If your creative expressions include mixing and cutting videos, then you're going to love vjay, the latest app from the folks at Algoriddim. The company's known for its popular djay app, and it has brought a similar experience to video with vjay.
The vjay app leverages the processing power of the iPad (current or previous-gen; it does not work on the iPad 1) and lets you mix two video clips on the fly. The app ties into iTunes and lets you select videos and audio clips from your library. You can also record your own source video using the camera on the iPad. If you don't want to bother with all that, Algoriddim includes a handful of stock clips for you to use.
Once you select your video and audio, all the mixing is done in real-time, so there's no worrying about splicing at the right frame or picking the perfect transition. The app uses two scratch pads, one for each video, and has a center mixing window where all the action happens.
Each scratch pad has a variety of effects that you can add to your videos on the fly. You can add a strobe, twirl, fisheye, and crush. Moving your finger on each video scratch pad will adjust the effect as well as let you speed up or slow down the clip. You can also run the clip in reverse.
The mixing window also has several transitions that control how the final, mixed video appears. You can blend the two videos and use a slider to adjust the blend from one video to the other. There's also cube, grid, swap, push and mosaic transitions that let's you get creative with the your final clip.
While mixing, you can record the video and save it to your camera roll. For live VJ sessions, you can output the app's mix to a TV using an HDMI cable or stream it to an Apple TV using AirPlay.
You'll spend $9.99 to get vjay; it is available now in the iOS App Store. If you have even the slightest inclination towards playing with video, you're going to love vjay. Not only is it a blast to be able to mix videos on the fly, the performance is amazingly smooth on the iPad 3. I didn't see any perceptible lag and any stuttering was from user error. More than once in the middle of a mix, I clicked on the wrong effect or slide the mixing slider too far to the left or right, but that's all part of the fun.
