10-Second YouTube Intro

The intro must run exactly 10 seconds and put my channel name front and center in a purple-themed, text-driven animation, if possible maybe start with my name this switch it to my twitch name. Behind it I want a calm, cool rap-style beat that is 100 % royalty-free so I never face copyright claims on YouTube. Feel free to add subtle motion graphics or light effects, but keep the focus on the name and the vibe smooth rather than hyper-energetic. I have an audio clip I want added to the intro also

Deliverables
• 1920 × 1080 MP4 (10 s) with audio embedded
• Separate audio file plus proof of its free-to-use license
• Editable project file (After Effects, Premiere Pro, or similar) so I can swap text later

Acceptance criteria: the video length clocks in at 10.0 ± 0.2 s, the purple palette is clearly visible, audio passes YouTube copyright check, and the final render is clean and artifact-free.
