Mutiple Video into Vizzie?

Hey

Im trying to do a piece of work which has 21 different videos.

Video 1 is used like a backdrop which will come in and out when all the other videos arent being used.

I am using pressure mats to activate the other 20 videos. My questions are:

1) Can i put all 21 videos into vizzie without having them all on the screen at the same? (This completely slows my computer down!!)

2) I need some sort of argument to say if someone is pressing video 1….and someone else is pressing 2…(which can be cross faded images)…a third trigger cannot happen for say 4 seconds then after 4 seconds…..what ever gateways are open will take over 1 and 2. (HOPE THAT MAKES SENSE!!)

3) Am i better using jitter in max to try and do this? I did try and use 5 of the 4 mixer patches in vizzie but then i couldnt work out how i might solve question 2.

Any help would be much appreciated..Im going round in circles…

You can use the MOVIEFOLDR module to load a folder full of movie files. You can load as many PLAYR modules as you’ll need (never more than what? 5 or 6?) at the same time and send the inlet of the MOVIEFOLDR a number between 0. and 1.0 to load a movie (if you want to choose ’em by number, a common scale object should translate the number of movies in your folder to the index to load the film – e.g. [scale 1 25 0. 1.]

What you described in 2 isn’t at all clear, but you’d probably just make that part of the patch in straight Max. Since Vizzie modules are all bpatchers that share a common small set of messages, that should be stupid simple. It was designed that way. And the next version of Vizzie will allow you to treat all Vizzie modules as plain old Max abstractions, which should simplify things a bit [or at least save screen real estate]. In the meantime, apart from a little Max glue, you should have most of what you need in Vizzie. The rest is some timers and gates and trigger objects.

hm.

Can you be more specific? What kind of machine are you on? What version of Max? What OS?

When you drag a folder onto the top of the menu object, what kind of error message (if any) do you see in the Max window?

As usual, more detailed information about your problem will always get you better answers.

I am on windows 7. And I can never drop files. I have always to use the read message to make sure that jit.qt.movie will read the movie. I have trash my preference and it doesn’t work either. Is there a workaround like a read folder message available ? I don’t know if it’s the case with other people but my qt is not working well : I have try everything, download again and reinstalling everything. My workaround is to run Max as an administrator it works for almost every QT functions except the drag and drop

Okay. You’re on Windows. What version of Max are you running?

The rest of your note sounds as though the dropfile object *itself* is not working properly. Is that what you’re saying [In other words, does the help file for the dropfile object work properly for you?

Try this example (it’s basically the code from the module). Drag a folder into the little square, then check to see if the menu loads.

Then, hit the button to clear the menu. Put the patch into Presentation mode and then try it again….

Drag and drop isn’t a QuickTime function, by the way.

Ive attached my patch so far…..

I have put 4 of the MOVIEFOLDR things in as im going to have to set up a gateway system before them for the numbers ive got underneath.

The argument thing from my second question…

So I have 4 players as I need to split my numbers between 1 and 20 which are seen in the message boxes.

I want to have a maximum of 2 videos being played at the same time. So i need some way of setting up a system whereby only 2 can be played, if a 3rd is pressed it is stored for a time period (say 5 seconds) to allow the videos being played to run for at least 5 seconds themselves…if it not played within the allotted 5 seconds it is forgotten??

Ive then put a switcher at the end to try and somehow switch between the single PLAYR and a mixed video from the 4MIXR. Although im not sure this will be the best thing to use.

The pasted thing pastes completely incorrectly in my version of 6. Could you perhaps consider selecting what you want to include/post and the choose "Copy Compressed" from the Edit menu and post *that,* please. Since you’re still not at all clear, I think I’ll have to see stuff.
