in thread 2d animation

The moving graph is composited on top of raw multi-camera footage, along with some other control information. This is in fact why I wanted to export the graph in a video format.

Hard to believe, yes, but sometimes the OP actually knows what they want. :-)

    The moving graph is composited on top of raw multi-camera footage, along with some other control information.

    That compositing could also be done at the client for a considerable saving.

    But it is your own and your clients cpu, bandwidth and time, therefore money, that you are spending. Not mine. Good luck.

      Do me a favor. Download six different ~8 hour h.264 38.8Mbps 29.97fps 1080p clips on your fastest laptop (yes, I'll wait). Fire up six instances of your fastest video player and tile them across your monitor. Mash play on all six at once. What's your frame rate user experience like?

      Now repeat the test with a single 6-7Mbps clip. (Pick one with a visible timecode if you're worried that lossy compression would render a graph illegible.)

      How did that work for you? :-)

        So, you're going to try and squash 230MB of 5760x2160 into a 7MB (what? 640x480) video overlain by a scrolling line trace. are you going to sync the 6 videos and line trace? You are going to need some CPU beef to do that in anything like real time.

        And you are going to have to plot that line trace as a mighty thick line to avoid it getting completely lost in the noise of the background.

        I still think that if the graph is worth displaying, that it would be better overlain at the destination than the source, but you'll find that out.

        Looks like you've got your work cut out for you. Best of luck.
