I use SeeMusic to render a 8 mins video like so:
The duration is 8mins & 9 secs. And here is the finished file, only 2mins and 13 secs

Especially, I have spent a half of a day to waiting for it render but the result make me unexpected. Pls fix this or I will use Synthesia Instead
The file seems to be rendering perfectly - here is the video I rendered using the settings you are using:
If Synthesia works better for you, by all means please use it for this!
Please include the following information so that I can look into this:
1. Tell me the Platform and Device in your post
( MacOS 10.14, MacBook Pro 3.1 GHz, 16 GB RAM )
2. Upload the Original Media Files used for your render to your post, including MIDI, Audio and Video.
If you prefer, you can email these to visualmusicdesign@gmail.com.
