Set the render range in the output settings.
If you are just splitting up a video use Premiere Pro or The Adobe Media Encoder directly. You'll save a bunch of time. In AME you can set a custom duration for the three segments. In Premiere Pro just create three sequences and add them to the render cue. This is really basic stuff. You should study up.
I thought of a work around that I should have thought of days ago. It can even be done in windows movie maker it's that simple.
I will end up just splitting the original video clip and deleting the latter half of the video and saving the first clip and then reloading the original source file again and repeating the process with the following clip.
I can include a little bit of the previous episode in the following one that way as well. Tried rendering the full 52 minute video but it ended up stuck on 99% so just stopped and I will go about splitting it in the above mentioned way.
However, thanks for the comments both of you.
