I was encode already several movies with MencodeMe and I can see that:
(Avisynth + TMPGEnc + mpeg1 + 1Pass encoding) better than (Avisynth + MencodeMe + mpeg1 + 2Pass encoding)
Despite that, I still prefer MencodeMe, I forget any thing about file size prediction, and it is quicker than TMPGEnc. But for purists in the matter...
I think that suffer same quality loss, in mpeg1, than ffvfw with libavcodec.

Hi Prodater64,
If you try (AviSynth + MencodeMe + mpeg-2 + ( 1 or 2 Pass encoding)), you'll find out that mencoder's MPEG-2 is better that TMPEG's MPEG-1
So right now, quality wise, mencoder (libavcodec) is the best, even better than TMPEG's MPEG-1, for low bitrates too.

I haven't even gotten MEncoderME to produce a working mpeg-1 with
or without avisynth, 1 or 2 pass, etc. I don't believe it can If we
compare mpeg-1 with MEncoder vs Tmpgenc that couldn't be true
If MEncoder can take mpeg-2 and compress a movie that uses the same
file size as low bitrate mpeg-1, than that is an amazing thing. But no one
has claimed this and even suggested that it can.

I agree I you are comparing, mpeg-1, Tmpgenc is still the
winner I've always gotten better picture quality with mpeg-2,
but file size and stand alone player compatibility are issues.

But I already did
Look:
http://www.kvcd.net/payback.mpeg2.mpg.cut.37.mpg
And yesterday:
http://www.kvcd.net/shell.mpg.cut.18.mpg
Full movie at 704x480 on one CD-R, encoded with MencodeME, MPEG-2, using "DVD" filter combo, muxed and burned as SVCD.

I don't knew this.
Does it mean that I must to use (quality wise) "AviSynth + MencodeMe + mpeg2", even for low bitrates?

Just make a quick test, without any filters.
Try TMPEG MPEG-1 and Mencoder MPEG-2 on low bitrates, targeting same file size.
You'll see mencoder's MPEG-2 is better than TMPEG's MPEG-1.
So when you add filters, either AviSynth or mencoder's internal filters, you'll get even better results.

I don't know how make it.
1 - Run a sample with tmpgenc cq 100 mpeg1.
2 - How can I calculate same file size with mencodeme (maybe with calcumatic, I give it a file size and it give me a bitrate, or in mencodeme I can select file size too?)
3 - Run a sample with mencodeme and compare.

You only have to calculate the average bitrate for mencoder. If you don't know:

Sorry to be a dumb a*s but If i want to put a movie on 1 cdr but use your method what do i have to chage,can i use 528x480.
What do i do
1.Use ma script through makeavis
2.Select dvd filtering combo
3.1 cd KSVCD
4.What bitrate -the average from cq matic
5.Do i need to change max bitrate
I also haven't had the best luck using mpeg1 with mencoder and tmpge has been far better for me so i would like to try this method but don't know where to start.
Thanx

@bigggt
When using a fake avi generated by Avisynth, use only the "no filtering" combo and the MakeAVIIS profile, any other will resize the video and you already done that in the script.

Yes. If you selected some filters in AviSynth, then select "No Filter" as filter combo. Quote:
Yep. Quote:

It's already set to 2,500 by MencoderME Quote:

If your player supports SVCD, you'll be fine when you encode with the KSVCD setting in MencoderME

AFter reading your post all i can do is shake my head at myself I need a good once in a while,i don't know how many times i have read this in the past
Anyway i guess that brings up my next question if using mpeg2 to fit on 1 cd are you getting better results with the dvd filter combo(mencoders filters) or through using the ma script with fake avi

If your movie is an action movie, you'll get better results using the MA script, making a .avs script, and using MakeAVIs.
It it's a low action movie, or a movie that doesn't contain many fast action scenes, then use Mencoder's internal filters, because encoding speed will be FAR faster than using any AviSYnth script combination.

@Kwag,
Wow kwag I didn't know that. I have several movies I'll try
right now. Most KSVCD's work great on my stand-alone-player.
This is getting exciting I 've got to think more outside the box

So if you encode at an Ultra-Low-Bitrate in MPEG-2 with 352x288 VCD resolution... Would you mux the file as VCD or SVCD?

I tried making a test with SKVCD and have a few more questions.
Do i need to use pulldown
2.I loaded the mpv file into avicodec and it says its mpeg1 ,shouldn't it be mpeg2
Thanx

Ok thought i would post my first results
avi filter 1 cd kscvd ,i had a lot of errors in the log something like duplicate frames or something(frogot to copy it) but when i muxed it seems to be pretty good.
Anyway the video is quite good but not as good as tmpge(at least so far)
I am going to try a dvd now and see
BTW i did a 2 pass which took about 5 hours which in tmpge this movie took me 10 hours.

I don't remember having an error like this... does it also say something about DCT coefficient?, I guess no, this is another kind of error.
Remember, if DCT coefficients error, that you can try raising VBV value.
