(SR5) Sony A7s records 4K in XAVCs codec and with 4k clean output .

Share

A7s records in XAVCS format which is a consumer version of the XAVC format (see some of the main differences above).

According to two of our sources the A7s records 4K using Sony’s XAVCs codec. From Wikipedia:

“XAVC S supports resolutions up to 3840 × 2160, uses MP4 as the container format, and uses either AAC or LPCM for the audio  As example use in Sony FDR-AX100 4K Ultra HD consumer camcorder.”

A source also told me the camera has a clean 4K clean output but doesn’t record a clean 4K on SD cards. The source didn’t specify if with “clean” he means 4K at 10 bit and 4:2:2. Also same as the main competitor, the Panasonic GH4.

Note: The FDR-AX100 has following recording options and I guess these will more or less match with those of the A7s:

UHD 4K
XAVC S
3840 x 2160p / 30 fps
3840 x 2160p / 24 fps

High Definition
XAVC S
1920 x 1080 / 60 fps
1920 x 1080 / 30 fps
1920 x 1080 / 24 fps
AVCHD
1920 x 1080p / 60 fps
1920 x 1080p / 24 fps
1920 x 1080i / 60 fps
1440 x 1080i / 60 fps

MP4
1280 x 720p / 30 fps
