Brat Video Audio Sync & Supported Formats

How audio timing works in the Brat Lyrics Video Generator, which file formats are safest, how to trim audio, and what to try when decoding or sync goes wrong.

Choose a Browser-Friendly Audio Format

The Brat Lyrics Video Generator accepts MP3, WAV, M4A, AAC and OGG, but the browser still has to decode the actual codec. MP3 and WAV are the safest first tests when you want to rule out format problems quickly.

Understand Line Timing and Duration

Create Sets from Lyrics turns each non-empty line into a timed segment. You can now give each line a different duration, so a hook can stay longer while a short transition moves faster.

Trim the Part of the Audio You Need

After loading a track, use the audio start and end controls to select the part of the file you actually want. This keeps short clips focused and avoids rendering a long unused intro or outro.

Sync Text More Deliberately

Use line duration as a relative timing map: longer values receive more of the final clip, shorter values move faster. Preview the order first, then adjust the durations around the phrases that need more reading time.

If exact beat-level editing is your goal, start with the strongest phrase breaks and trim the audio to the section you want before fine-tuning individual line durations.

Fix Decoding and Sync Problems

  • Try MP3 or WAV if the audio file is accepted but fails to decode.
  • Shorten the trim range when a long export is heavy for the browser.
  • Reduce FPS before changing the text if export performance is the problem.
  • Remember that GIF and PNG frame exports are intentionally silent.

A Practical Audio-Sync Workflow

  1. Paste short lyric lines. Use natural phrase breaks.
  2. Create the timing sets. Give important lines more duration.
  3. Upload audio. Prefer MP3 or WAV for a compatibility-first test.
  4. Trim the useful section. Set start and end before the final render.
  5. Preview and export at 24–30 FPS. Increase FPS only if the motion benefits.

FAQ

Frequently Asked Questions

Quick answers about supported audio formats, trimming, line timing and browser compatibility.

Which audio format should I try first?

MP3 or WAV is the safest compatibility-first choice. M4A, AAC and OGG can work, but decoding support depends on the browser and codec.

Can I trim audio inside the video tool?

Yes. After loading audio, use the start and end controls to choose the part of the track you want to render.

Can I change how long each lyric line stays on screen?

Yes. Create the text sets, then edit the duration for each line in the timing panel. The tool uses those durations as relative timing weights across the rendered clip.

Why can audio be accepted but fail during export?

The file picker can accept a format that your browser cannot decode. Try MP3 or WAV, or convert the same source audio to another codec.

Do GIF and PNG frames include sound?

No. Audio is only relevant to the video export path; GIF and PNG-frame exports are silent.
