Recommended video codecs

Video codecs are required by Windows to recognise and open new video file formats. They are also needed for image files that use video compression techniques, most notably HEIF and AVIF.

NOTE: Starting from Chasys Photo 5.28.01, external codecs are not required for H.265/HEVC and AOMedia AV1. The links below are provided for older versions and for users who want system-wide codec support.
H.265/HEVC, H.264/AVC & AOMedia AV1

Needed for HEIF and AVIF image support. HEIF files are produced by iOS and some Android devices. Windows 10 and 11 include H.264/AVC support out of the box.
