First, download the "Clip" software in the app store, then open the software and click "Start Creation", which will automatically enter the page of album selection. This is to click on the video to be edited and import it into the clip. Then you can see a list of options at the bottom. Click the first "clip", and the following options will become a small branch under the "clip" option. Slide the options bar to the left, then Filter and Adjust. You can choose the existing "retro film" or "film-grade" filters, both of which are very cinematic. If both can't meet the demand, you can choose the "Adjust" option and adjust yourself.
