Key facts

Recording media: SD (UHS-II), dual slots
Published recording modes: 61 normal
Highest bitrate: 645 Mbps: Cinema RAW Light LT (CRM) at 59.94p (RAW 12-bit)
Lightest 4K mode: 100 Mbps: MP4 H.265/HEVC YCC420 10-bit Long GOP at 29.97p / 25p / 24p / 23.98p (4:2:0 10-bit)
Card for the top mode: V90
128 GB card at 4K 30p: 1 hr 41 min in XF-AVC (MXF) H.264 YCC422 10-bit Long GOP at 29.97p (4:2:2 10-bit, 160 Mbps)
Top frame rate (normal video): 59.94p at DCI 4K, 4K, 2K, 1080p and 720p
Slow motion (in camera): Not published by Canon

"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 41 min of XF-AVC (MXF) H.264 YCC422 10-bit Long GOP at 29.97p (4:2:2 10-bit, 160 Mbps) on the Canon EOS C70. The heaviest mode, Cinema RAW Light LT (CRM) at 59.94p (RAW 12-bit, 645 Mbps), uses 290 GB per hour, so the same card lasts 25 min. The lightest 4K mode (100 Mbps) fits 2 hr 42 min.

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. * Canon's stated minimum for that format, which is stricter than the bitrate alone needs.

Questions

How long does a 128 GB card last in the Canon EOS C70?

From 25 min in its heaviest mode to 22 hr in its lightest. In XF-AVC (MXF) H.264 YCC422 10-bit Long GOP at 29.97p (4:2:2 10-bit, 160 Mbps) it holds about 1 hr 41 min. Times use Canon's published bitrates and 95% of the card's labelled size.

What memory card does the Canon EOS C70 need?

It records to SD (UHS-II), dual slots. For its top mode (645 Mbps) you need a V90 card or faster. 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 Canon EOS C70?

Between 45 GB and 290 GB per hour, depending on the format and bitrate. XF-AVC (MXF) H.264 YCC422 10-bit Long GOP at 29.97p (4:2:2 10-bit, 160 Mbps) uses 72 GB per hour.

Can the Canon EOS C70 record slow motion in camera?

Canon does not publish an in-camera slow-motion mode for the Canon EOS C70.

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).
