Menu item details
Intra/Long GOP is a movie compression format. Intra compresses the movie by frame, and Long GOP compresses
multiple frames. Intra compression has better response and flexibility when editing, but Long GOP compression has
better compression efficiency.
Note
To play back XAVC HS 4K / XAVC HS 8K movies on a computer, you need a device or software with high processing capability
that supports the HEVC codec.
When recording 4K 120p/100p or 8K movies, [
Shooting] becomes disabled and locked to [Off].
If an APS-C size dedicated lens is attached, the edges of the screen may appear dark. When recording 4K 120p/100p or 8K
movies with this camera, we recommend using a lens compatible with the 35 mm full-frame format.
