It is also an H.264 compression, but it is ALL-I (or Intra) meaning that each frame contains the full amount of color information and will be easier to playback and edit. It uses H.264 compression and offers lean data rates and plays well on a computer, however, it is a Long GOP codec and therefore is more difficult to edit without transcoding since color information is stored across multiple frames. XAVC S is the standard codec we’ve seen in Sony mirrorless cameras going back to the original A7S. The maximum frame rate of the Sony A7sIII is available in all codecs except for XAVC S-I, which is limited to 60p in both HD and 4K. Eight megabit equal one megabytes so you divide the data rate by 8 to determine how much storage space you need. Megabits are used to describe bandwidth (an internet connection, data transfer speeds, etc). Megabytes are used when referring to the size of a file or storage capacity. My head is already spinning with numbers and we haven’t even started talking about data rates.Īs a side note, I often find people get rather confused about the difference between megabytes (MB) and megabits (Mb/s). The A7SIII has 3 internal codec options that are available for almost every shooting mode (excluding high frame rate), frame rates from 23.976 to 119.88 in 4K, and up to 240 fps in HD! It can film in 10-bit 4:2:2, 10-bit 4:2:0, and 8-bit 4:2:0. It might not be exciting stuff, but it is definitely important to understand the bandwidth and storage requirements if you’re intended to purchase this amazing new camera.

You’ll need to purchase new CFast Express Type A media to take advantage of all that the A7S III has to offer, so understanding the speed requirements that are needed is crucial.įorget about the new sensor, external raw capabilities, and body design improvements, this is all about data rates. With the release of any new camera there is often a lot of confusion and misinformation about its capabilities, and since not that many people have gotten there hands on the amazing new Sony A7S III yet, Carl Yates from ProAV has taken the time to sit down and clear things up. In addition to its new AF modes, improved stabilization, and the inclusion of 10-bit 4:2:2 internal recording, it also offers a lot of different frame rates, fast recording options, and two completely new codecs. The Sony A7S III is packed with a host of new features and technological advancements.
