Best way to trigger one very long midi mapped clip

Hi -

This is a bit of a slightly unusual approach but my thing is - i vj for a three piece psychedelic funk band - and i wish to trigger three very long video tracks - One for each song - the video has been pre- prepared and are synced exactly to the bands music.

I have three pre prepared videos set up this way - all about 8mins long. We did a gig last sat that we mapped from the keyboard players cuebase software.

In the practise before the gig they all triggered fine, but in the gig only one went exact - the other one stopped half way through and the other went out of time by a few seconds - which ofcourse blow the magic.

They were all mapped to the bottom layer in resolume avenue - with no other clips mixed in.

My question is perhaps for such long clips Dxv is not the best codec to use as they are such huge files.

and is there anything else i should of checked before - such as trigger mode - also i think perhaps the midi clock was on - which as the songs are played exact to the video already was not needed.

Its the first time iv done any mapping so all a bit new.

In time we hope to break all the music apart and sync the midi mapping up properly.

But for the time being a just wanted to use one long canvess layer.

The band consist of drums, guitar and keyboard synths etc

Any pointers greatly appreciated :)

Although we still think that DXV is the best codec regardless of length or resolution, if you're just looking to play back files linearly, you could some tests with H264.

In general you'll want to get the midi clock from Cubase, and then set the clips to BPM sync and the amount of beats that they last. That way you'll be sure that they measure up exactly. Normal playback can drift a little depending on system activity.

Hope that helps.

Thanks Joris - Yes indeed it really helps...

I will be getting together with the band later hopefully this week and we can run through it all again..

The wknd gig all happened at break neck speed - litrally doing the mapping an hour before the gig.

So now we have a breather of a month to our next gig - we can really run through this new exciting midi mapping malarky...

I thought we might try also mapping the song in one min segments along the way so should it go out of sync it has a chance to resynce again as it moves along..
Will give it a try anyway along with what you suggested about the measure of beats and snapping them in- to the beat snap..

Many many thanks- will let you know how we go :)
