Software needed for this step
of DVD conversion:
[MS
MPEG4v3 Codec Package]
[aMPEG2AVIGUI
Release 1.45 (includes all tools)]
MPEG2AVI is a package
for a) those who know
what they are doing since a
lot of knowledge about frame-sizes,
rates etc. is needed and b)
those who want to get the movie
done in no time. (A friend
of mine will soon get an Athlon
~900 and from calculation this
machine should be able to do
conversion in real-time).
Follow this guide and it should
to the trick:
- Download the MPEG4 Codec
and run the executable.
(install all codecs that
are offered)
- Download the aMPEG2AVI Package
and unpack it into a directory
of your choice.
- Make sure you already decrypted
all the files to your harddisk
- Fire up FlaskMPEGEncoder
(this can help you determining
the right cropping values)
- Choose your VOBfile with
File->Open
- Choose any audio
stream in the selector
(doesn't matter now since
we only want to get some crop
values)
- Choose menu Options->Global
Project Options
- Select tab Video
- Enter appropriate framesize
into Frame Size and select
appropriate Frames per Second
!
PAL: 720 x 576 @ 25
fps
NTSC: 720 x 480 @ 23.976
fps
- Check the box MMX iDCT
if you have an MMX processor
- Select tab Post Processing
- Check the box No letterboxing
- Check the box Keep aspect
ratio
- Push the button Show
Output Pad
Reduce Height until lower
black bar is gone
Increase Top Offset
until upper black bar is gone
Note:
With newer FlaskMPEG Version
you may use drag'n'drop on
the frame around the picture
to get the right values !
If you can't get the image
to correct size at first just
do the same procedure again..Reduce
Heigt -> Increase Offset
until you only see the movie-picture
in the window
Push the button Hide
- Now keep the values you
find in height and width in
your head or on a piece of
paper !!!
- Fire up the aMPEG2AVI-GUI
NOTE:
After first installation it
may be neccessary to set all
the paths to the binaries
which lie in the directory
$aMPEG2AVIPATH\bin
To get into the configuration
dialog press F11
- Press F6 which will
open the File-List Editor
- Add all the files of your
DVD, order them and hit Save
and Set
- In the part of the GUI called
Profile Details enter
the FlaskMPEG Values
Crop @
Width x Height
- Set Downsize X to
720
Set Downsize Y to the
same as height
- Click button Start Preview
- It is almost sure that the
picture won't fill the screen
so increase Downsize Y
- Again click button Start
Preview
- Do the above two steps
until the picture looks okay
- Go to the GUI at Advanced
Options
- Select the appropriate framerate
(fps)
PAL: -f2 [25]
NTSC: -f0 [23.976]
- Set output format
to -o8 [AVI-YV12-4:2:0]
(the output format setting
is cause for aMPEG2AVI being
faster than the older FlaskMPEG
releases)
- Set reference quality
to -r12 [16-bit MMX ChiDCT]
- In [File Locations]
set the destination path in
OUTPUT
- Check the box HQ bicubic
filtering
- Check the box Enable
MPEG2AVI PX3 Mode
- Check the box Decode
Only AC3/MP2 Stream
- Select your desired languageright
to the checkbox
NOTE:
0x80 is mostly English
0x81 is mostly your local
Language
- For a final preview hit
Start Preview
- Now hit Start Encoding
- The AVI Compression Dialogue
will appear
- Choose DivX Codec 4.01
Codec and hit Settings.
- Use the Quality slider and
move it to 100 (Crispness)
- Set Keyframes every 4 seconds
- Set bitrate to the bitrate
calculated by my Bitrate
Calculator.
- Hit Okay twice and conversion
will start.
NOTE:
As you see this procedure is
a bit more complicated. But
believe me, you will get used
to it and the results are amazing
! As I stated earlier a movie
reaches ~12 fps compression
speed on my old Ahtlon 500.
Not too shabby compared with
~6 fps in FlaskMPEG !
