Quicktime is Driving Up to Wall at DVinfo.net

November 3rd, 2002, 02:42 PM

I want to know if anyone have preference over Quicktime streaming video vs Real On video streaming.... I have all my video in Mpeg and it actually stream when poeple are on cable (bitrate of 1200kbits/s...how does that work anyhow?). I m trying out encording quicktime but bitrate works wired. When I set the bitrate the same as my mpeg (1200kbits/s) the QT file ended up being like 20 megabytes bigger in 3 min video...

What's going on here?

Check this (cause I may not know what I'm talking about), but I think real's bit rate is in kiloBITS, whereas quicktime's data rate is in kiloBYTES (and 1200 kilobytes/sec would be a rather hefty file.)

Hi Barry,

Yah, I checked it and I've been doing it by 700 kilobits/ 8bits = 87 kilobytes and stuff. You are correct, QT ask me to input the bitrate by kilobytes instead of kilobits... so I am not sure what I am doing wrong here.

What compression scheme are you using with QT?

I m uisng something call sorencence codec. It's not sorencence 3, but it's regular one... I can't get the exact name because Vegas is cranching out the file... it's wired, because I did a test on the same file of the same length with real media codec, and I ended up with a file that is 3.5 megabyte and it look as good as 7.5 megabyes QT files. I compared with those two with my typical MPEG1, and my MPEG1 looks horrible (5.5 megabyes)

Where are you from? Do you wanna have a look?

Ahh!!!
