this is how it was done over 130 min svcd on one 80 min cd

[fox26]

hello everyone i post it before that i can put 130 something min svcd quality on one 80 min single cd well this is how i did it.........


First open TMPGEnc click on load used SuperVideoCD (NTSC).mcf now in the same place where you got the super video temple there is a extra dir there load the unlock.mcf


Now load your movie that you want to convert to svcd where the video source is, it will be the same for audio, source output is where you want to save your movie


Ok now let do some setting:

1) Click on setting

2) Click on video if you not there for stream type it most be MPGE-2 video
Don’t try this for VCD movie is not going to look good ok let keep
Going with this so call guide :D

3) Now for size it most be 480/480

4) For aspect ratio it most be 4:3 display

5) Frame rate 29.97 fps

6) rate control mode it most be CQ_VBR click on setting next to CQ_VBR
Set the quality to 20 if your movie is under 160 min now if you got
A movie about 134 min set this to 25 for better quality now remember
That your movie source most be great quality to get good looking svcd
Now click on maximum bitrare set that to 1000 and for minimum bitrate
To 500 and close that window

7) VBV buffer size set that to 48

8) Motion search precision: well this have to with your pc if you have a
Great pc im talking about over 1.5 MHz p4 then set this to highest
Quality is going to take more time to encode but much better quality

9) Now click on advance for video source type set that to non-interlace
For field older set that to bottom field first B now the source aspect
Ratio it most be the same 4:3 display this is good for TV not for pc
Now for video arrange method set that to center (custom size)
456x314 now don’t check any of the boxes

10 ok next click on quantize matrices there only check used flouting point
DCT and do not perform half-per motion search in still scenes


11) Click on audio for stream type set that to MPGE-audio layer 2
For sampling frequency 44100 for channel mode stereo for bit rate
128 that is all for sound


12 now click on system for stream type set that to MPEG-2
Program VBR and we done go back and click on encode


Let me know what you all think of it, sorry if im not good at
Posting guides but I have done my best take care all and god bless

When your bitrate is as limited as this you simply must take the necessary steps to ensure that what little bitrate you have doesnt get wasted.

If possible you have to do an inverse telecine or in the case of a dvd use force film if applicable. This free's up %20 of your bitrate right there.

Also at 480x480 resolution I don't think its possible to get acceptable quality with that little bitrate. A standard vcd would look MUCH better. I think if you are going to sacrifice that much bitrate you need to lower the resolution to 352x480, which will still play on all svcd compatible dvd players because it complies with the cvd standard, or you need to go with 352x240 and mpeg1 and create an xvcd.

well i have make some movies at 480/480 with good quality not dvd quality but hey it play great on my home dvd player

[mickboss]

Don´t get me wrong but I think that it is MUCH MUCH better to use 2 CDs and get GOOD QUALITY video instead of using a single CD with...well... even at VCD resolution...

If you want to make copies/backups of your films wy don´t you at least get something good?

Is this a battle to see who makes the xvcd/xsvcd with more minutes/cd?

Video at 1000 Kbits/s and Audio at 128 Kbits/s.... .... ....

I produce SVCDs PAL 480x576 at:

Video: 2200-2800 Kbits/s
Audio: 160- 224 Kbits/s

with HIGHEST QUALITY, CQ_VBR 100 and I STILL think this isn´t enough quality!

If I wanted to produce video at 1000 Kbits/s I didn´t use DVD / Cable source...I would use VHS or something like that...

BUT: this is only my opinion and my personal choice for my own backups 8)

This doesnt really have anything to do with this thread but mickboss, CQ_VBR at a quality level of 100 is literally the same thing as cbr. Whatever max you set it will just encode in cbr at that level, only it will take much longer to do. You would be much better off just encoding in cbr to speed up your process or to use 2-pass vbr and increase you avg bitrate. With 2-pass vbr you would get better quality in a smaller filesize.

Fox26 - How about contributing that method to this post.....

[sean madison]

nonono, u cant do this people

Quality of 20, 25 whatever, i used to use 34 cuz i thought it was good, but it is VERY bad quality

If anyone is gonna use cq_vbr, please use 58-63

To find your max bitrate possible(i got an estimate formula i made), im me on aim or email me, i'll teach it to ya.

Sorry i cant post it right now, kinda busy

[adam]

Sean you don't calculate your max, it should either be the highest amount that the standard allows, ~2.6mbits, or the highest amount your dvd player allows, should you choose to deviate from the standards.

And the level that you use for CQ encoding depends on how much compression versus quality you want. There are no rules, its a subjective decision. If quality is your concern then you shouldnt be using CQ at all, its only purpose is to speed up the encoding process. 2-pass vbr and intelligently thought out bitrate settings will always yield higher quality then CQ at any quality level.

[sean madison]

yea i know adam but just read this-

I always put my movies onto 1 cd unless they are over 2 hr 10 min ok
So here is an example of a movie under 2hr that is a dvd rip in a d2v file ready to encode.

I use my calc and lets say max cbr bitrate is 1000.
Well, this is what i do now-
I choose 2 pass new type vbr
min-0
ave=1000
max-1441

You may be wondering, why is the max such an odd number?

U got me too, but for the sake of what i have done so far, i have encoded 2 dvds using this method and BOTH of em turn out no more than 15 mb difference!

You can take this advice and try it yourself and if i ever run into a probelm with file size, i'll let everyone know.

Just remember how this works-
min always 0
average is what calc tells u
max is adding 441 to average

[sean madison]

i just encoded another movie and file size is 22 mb smaller than cd size!
It might work for everything now

[adam]

In your particular case the max might not even matter since your average is so low. You could set your max at 9MB per sec and it still probably wouldnt ever get higher than 2MB's at the most. But the fact remains that your methods are still illogical and incorrect.

I don't think you understand how min max and avg bitrate settings work. Your min and max bitrate setting do not affect filesize. The size of the mpg is solely determined by your average bitrate setting. The encoder takes your min and max settings and uses that as an interval to select appropriate bitrates. It allocates bitrate according to where it needs it most but always maintains the average that you set. The larger the interval you have to pick bitrate from the better. The only limitation on your max bitrate should be the svcd standard or your hardware players capabilities.

0/1000/1441 makes absolutely no sense. If the encoder determines that a scene needs 2Mbits's per sec to look good then why limit it to 1441kbits? All it will do is distribute that bitrate to a scene that needs it less. The filesize will be equal in both cases but with a max of 1441kbits the quality of that particular scene, as well as many others, will be significatly lower quality.
