Questions About 2D Lip Sync Studio

2D Lip Sync Studio is a focused tool for creating and editing mouth timing for 2D character animation. It helps you synchronize spoken dialogue with a set of mouth shapes without the complexity of a full animation suite.

Import your dialogue audio, enter the words exactly as they are spoken, and sync the audio. 2D Lip Sync Studio aligns the dialogue with speech sounds and creates corresponding mouth changes. You can then review the results and adjust the timing before exporting.

No. 2D Lip Sync Studio is designed specifically for lip sync. It creates and helps you edit the mouth timing for your character, but it does not replace your illustration or animation software.

2D Lip Sync Studio is currently available for Windows.

2D Lip Sync Studio supports WAV, MP3, and M4A audio files. Clear dialogue with minimal background noise will generally make the spoken words easier to work with.

2D Lip Sync Studio currently supports audio files up to 10 minutes or 250 MB. For the easiest workflow, shorter dialogue clips of about 5 minutes or less are recommended.

Yes. Paste or type the dialogue exactly as it is spoken in the recording. The transcript helps 2D Lip Sync Studio align the spoken words, sounds, and mouth changes.

If you change the transcript after the audio has been synchronized, you may need to sync the audio again so the words, sounds, and mouth timing remain aligned.

Yes. You can import a character image into the Preview area, position it, and place the animated mouth over your character while you work.

Yes. All 12 mouth positions can be replaced with your own custom PNG artwork so the lip sync matches the style of your character.

No. The mouth images in 2D Lip Sync Studio can be used as a visual reference while you review and edit the lip sync. If your character already has mouth shapes in your animation software, you can keep using them.

When you're finished editing, export the lip-sync timing data as TXT or DAT and use that data with the mouth shapes already in your animation project. You only need to export mouth images if that suits your particular workflow.

2D Lip Sync Studio uses 12 mouth positions:

• Rest / Silence
• A / I
• E
• O
• U / OO
• F / V
• L
• M / P / B
• TH
• CH / J / SH
• R
• S / Z

No. You can create mouth artwork that matches your own character and animation style. The important thing is that your mouth images are prepared consistently so they align correctly when switched during playback.

Yes. The generated lip sync is editable. You can review the Dialogue & Mouth Timeline and insert, change, or delete mouth changes when you want more control.

Yes. The unified timeline controls allow you to navigate through frames and mouth changes so you can inspect and fine-tune the timing.

Yes. Words in the dialogue timeline can be used to navigate the recording, making it easier to review specific parts of the dialogue.

2D Lip Sync Studio provides several export options so you can choose the format that fits your animation workflow:

• Generic Mouth Changes (.TXT)
• PNG Sequence (.ZIP)
• Moho / Papagayo / OpenToonz / Tahoma2D (.DAT)
• Toon Boom Harmony Script (.JS)
• Adobe Animate Script (.JSFL)
• MP4 Preview (With Audio)
• Transparent WebM (With Audio)
• Captions / Subtitles (.SRT)
• WebVTT Captions (.VTT)

This means you don't have to export mouth images unless that's the workflow you want. You can export timing data or scripts for supported animation workflows, video previews, image sequences, or caption files.

You can export the lip-sync timing data as TXT or DAT and use that timing with the mouth shapes already in your animation project. This lets you keep your character's existing artwork and rig in your animation software rather than replacing it with exported mouth images.

If your workflow does use image sequences, 2D Lip Sync Studio can also export numbered PNG mouth images. PNG export is an option, not a requirement.

No. The word and phoneme alignment used by 2D Lip Sync Studio runs locally on your computer. Your dialogue does not need to be sent to a third-party speech-processing service just to generate the lip sync.

2D Lip Sync Studio is designed around a focused workflow rather than a large collection of animation tools. The basic process is:

Import → Sync → Review → Adjust → Export
