth.org/index.php?page=Resize) that this resize (LanczosResize) function is good but with high bitrates, what is considered a high bitrate?)
audio: MPEG-1 Layer 2: Stereo - 128 Kbps


Thank You

Do you have some screenshots for us, to support that? What did you do with the avs file, did you encode it with CCE ? What is the source, ntsc or pal?

It's a bit personal, but I would use BicubicResize(720,488) here.

Screenshots, no, not really (sorry about my ignorance, but what program do you use to take a screenshot, isn't the movie shown as a overlay, printScreen doesn't capture it does it?)

With CCE 2.66 it's possible to use .avs files as the input file.
After adding the avs file to CCE I set the parameters of CCE according to the format that I want, and click encode...

The source is PAL - 25 fps - 720x576 16:9

1800kbit at that high resolution is quite not enough. and CCE is reported to be not perfect in mpeg1.

Did you try mpeg2?

The screenshots Wilbert is talking about should come from the final movie. Open the mpg in DVD2AVI and press "b" - a screenshot is placed in the DVD2AVI-directory.

My DVD-Player doesn't support SVCD, so I cannot encode the movie in MPEG-2, I can only read VCD,xVCD and DVD movies (xVCD is a VCD with a different bitrate and resolution). So I must encode in MPEG-1, I know that MPEG-2 is better but unfortunaly my DVD Player doesn't support any home made movies that uses MPEG-2 encoding (at least I still haven't found one)...

Sorry to disagree with you, but CCE is one of the best MPEG-1 encoders, I already tried TMPGEnc, M1, bbMPEG and several others, and none came close to the quality of CCE.


I know where the screenshots should come.

If I use DVD2AVI I can open a mpeg-1 file? Ok, I'll try it..

I'll then post screenshots of the movie, to see if you agree with me...

Thank you

For what I also heard actually tmpegencoder is better for mpeg1 encoding, btw have you checked what are your player compatibilities (strange have I wrote it well?) at www.vcdhelp.com? Go there and check what is reported for your dvd player to play. Mpeg 2 encoding is much better.
But if you have to do mpeg 1 encodings check this thread. I think it's worth it.

Ok, two against one :D

I will try all your advices, and then post my conclusions


Thanks for all the help

sorry, DVD2AVI does not open mpg1.
Use VirtualDub instead and ctrl-1 to copy the source window to clipboard.
