After opening the software and adding the video material, we need to use the "mixer" function at the bottom to set the love special effects material, so as to edit the special effects.
Next, click on your own video, use the chromaticity function to select the black color in the love material, and then adjust the threshold to remove the black image background.
Finally, the material of love special effects is moved to the position corresponding to the lighter, and the video with special effects is exported and saved to the local mobile phone, which can be directly released to Tik Tok.
