Thanks! I already did some research on the 7D mk II, but compared to the Nikon D750 (which is about the same price) it lacks some low-light performance. Plus I saw an article on no filmschool about a filmmakers package from B&H which includes the D750, 3 lenses, and an on-camera monitor for just under $4000. So I think I'll keep saving a bit longer so I can get a decent kit.

Here's the package if you're interested:

Good to know! But it seems like an unnecessary extra struggle to monitor your audio... They should have just drilled another hole in the body for a headphone plug...

Try to let the audience in on the story more. I feel like this teaser is just a few shots of a woman calling/watching tv. Honestly, there's nothing in this teaser making me want to watch te full shortfilm.

What's does this woman want? What's her purpose? Try to implement the answers of these questions in your teaser. And at the end of watching the teaser the audience should have the urge to know if she'll make her goal. That's what drives an audience to watch a full movie.

Look at some teasers on YouTube and try to figure out what it is in that teaser that makes you want to watch the full movie.

Good luck!
