Meeting notes from VMG meeting held on March 7, 2011.
========= Here are a couple of quick tips to get your feet wet with html5 video ==========
If you're viewing a video on youtube, add the following parameter to the url to force it to playback in html5: &html5=True
For instance: http://www.youtube.com/watch?v=NJd_Wl7yMVo&html5=True
Note the ability to playback the video at 1.5x or 2x speed, and display the captions as a clickable transcript.

For a while everything was running smoothly but, as editing advanced to about the 2-minute point, the audio went out of sync by approximately 3-4 frames. That was the clue that I had a discrepancy between 30 and 29.97 fps. But, I had set my sequence to 30fps to match the raw footage I had imported. So what was going on? What I was doing wrong?
Kenneth Chan at Meyer Library was instrumental to figure it out. Thanks, Kenneth.
It turns out that importing an MP4 file shot by a Flip camera to FCP is not as intuitive as I thought it might be.

Together with Kenneth Chan at Meyer Library we were able to figure it out.

What is it?
Hardware and software solution for the capture, encoding and distribution of classroom-captured media.
How does it work?
Specific hardware and software installed in the classroom that can be scheduled to capture classroom content, including anything projected onto the screen via the VGA or DVI signal to the lcd projector.
Almost everyone in attendance is tasked with encoding video - Mostly Flash, some QT, couple WM
Episode is software used for encoding - allows the creation of all these video formats
Pre-processing is the first step in the process - de-interlace, resize, crop, add watermark, etc. - this can add time to processing, but is very important in preparing video for encoding.
Encoding (or transcoding in this example) is the process of compressing the video using a specific algorithm, or codec.
Understand the specifics of your ingest format:

About Kenneth Chan
* Meyer Tech Desk and Multimedia Studio Manager
* Teaches CS2C: Multimedia Production (GarageBand, Photoshop, iMovie/FCP, iDVD)
* Wiki at http:/meyer.stanford.edu
Demo capture of HDV video using the Sony HVR-Z7U camera capturing direct to compact flash card.
Discussion of differences between HD and HDV formats. HDV uses MPEG-2 (produces .m2t files)
Camera -> Encoder (MP4 reference with timecode) -> Content Editor -> Final Cut Pro EDL -> RAID storage -> Encoder (FLV, WMV, MP4) -> Website
ClipWrap - allows native editing in FCP $50 - most units are FAT32, so 4GB limit. ClipWrap stitches those together.
1080 progressive frame footage shot (1920x1080). Drag 'n drop into FCP with audio - .mov file has HDV file in it.
VMG meeting - Thursday 4 September, d.school
Joseph Kautz - Student Video in the Digital Language Lab
Summary: The student videos presented illustrate the Language Lab's role as
a physical and virtual cross-cultural encounter environment.
Student Video #1 - SOCA Mural Project
Members of SOCA (Student Organizing Committee for the Arts) drew the first
chalk mural on the Language Lab's new chalkboard wall and documented the
process for their website.
Large meeting today -- about 45 attendees
Topic for discussion - Online video distribution --
Wide gamut of new to experienced users streaming video on campus.
Trade-offs and experiences...
Start: working with video - what kinds of consideration when choosing a platform for distribution?
- backend support (IT dept or group)
- length of content - short vs long and bandwidth, speed
- analytics - logs
- audience - restricted access / access control / rights / DRM / content
- image quality
