Description
Generating a video from clips with the kenBurns model of width 720 fails in between when running on an AWS machine with sufficient memory.
Using xvfb-run -s '-screen 0 1024x768x24 -ac +extension GLX +render -noreset' node index.js fails with an out of memory error if the video is 720P in width.

Research direction
Reproduce the failure with the provided xvfb-run command, index.js, the kenBurns model, and a 720px-wide video made from about 200 clips. Investigate where memory grows during generation and verify that the same workload completes without the LLVM allocation error on the described AWS machine.
