- Supports 4 different video file formats (XAVC HS 4K, XAVC S-I 4K, XAVC S 4K, XAVC S HD)[14]
- Dual SD Card Slots,[15][16] CFExpress Type A Slot (only SLOT 1)
Dual memory card slots of the right side of the Sony α7 IV, the camera supports the operation while both card slots are occupied, both card slots supports UHS-I and UHS-II class SD cards 1CFexpress Type A & SD card slot 2SD only slot Dynamic Range and Color Independent Testing
Independent testing by Gerald Undone using Imatest software and a Xyla color range chart demonstrates a dynamic range of 12.8 stops of light, which is approximately 1/3 of a stop better than the Sony A7s iii and approximately the same as the Sony a1.[17] It color matches fairly well with the Sony A7s iii and Sony a1, with the Sony A7s iii leaning a bit green, the Sony a1 a bit magenta, and this camera between the two (tested using DCS Labs -SW – CDM 28R – v15.2 A3 color chart) and with individual white balancing, the colors are very similar.[17]
Video formats
Camera is using in house developed AVC Video Format called XAVC. The format is compressed format achieving balanced quality and file size. Recording in color depth of 10-bits and 4:2:2 chroma subsampling is possible with Sony’s XAVC codec.
- All Intra-frame system that compresses each frame individually to achieve best quality.
- When recording 4K movies in the XAVC HS format is an optional which is using a HEVC codec (H.265) and has high compression efficiency.
- The camera can record movies with higher image quality than XAVC S movies but the same data volume.
- Camera can record in “Long GOP” codec (H.264) compression which is compressing multiple frames to reduce file size.
