Frequently Asked Questions
What is an AI onbeat effect music video?
An AI onbeat effect music video is a short formatted clip where the visuals automatically sync to the musical peaks of a track. The AI first analyzes the song’s BPM, beat grid, kick and snare onsets, and per-beat energy envelope. Then it ranks every candidate effect timestamp using energy match, onset clarity, and temporal preference. Finally it places effects, transitions, and camera moves exactly on the downbeats and drops. For me, this means I skip the most tedious part of editing: manually aligning cuts to the waveform. The result is a viral-ready clip that feels rhythm-locked, with no manual beat-matching.
How accurate is the beat sync really?
It uses two-stage BPM detection: a client-side metadata read plus a backend CNN recalibration, then maps a frame-accurate timestamp array for every beat. Onset detection logs kicks, snares, hi-hats, and claps with time, type, and strength data. The energy envelope tracks per-beat RMS loudness so the system knows exactly where the song peaks and dips. It also segments Intro, Verse, Chorus, Bridge, and Outro with tags like energy level and dominant instruments. Then a 5-tier beat-cycle quantization sets the pacing: 4-beat tight cuts for high-energy choruses all the way up to 64-beat sustained outro scenes. So yes, it is precise enough to build an entire full-length video on the same sync grid.
Can I use onbeat effects for a full song, or only short clips?
You can do both in the same project. Each project outputs short-form viral clips such as 15-second TikTok cuts and a long-form full MV up to roughly six minutes. The onbeat effect library is optimized for 60-second-class short clips, but the same music-aware engine powers the full MV pipeline with Automatic Mode. You choose a creation lane: Singing MV, Storytelling, Abstract, Realtime, Onbeat Effect, and more. The effect templates are auto-aligned to song peaks, whether the track is 30 seconds or three minutes. That is why I usually generate one project and use the clips for socials and the long-form version for YouTube.
Can I use my own songs from Suno, Udio, YouTube, or SoundCloud?
Yes. Freebeat accepts a paste link directly from Suno, Udio, YouTube, SoundCloud, TikTok, and Spotify via OAuth. You can also upload local MP3, WAV, M4A, or MP4 files. Once the audio is in, the AI reads the BPM and structure before any video is generated. This is perfect for a workflow when you have just finished a Suno track and want a music video immediately. The same engine keeps the visuals locked to the uploaded master, not a stock version of the song.
What aspect ratios and resolutions are supported for viral clips?
Every project can output four aspect ratios in one pass with auto-repositioning: 16:9 at 1280x720, 9:16 at 1080x1920, 1:1 at 1080x1080, and 4:5 at 1080x1350. Export is MP4 with H.264 and AAC, so there is no transcoding needed for TikTok, Reels, Shorts, X, Bilibili, or Weixin Channels. Resolutions go up to HD 720p and Full HD 1080p depending on your plan. Also, audio is normalized to LUFS -14 so platforms like YouTube or TikTok won’t recompress and degrade the loudness. That makes the clip sound exactly as loud as the reference tracks on those platforms.
How much does it cost to make viral onbeat clips?
There is a free plan with 500 lifetime credits, a 30-second duration cap, 720p output, and a watermark. Paid plans start at Basic at $4.99 per week with 1,990 weekly credits and no watermark, while Standard is $9.99 per month. For more volume, Pro is $26.99 per month with 10,000 credits, a six-minute cap, and 1080p output. There are also Ultimate and Creator tiers, plus pay-as-you-go Boost Packs starting around $0.0040 per credit. For a 15-second viral clip, credit usage depends on the model — for example, many modern video models run 20 to 84 credits per second depending on resolution and audio. I typically start with the free plan to test effects, then buy credits only when I am ready to publish without a watermark. This is why so many independent musicians and content creators now default to freebeat for release visuals.
