MP3 to MP4 Conversion FAQ

  • Why convert an audio file like MP3 to a video format like MP4?

    MP4 adds visuals to your audio so it’s discoverable and shareable on video-first platforms. Use it to upload music to YouTube with album art or waveforms, create simple social videos, add on-screen lyrics for karaoke or sing-alongs, turn podcast episodes into videos with cover images, or pair narration with a slideshow. Converting MP3 to MP4 turns audio-only content into engaging multimedia.

  • What visual options do I have when converting MP3 to MP4?

    Choose from: Static Image (album art or logo), Image Slideshow (multiple images with timed transitions), Text Overlay (lyrics, captions, or quotes), Waveform Visualization (animated audio waveform), and Reactive Effects (visuals that respond to beats and frequencies). You can mix elements-for example, a slideshow with a waveform and timed lyrics.

  • How do I add lyrics or timed text to my audio when converting to video?

    Use the built-in lyrics editor to sync text to the track. Import LRC files, paste plain text and tap to mark timings as the song plays, or try auto-sync to align lines automatically. Customize font, size, color, effects, and position. Unicode and right‑to‑left scripts are fully supported for accurate display across languages.

  • What resolution and quality settings should I choose for my audio-to-video conversion?

    For YouTube and most social platforms, 1080p with Standard quality balances clarity and size. Static visuals work well at 720p. For large displays or maximum detail, select 1440p or 4K. Bitrate is auto‑tuned based on resolution and visual complexity to ensure smooth playback without unnecessary file size.

  • Can I customize the aspect ratio or orientation of the resulting video?

    Yes. Pick 16:9 (widescreen), 1:1 (square), 9:16 (vertical for TikTok/Reels/Shorts), 4:3, 21:9, or set custom dimensions. Templates adapt to your choice so vertical and square videos fill the screen on mobile without black bars.
