Product Demo Explainer Video Edit

I'm looking for a SaaS video editor to make a few updates to an existing product explainer video. The video is already complete, and I'll provide the raw project files and any required assets.

Scope of work:
- Update text, visuals, or timing as instructed.
- Make minor edits while maintaining the existing style and quality.
- Export the revised video in 1080p MP4.
- Return the updated project files.

Acceptance criteria:

- All requested changes are implemented accurately.
-Existing animations and transitions remain smooth.
- Final video is delivered in 1080p.

Scope is limited to up to 3 minor revisions.

If you've worked on SaaS product demos or explainer videos, please include a few relevant samples with your proposal.
