# Best practices

> Improve lip sync results with better camera angles, clearer audio, stronger source footage, and realistic model choices.

# Best practices

Lip sync quality depends on the source footage, the audio, and the tier you choose. These are the highest-impact improvements you can make.

## Video best practices

* prefer front-facing or near-front-facing shots
* keep the mouth and lower face visible
* avoid heavy obstructions such as hands, microphones, or hair over the lips
* use stable footage when possible
* keep lighting even across the face
* prefer one clearly visible speaker when possible

## Audio best practices

* use clean speech with minimal background noise
* avoid overlapping speakers
* isolate vocals when possible
* make sure the translated audio already sounds natural before enabling lip sync

## Media recommendations

* prefer MP4 or MOV for video
* prefer WAV or MP3 for audio
* 1080p is usually the best balance between quality and speed
* videos above 4K are not a good fit for this workflow

## When quality issues appear

If the result looks weak, check these first:

* the face angle may be too extreme
* the mouth may be partially hidden
* the source footage may be too shaky
* the audio may contain noise or multiple speakers
* the selected tier may not match the quality target

## Choose the right tier

* use `Lip Sync` for speed and general-purpose output
* use `Lip Sync Pro` when you want more detail
* use `Lip Sync Studio` when you are optimizing for the best short premium result
