What Happened to the Bitrate Calculator!!!???

[888888]

I used to be able to calulate xVCDs with the Bitrate Calculator found here:

Not any more! What gives!!!?

lol want it as zipped html page for offline wieving?

it is being updated to version 2004

svcd=xvcd=xsvcd, same bitrate calculation.

Question about the bitrate calculator. Say it tells me to use a bitrate of 6301 - If i want to use VBR, what should the settings be for max, avg and miniumum ?

mike

8800 max
6301 avg
300 min

would be a good generalized spread

[sdsumike619]

Funny that you posted 8800 as the max,,, I just read somewhere else on this forum that the bitrate calculator outputs the MAX rate,, so now I'm lost again,, if it outputs the max, how can I put 8800 as the max?

it outputs the average

[sdsumike619]

Oh, then I guess what I read was wrong then,,, thanks!

The average bitrate is what controls the final size of your output file. The minimum and maximum rates are just the range that the bitrate must stay within.

[sdsumike619]

Hmm ok,, so wouldn't that mean that the max could not be above that rate? if it's a range, then the max would have to be 6301 right? if it goes over 6301, wouldn't that make the file too big? I got confused when you talked about the range,,, so should I do what BJ_M suggested and use 8800 as the max , 6301 as the avg and 300 as the min?

[BJ_M]

do what i suggested ... it iS correct

I'm trying to help you understand but I guess I'm only confusing the situation.

I'll try to make it as easy to understand as possible.Regarding bitrates and VBR encoding:

The average bitrate is the only figure that matters when talking about the size of the file. The min and max do not affect the file size only the final look of the video. The encoder will vary the bitrate between the min and max values as necessary throughout the video as it sees fit. High action scenes get a higher rate and static scenes will get a lower rate. The average will always be maintained so that the proper size file is created. The average is simply the total number of bits divided by the running time of the clip.

Analogy: You drive 100 miles in 2 hours so your average rate is 50 mph. 1 hour you drive 30 mph and the other hour you drive 70 mph, you still average 50 mph for the trip.

thank you, I understand it now =)

So, I'd like to understand why my video files always ends with a smaller size.
I've been producing some SVCD with 45:00 min long.
In TMPGEnc, in VBR mode, I set as the average kbps the number which the calculator returned me.
The files in general have been about 700 MB. 100 MB less the CD size.
Does anyone knows a way to calculate it with better accuracy ??

thx
