• Museum of Multimedia Software, Part 1

  14 août 2010, par Multimedia Mike — Software Museum

  Many years ago, I found a boneyard of old software, much of it related to the creation and processing of multimedia. I was permitted to liberate anything of my choosing from this cache. This is the same pile where I found this Apple QuickTime format spec as well as this perfect form factor floppy disc box. So I have been sitting on the stuff for awhile.

  I thought I might get the chance to study it a bit more closely one day. But now I’m interested in getting rid of it. Before I do, it’s more or less traditional for me to photograph it and post it on one blog or another. Also, if you know of any software collection groups who would be interested in taking this stuff off my hands, do let me know.

  As usual, click a picture for a much larger image.

  Paracomp FilmMaker
  This is easily the most distinctive piece in this collection and it’s easy to see why— the software is packaged in a film cannister. Still sealed, and I don’t have a good reason to open it now.

  
  
  

  "The Professional Animation/Presentation Program for the Macintosh." No copyright date on the packaging, though the front does mention a 1990 award. System requirements : Mac OS 6.0.5, 5 MB RAM, 32-bit QuickDraw, math coprocessor.

  Strata VideoShop
  Version 4.5 (and not for resale), still shrink-wrapped. "The Digital Video Editor for Creative Professionals."

  
  
  

  System requirements : PowerMac with 5 MB RAM (8 MB recommended), Mac OS 7.5.

  BeatWare e-Picture
  "The Professional’s Choice for Designing Animated Web Graphics." Claims a best of show award for 1999 MacWorld New York Expo.

  
  
  

  System requirements : PowerMac with Mac OS 8, 32MB RAM, 10 MB of HD space and a 256-color adapter.

  BeatWare eZ-Motion
  Another offering from BeatWare. "The fastest and easiest way to create animations and graphics for the Web."

  
  
  

  This one is for either Mac or Windows. 32 MB RAM and 25 MB HD space required. Works with Mac OS 8.5, 8.6, or 9.0, or Windows 98, NT, or 2000.

  1- i have a little movie file of 1 minutes ( movie.mp4)

  2- i have an mp3 file of 10 seconds (voice.mp3)

  I whish to add this mp3 file in the middle of my film (at 30 seconds).
  My question is :
  Is it possible create simply a new video (movie2.mp4) with my mp3 added in the middle of the film (at 30 s) ?
  Or maybe is exist a c# library or c++ to do this ?

  Thanks
