there is no reason the video should be this long, before you start working on longer things try shorter videos to work on velo/simple syncing and transitions
videos like these are so simple that i dont find a point in watching this and could instead go just watch replays unedited
i dont think the shader fits the music well, try listening to music and really think about what colors would match the tone/feeling it gives
these are all replays that come with toribash right? try going to the replay board to find more interesting replays, ive seen these done a million times before that its hard to debate which keyfaming angles are good or bad
honestly if you want to take my advice, scrap this. the entire length of the video with the speed is boring to watch and i dont think any type of effects/cc/whatever would help
also what program are you using
