What is the difference between the trial version and the registered version?

The trial version and registered version are the same product, except for the limitations below:

1. Limit the output audio files to 3 minutes.

2. Add watermark to the output videos.

3. Only download 10 videos at most from sites other than YouTube. 

4.Could not convert 10 videos at most files with High Speed Conversion . 

After purchasing, you will get a registration code. Once you register the product, the free trial limitations will be removed. To remove the watermark in the output, you need to reconvert the source files with the full version.
