The JVC GC-XA2 ADIXXION Full HD Action Camera is a lightweight and rugged action camera that is compatible with a variety of optional mounts for use in a variety of conditions, environments, and activities. Highlighted by JVC’s “Quad Proof” design, the GC-XA2 is waterproof down to a depth of 16.4′, shockproof from falls up to 6.5′, freeze-proof to temperatures as low as 14°F, and completely sealed off from dust penetration thanks to an IP6X dustproof rating. It also features a fixed focus, 160° wide angle lens with a bright f/2.4 aperture. Plus, you can use the integrated 1.5″ LCD monitor for shot preview and instant playback.

The GC-XA2 employs H.264/ MPEG-4 AVC compression method and stores video recordings in an MP4 wrapper. According to JVC, the GC-XA2 Full HD Action Camera works with iMovie/Final Cut Pro X. However, due to user feedbacks, sometimes iMovie/FCP X can’t handle the GC-XA2 MP4 footage stably and reliably. That’s mainly because H.264 is a codec ideal for capture and delivery, but not quite suitable for editing.

In order to make iMovie/FCP X recognize GC-XA2 60p video well, you’d better convert the 1080/60p to Apple IntermediateCodec (AIC)/ProRes codec, which iMovie/FCP X will read and handle well. To performance format conversion, third party software is required. Considering the ease of use and excellent output quality, you can give HD Video Converter for Mac a shot, which is fully compatible with the most recent Mac OS X 10.10 Yosemite.
