Support MIDI and dynamic change FRAME RATE

Question

What MACROMEDIA says about support by FLASH, midi files and
dynamic change FRAME RATE of the movie?
this is two nuances that does not suffice me.
And what about macromedia FLASH 9? When it comes?

Answer 1

For dimension changing use something like this (is a part of a bash script for video edition so ...) :
# Le quitamos el over-scan al ancho. OJO!! debe seguir siendo MULTIPLO de OCHO
WIDTH_SCALED=$(($OUTPUT_V_WIDTH-$OUTPUT_OVS*8)) #multiplicamos el overscan por 8(4 pixeles a cada lado)
# Obtenemos relacion de aspecto de forma mas precisa
if [ "$OUTPUT_V_ASPECT" == "1.7777" ]; then # formato panoramico
ASPECT_PRECISE=`echo "16/9"| bc -l`
else
ASPECT_PRECISE=`echo "4/3"| bc -l` # y el formato normal
fi
HEIGHT_SCALED=`echo "(${INPUT_V_HEIGHT}*${OUTPUT_V_HEIGHT}*${ASPECT_PRECISE})/${INPUT_V_WIDTH}"| bc -l`
# Necesito que el alto sea MULTIPLO DE CUATRO para que la longitud del PADDING sea PAR y simplificar el codigo... introduzco un error de 3.999999 pixels (en el peor de los casos)
HEIGHT_SCALED=$((`echo "scale=0 ; $HEIGHT_SCALED/4"| bc -l`*4))
# Calculo el Padding
OUTPUT_V_PAD_WIDTH=$(($OUTPUT_OVS*4))
OUTPUT_V_PAD_HEIGHT=`echo "scale=0 ; ($OUTPUT_V_HEIGHT-$HEIGHT_SCALED)/2"| bc -l`
Don't bother about the comments . Is spanish .
What you want is :
HEIGHT_SCALED=`echo "(${INPUT_V_HEIGHT}*${OUTPUT_V_HEIGHT}*${ASPECT_PRECISE})/${INPUT_V_WIDTH}"| bc -l`
About frame rate - this is video edition and i think you can not do this in java . Is more complicated than a simple calc . Under linux i'm using ffmpeg to change fps and encode from avi to mpeg2 .
