extracting both audio and video in real time
Has anyone tried to manipulate both audio and video from one mov file?
I’ve been using spigot~ object to extract the audio from video real time and control the manner of playback (SUCH AS REVERSE, SPEED, FRAME OFFSET) AND have the audio change come in sync to the actual video play back..
so far it has been half success, due to the difference between audio rate and the frame rate of quicktime. (either there is latency or system crash..)
if anyone knows smarter object to achieve this goal, could you please help me out?
spigot~ is ok, but its got its own temper…
i would try separating the audio from the mov and putting it in a buffer~. From there you can deal with the audio with MSP (which should make your patch more stable.
To sync the audio with the movie u could extract the current frame from jit.qt.movie and send that to a granular synthesis patch (for example…)

ps. since i updated the jitter API (see C74/incremental downloads), spigot~ works better – FYI, i’m still using max 4.6
Thank you so much!!
I will try that and let you know how it turned out
