I moved my set of SendTo_FFmpeg batches to a Github repo. So if you have issues, ideas, request, you can post them there.
There's also new AEExprTool I develop for myself. It's After Effects script for adding/removing error handling code to AE expressions in bulk. It's already a huge time saver for me. Would love to have some feedback cause I plan to make it a reliable full featured tool one day.
