Method one
Tik Tok's black-and-white mode may be a problem with the filter in the software. The closing method is as follows:
1. First, open a Tik Tok interface and click the record button.
2. Then in the page that opens, click the filter button.
3. Then, in the menu that opens, select another filter.
4. Take the Polaroid filter as an example. When you open it, you will find that the color of the lens has returned.
5. Then click on the location in the blank space and click to start recording and shooting video.
Method 2
1. Click "I" in the short vibrato video, and then click on the three vertical bars on the upper right.
2. Click Settings in the management page where settings occur, and then click Background Settings.
3. Click Traditional, and then click OK in the upper right corner.
4. Click Restart to repair the gray background page.
