Key facts

Recording media: SDXC (UHS-II)
Published recording modes: 42 normal, plus 105 slow motion
Highest bitrate: 600 Mbps: XAVC S-I 4K at 59.94p (4:2:2 10-bit)
Lightest 4K mode: 30 Mbps: XAVC HS 4K at 23.98p (4:2:0 10-bit)
Card for the top mode: V90. Sony lists: SDXC V90 or higher
128 GB card at 4K 30p: 1 hr 55 min in XAVC S 4K at 29.97p (4:2:2 10-bit, 140 Mbps)
Top frame rate (normal video): 119.88p at 4K and 1080p
Slow motion (in camera): Yes. Up to 120 fps at 4K, 240 fps at 1080p

"4K 30p" means the highest-bitrate 4K UHD mode at 29.97p or 30p that a V30 card can record (240 Mbps or less). If there is no 30p, we use 25p, then 24p.

Quick answer

A 128 GB card holds about 1 hr 55 min of XAVC S 4K at 29.97p (4:2:2 10-bit, 140 Mbps) on the Sony A6700. The heaviest mode, XAVC S-I 4K at 59.94p (4:2:2 10-bit, 600 Mbps), uses 270 GB per hour, so the same card lasts 27 min. The lightest 4K mode (30 Mbps) fits 9 hr.

GB per hour = bitrate in Mbps x 0.45. Card times use 95% of the labelled size (formatting and file overhead). Card speed: V30 up to 240 Mbps, V60 up to 480, V90 up to 720, CFexpress above that. * Sony's stated minimum for that format, which is stricter than the bitrate alone needs.

Slow motion

In slow motion the camera writes data faster than the file's bitrate, because each second you shoot plays back as several seconds. These figures are per minute of shooting, not of finished video.

Questions

How long does a 128 GB card last in the Sony A6700?

From 27 min in its heaviest mode to 16 hr in its lightest. In XAVC S 4K at 29.97p (4:2:2 10-bit, 140 Mbps) it holds about 1 hr 55 min. Times use Sony's published bitrates and 95% of the card's labelled size.

What memory card does the Sony A6700 need?

It records to SDXC (UHS-II). For its top mode (600 Mbps) you need a V90 card or faster; Sony lists SDXC V90 or higher. Lighter modes work with slower cards; the table on this page lists the card speed for every mode.

How much storage does an hour of 4K take on the Sony A6700?

Between 13.5 GB and 270 GB per hour, depending on the format and bitrate. XAVC S 4K at 29.97p (4:2:2 10-bit, 140 Mbps) uses 63 GB per hour.

Can the Sony A6700 record slow motion in camera?

Yes. Sony lists 105 slow-motion settings, up to 120 fps at 4K and 240 fps at 1080p. Slow motion writes more data per minute of shooting than the file's bitrate suggests, because each second you shoot becomes several seconds of video.

How we calculate: GB per hour = Mbps x 0.45. Card time = 95% of the card size / GB per hour. Real files can differ by a few percent (audio track, file overhead, card format).
