这是一个iPhone应用程序，让你能控制视频拍摄，有可选的焦点和曝光，重要的是还可选择24P和25P，可以达到1fps。

售价2.99美元。

 This little iphone app which gives you nice control over the video camera, two selectable points for independent focus and exposure points but crucially this adds selectable frame rates of 24p and 25p as well as all the flavours down to 1fps!
A really great app, BUT you still need some sort of handgrip for it to get past that hideous rolling shutter issue the camera has! It has other features that you may or may not use, less essential but cool. Slate, bars, crop marks. It is still an iphone but having this control makes it a much more usable tool, a controllable video camera that you always have on you. I left my Zacuto Z-Grip thingy at home as I have other cams with me so I can’t really film anything properly with it, I shake too much…Nice to have 25p though and full control…heck even audio meters on screen. My Canons don’t even have that!
It’s only $2.99 so a bargain! Enjoy!
