AI Music Video Maker for TikTok
Create TikTok music videos in minutes using Flixly's AI suite. Generate tracks, animate with Seedance 2.0 and Kling 3.0, then lip-sync and export 15-second clips ready for upload.
TL;DR
Flixly combines music generation, image-to-video, and lip sync tools to produce 15-second TikTok clips. Run Seedance 2.0 or Kling 3.0 on 1080p references, add cloned vocals, and export H.264 files under 2 MB for quick platform uploads.
Flixly lets creators produce complete TikTok music videos without switching apps. Start by generating an original audio track, pair it with visuals from image-to-video pipelines, and finish with precise lip sync on 1080p exports.
Picking the right models for short clips
TikTok favors 15- to 30-second loops. Seedance 2.0 handles motion in under 8 seconds per clip while Kling 3.0 adds stable character movement across three-second frames. Veo 3.1 excels at background consistency when you feed it a single reference image.
Test Nano Banana Pro for quick thumbnail-style stills that become the first frame. These four models cover most TikTok needs when run at 24 fps and 9:16 ratio.
Model output specs

Building audio first
Open the Music Generation tool and enter a prompt such as "upbeat lo-fi beat with vinyl crackle, 90 bpm". Export a 15-second WAV file. If you need spoken lines, switch to Text to Speech with Gemini 3.1 Flash TTS at 48 kHz.
For custom artist voices, load a 30-second sample into Voice Cloning. The resulting track stays under 2 MB and fits TikTok upload limits exactly.
Turning audio into motion
Upload the track to Image to Video. Drop a 1024x1024 starting frame created in Text to Image with GPT-Image 2.0. Set duration to 15 seconds and motion strength to 0.7. The system returns a silent video that already matches the beat.
Add the original audio back in the editor. Run a second pass through Lip Sync Video if the clip contains a character speaking. This step takes roughly 45 seconds and consumes 5 credits.
Editing for the platform
Trim the final file to 15 seconds using the built-in cutter. Add auto-generated captions via the Shorts Generator so text appears on screen within 0.8 seconds of each lyric. Export at 1080x1920, 30 fps, H.264 codec.

Posting and testing
Upload the finished file directly from the dashboard. TikTok processes 1080p files in under 20 seconds. Track plays for the first hour; if retention drops after the 8-second mark, regenerate the opening frame with stronger motion in Seedance 2.0.
Creators who repeat this workflow five times per week report average view counts above 12 000 on new accounts. Adjust prompt length and credit spend based on your own results.
