Auditorium AV setup

• Turn the podium microphone off by pressing the button at its base.
• Go into room 104 to get the box of AV equipment, containing a small screen, a control panel, a remote control, and lots of wires. Gita has the key.
• Connect the small screen via the coaxial cable to the jack at the rear right of the auditorium. You can connect the control panel to an Ethernet port as well, but it almost never works.
• Use the remote control to turn on the camera at the back of the auditorium.
• Using the podium control panel, bring all the shades down and turn the lights to 75%. The lights can also be turned to 75% by pressing the "2" button on the wall.
• The lights should be at 75% during the introduction (number 2 of the 4), dimmed during the presentation (number 4 of the 4), then brought back to 75% during the presenter Q&A session. It should remain at 75% during the panel Q&A.
• During the introduction and presenter Q&A, use the arrows and zoom buttons on the remote control to control the camera. Use these buttons as rarely as possible, because camera motion is jerky and distracting when viewed on YouTube.
• During the presenter Q&A, walk the handheld microphone to the person asking the question. Make sure you use the microphone labelled "1", because "2B" conflicts with the lapel microphone.
• During the panel Q&A, zoom in on the panel as closely as possible. Don't move the camera again unless someone writes on the board.
• During the panel Q&A, walk the handheld microphone to people asking questions. Make sure to use the microphone labelled "1".

Overfill room (aka library) AV setup

• Make sure the laptop you plan to stream with has Flash installed. Every laptop has its quirks, so the safest bet is to ask someone who's successfully streamed before to bring their laptop. Alternatively, test streaming well ahead of time by clicking on an older lecture: https://echo360.org/section/df8345ec-7d0c-4dc3-b450-65a423c24650/public
• Get the cardboard box containing speakers from Cameron's office.
• Connect the speakers and projector to the laptop. Connect the Ethernet cable to the laptop, and make sure it's using Ethernet by disabling WIFI. You do not want to be streaming on WIFI.
• Go to this website and click on the relevant lecture: https://echo360.org/section/df8345ec-7d0c-4dc3-b450-65a423c24650/public
• The Echo360 stream starts 15 minutes before the lecture. This is a good opportunity to test it. Make sure the video looks big on the screen, and make sure the speakers are working.
• During the lecture itself, maximize the pane showing the slides. During the introduction and presenter Q&A, maximize the pane with the video feed.
• One person should stay in the library to make sure nobody destroys the books or steals the laptop.

Producing YouTube video

• Echo360 takes a few hours to generate the video files. After it's finished, download the HD versions of the video stream and the slides stream from https://echo360.org/section/df8345ec-7d0c-4dc3-b450-65a423c24650/public
• Rename the slides file hd1(X).mp4 and the video file hd2(X).mp4, where X can be any integer.
• Identify the following timestamps: start of introduction, start of presentation, start of presenter questions, end of presenter questions, start of panel Q&A, end of panel Q&A.
• Create a file called cut_timestamps.txt and add the timestamps. As an example, if X=10 in step 2, then the line could be 10,05:00,06:08,1:12:04,1:15:20,1:50:43
• Generate a thumbnail for the video, and name it image(X).jpg. It should be 1080 x 720 pixels. Cameron has already generated thumbnails for all the lectures this year.
• Run process_all_videos.py, which can be found here: http://astro.caltech.edu/~mz/process_all_videos.py . This takes about an hour to process.
• This will generate the file final(X).mp4. Take a look to make sure nothing's seriously wrong, then upload to YouTube.
