Filming

Film in a quiet place in order to avoid background noise and interruptions.
Make sure that you’re not talking too fast and that you’re making pauses after each sentence/section.
If you can, use an external microphone

Film in a bright room.
Avoid filming outdoors.
Put the camera between the source of light and the subject.
Place your subject in the center of the frame, looking directly into the camera, with the eyes on approximately ⅔ of the height of the image.
Leave a little bit of headroom above the top of the head but not too much.
Avoid cluttered backgrounds.
Place your camera at the eye level of the subject.
Use a tripod, or mount the camera to something stable.
Do NOT use the zoom of your mobile phone
Adjust resolution settings of your camera and record in Full HD (1080p)
Sit 0,6-1m away from the camera
