Googled for a couple of hours, found a plethora of semi-conflicting information, and am still not much clearer on what ffmpeg commandline switches to use to convert (re-encode) a 4K HDR webm video, eg vp9. This is the video player which is able to use BlackMagic DeckLink extension cards as a target (output) device (I use Intensity Pro PCI-E card) Optionally you can use it like full screen video player. For example, if there are two succesive frames shown at timestamps 1 and 2, and you want to speed up the video, those timestamps need to become 0. These are the FOURCCs I know about that refer to compressed formats (the ones that you see displayed when you don't have the right codec installed to play a given AVI file). Working on a shot with very noisy input. ts Not certainly sure about how ffmpeg works but. I can also confirm FFmpeg can 'talk to the DeckLink and set the right mode, I can confirm a picture 'flows' through the card as I can see it showing up on the output loop on my monitor, as soon as I put any of the FFmpeg commands in, however, FFmpeg does not start encoding/capturing.
