I'll make an XVCD template for you...

[puertorican138]

I'll make an XVCD template for you. All you have to do is tell me how many minutes and seconds the movie is, what DVD Player you have, and if the CD is 74,80,90, or 99 minutes.


I like helping others out, that's why I'm doing this :P.

Ahh, I'm game.... I don't have anything specific in mind but how about 60 minutes, Apex AD-1100W, 80 minute CD-R's.....

[puertorican138]

fmctm1sw:

Average Bitrate: 1590
Maximum Bitrate: 2555 (Lower if you want to be safe)
Minumum Bitrate: 1180

Audio Bitrate: 192


The filezise will probably be close to 793 MB's if that's not too bad.


Hope that helps :P!!!

[puertorican138]

Anybody else??? Be sure to tell me the exact time (minutes and seconds).

[biggantdogg]

99min cd-r
max 2500kbps bitrate
good sound
2-disc movie about 110min

[puertorican138]

biggantdogg, you want to know the bitrate to fit a 110 minute movie on 1 or 2 99 minute CD-R's...


For 1 99 minute CD-R:

Average Bitrate: 983
Maximum Bitrate: 2500
Minimum Bitrate: 1148
Audio Bitrate: 224

For 2 99 minute CD-R's:

Average Bitrate: 2192
Maximum Bitrate: 2500
Minumum Bitrate: 1148
Audio Bitrate: 224


Hope that helps and makes your files high-quality :P . Your file-size will probably be around 986 MB/s if that's OK with you.


Your files will be VERY high-quality hopefully!!!

[puertorican138]

It's fun helping people out and telling them bitrates so they can get the highest possible quality on a CD-R :P!!!

[toby tyke]

ok, heres another 1,
"TRAFFIC" dvd/rip 02:21:05
on 2 80min cdrs, please.

regards,
tyke.

[puertorican138]

toby tyke:


Average Bitrate: 1288
Maximum Bitrate: 2522 (Lower if necessary)
Minimum Bitrate: 1148
Audio Bitrate: 224


The file-size should be around 792 MB's of high-quality.

Hope that helps :P!!!

For vcds and svcds you should never use a min bitrate higher than ~500 or so unless you have specific playback problems on your dvd player with low bitrates. Raising the min bitrate decreases quality, it doesnt increase it. A min setting of 0-300 is good.

For 1 99 minute CD-R:

Average Bitrate: 983
Maximum Bitrate: 2500
Minimum Bitrate: 1148
Audio Bitrate: 224

Your minimum bitrate cannot be higher than your avg, its mathmatically impossible.

[puertorican138]

Thanks adam for helping me realize that was too high of a bitrate. I didn't realise the minimum bitrate was higher that the average . Adam, how can having a high minimum bitrate reduce the quality?


Thanks for helping me out, adam :P.

[vitualis]

Think of how VBR works puertorican.

Basically, at easy to encode scenes, you are REDUCING the bitrate so that at hard to encode scenes you can INCREASE the max. bitrate.

Thus, for VBR to work the best that it can, you should have as wide a bitrate selection as you can.

Thus, for ALL VBR encodings:
The max. bitrate should be the MAX. allowable (that is, for SVCDs within specs, about 2500 kbit/s).

The min. bitrate should be zero. However, as some mpeg encoders will inappropriately set too low a bitrate, it is safer to user 500 kbit/s.

The average will depend on the amount video you want to fit.

Thus, for a X/S/VCD that you want to maintain within the 2x specs.:

MIN = 500 kbit/s
MAX = 2500 kbit/s
AV = your choice.

Regards.

Thanks, vitualis.

Thanks, anybody else?

puertorican138...

well, in my topic, you told me you'd help out if i posted at this topic. so, i might as well try it. i asked for svcd settings, although this seems to be for xvcd templates. i have no experience with xvcd, so i guess i still might as well ask for some settings.

my dvd player is *DV-K302CD*. vcdhelp's DVD Players section doesn't have any information about it. (whether it plays xvcd's or not).

i will be using *2 80-min CD-Rs* since my movie is in 2 parts.

part 1 is *0:50:56.154*.
part 2 is *0:51:06.956*.

even though it's about a 10 second difference, i still want to use the same encoding settings for both parts. thanks.

[puertorican138]

biggantdogg, for 2 80 minute CD-R's:

Average Bitrate: 1170
Maximum Bitrate: 2500
Minumum Bitrate: 300
Audio Bitrate: 224

For 2 99 minute CD-R's:

Average Bitrate: 1512
Maximum Bitrate: 2500
Minumum Bitrate: 300
Audio Bitrate: 224

Thanks for replying to my topic, biggantdogg :P.

[puertorican138]

ejb, Part 1:


Average Bitrate: 1871
Maximum Bitrate: 2500 (Since you don't your your player's Maximum Bitrate)
Minimum Bitrate: 300
Audio Bitrate: 224


Part 2:


Average Bitrate: 1864
Maximum Bitrate: 2500
Minumum Bitrate: 300
Audio Bitrate: 224


You can use these settings for SVCD also, thanks for replying to my topic :P!!!

[Spanishfly]

Doesnt the bitrate calculator do this for you?
What is a template?
I am a lil confused why you need to know avr bitrate, min bitrate, and max bitrate?
How are these calculations made and where do you use these settings?
I only see a bitrate setting in tmpgenc. So, where is min and avr bitrate?
And where do you find 99 minute cdr's?

Thanks,
SpanishFly

[puertorican138]

Search this site and you will find all the answers to your questions.

[Mordant]

Yes, the bitrate calc will do this for you. These are not templates, they are just the bitrates you would get by entering the info into a bitrate calculator.

This is a waste of space.

[banjazzer]

This is a waste of space.

I agree. Recent versions of TMPG, using the Project wizard, will do these calculations for you. All you need to choose are the max and min bitrates. I use a minimum of 300, and have experienced no quality problems so far.

[PlaiBoi]

I use a Min. of 1200 and get great quality. My average is know where below 2000 and my max is 2520.

[banjazzer]

Of course you will get great quality. That is not the point. You just won't get the best use of your bits! Even a pure black screen will be encoded at 1200. If you use 2-pass VBR, you will get the same filesize, but not the best use of your bits. If you use CQ your file will be larger than it need be. As Vitualis has pointed out, the larger the range you specify between min and max the better - provided your player does not complain at the minimum setting.

[adam]

The min bitrate does not effect filesize at all. It does effect quality, however.

PlaiBoi you may be happy with the quality you get with a min of 1200, and the I'm sure the quality isn't bad but I can assure you that the quality would be better if you dropped your min bitrate.

Just think about how VBR works. In order to allocate any bitrate higher than your avg it must first free this bitrate up in low motion scenes. Well with such a high max there will be very little bitrate freed up even in the lowest motion scenes. So this means that you will have fewer peaks above your average. The result is an overall lower quality encode.

You should use a min of around 300-500. Anything higher and you are sacrificing quality with absolutely no other gains.

[banjazzer]

The min bitrate does not effect filesize at all. It does effect quality, however.

Yes, I realised after I posted we were talking only about 2-pass VBR, so I have edited the post accordingly. The min bitrate will affect the size if using CQ. If using 2-pass VBR it will affect the quality, but not the size.

[Spanishfly]

Ok, I have some questions.
I make Xvcd's with bitrates ranging from 2000 - 2500Kbps.
I use CBR.
So, I cant find any info on this min, avr, and max bitrate stuff.

I use smartripper, dvd2avi, and Tmpgenc 2.5 to encode
from dvd and my quality is quite good.
I only see min, avr, and max bitrate within smartripper and I dont think I am able to change these settings?

Where do you change these settings?

For my current XVCD encoding project I have a 1:46 minute DVD I am encoding at 29 frames, 4:3 ntsc, 2500kbps, 352x240, CBR, Highest quality (Slow), interlace. Audio 192. I am going to use 3 80min cdr's to burn this to.

Now, in Smartripper it states:
MinDatarate 471/KB's
MaxDatarate 656/KB's
AverageDatarate 581/KB's

Is the Datarate the bitrate?

I get pretty good quality without altering min, max, and avr bitrates, so do I need to do this? If it improves quality I would like to know how?
In addition, I don't know the difference between CBR and VBR?
I always use CBR. Should I be using VBR? Is VBR better quality?

Thanks for reading and any help is greatly appreciated.

You won't, because you are using CBR. This is very wasteful of bits. If you use 2-pass VBR or CQ you have the option to set min and max bitrates. If you are working from a modified standard VCD template, you will need to unlock it to access the other modes apart from CBR.

[Spanishfly]

so what is better?
CBR or VBR?
