Hey man really nice vid but a couple things the vid was smooth but the song didn't seem to sync up maybe thats just opinion but.
Also if you want to sync better you could also try syncing the song with the vid in after effects just another opinion.
And also lel try obs i mean its wahtever you like but obs seems to be easier to record TB keyframes with well atleast thats what i use and i like it better than fraps but obviously you don't have to try it if yah don't want to
