=== Movie Tools (12/19/96) ===
[ Changes from version 1.98e to 2.1e ]
(1) MDEC encoding is now faster -- about twice as fast as version 1.98e
(2) Size limits for scripts have been removed.
(3) The frame number is now shown on the progress dialog box.
(4) A warning is now shown when the input audio data is not 16 bits per sample.
(5) Scripts are now case insensitve.
(6) A function Pcm2Xa has been added to the script.
(7) The number field of file sequence is now treated as 32 bit value.
(8) The str(RGB) format has been removed.
(9) '~' and '_' are now recognized as a part of file name by the script parser.
(10) A warning is now shown when AVI frames are compressed.
(11) 32 bit deep AVI is now supported.
(12) Q matrix setting has been corrected.
(13) While video is interleaved with audio, the str file is now created
even if the size of video frames is larger than the size the converter expects.
(14) Extra null sectors which had been appended to the end of
str file with the previous version of MovConv are not appended with this version.
(15) The value of the sub mode field of Video sector's subheader has been changed
from 0x42 to 0x48.
[ limitations ]
(1) Input AVI must be an uncompressed AVI. Audio must be 16 bits per sample.
(2) The preview functionality doesn't work well on a 4 bit or 8 bit display.
[ Known bugs ]
(1) The last frame cannot be shown on the MDEC Preview dialog box.
[ Changes from MovPack 1.2e to MovPack 1.5e ]
(1) MovPack script has been added.
caution:
See movpack.scr for detail.
Movpack script is processed line by line.
It may cause errors to edit the script over multiple
lines.
(2) The channel number is now set correctly when the video sector is
specified as termination data.
(3) The value of sub mode field of Video sector's subheader has been changed
from 0x42 to 0x48.
[ Misc ]
(1) Attached help file is obsolete. See below to check new features
of Movie tools.
=== New features which are not described in help file ===
[ Script ]
MovConv has batch processing cabability. A "script" defines the processing
sequence. The script for MovConv is very simple. It is a sequence of
functions which defines each conversion. Please see movconv.scr to
check syntax of MovConv script. MovPack also has script. It is a little
different from the MovConv script. Please see movpack.scr to check the syntax
of a MovPack script. The parser of MovPack script is much simpler than
MovConv script. Editing over multiple lines on movpack.scr may cause
errors.
[ Q matrix ]
Q matrix is a quantization matrix which is used in the quantization stage of
MDEC compression. The MDEC quantization stage is the same as the JPEG or MPEG
quantization stage. A full discussion is beyond the scope of this document;
please refer elsewhere for more details. Normally, you don't need to change the
Q matrix value . If you are very familiar with JPEG or MPEG compression,
you can change the Q matrix value to optimize compression.
[ Leap sector ]
A "leap sector" is a sector which is put on output data to synchronize video
with audio. To be exact, the NTSC video frame rate is not 60.00 fps but
59.94 fps. If you import video using video capture equipment, the base
frame rate of imported video is 59.94 fps. But the PlayStation streaming
mechanism expects video data to be 60.00fps. So, if you play this video
data with PlayStaion, it is played slightly faster than it should be.
Usually, it doesn't matter if you play only video data because the frame
rate difference is very small. But if you play audio data with video
data, you will recognize that the synchronization of video and audio becomes
gradually incorrect. You can solve this problem putting a leap sector on the
original 59.94 fps video. This makes 59.94 fps video 60.00 fps.
Please refer below to see whether you should or should not put in a leap sector.
