Sorry, but I was bit busy.
Here are some files:
https://drive.google.com/file/d/0B5S...ew?usp=sharing
they have descriptions in the name. Main file is 10 seconds as is. Then there is one which has first 2 sec edited out, last 2 seconds edited out and 2-5sec edited out. If you open them in QT player you will see everything as they have TC and frames burned in.
Latest ffmpeg respects editing, few weeks old won't.
