With over the air tuners, a common concern is how fast the device is able to switch from one channel to another. I’ve already seen the question come up a few times regarding the Amazon Fire TV Recast so I recorded a quick video showing how fast the channels switch. As you can see, channel flipping on the Recast takes about 2 seconds. The channels used in the video were live and unbuffered. The Fire TV Recast was actively recording a different channel while I conducted the test. The video is unedited, so the timing of everything is exactly how it is when using the Fire TV Recast.
