How to set the output quality higher?

There are two tips for you to output higher quality.

1. If your original video is high definition, you'd better choose output format as HD formats. After you load the video into the program, go to the top menu, choose Export> Exporting to Device, in Format tab, you can choose HD MP4.

2. If your original video is not high definition, please adjust the resolution and bit rate higher to have a try. However, to keep the quality of the original file, please be sure to set the parameters not higher than that of the original one. If you want to improve the parameters, for instance, set the resolution higher, then you should set the bit rate higher accordingly.
