From trial download page:
Other limitations:
Watermark appears on the video
Limited templates and effects
Importing and producing H.264 video files is only supported on
Windows 10/8.1/7 SP1 systems or hardware platforms offering independent
H.264 encoding and decoding
2K/4K resolution H.264 video files are not supported
Importing and producing H.265 video files is not available
Importing and producing Dolby or DTS 5.1ch audio files are not available
So what use is a 30 day trial if it won't allow you to evaluate? Watermarking the output should be enough to stop people from using it for free, no??
