I am a video editor and graphic designer and I can make your social media videos be better in a few ways.
I can make them look good by colour grading them and adding text, images, motion graphics and other effects. Make them sound good by applying eq, compression and other effects to the audio, adding background music and also adding sound effects to match with the visual ones.
And also make them be really engaging, so they keep the viewer entertained throughout the entire duration of the video.
I can also create eye-catching thumbnails that make the viewer actually want to click and watch the video.
