- ===================================================================
- For product support and the latest release notes, please visit in
- Nokia's Developer Home at http://www.forum.nokia.com/
-
-
- Product Description:
- ====================
- Nokia Multimedia Converter is a tool for converting common
- multimedia files (AVI, WAV, MPEG, MP3 etc.) into standard 3GPP/AMR
- formats for use in mobile phone applications such as MMS
- (Multimedia Messaging).
-
-
- Features:
- =========
- - Converts common multimedia files to 3GPP/AMR format files
- + Video: H.263 (profile 0)
- + Audio: AMR (AMR-NB and AMR-WB)
- - Console and graphical tool options for converting files
- - Playback common multimedia and 3GPP/AMR format files on PC
- (graphical version only)
-
-
- New Features:
- =============
- - Support for 128kbps bit stream H.263 video
- - New improved user interface
- - Improved AMR-WB encoder
-
-
- Enhancements:
- =============
- Several major bugs fixed:
-
- Fixed problems for graphical and console tool:
- First second of the audio is left out in the converted file.
-
- When converting NIM files with graphical or console version
- of MMC, frame rate is dropped to 7,5 although default is 15.
- Changing frame rate conversion parameters doesn't have any
- effect on this.
-
- There is no audio included in converted file if original file
- is of type NIM.
-
- AMR-WB encoder was vastly improved: "empty output file for
- certain wav-files"-bug was fixed.
-
-
- Fixed problems for graphical conversion/viewing tool:
- In some cases the system hangs after a large file is
- converted and new file is selected for editing
-
- MMC GUI sometimes sets Windows Wave output volume to zero.
-
-
- Fixed problems for Console conversion tool:
- When converting a big video file (>650 MB) with command
- line MMC, it prints superfluous characters (pp 20) when
- video encoding starts. Percent indicator jumps to next row
- from its correct place. After video encoding program prints
- out text: "dct: 0.000000 ms (0 calls)" that doesn't appear
- when converting smaller files.
-
- Installer:
- Installer now includes Java runtime environment and doesn't
- require pre-installed JRE.
-
- Uninstaller now cleans up the registry values the application
- creates and uses.
-
-
- System Requirements:
- ====================
- - Microsoft Windows 2000 with SP3 or Windows XP with SP1.
- - At least 500MHz Pentium class PC with 256MB RAM, 64K colors,
- 60MB disk space and soundcard.
- - User Documentation is in PDF format, so Adobe Acrobat Reader
- Software is required, which can be obtained at:
- http://www.adobe.com/prodindex/acrobat/readstep.html.
-
-
- Compatibility Issues:
- =====================
- - Note that video and audio support may differ between terminals
-
-
- Known Problems:
- ===============
- common problems for graphical and console tool:
- For some video codecs (e.g. DivX 5.0) MMC doesn't recognize
- the codec (UI states "unknown" but still plays
- and converts video correctly.
-
- Pre-processing MPEG-1 videos takes a lot of time.
- UI may appear to hang during pre-processing.
- Sound track may not be converted at all.
- Use other formats as input if possible.
-
- Canceling conversion when start time value is not
- 0 may cause meaningless error messages to appear.
- Setting start time value other than 0 may cause
- playback of DivX 5 to fail.
- Using video editing software to create the
- clip of proper length is recommended.
-
- Combination of XviD and AC3 codecs may not work
- as expected. If possible, avoid this combination
- as input format.
-
- Small max file size values (ca. 5kB) may cause
- "File Access Errors" during the conversion. This problem
- affects MPEG-1 video codec.
-
- Frame rate and intra period settings do not always
- affect file size as expected. Small changes usually
- won't affect file size at all
-
-
- Graphical conversion/viewing tool:
- When setting starting time at the end of an input file the
- program will crash when using quicktime codecs.
-
- Converter will crash without warning when sound card is
- missing
-
- When opening Apple Quicktime files in MMC "Audio format is
- not supported. Only video can be converted." message is
- shown to user.
-
- When sound card is disabled MMC crashes after trying to
- convert video or audio file.
-
- One can insert 0 to Max. file size box. Small values (e.g.
- 0-20 kB) don't have any effect when converting large video files.
-
- Size of MP3s encoded using variable bit rate is shown incorrectly
- in the GUI.
-
- MMC GUI sometimes sets Windows Wave output volume to zero.
-
-
- Console conversion tool:
- When inserting big (e.g. 50) values to intra perioid in
- command line version, MMC only prints out help text and
- doesn't show any message. Using parameter -intra in command
- line version of MMC doesn't work. User can choose to have
- intra perioid only from 0 to 9. Intra perioid values of 10
- or bigger are ignored even though 15 is the default value.
- MMC doesn't give any error message, it only prints the
- command line help.
-
- When choosing relatively small bit rate value (e.g. 10.000)
- in console version of MMC, the output file isn't encoded
- properly. Video jams every 4-8 seconds for 1-2 seconds and
- then plays normally 4-8 seconds. In other words: frames
- aren't placed regularly. The bigger the audio rate the
- longer the smooth video playback time and shorter the
- jamming time. Audio plays continuosly in any case.
-
- When converting video-clips bitrate option -br is not checked
- for validity. If -br value is invalid, soundtrack will not
- convert correctly.
-
- Using option -i crashes the converter.
-
- Command line converter doesn't accept .3gp-files as input.
