How to convert image sequence to video using the VSE? I've exported all my frames to .png. 

Could you please explain (step by step) how to convert images to video using the video sequence editor? I used to export as .avi raw before, but because I'm having to constantly start again anytime I come across an error, I've decided to change my method.
In video sequence editor choose "Image".



Use B to select your frames quickly.



In properties> Render> Output, choose an output location.

Directly below, in properties> Render> Encoding, choose a video format (here I've chosen "H.264"). Select "RGB" right next to it, and hit "Animation" at the top.
