Use Blender 2.79 to create video file

Use Blender software 2.79. I will send you a link to a “.blend” file, 5 video files, and one audio file. Open the blender file in which I have arranged the audio and video files, plus I specified the number of frames which corresponds to the length of the video file. Then using your expertise, you adjust the settings. This part I could not figure out myself. When I rendered it the audio would be out of sync and the video would appear too fast, but it looked perfect when previewing in Blender. Note the length of the file is set so part of the last video file is excluded and that is okay. Please render the video in mp4 or mkv format. Make a note of any changes you had to make and check the rendered file plays properly. Save the new Blender file with these settings as "[login to view URL]" and send it to me. I want to drop it into my folder, open it, and render it myself. Tell me what setting changes you made and if you had to do anything other than chose "render animation" from the render menu to create the video. As soon as I am able to create the video file and verify it plays properly you are done. Thanks.
