    Why are exported mp4 files larger than original? LR export doesn't finish.

      Using LR 6.0, I tried to export 7 mp4 files. 

       

      Only 5 files exported before LR stopped exporting even though it still said "Export 7 files" in progress there's no disk activity.

       

      all sizes are in MB

       

      Original size     Exported size

      38.7                    54

      36.6                    51.7

      47.4                    67.2

      62.2                    87.3

      125.2                  172.8

       

      Video export settings were:

       

      Video format: H.264

      Quality: High

       

      Why does LR create larger files?   Quality won't be better than original.

       

      Why did export stop without error message?  I cancelled export after waiting 20 minutes for something to happen.
