The Studio 4K Pro records video with 10-bit 4:2:2 color using either ProRes or DNxHD codecs, as well as the H.264 and H.265 compression formats. With two SSD slots and two SD card slots, you can record almost endlessly as one SSD becomes full, recording automatically continues on to the other, and the SD card slots are also hot-swappable. The Studio 4K Pro features one 12G-SDI input, two 12G-SDI outputs, a loop-through 12G-SDI output, a dedicated SDI monitor output, and there's also one HDMI input and one HDMI output that can all output up to DCI 4K. The 4K Pro can even play ProRes 4444 files in true UHD for fill and key outputs. The ports autodetect the signal and will adjust to the SD, HD, 6G-SDI, or 12G-SDI format input. The 3-pin XLR timecode input and output allow you to sync timecode with other devices, and it also allows you to daisy-chain with other devices to create a timecode sync chain.
