I'm editing some animation clips to audio clips created in ableton.
When I play both audio and video clips together using ableton and resolume at the same time they don't stay in synch whatever settings I've tried.
I have midiclock being sent to resolume from ableton and I'm using the max patches to trigger the clips in resolume.
The clips in resolume are set to play at BPM and the correct number of beats specified. More importantly, they are the same length as the audio clips.
They always get out of synch after a short while. Any ways to remedy this?
thanks
resolume and ableton out of synch
Re: resolume and ableton out of synch
how are you triggering the clips at the same time? is this happening on the same computer?
I would recommend separate machines linked up via ethernet with a midi note from the ableton session triggering the clip in arena...
that being said... the bpm sync is not going to work. use smpte instead

Re: resolume and ableton out of synch
I guess I could explain myself a little more...
While MTC "works" it drifts... ever so slightly... and not for long... but it does. this drift is more than enough to let the audio and the video to fall out of sync with each other.
BPM sync over MTC and running the max patches have NEVER given me skipless, frame by frame playback when trying to marry ableton and arena.
heres what has.
1. resolution is an issue here... if you would like your videos to play back in perfect sync while you speed up and slow down the audio you will need to send a message that has many points of resolution... the only one in ableton I have seen work is an envelope on the pitch bend... set a envelope on the pitch bend to ramp from 0-the max value which if I remember correctly is 1000... then in arena make it so that the transport of the clip is midi mapped to the pitchbend clip in ableton... this will force resolume to playback the video at the exact rate ableton is moving the pitch envelope...
this is the ONLY way to achieve 100% sync that I have found which allows you to do shit like speed up and slow down your audio with no jumps...
there are caveats... which you will soon discover...
another way... generate smpte... much info on this avail I will not bore you.
another way... trigger the video and audio simultaneously with a midi note and compensate for the delay with ableton track delay... usually its about .33 ms ... you will not be able to ramp bpm in this situation... but if you dont touch it... it will play back synced.
I am sure there are other... more clever ways to sync audio and video... but these are the methods I have found satisfactory for a mission critical environment.
the easiest way is to break the clip up into sections practice and launch them yourself

Re: resolume and ableton out of synch
Thanks for the response.
What I'm actually trying to do is way simpler than what you describe.
Yes I'm working on a single machine running both Resolume and Ableton. Triggering is not a problem, this seems to work without visible delay most of the time. The problem is the video loop coming out of synch with the audio loop. I'm not speeding up or slowing down anything. The audio loop was created at 124bpm and played back at the same bpm. The video loop was created at 124 bpm and played back at the same bpm. The beat counter lights in Resolume are in time with the audio yet the video drifts which I can't really explain if the bpm is following ableton. Both audio and video have 8 beats, they are played at the same BPM yet they drift.... which is unexplainable really. Even if the video drifted up and down slightly it's overall length should always remain the same: ie 3.87 secs yet this is not the case
The only way I've found so far of synching audio and video perfectly is to use only Resolume with AV clips but this comes with degraded audio quality, glitches when switching clips etc...
thanks for the tip: " the easiest way is to break the clip up into sections practice and launch them yourself " but I was doing this back in 2002, I was hoping that more than 10 years later and with "devoted" av software doing something as basic as playing two audio and video clips of the same length, at their native speed in synch would be possible!

Re: resolume and ableton out of synch
Ive noticed that the Bpm sync would drift alittle on certain machines. BPM is tied into the sound card, play around with the audio buffer, I found that would fix things for me sometimes. I ran across this when sorting out an issue with some corrupt sound drivers a month ago.
Re: resolume and ableton out of synch
is the frame rate of your video locked to the framerate of your output? sometimes i notice i mistakenly rendered a loop at 24fps instead of 30 or 60 which plays nicer with my output
the pitch envelope method should work for ya here... its one extra step but is nice because it voids using resolumes crappy bpm analysis.
also... remember that for whatever stupid reason resolume jumps around with loops sometimes...
might want to try out touchdesigner for a smoother sync
