this video consists of the first experiments with diachronic blending – developed in processing -, by pedro veneroso. this particular video is composed of four different manipulations of the same video sequence and represents the first test of the software.

the diachronic blending effect consists of merging frames on a time progression using a set of different merging techniques blending an array of frames individually each time the screen is rendered. the outcome is a fluid and distorted succession of images that vaguely document the way in which movement evolves, while transfiguring both actions and forms into mutable and organic shapes.

furthermore, for this particular video a 'blur' class was created to implement randomly generated blur to each frame of the video on an attempt to develop organic-ish forms based on movements of rigid structures.

so far the code for the software that will control this effect is still under development; as soon as we have it done we will release both the source code and the software at http://www.marginaliaproject.com

for these experiments we used raw footage of the feature film 'os residentes' [yet to be released], by tiago mata machado. actress simone sales brushing her hair violently.

this experiment was made within the context of marginalia project. more information about it, as well as the source code of this software [soon], can be found at http://www.marginaliaproject.com

Pedro,

That's excellent. Now a quick question: can your code extract individual frames from a video and display it? Say I want frame  233 displayed on screen can I do it with your code?

well, i usually export a jpg sequence from final cut or quicktime and deal with individual frames this way [interpreting them as images numbered in a sequence and calling each frame when i need it]. this code i am developing focuses on my own production, so i don't think that this time i will implement anything that could make dealing with individual frames easier. working on the [a new] video library for processing is actually something i am thinking of doing in the future, specially to allow faster response on real-time video capture, playback and analysis.

anyway, you should check the function jump() of the video library. it allows you to define a specific point in a video to jump to. you could use it to grab a specific frame [i think you must pass the actual second you want to gather as a float; you could create a brief algorithm to make it more flexible, allowing you to pass the actual frame number instead of sec].
