:: DESTROY MOTION GRAPHICS ::: Transform any video into extreme digital art. Play on the intoxicating fringes of glitch video with 37 exclusive video filters. Be creative. Push the boundaries. Legendary music label Detroit Underground presents a totally new tool by the creator of DECIM8, designed to digitally mangle and twist your videos. DU-VFX is an experimental app for experimental people. The line-crossers, the button-pushers, the ones who don’t fit into basic boxes. Load up any video from your camera roll. Tap the randomize effects button. Find a VFX filter combination that makes your content POP - or explode into digital fragments of its former self. Scan through the frames of your video and export any affected frame as a still image. Activate and arrange the effects stack manually or rely completely on the nature of chaos - the choice is yours. • Load any video from your camera roll as source material • Apply 37 insane video filters in infinite combinations • Arrange and activate a video effects stack manually • Blend the glitched-out version with the original in 22 blend modes • Randomize filters for unique chaos • Optionally, parameters can drift and change over time • Save any effected video frame as a still image WARNING! THIS APP IS CAPABLE OF COMPLETELY DESTROYING A VIDEO. (You keep the original, of course!) If this doesn't appeal to you, there are LOTS of apps out there to provide all the "safe" effects you could ever want. If you're looking for something more, something new and unpredictable.. capable of making art that's challenging yet beautiful, then you are in the right place. Note : Currently video rendering must happen while the app is in the foreground. iOS may kill the app if backgrounded during render. We're looking into the best way around this.
