DO NOT SHOW BLOOPERS:  The video you present should be a finished project.  You should not have "takes" with laughing and mistakes mixed in with your finished product.

If you are filming indoors, do not stand in front of windows or open doors.  The back light makes you into a dark siluette and neither you nor your visuals will be visible on the tape.

DO NOT USE ANY ENGLISH.  Your comprehensibility grade is based on whether or not a French person would understand you as you speak FRENCH.  If you throw in any English, your comprehensibility grade will drop significantly.

CHECK VOLUME OF THOSE SPEAKING.  Be sure that the people speaking are close enough to the camera microphone.  If there is background noise, make sure that it does not interfere with hearing the characters as they speak.

Beware:  "Fade In" and "Fade Out" makes the video slow and long if you use it between every scene.  If you want to use it, do it only at the beginning and the end of the video.  Remember, news broadcasts move quickly between stories.
