Why wont my crossfade work?

    May 11 2011 | 12:57 pm
    Here is the sub-patch ive written based on the tutorials, though for some reason it wont work. I understand MaxMSP but when it comes to jitter I am useless; all i want to do is crossfade between two still jpegs...
    Thanks A

      Don't worry too much about it, a couple of months ago I had the same kind of very basic issuesm just hang on and you'll get it eventually.
      The biggest problem is that you don't have a metro/qmetro. A metro for movies typically has an argument between 30 and 40 to bang out frames in the movie. Try giving a high metro argument and you'll get to know it.
      Here's a fixed version of your patch.
      Maybe you could try to make a small GUI? Possibly with a slider rather than numbers.
      Check out learn and video processing device. That will give you some jitter help.

      Oh... Looked at it again. Your bang and your prepend xfade has no practical value either. Good luck with it!

      You need to either constantly bang the respective image matrices and xfade object to generate a new resultant image - triggered by any change in the numerical xfade value OR use the more traditional approach of "polling" jitter matrices via a (q)metro as I've done here:
      And once again, In the process of responding, I missed previous posts answering the question already 8-O

      Ah brilliant, thats great; didnt realise it needed a constant bang to remind it to do something! Thanks!

      you don't actually need the continuous bang...just add a bang after you send a new xfade value:
