I decided to try the memory leak tool valgrind.  It reported what seemed to be many memory leaks.  I wonder if some of those are false leaks.
Here is the command that I ran:
valgrind --tool=memcheck --trace-children=yes --error-limit=no --leak-check=full ./openshot | tee debug
Here is a summary of the final report:
==622== LEAK SUMMARY:
==622==    definitely lost: 40,640 bytes in 82 blocks
==622==    indirectly lost: 57,858 bytes in 1,797 blocks
==622==      possibly lost: 619,101,321 bytes in 86,111 blocks
==622==    still reachable: 476,260,399 bytes in 95,483 blocks
==622==         suppressed: 0 bytes in 0 blocks
==622== Reachable blocks (those to which a pointer was found) are not shown.
==622== To see them, rerun with: --leak-check=full --show-reachable=yes
==622== 
==622== For counts of detected and suppressed errors, rerun with: -v
==622== Use --track-origins=yes to see where uninitialised values come from
==622== ERROR SUMMARY: 186054124 errors from 5088 contexts (suppressed: 0 from 0)
My debug file is basically empty so I ,perhaps, should have run it with >&

Here are a few final lines. I will have to rerun it.  It crashed before rendering was complete.
==622== 96,468,992 bytes in 23 blocks are possibly lost in loss record 20,865 of 20,867
