 "Hi! I’m ${NAME} and I’ll be talking about ${TOPIC}."
 
+The talks will be broadcast with a resolution of 1280x720px (720p).
+Please make sure the text will be easy to read at that size.
+[You can change the font-size in your Emacs](https://www.emacswiki.org/emacs/SetFonts#h5o-6).
+If you are capturing a single window, you can also resize it before
+you record.
+
+We recommend using dark text on a light background for your recording,
+as this can be easier to see especially for people who are visually
+impaired.
+
+Audio quality can go a long way in making your talk enjoyable to
+watch. Consider the background noise in the room that you are using to
+record, and see if you can temporarily turn off things for your
+recording. If you have a headset or external microphone, try recording
+the audio through that so that you can reduce the sound of the
+computer itself. If you have a smartphone, that might also be a good
+way to record audio that you can then combine with your video
+afterwards. Some people find that draping a blanket over their head
+(including the microphone under the blanket) can help reduce echo,
+which can be a good excuse to make a blanket fort. (It's for
+EmacsConf!) 
+
+You can also upload a 30-second sample of a quiet recording (no
+voiceover) in the same room that you recorded the presentation in, and
+we can try to use it to process your main presentation for noise
+suppression.
+
+Many speakers prefer to record and edit the audio until they're happy
+with how it fits in the time, and then add the slides or videos
+afterwards. It might be easier than trying to do both the audio and
+the video in one go.
