mpeg 4 speed and size

Hello,

I created the same video with about 45s in premiere elements 13 and cyberlink power director 13.

The codec in both cases is H264. The codes speed is 5 minutes in premiere and 1.5 minutes in director.

The resulting size is 80 MB (mkv) with director and 180 MB (mp4) in premiere.

The original (mov) video size was 114 MB.

For me this seems like premiere is doing something wrong. Both in speed and size.

But what? Is it modifiable?
