Import edit Sony a7S III videos in Premiere Pro CC

When talking about the camera and which camera performs best according to their common uses, perhaps many photo shooting lovers have their own opinions. But there is no doubt that V is one of the best and the most popular cameras that have been pushed to the market.

The a7S III is the third model in Sony’s lineup of video-oriented mirrorless cameras, beginning with the original a7S in 2014 and the a7S II in 2015. The camera is capable of performing 4K internal recording with 10-bit depth and 4:2:2 color sampling when using either Long GOP or All Intra compression. And if you demand the ultimate quality, the camera will output 16-bit raw over HDMI, which can be saved as 12-bit Log ProRes Raw by a recorder like an Atomos Ninja V.
