Comet’s right – it is quite large considering it’s length…
comet’s wrong – it’s 720×480
comet’s right – it IS about compression, not the capture SW
two from three… not bad I suppose 8)
the movie is compressed using DivX, at a data rate of 84Kbbs at 29 frames per second (though this framerate is not neccisarily indicitive of the framerate that the film was animated at)
the audio is compressed using the Microsoft ADPCM at a bit rate of 354Kbps…. 😮
THIS is why the file is so big… a massive datarate (compartively) using a audio codec that does not offer a particularly good compression ratio.
I only ever use MS ADPCM for my “archive” copy – the file I make my “distribution” copy from – and the file I keep safely tucked away – it’s BIG because I compress it very little, to preserve the quality as much as possible, without ending up with an unuseable multi Gig file.April 20, 2003 at 10:52 pm #1225

I used the shareware Dodcap for much of the film, but I am also working on my own capture software. SMA would not work with my analog capture card.
The video was captured at 720×480 using my JVC analog video camera. That’s the size that my analog capture card does. I now have an Intel CS330 that I will be using. The camcorder is difficult to place due to its size.
It was animated at 15 fps, converted to 29 in Premiere bacause I also dump to tape and/or dvd. Compressed with Divx because I like the quality it gives with good compression.
I did not know that the ADPCM had a poor compression ratio. What audio compressor would you suggest? Sound is not really my thing.
BTW, my original file with no video or audio compression is 1,394,325 KB! Having seen some ridiculously large short films, I didn’t think 16 meg was so bad. I will experiment with different compressors to see what sizes I can get in the future.April 21, 2003 at 12:37 am #1233April 21, 2003 at 12:50 am #1234
