I'm using the 1.4 beta of Fusion Studio desktop for Windows (220.127.116.112 [a5ab95fc]). I'm running on a Windows 10 Home system with an Intel Core i7-6700K CPU @ 4.01 GHz, 32 GB RAM, an NVIDIA GeForce GTX 1070, a SSHD system drive plus an eSATA 2 GB hard drive. I've got at least 50 GB of disk space on the SSHD system drive, plus more than 1 TB on the hard drive.
When I try to render a 7 minute video from my Fusion on my desktop it gets to about 30% done, memory is fully consumed, and then it crashes (exits without any dialog or warning... I don't get any errors from Windows either). I've watched system resource usage using the Task Manager during a render. I can only render if I break a long video up into sub-2:30 minute clips. Then, memory is consumed to about the 90% mark during the rendering/stitching of each clip, then it is released before the next clip gets stitched. I can also see that the rendering output is consuming 100% of the capability of the destination drive (my source is on SSHD, my output is on the eSATA). Rendering seems to take about a second for every 2.5 seconds of video (5.2K/30 FPS down to 4K).
I don't understand the software design decision behind holding all of the video information in memory while stitching instead of reading in, say, 30 seconds at a time, stitching it, storing it in a temp file on the drive, repeating until all of the video has been stitched, and then assembling the final video from the temp files. That would take a lot less memory and because of the lack of thrashing due to VM page swaps and the lack of the constraint of the output drive the performance should be a lot better.
Shouldn't I be able to readily render/stitch any video I capture on the Fusion with my system?
I love the promise of the Fusion, but the software needs some rearchitecting if it is going to live up to the hardware. Unless I'm doing something wrong, that is.

Please add default user preferences for rendering? (Or at least remember my previous selections) It becomes pretty old having to constantsly change the default from Cineform to ProRes in my case. (Even though I can select all files at once)
Does the Fusion or Fusion Studio not know what level is? I always thought the gyropscope information from camera should tell Studio how to level? Can an auto horizon button feature be added to the Studio app?
How about a file transfer feature? That is: transfer-import contents of both memory cards properly into folder for later rendering and stitching? (I know I can do it manually--- but seeing if there is a more elegant way.)
