here's a video i shot at <> 3400*1700, and there is a single frame "glitch" at about 7 or 8 minutes from mlvfs. using separate card readers for each card definitely helped, but it is still not perfect. this "bad frame" happened repeatedly, no matter how many times i rendered, and also across reboots of the pc.
the strange thing is that the frame is correct when scrubbing in resolve, but rendering always results in the error.
this setup is so precarious that it isn't surprising there are such issues. it's a real drag, because it is such an amazing timesaver when it is working...
i may try different versions of dokan again to see if there's a "solution" but it may be related to so many other factors, including the peculiarities of this particular build of windows, or card reader drivers, or quantum effects due to the sun's corona, etc.
i was considering rendering the single frame as a tiff and then surgically inserting it, but even rendering as tiff resulted in the error!
