- 20. _M_e_d_i_a__C_o_n_v_e_r_t__T_o_o_l
-
- Media Convert (invoked as _m_e_d_i_a_c_o_n_v_e_r_t(_1)), is a digital
- media file conversion tool that provides a simple user
- interface for creating movie, audio, and image files from
- other movie, audio, and image files. Media Convert replaces
- the tool ``Movie Master'' which was introduced in the IRIS
- Digital Media Tools version 5.4 (WebForce 1.0).
-
- For more details, consult the manual page, or the on-line
- help which is available from within the tool. In addition,
- you may want to refer to the documentation for _d_m_c_o_n_v_e_r_t(_1),
- since Media Convert invokes dmconvert for the actual file
- conversion operation. Most new features and bug fixes for
- dmconvert will also apply to Media Convert.

- 20.3 _C_o_n_s_o_l_i_d_a_t_i_o_n__o_f__T_o_o_l_s
-
- In IRIX 6.4 as in IRIX 6.2, _m_e_d_i_a_c_o_n_v_e_r_t and _d_m_c_o_n_v_e_r_t have
- been enhanced to provide a superset of features that were
- previously available from numerous older programs. Users of
- the older programs will find the following backwards
- compatibility support.
-
- The graphical tools, _s_o_u_n_d_f_i_l_e_r(_1) and _m_o_v_i_e_c_o_n_v_e_r_t(_1), are
- now symbolic links to _m_e_d_i_a_c_o_n_v_e_r_t.
-
- The command-line tools, _a_i_f_c_2_a_i_f_f(_1), _a_i_f_f_2_a_i_f_c(_1),
- _a_i_f_c_c_o_m_p_r_e_s_s(_1), _a_i_f_c_d_e_c_o_m_p_r_e_s_s(_1), _a_i_f_c_r_e_s_a_m_p_l_e(_1),
- _s_f_c_o_n_v_e_r_t(_1), and _m_a_k_e_m_o_v_i_e(_1), are all still available, but
- have been re-implemented to internally invoke _d_m_c_o_n_v_e_r_t.

-
- 20.4 _R_e_l_a_t_e_d__T_o_o_l_s
-
- MMMMoooovvvviiiieeeeMMMMaaaakkkkeeeerrrr((((1111)))):::: Graphical tool for editing movie files. Not
- primarily intended as a movie conversion tool, however there
- is an Export Options panel which allows user to set various
- export file format parameters. Tool supports SGI Movie and
- QuickTime (including Cinepak) movies. Will not read MPEG
- movies.
-
-
- 20.5 _K_n_o_w_n__P_r_o_b_l_e_m_s__a_n_d__W_o_r_k_a_r_o_u_n_d_s
-
- This section lists problems in Media Convert and ways to
- work around them.
-
- +o If you are converting a QuickTime movie which contains
- non-uniform frame durations, Media Convert will always
- generate a movie with a constant frame rate.
-
-
-
-
-
-
-
-
-
-
-
- - 3 -
-
-
-
- Therefore, the size of the output file may increase
- because Media Convert may duplicate source frames into
- the output file. To work around this problem, be sure
- to set the frame rate in the "Video Output Parameters"
- dialog when you use a QuickTime movie as an input file.
-
- +o If you specify an SGI movie file as output, the
- progress indicator bar may show 100% completion, and a
- delay on the order of a minute may occur before writing
- the SGI movie file has been completed.
-
- +o You cannot create a JPEG Cosmo compress movie from a
- source movie with an odd number of pixels for the
- height. You will first need to convert the source
- movie to a movie with an even number of pixels for the
- height, and then the intermediate movie file can be
- used to create a Cosmo movie.

- 20.6 _C_h_a_n_g_e_s__f_r_o_m__P_r_e_v_i_o_u_s__M_e_d_i_a__C_o_n_v_e_r_t
-
- This section lists the changes in the functionality and
- interface of Media Convert from the versions shipped with
- IRIS Digital Media Tools 5.4.
-
- +o The "Open Input File" dialog is now dismissed after a
- file is selected.
-
- +o You can directly combine an AIFF audio file with an
- MPEG video file.
-
- +o The default output settings for converting to MPEG is
- MPEG-1, Layer II.
-
-
- 20.7 _B_u_g__F_i_x_e_s
-
- This section lists the bugs fixed since the IRIS Digital
- Media Tools 5.4 version.
-
- +o It is easier to type in a path name in the input file
- text fields.
-
- +o You can now specify input files containing a "#"
- character in the file name.
-
- +o Media Convert can accept QuickTime movies which have a
- non-integer frame rate.
-
- +o You can now drop a QuickTime movie file with audio
- tracks into the Audio drop pocket.
-

- - 4 -
-
-
-
- +o The output parameter settings are now "sticky." They
- remain unchanged until a new input file is specified.
-
- +o The default name for the output file now gets an
- automatic suffix corresponding to the output type.
-
- +o Media Convert no longer prints an error message if
- Cosmo Compress is not installed.
-
- +o If Media Convert should run into an error while
- performing the conversion (running out of disk space,
- for example), or if the conversion is cancelled before
- it is completed, the incomplete file is now
- automatically deleted.
-
- +o Media Convert handles the error condition if the output
- file specified cannot be written or created.
-
- +o Media Convert now warns the user if the output file
- will be over-written.
-
- +o Media Convert provides better user feedback if a
- necessary CODEC license is missing (such as Cinepak or
- MPEG).
-
- +o Media Convert works on smaller displays, because the
- output parameters settings are displayed in a separate
- dialog box, instead of expanding the Media Convert
- window.
-
- +o Media Convert now correctly converts an MPEG movie file
- into a sequence of image files.
-
- +o A problem which caused Media Convert to fail to create
- a JPEG SGI movie format file has been fixed.
-
- +o Movies created from Cosmo Compress JPEG movies have
- improved image quality.
