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.
