Current build (1.5.7, stable): [October 20, 2003]
[bugs fixed]

  • Quick preview didn’t work if the current position was
    past the number of source frames, even if the timeline
    was longer than that.
  • Added FPU guards that were missing in a couple of
    critical places (AVIFile open, codec negotation).
  • The timeline wasn’t properly extended if segments were
    auto-attached by filename after edits had been made.
  • Configuration scripts saved when no file is open
    no longer alter the edit list when loaded.
  • Jobs launched from the command line used the normal
    error modes rather than those set as default by the

[regressions fixed]

  • Filter preview buttons weren’t updating the frame.
  • Save Image Sequence command would randomly produce
    an unrequested job instead of initiating the render
  • MP3 audio streams were getting written with
    dwLength=0 if correction was enabled.
  • MPEG decoder occasionally decoded garbage into the
    video frame, resulting in sporadic block errors
    during processing.
  • A race condition in the fast write code occasionally
    resulted in spurious write errors.
  • Append AVI function was incrementing the filename
    extension instead of the name component.
  • Avisynth scripts smaller than 60 bytes weren’t being
    autodetected properly.
