Discovered the Insert Slide Show feature but find that if I add more than about 400 pictures it doesn't know what to do with it, and in fact just kind of locks up on me. I found I had to do it in smaller batches, render the video, then combine multiple videos, then add the audio I wanted.
Is there a limitation how many pictures I can include in a batch.
I have no other issues with editing and rendering large video files, this seems like a SW limitation.
