Most free video face swap tools only permit a limited amount of conditions to proceed with the swap. Usually platforms only permit 5-15 seconds of video content, e.g. Vidwud allows 15 seconds.
Additionally most platforms only limit to 3 daily swaps, thus making it tedious to swap a longer video.
Idea on how to get more time
The idea to get more time is to compress and decompress the video by changing the frame rate. This means you take a video and speed it up by 2-4 times, face swap, and slow it down by 0.5-0.25 times.
Procedure
- Choose a video that should have a face swap be done and trim the length to be less than the allotted time after speeding it up.
- Use either YouCut or Clideo to speed up the video. YouCut is better for 3x and Clideo for 4x, both work well 2x. One thing to consider is that Clideo watermarks its creations.
- Use Vidwud or any other free platform to swap the face.
- If you used YouCut to speed up the video by 3x, now slow it down by 0.3x. If you used Clideo to speed up the video by 4x, now slow it down by 0.25x.
How to carry over the audio
By speeding up the video the audio becomes distorted, thus to have the original audio on the final product, you need to extract the original audio. This can be done via an online converter.
Next use Clideo to add the audio back to the video.
