Our freestyle ski team is looking to invest in a system that allows athletes to immediately review their competition ski runs with their coach after they get to the bottom. While they're playing back the video of their run, the camera will need to be available to shoot the next athlete. In an ideal world, a tethered camera would record directly and automatically to a folder on a laptop so that the athlete would be able to replay their run independently of the camera, leaving the camera free to keep recording the next athlete.
I've experimented with a Canon 5Dmk4 and the EOS Utility, which seems to automatically detect when the camera finishes shooting a video, and then prompts you the option of saving that file to your computer. This involves a lot of manual interaction, can take 30+ seconds to transfer a minute of footage, and ties up the camera during that transfer, preventing you from shooting the next skier if the transfer isn't completed in time. It's also a bit tedious and requires a coordinated effort between the videographer and the coach doing the video review.
We are hoping to invest in the GH5 due to it's slow motion capabilities, but am uncertain if this will pose new challenges (i.e. file sizes), or offer any solutions.
I'm familiar with the Ninja recording monitors being able to save to an SSD, but I'm curious of a solution that would allow me to instantly view recorded footage on a laptop, while leaving the camera free to shoot more video. I'm open to anything that would allow us to achieve what we're after as cheaply as possible!
