How to playback a folder full of images as a movie, as it is updated?

August 26, 2010 | 7:15 pm

I have an application that records a sequence of images in a folder, over time.

I’d like to play back these images continuously as a movie, even as images are being added.

I have found the images2movie and packpicts demo patches, which are useful, but very oriented towards doing a one-shot conversion. I would like to be able to scrub back and forth through the images immediately, and not after a conversion process.

I suppose I could use a (metro) to refresh a (folder) object at regular intervals, load it into a (umenu) and then index into that, but I have concerns about a) having too many images and b) the time it would take to constantly refresh the (folder) object.

Is there any way to set up a "watched folder" type scenario, where the patch gets a signal whenever the contents of a folder have changed?

Is there a better way to handle image sequence playback?

Have a look at this patch. I posted that a while ago to detect when the contents of a folder changes. Haven’t looked at it since… but it might put you on the right path.
You might also want to think about jit.matrixset for keeping track of your pictures…. search the forum for some good examples.

Thanks, that looks very helpful! I did not realize that (filewatch) existed, and that it could monitor changes to a folder!

This post seems to contain a broken pasted patch. This can happen if you don’t copy the entire "———-begin_max5_patcher———-" or "———–end_max5_patcher———–" for each and every patch you paste; perhaps you missed a preceding or trailing "-" when you copied the patch? Please notify the Cycling 74 web team if you think it is a bug.

What you see is the patch in compressed form to enable sharing on the internet.

Copy the code from the webpage, starting with the "begin_max5_patcher" line and ending with the "end_max5_patcher" line, then paste it into an empty patch in Max. The patch should appear!

Hello,

you mentioned the images2movie and packpicts demo patches. Where can I find these? Im trying to get a movie running from an image sequence in the hope it will take less computing power. Could someone direct me to the patches mentioned above or does someone have a better idea to make a patch less heavy. In addition to other operations it simultaneously plays 6 different movies and switches between them. I have a test version now with smaller movies, but the real movie will be about 500mb big (thats why i though od image sequences). Any suggestions?
thanks, Rik

The image2movie and packpicts patches are in the examples folder that comes with Max. For example, on the Mac, for Max 6, they are in the following locations:

/Applications/Max6/examples/jitter-examples/demos/image2movie.maxpat
/Applications/Max6/examples/jitter-examples/video/quicktime/packpicts.maxpat
