The MUVI K-1 and K-2 Sport both do a great job filming tennis. Whether you are a player, parent or coach, these workhorse cameras are easy to use. Both are wi-fi enabled and give you a secure connection between the camera and any Apple or Android device. No internet is required – the connection is just between the camera and your device.
The following table compares some of the major feature of the K-1 and the K-2 Sport cameras.
Comparison of K-1 and K-2 Sport
|Battery Life||3 hrs||2.5 hrs|
|480 at 120 fps||Yes||No|
|720 at 30 fps||Yes||No|
|720 at 60 fps||Yes||Yes|
|720 at 120 fps||No||Yes|
|1080 at 30 fps||Yes||Yes|
|1080 at 48 fps||No||Yes|
|1080 at 60 fps||No||Yes|
|USB Charging Cable||Yes||Yes|
|Date and Time Stamp||Yes||Yes|
|Record when Charging||Yes||Yes|
With the K-1, using the 32 gb card that we provide and shooting at either 720p, 30fps or 1080, 30 fps, the card will hold 5 1/2 hours worth of video. You can double that recording time by using a 64 gb sd card.
With the K-2, using the 32 gb card at 720, 60 fps the card will hold 13+ hours. At 1080, 60 fps, the card will hold 7.5 hours.
In summary, the main difference between the K-1 and K-2 are:
1.) with the K-2 you can squeeze twice the recording time due to it’s more efficient file structure. Great if you are filming more than 5 hours in one day.
2.) the K-2 can film up to 120 fps at 720p, generally more than adequate for any slow motion study. The K-1 can film at 120 frames per second, but the resolution drops to 480p (still pretty good, click here for an example).
3.) the K-2 Sport has a carrying case.
4) the K-2 has a slight edge when filming in low light situations, but both work well indoors. The “slight edge” is honestly hard to distinguish.
5) File size of the K-1 is 30 minutes and 15 minutes for the K-2. Still, the K-2 holds twice as much on an sd card as the K-1.
In our experience, the K-1 and K-2 both work exceptionally well for both match play and for technical stroke analysis. To extend the recording time on either device, an Anker External Battery works great. With the 3350 mAh model, just plug into the USB port and walk away for five hours. For an all day recording, use the 10,000 mAh model. Put your camera up in the morning and take it down at the end of the day. We’ve recorded 17 hours straight in one test! It’s great because you don’t ever have to worry about missing a match.
