After importing the video in Adobe Premiere, do these steps in order to improve the video and audio quality.
1. Search from effects for the filter “Shadow/Highlight” if your video was filmed inside a room with low light.
2. If it was filmed outside, in daylight, you can increase the exposure to value 1. Or you can do point 1. Export both versions and see which one you like more.
3. Right click on your audio area, increase the “Audio Gain”, usually to 15. It depends on your camera. If your camera sound recording is low, you can adjust the volume from here.
4. Search from effects for “Mastering” and drop the effect on the audio area.
Now from the effects window, scroll down to “Mastering”, click on the icon and select “Subtle clarity”.
