New Sony FDR- AX1 Announced
All Sony ecosystems are called upon to promote 4K, as there was little 3D, from cloud services PlayMemories until the PS4. Some choices Sony for its FDR- AX1 are sometimes a bit surprising for a camera that still costs 4 € 499.01. For example it uses the codec XAVC S placed in a MPEG4- AVC / H.264 container. It is a variant of the more compressed the XAVC/H264 Level version 5.2 codec. More bad news for users who want to go further than holiday movies on YouTube, the colors are sampled 4:2:0. Without going to a 4:4:4 coding or even RAW images, 4:2:2 would have left a significant latitude for color correction, calibration, clipping paths and masks, and other special effects and overlays on " green funds".
The FDR- AX1 seems quite clear heat, after initial tests published on the Net. The XQD cards would be hot when removed from the camera. Similarly, AX1 which manages large data flows, processes and compresses, heat up quickly despite the internal fan which it is equipped. This also may be a concern for the sound by the internal microphone of the camera emits noise. This should not pose any problems to professional users, resorting instead to external microphones for their shots, but for the general public or semi pro users, high heat and fan trying to remedy it may hinder the sound made with the built-in microphone on the camera.
