Hello List,
I'm trying to synchronise film and it's sound in pd. I have several
short clips exported as one longer video and separate audio file. I
need to be able to start each one of them when I choose, but I loose
synchronisation of sound an video. I first try to use this patch
(http://www.youtube.com/watch?v=boX0v54SqtU ) - I send to the right
inlet of [phasor] the starting point of the video (/) by the total fim
length. That worked with one of my video test, but with the real video
that I have to use totally lost synchronisation. I
send separately the begging point of the video to [counter] and [pix
film]. Then I tried to use [phasor] as the play machine for both. But
it still doesn't work- the problem this time is the speed of the sound
sample is faster and the way the films change is pretty random, but
there is synchronisation.
I attach part of my second try. I hope that will be enough to see
where I' wrong
Thanks
Albena

To synchronise movies and sounds, you need to do the same thing
presented in the youtube video (with [snapshot~]). Then you need also to
know how many frames per second there is in your movie. For example, if
your movie has 25 fps and your sound is at 44100 Hz, then you need to
divide the value from [snapshot~] by 44100 (to get time in second) and
multiply this time by 25 to get the frame that must be reached (you send
this value to the right inlet of [pix_film]). Then :
[snapshot~]
|
[/ 44100]
|
[* 25]
|
[pix_film]
Hope it helps.
