A high-speed chase on a highway or a moment of quiet reflection atop a skyscraper overlooking the city.
Common in Metal Gear Solid or Shonen Anime edits, this relies on high-impact transitions and dramatic dialogue.
A fading out to static, leaving the viewer with a sense of "mono no aware" (the pathos of things).
Low-quality VHS grain over scenes of a Japanese summer—train stations, cicadas, and vending machines.
Start with a "glitchy" intro showing the character at their peak.
If you're struggling with structure, try exporting stills from your video or using a subtitle file (.srt) to find the "beats" of the story before you start cutting.
Which are you using for the edit? I can give you more specific scene-by-scene beats if I know the source material.
