Apply the same effects to the two separate clips and you can join them together in any non linear editing program. There are free programs like iMovie or Splice that you can get even get on a mobile devise. Or professional programs such as Final Cut Pro or Adobe Premiere Pro.
You could alternatively not apply any effects to the two clips, but add them into your editing software and do all effects there. Upon exporting they will be combined into one video.
