how to determine the bitrate of an existing divx clip/movie

[concretedonkey]

i know there are bitrate calculators to determine the filesize that a divx encode will produce, but i want to know the video bitrate of an existing divx file. how is this possible? is there anything like a bitrate calculator that will perform this task? i know i can rigth click on the divx .avi file, and select details, but this does not give the true bitrate. any help would be appreciated.

Open the file in VirtualDub. Under 'File' click 'File Information'

In this case, work backward. You know the filesize, play length and audio bitrate of the movie file. Input those values into a calculator and it will yield the average bitrate of the video stream.

thanks enchanter. i did think of that but i kind of wanted a way to find the exact bitrate. the bitrate calc i have only allows you to input minutes and not seconds. it also only lets you input, say, 34 MB , and not something like 34.6 MB so for smaller files this can sometimes throw the bitrate off a bit. i know there are several bitrate calcs out there. is there one that is more advanced than the one i have? it would be nice to know what bitrate calc i need without having to download and test several. although, most of the files i have tested, that i know the bitrates of, have been pretty close. thanks for your advice. also, in vdub selecting file info will not give you the bitrate of the divx clip, atleast i dont think it will. i have tried it before and couldnt find it.

There should be a lot of them around. I myself am still using an old calculator from the time when DivX 4 just came out, but it allows me to input the minute as well as the second. It does not allow decimal values of the filesize, but I suppose this will introduce only a slight deviation from the exact average bitrate, which is perfectly normal.
