What SD-card speed and capacity for video do I need?

Published Reviewed Skip to comparison

People matching a card to a camera’s video bitrate and recording time. The decision this page isolates is narrow on purpose: estimate file size and a video speed class from bitrate and minutes. Subject distance and weather sealing are planning facts. A body name is not a kit.

Recording load

Video Speed Class to compare

V30

88 GB estimated file size

Compare cards with at least:

  • At least 88 GB of free card capacity
  • Video Speed Class V30 or faster
  • Confirm the camera manual; a class mark is a minimum sustained write rating, not a guarantee for every codec

What to verify before you buy

How this estimate works

Convert bitrate × time into gigabytes, then map bitrate to the SD Association Video Speed Class that covers that sustained write rate.

Know the limits

  • Camera manuals override the planning class when a codec or bus needs more.
  • Peak bitrate can exceed the average bitrate used here.
  • A class mark is a minimum sustained write rating, not a brand ranking.

Frequently asked questions

How does the sd card video work?

It converts the published inputs on this page into a planning class using a published rule. Convert bitrate × time into gigabytes, then map bitrate to the SD Association Video Speed Class that covers that sustained write rate. The headline is a class such as v30, v60, and v90, not a vendor ranking.

Is SanDisk Extreme PRO SDXC V30 better than Sony TOUGH SF-M V60?

This page does not rank SanDisk Extreme PRO SDXC V30, Sony TOUGH SF-M V60, and Lexar Professional 2000x V90. SanDisk Extreme PRO SDXC V30 and Sony TOUGH SF-M V60 are listed because they are real products with official pages that map to different or overlapping classes. The useful question is which class matches your inputs.

Do the product links earn Decision Lantern a commission?

Yes, when a product name or “View on Amazon” link goes to Amazon. Those are associate links. Decision Lantern may earn a commission at no extra cost to you. Official manufacturer pages are separate and are not tagged.
