Start your face swap video with a simple clip
A short shot with a clearly visible subject is a better first experiment than a busy montage. Choose steady lighting, moderate movement and an unobstructed face. This workspace lets you inspect a local video beside a source portrait, then upload both for processing and retrieve the finished result. Use the preparation steps below to make a stronger brief for whichever processing service you choose.
Movement is the real challenge
A face swap video must stay coherent while the head rotates, the expression changes and the camera moves. An attractive still frame does not establish that an entire clip is convincing. Fast motion, motion blur and a hand crossing the face are particularly useful moments to inspect. Keep your first source short enough to review from start to finish, including the less flattering frames.
Choose a portrait that matches the shot
Look at the dominant angle in the footage before selecting a face photo. A front-facing portrait offers different information from a profile image. Use soft lighting and preserve facial detail. If the shot contains large changes in perspective, a single reference image may be insufficient for a particular model. Avoid treating a face that looks similar in one frame as proof that the whole motion will work.
Prepare a face swap video in the workspace
Choose an MP4 or WebM clip up to 25 MB, then a JPG, PNG or WebP portrait up to 10 MB. The embedded video controls let you play, pause and scrub through the original file. Check that the browser can decode your clip and that its orientation is correct. Files remain local until you choose Detect faces or Generate. The current job is saved in your browser tab so you can resume checking its status.
Understand duration, resolution and cost
Video processing usually involves many images rather than one. A longer duration or higher frame rate increases the work required; higher resolution adds another dimension. Providers may meter credits, duration, file size or output quality separately. Before paying, check the exact allowance for the format you need. This free beta does not guarantee a particular duration or processing time. The server checks the estimated task cost and available allowance before submission.
Review the output as a sequence
When evaluating a finished face swap video elsewhere, compare the start, middle and end. Look for flickering skin tone, drifting eye positions, unexpected changes of identity and broken boundaries around the head. Check whether the intended person alone was edited in a group shot. Verify the output duration, audio track, frame dimensions and playback compatibility before treating the result as ready to share.
Keep the original and label the edit
Save the untouched clip so you can compare timing and recover the source. Use permission-based footage and be clear when a realistic edit could be mistaken for genuine speech or behavior. A synthetic identity should not imply that someone endorsed a product or said something they did not say. Choose a playful, transparent concept instead of relying on an audience being deceived.
Before you begin
Can I make a face swap video here now?
Yes. Select your clip and reference portrait, then Generate. The server submits a Crun task and the workspace shows its status, result and download link.
Can I use the workspace for free?
Yes. The free beta includes a limited processing allowance without an account. Availability depends on both your daily allowance and the shared service budget.
Which video formats are supported?
The current preview accepts MP4 and WebM files up to 25 MB. Playback also depends on whether your browser supports the codec inside the file.
Will my audio be kept?
The provider controls the rendered output. Check the downloaded file for its audio track and timing; we do not guarantee audio preservation for every input.
Is a 30-second or 60-second output guaranteed?
No fixed duration is guaranteed. File size, provider limits and the estimated processing cost determine whether a clip can be submitted within the beta allowance.
How should I test a face swap video service?
Use the same permitted short clip across candidates. Include a small head turn, check all frames and compare the exported files rather than only website examples.
Do I need to install editing software?
No software installation is needed for this browser preview. Your device still needs enough memory and a compatible decoder for the selected clip.
