Dayvid turns a song into a finished, publish-ready video (synced lyric captions, AI visuals, one-click upload) in a single shot. 🎬
The purpose is simple: I run a faceless channel publishing worship songs, and every single track meant hours of manual video editing before I could post it. I wanted to go from an audio file to a posted video without ever touching a timeline.
🤔 Why automate music videos?
Because the workflow was killing me. Cut the clip, sync the lyrics, add captions, render vertical, render widescreen, upload... every single week. It's the kind of repetitive work that makes you either quit or build a tool. I built a tool.
👤 Who's this for?
AI-music creators and faceless-channel folks: people generating tracks on Suno or Udio who want to ship them as video across YouTube, TikTok, and Reels without living inside a video editor.
🧐 How it works
You drop in a music file (or paste a Suno, Udio, or SoundCloud link) and a pipeline takes over:
- The audio gets transcribed into word-level timed lyrics, so captions land on the exact word instead of drifting a beat late.
- AI generates the visuals from the lyrics: a cover image, lyric-driven scenes, or real AI motion clips, plus your brand kit (logo, outro, fonts).
- Everything gets composed and rendered with Remotion, then you publish straight to YouTube, TikTok, or Instagram, or export the MP4.
From a raw track to something you can post in one shot. No timeline. No manual syncing. DONE.
🎧 Real songs, real reactions
I didn't want to trust my own demos. So I went to r/SunoAI and offered: "Drop your song, I'll make you a free video clip." 97 comments later, I'd run a pile of strangers' Suno tracks through Dayvid and posted the results back. No cherry-picking. Real songs, real people, unedited reactions:
"I'm not familiar with dayvid but it looks pretty impressive."
u/Islandboyo on r/SunoAI
"I think you captured it pretty well. I especially liked the flaring candles."
u/CodeNameFrumious on r/SunoAI
"Omg that was great dude, I loved it, thank you!"
u/SnowFun9310 on r/SunoAI
"Yes, the video fits the song very well. Thanks!"

🧑💻 The parts I'm most proud of
A few things under the hood I had fun building:
- Rendering moved off Vercel. A 40-minute video render laughs at a 5-minute serverless timeout. So renders run on Google Cloud Run, headless Chrome doing software WebGL, with Remotion driving every frame. Getting ProRes/MOV outros to not silently break Chromium was its own nightmare 😮💨.
- Word-level sync with a cache. Transcription is the expensive step, so it's cached by the audio's content hash. Re-upload the same song and it skips the paid transcribe entirely.
- It's agent-native. Dayvid ships a
SKILL.mdand a full public API, so you can literally send your AI agent to make and publish videos for you. "Send your agent to Dayvid" is a real sentence I get to say now 😂.
😤 The real hard part (it wasn't the AI)
The AI was the easy part. The grind was marketing and getting the publishing approved. To post to YouTube, TikTok, and Instagram you have to pass each platform's app review, and that process is a black box.
Google rejected me three times over twelve days. One rejection said my homepage "does not explain the purpose of your app." The real culprit? Framer Motion. My hero animated in from opacity: 0, so the automated crawler literally saw an invisible page and decided it was empty. I swapped the animation for plain CSS and suddenly my app had a purpose again 🙈.
Meta was worse. It bounced me twice with feedback so vague it was basically useless.
Days of work went into consent screens, privacy-policy wording, and screen recordings. Not code.
🌟 Try it
There's a free tier (300 credits, no card needed) so you can try it. Publishing straight to YouTube kicks in on the paid plans. Try Dayvid free and tell me what breaks. 🙂
