    This topic is mainly for Creel but anyone can post.

    As I was watching Black Night, Creel’s movie. I noticed how large and clear the file was. And it was only 19 Megabytes. Creel, what capture program do you use?

    Thanks.

    Well…it was only three minutes if I’m not mistaken. 16 mb is quite big for that, even at 640×480.

    And your main question is with his compression, not his capture software.

    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…. :o
    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.

    It’s 720×480? Odd. I thought he would change it to square pixels. That’s probably why you said it looked squished, Bluntman, the movie was most likely using rectangular (.9) pixels instead of square pixels. That can look a little screwed up on a comp.

    Cometgreen, the pixel man

    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.

    Thank you everyone. I will use your advice to try and upgrade my films. :)

    For what it’s worth, I archived all the raw files for Out Of Time (dialog, video, foleys, etc) to ten CDs.

    That’s a lot of disk space freed up.

    To archive Black Knight, I zipped the uncompressed files and then saved to DVD.

    Personally, I use MP4…. It comes with DIVx.
