This past week I finally got started on my crazy half-formed ideas about an MITx version of 2.007.
Things I learned:
- use camstudio for screencasting on windows (free). Note that past 2gb, or less than 3 minutes using the Intel format at 50 quality (see screenshot later in post), the avi files seem to get corrupted and unusable.
I’d looked into using ezvid, but you can only export to youtube. - use zoomit (free) to draw on the screen in windows
- record in a nice place, not a stone dungeon, because it reflects in the audio
- macs don’t like windows-formatted hard drives, so you can read but not write from non-mac-specific external hard drives
- MIT specific: the “scratch” folder on the building 26 new media / macathena clusters is per-computer, so you have to log-in at the same computer to access those files. I panicked when fcpx froze and I logged in on another computer and didn’t see anything in the scratch folder…
- on linux, youtube-dl blahlink will download the highest resolution version of blahlink video
- fcpx does not like flv files, and likes wav rather than mp3 files (if your recorder gives you that option)

OKAY EVERYONE.
I’m still alive! I lolfailed at making a comic over IAP, but that is okay. Because! I ramped back up into happy excited mode! I hope this lasts more than 24 hours. I’m stressed about The Future but what the heck I am now able to convince myself to enjoy the moment and not be all “I should have done this by now” and “f***there’s a million things I should do, maybe i should just sleep instead.”
Thanks, brain. *scrunches face* I wonder about saying things like this when I am trying to find a job. oh well!
Anyway, I spent the last few days working on a video about hexapods, ostensibly to help people understand the design process for 2.007. (I made 18-servo-pod for 2.007 instead of participating in the contest). I’d taken part in a documentary-making class before, which used the final cut pro installed on the macs in the New Media Athena Cluster in building 26.
(We made this: http://vimeo.com/11305828)
But this was a bit different. For one thing, neither of the two hexapods (linkage and 18 servo) work right now. For another, since it’s a video about the design process, basically I am stuck with whatever media I took 2 years ago. So I have a lot less video and more pictures than might be ideal.
Anyway, turns out video editing software (in my case, final cut pro x) is magical and there’s no need about worrying about timing my screencasts with my audio recordings (which are done separately — I probably read each paragraph of the script 3 or 4 times) (The main advantage of reading it paragraph by paragraph is when you make a mistake reading it, you can re-record just that paragraph).
I used a stand-alone mic from a friend, and transferred sd-card files.
Using multiple monitors
 |
| Note the camstudio video settings, I think way lower would still be fine.. It also used to automatically open the avi file after recording, which got annoying so I turned that off. |
I have two monitors, so I set the rightmost one to be 1280×720 resolution, lower than it can be.
Camstudio has a “select screen” option so it will only record one screen. Zoomit didn’t handle multiple screen as gracefully — I ended up making my right monitor the default (bringing the taskbar along with it :'( ) because it would let me type, but not draw, if I activated it (hit ctrl-2) on the wrong screen.

To find cc license videos, just type “hexapods, creativecommons“.

other shortcuts: < and > for moving items around, ctrl-= for increasing 1db audio level, alt-w for insert gap.
oh I also learned -12 dB is a pretty standard audio level (depends on if you expect your video to be on tinny computer speakers or on real audio equipment) and you never want audio to reach 0 dB (when speakers distory).
