  • DS Muxer:
  • The muxer is currently limited to muxing streams no more than
  • approximately 9.942 hours in length. If you attempt to mux a stream
  • longer than this the resulting MP4 will be corrupt.
  • 3ivx Installer:
  • Requires computer administrator to install.
  • Unknown Bugs:
  • DS Muxer:
  • When using an Apple File Share, you probably can't mux streams over 2GB in size
  • Missing Features:
  • Core:
  • Interlaced decoding is not implemented for S-frames (GMC)
  • DS Media Muxer:
  • Fragmented Muxing is not ISO compliant and has been disabled.
  • Mac QT Media Importer:
  • Media Importer is not release quality. You can install it via a Custom Install on Mac OS X
  • Media Importer is PowerPC only.
  • Non Issues:
  • DS Muxer:
  • The splitter can not be connected to the output of the muxer.
  • Permanent Issues:
  • Core:
  • XviD streams prior to build0000 (ie up to and including 0.9 stable
  • series) with non-multiples of 16 are not MPEG-4 compliant and exhibit
  • occasional glitches. There is no work-around.
  • NVops (not coded PVops) can be used to more efficiently represent dropped frames or frames which are identical to the previous frame. NVops are not correctly handled by the QuickTime MPEG-4 Stream hinter and will cause a -5402 error when attempting to hint a file which contains NVops. The solution is to not use NVop coding. The 3ivx DirectShow Media Muxer can be used to remove NVops from an already coded bitstream. (This is currently still an issue with QT6.5)
  • QT Codec:
  • QuickTime 7's native datarate setting is now in kilobits/sec. There are
  • 1000 bits in a kilobit, and 1024 bytes in a kilobyte, according to the
  • QuickTime Player. Due to a work-around for an error in QT7's kilobit->byte
  • conversion, third party applications which do not use the QT7 codec
  • selection dialog to obtain a datarate from the user (in kilobits/sec) may
  • end up undershooting by a factor 1.024 (roughly 2.5%). In order to correct
  • for this multiply the datarate you enter into affected applications by
  • 1.024. This is only an issue when using QT7.
  • Win QT Codec:
  • When one movie has two or more video tracks, each encoded with 3ivx
  • there may be problems playing the video when DirectDraw Acceleration
  • is enabled in the QuickTime settings control panel. Work-arounds,
  • disable DirectDraw acceleration, or DirectDraw.
  • Adobe Premiere Elements 3.0.2 crashes when loading the 3ivx QT Codec. There is a work-around available, simply rename the CompilerQuicktime.prm' file to 'zCompilerQuicktime.prm'. The file is located at 'C:\Program Files\Adobe\Adobe Premiere Elements 3.0\Plug-ins\en_US\"
  • DS Splitter:
  • Windows Media Player 11 does not allow seeking when opening mov or mp4 files from within a library. The Solution is to open these files
  • directly.
  • DS Video Decoder:
  • Windows Media Player 11 does not post process and ignores
  • "Auto-Select for Video Filter Level" in the configuration pane
