Sound quality will make or break your amateur video efforts. Audiences can abide slightly wonky shot composition or sub-par lighting while you learn the ropes, but poor quality sound is constantly grating and will make it a struggle for anyone to get to the end of your videos. If you can invest in only one thing make it this – a dedicated video microphone to plug into your camera and ensure that your sound is as good as it can be. Start by looking at models from Rode.
