  I haven't used it myself but judging from the 9th picture it appears to have the concat functionality built into the GUI.

Body: <p>I had a 595mb .MP4 video (data rate: 510 kbps, Total bitrate 638 kbps). And I joined it with another .MP4 youtube video with a lower quality(only the end part).. The resulting video file has a data rate of 389kbps and Total bitrate of 517 kbps.. The size is also significantly smaller; 494mb.. I used a program called Video Combiner.. And side by side I can see the original one is better quality looking.. so what am i doing wrong? any suggestions? I just wanna join 2 video files without loss of total quality.</p>

  Your program probably re-encoded the resulting video file from scratch and used whatever setting it considered okay.
  
  If you want to have more control about the process *and/or* do not want it to re-encode the video at all (if both are of the same format), then I strongly suggest looking into ffmpeg for this.
  
  For reference, <https://trac.ffmpeg.org/wiki/Concatenate> - the concat demuxer is what you want.
  
  As the most simple example, copy both your video files (let's call them videoA.mp4 and videoB.mp4) into the same folder. Create a videos.txt file with just this content:
  
  ```
  file videoA.mp4
  file videoB.mp4
  
  ```
  
  Now run ffmpeg with this command:
  
  ```
  ffmpeg -f concat -i videos.txt -c copy videoOut.mp4
  
  ```
  
  If all goes well this gives you a new file with both videos in one file, with the original encoding intact.
