Rendering is what happens when you press ENTER while working in the timeline, so PPro will create temporary files for smoother timeline playback
Is that what you mean... or do you mean to export some or all of your project video to a new file?

I'm offended you'd even ask such a question.
and no I'm not in the exporting stage just yet.
The few video files I'm working on is a bit weird and what I did with the settings to record them will never be used like that again due to causing difficulties to everything else but I won't get into that right now.
To sum it up, these specific videos I'm working on at the moment will not play through the sequence properly unless I render beforehand.
Proof of success was shown in my 1st half of the video.
I rendered the video file as in 'RENDERING PREVIEW', and it worked just as it should.
But it wouldn't work in the 2nd half of the video for some reason and that is the part that confuses me alot despite the problem being somewhat minor.
I hope that answered your question? haha..
List the specs of the media and the sequence settings.
