SUMMARY
First time using kdenlive, portable version on Windows 10. Made a short video and selected Render from the Project menu - MP4/H264 format.
It seemed to get all the way through, but right at the end it gave the error - 
"Rendering of C:/Users/username/Videos/test-video-1.mp4 crashed
[mp4 @ 00000262e75db800] Timestamps are unset in a packet for stream 1. This is deprecated and will stop working in the future. Fix your code to set the timestamps properly [mp4 @ 00000262e75db800] Encoder did not produce proper pts, making some up."

From which drive do you run Kdenlive portable?
Do you have a typewriter effect in a title clip?
