Animation tutorial
To learn how to make lip sync in blender, start with the character you actually have: a 3D face with movable geometry or 2D art with separate mouth drawings. Both paths depend on clear audio, deliberate mouth poses, and a final timing check. This guide covers the animation work you do in Blender; the video prompt below is a separate way to explore a speaking-character concept.
Partner workflow: Vidione creates paid talking-avatar video from a photo, script and voice, or a single AI video shot after sign-in and subscription. It cannot change the speech or lip movements in an already recorded video. These links transfer no footage or prompt.
Vidione generates a talking avatar from a photo, script and voice after sign-in and subscription; it does not re-dub existing video. This guide transfers no footage or prompt.
Choose the route by how the mouth is built, not by the style of the finished video. A recorded voice line gives either route a timing reference.
Follow a broader production workflow when your footage, audio, and final edit matter more than character rigging.
Use a performance-focused rehearsal guide when you are matching your own face to a recorded voice.
Compare animated-mouth approaches before committing to a 3D rig or a set of 2D drawings.
On a mesh with usable mouth topology, make a neutral Basis shape key and a small set of distinct speaking poses. Keyframe their Value sliders against the voice recording.
You already have a facial mesh, but its mouth is still neutral in every shot. Add shape keys for closed lips, an open vowel, a wide vowel, and a rounded mouth; test each pose for stretched geometry.
The face has reusable controls for a short lip sync performance rather than a separate mesh for every sound.
how to create a lip sync videoYou have a finished voice line and need readable dialogue in a medium shot. Place the audio on the timeline, listen in short segments, and keyframe mouth changes near the audible consonants and vowel peaks.
The lip sync follows the recording without requiring a unique mouth pose for every letter.
how to create a lip sync videoYou want the animated delivery to feel less mechanical. Say the line aloud first, noticing where the jaw pauses, where the lips close, and where the character takes a breath.
Your timing choices reflect a performance, not just a sequence of phoneme labels.
how to practice lip sync for interviewYou are recording your own guide voice for a stylized avatar. Keep the spoken line short while establishing the rig, then review the audio and mouth movement at normal playback speed.
You can correct obvious lip sync drift before animating longer scenes.
how to practice lip sync for interviewIf your character is drawn rather than modeled, prepare a few mouth images with a consistent position and scale. Change the visible drawing as the audio plays.
Draw a closed mouth, a relaxed open mouth, a wide vowel, and a rounded shape. Keep the chin and mouth corners aligned between drawings so a swap reads as speech rather than a jumping face. Import them into your chosen 2D setup in Blender and confirm that only the intended mouth is visible.
Add the recorded line to the editing timeline and listen to it repeatedly. Mark strong syllables, lip closures, and brief silences. For lip sync, prioritize the sounds a viewer can see: closed lips for sounds such as M, B, and P, followed by a clear opening on the next vowel.
Keyframe visibility or switch drawing frames at the marked beats, according to how your 2D character is assembled. Preview at normal speed rather than judging isolated frames. Hold a pose through a short vowel when it reads well, and return to a resting mouth during pauses instead of cycling constantly.
Neither method creates convincing dialogue by itself. Check pose clarity, timing, and the sound in the exported video.

A good lip sync pass needs a workable character and a dependable recording. Mouth animation alone cannot repair problems elsewhere in the shot.
Shape keys require a mesh that can form readable expressions. A badly placed mouth or intersecting teeth may still look wrong with accurate keyframes.
WorkaroundFix the model and test its extreme mouth poses before timing the dialogue.
Background sounds can hide the consonants you need to identify. Guessing their positions makes the lip sync harder to judge.
WorkaroundUse a clearer voice recording or clean the audio before animating.
Hearing sound during editing does not prove the rendered file contains it. Render and audio settings need their own check.
WorkaroundExport a short test and play the resulting file outside Blender before rendering the full scene.
Many speech sounds share similar-looking mouth shapes, especially from a distant camera. Attempting a distinct pose for each sound can make the face twitch.
WorkaroundFavor readable closures, vowels, pauses, and the overall rhythm of the performance.
A Blender lip sync workflow gives you direct control over an existing character's mouth animation. If you are exploring a separate video concept, describe the speaker, framing, and dialogue you want to investigate through Lipsync's video-service link. Check that service's current capabilities before treating it as a replacement for Blender rigging or animation.
Import or prepare a voice recording, then build a few readable mouth poses for your character. Animate shape keys on a 3D mesh or switch mouth drawings for a 2D character, placing the changes against audible speech beats. Preview at normal speed and check the exported video with sound.
No. Effective lip sync groups many sounds into a smaller set of visible mouth poses. Clear lip closures, open vowels, and rests usually matter more than matching each written letter.
Use the recording as your reference rather than applying one fixed offset to the whole line. Place a closure where the lips visibly need to meet, then preview the opening into the following vowel; adjust by eye and ear at playback speed.
Yes. Prepare aligned mouth drawings, then change the visible drawing or frame as the character speaks. The exact controls depend on how you built the 2D character, but the timing and playback checks are the same.
First play the exported file outside Blender to confirm that it contains the expected audio. If the sound is present, compare its start and timing with the animation timeline, then check your render frame rate and any changes made to the audio strip before exporting again.
