Mysterious Post-Render Render, What Is It?

[Using Movie Studio Platinum 13, Toshiba Qosmio Laptop X775, Windows7 HP, Nvidia CUDA]  I record long events using a camcorder and various portable audio recorders.  Later I sync all the audio with the camcorder audio.  After everything is synced, I chop up the working file (.vf) into smaller segements on the time line marking them with Markers.  Then fade-ins and outs are applied.  When I render the output mp4, I use the "render-loop-region-only" option.  Which makes several smaller section output files (.mp4) from a MSP13 single working file (.vf).  Afer the render reaches the 100% point, the render does NOT stop, but continues on for 10 to 90 minutes (apparently depending on the rendered segment's length.)  If I render a working file completely not using the "render-loop-region-only" this does NOT happen.  While the post-render, render is happening a mysterious file with the same name as the rendered output file, but with the extra (.tmp) suffix appears.  After the render actually ends, this mysterious (.tmp) file disappears.  I use the Advanced-Options when rendering.

What is this mysterious post-render, render?  Is it necessary?  Do others also get this happening when they render?  Apparently I can just abort this post render by pressing cancel and I still get a working (.mp4) file.  But is this file corrupt or incomplete in some way?

These are my setting while rendering: HD 1080p; profile-Main; framerate-29.970 (NTSC); progressive scan; pixelaspect-1.000; numberofreferenceframes-2; variablebitrate-Max24,000,000-Av-12,000,000; numberofslices-4; use CUDA; audio-44.1khz.

I wonder if you are correctly setting the 'Loop Region'?  My understanding is that Markers do not perform this function.  Unfortunately the Help Screens are not helpful with explaining Loop Region (at least not in MS12 Platinum).  In MS12 the start and finish of a Loop Region is indicated by yellow triangles above the timeline not the orange marker boxes and lines. I don't know if it's the same with MS13.

Thank you very much for taking your time to reply.  I am aware of the yellow-triangles (it the same in MSP13) and that is what I use to set the loop-points.  The orange Markers do not have anything to do with loop-points.  I just use them because it helps me see the different regions in my partition of the video project.

chris, read this thread  for some previous discussion

Yes, this seems to be the same thing I am experiencing.  It doesn't stop the show, but sometimes the wait can be long, especially if the original render is long.  Mostly I just wait it out.  It is sort of comforting to know that this is just as much a myster to others as it is to me.  Is there a MSP13 "bug" list somewhere?

You'd need to scroll and read the posts/comments to find out what users may see as "bugs".

The SCS new versions/builds used to inform of the "notable (bug) fixes/changes" in their Release notes (which was also a readme folder and file with the program).
