Couple Quick Show Notes

I see a common mistake on TV all the time:
The tease video ends up being the first few seconds of the actual story.

Some editor just grabbed the cut tape and stole the first few seconds of it instead of going to the raw and cutting something fresh. This is weak. It tells the viewer that you're just repeating stuff and have nothing new to offer. This type of mistake is another reason to record your shows and watch them the next day-- it's hard to watch your show in the booth. Make sure if you see this to have a follow-up conversation with whoever edited the tease. Ask what happened. Figure out a way that it won't happen again.

Another common mistake I see:
Too many words stuffed into a font.

You only have a certain amount of space for a lower third. If you're writing a lower third that looks like it might have more words than usual, preview it. If you can't preview it at your desk, go to the booth and have the chyron operator pull it up for you to make sure the font doesn't look all smooshed together. Or, just figure out a couple words to cut out so you're not in the danger zone. Same goes for full screen graphics.
