Hey, I am thinking about buying this product, however I tried the free version first. It is amazing and would really save me a lot of time. I have inserted my video that has an audio which I plan to use like in the tutorial. The midi file I used is a bit shorter than the video so I had to adjust the time to -23 in the video settings until it was aligned.
When I finished the project, the sound, video and midi (falling notes) matched in timing and I pressed render. It rendered unexpectedly fast and I opened the finished file. The keyboard video was all messed up, ie started way too late (after the notes were already falling). The sound started even later, after over 50 seconds had passed. The video of my keyboard also played for 40 seconds until it reset to the begging of the keyboard video which was a bit confusing as well.
