Video frame freezes

I have a basic project that has a moviefilein top and a moviefileout top. The issue is that a certain frame (randomly) shows up for a fraction of a second making the output video freeze on that frame. Doing some tests, the index of the input video briefly pauses and gets encoded in the output video. Other effects or a timeline index keeps going through the pause. I am not sure if there are some settings I can play with to make this behavior stop. I am not using real time rendering which might have skipping freeze frames. Any help on this would be greatly appreciated. Here is a sample file Dropbox - File Deleted
The freeze happens at 16s at index 304

I assume your application is pausing while it’s encoding, causing this to occur. Have you tried with the real-time flag off, to ensure it processes every frame?
