4K for everyone

As a phoenix rising from the ashes, Sony introduced in 2012 a new format called XAVC. And with it, a 4K flavor that was embraced by all the prosumers, the XAVC-S

A well studied portfolio that covers all enthusiast's pockets along with the almost two years advantage reaching the market, was the key factor to its success.

The Sony FDR-AX series was its Trojan Horse to gain the leadership position in the 4K domestic recordings.

Repair your domestic FDR-AX XAVC-S recordings

Sony released on January 2014 their first consumer UHD camcorder, the Sony FDR-AX100. For the first time, thanks to this compact device, 3840x2160 30p video could be recorded by non professionals.

A bit later, Sony unveiled the Sony FDR-AX33 a smaller, lighter weight UHD camcorder with many of the same features as the AX100. And what was more important, an unbeatable price tag to reach the domestic market.

Finally, the professional-level Sony FDR-AX1 completes the portfolio with the evolution of the HDR-AX2000, using also the XAVC-S encoding with a maximum bit rate of 150 Mbit/s at 60p, or 100 Mbit/s for 30p and 24p recording modes.

Sony FDR-AX files are encoded using XAVC-S format based on MPEG-4 AVC/H.264 compression. Audio is recorded in 16-bit Linear PCM stereo at 48 kHz format.

SDXC memory cards class 10 U3, or higher, are required for XAVC-S 100 Mbit/s recording.

Damaged MP4 files cannot be opened because, despite media — video and audio — is present and not corrupt, the index and header of the movie indicating what the data means, is not. The repair consists in reindexing the content of the clip.
