Green Screen Video Production for Online Courses NedimSlijepcevic, Instructional Designer, Eastern Kentucky University
Thank you! • Thank you for speaking at BbWorld ’09. Your efforts are what make BbWorld an event to remember! A few reminders: • We’ve included a two suggested slides to help you quickly introduce yourself and your institution. • Clients have told us that most effective presentations do not focus on institution specifics, but rather provide best practices that can be applied anywhere. So we encourage you to refer back to the learning outcomes you provided in your session proposal and focus on those highlights. • Your session is 45 minutes long – and there will likely be another session in your room immediately following yours, so please be aware of the time! Delete this slide.
Connections Delete this slide. • Connections • Want to share your knowledge with the wider Blackboard community that can’t attend BbWorld? Want to start the conversation before you get to the event? Heck, want to encourage folks to attend YOUR session? Blackboard Connections will be our virtual hub for the BbWorld Event. • We encourage you to post your handouts, PPTs, notes, or any other information to Blackboard Connections either before and after the conference. Simply go to http://connections.blackboard.com/resources/a9da724c5b/posts and post your materials in the Best Practices area! • You must be logged-in to post. Use your Behind the Blackboard username and password, or if you don’t have one, create a login! It’s that easy. • We also encourage you to post to the discussion board, or other areas of the BbWorld Connections group – use the community as a sounding board for your ideas or give a teaser of your session.
Want more? Be green! • Who wants to print out a handout? Instead, check out my posts on the BbWorld ’09 Discussion Board at Blackboard Connections (http://connections.blackboard.com). I’ve posted: • My PPT • Handouts • Rubrics/Tools/???? • Discussion board posts on this topic Example - Update or Delete this Page
What will you learn in this session? • Attendees will learn the following: • Successful implementation of educational videos in learning environment • Steps involved in a budget to moderate video production. • How to set up a video recording studio • Video editing techniques and how and where to gather resources from • Video exporting, compression and ultimately, deploying video to the end user Suggested Page Example - Update or Delete this Page
Located in Richmond, Madison County, Kentucky, Eastern has a distinguished record of more than a century of educational service to the Commonwealth. • Students: 16,000 on campus • Products Used: Blackboard 9 • NedimSlijepcevic (Instructional Designer/Technologist) is a member of a Distance Education and Multimedia Services unit at college of Justice and Safety who is responsible for running and maintaining of 4 online degrees.

Common mistakes while deploying videos in an online environment • Videos for online courses are often long clips of classroom lectures • They often depict instructors teaching a lesson in a classroom • Teaching aides (PPT, images, video clips) are often excluded from the video • Videos are often encoded and delivered in a non accessible format. • Files tend to be too large.
Why is it important to produce your videos? • Videos produced in controlled and timed environment • Instructors prepare the scripts in advance and record exactly what is needed • Multimedia elements such as images, supplementary videos, PPT slides can be added during production • All videos are delivered in a common format with similar file compression • Online videos decrease student alienation and increase retention rates
EKU – CJJS Online course videos sampler • Techniques you just saw: • Utilizing external video clips and imagery from sources such as: • YouTube, Google video, Films.com, stock footage sites (Fotolia.com, iStockphoto.com etc.), clipart collections • Utilizing animation and static imagery to clarify complex problems - Adobe Flash • Scripted and non scripted training videos • Mix of PowerPoint slides and chromakeyed video
Studio Equipment • Camera • Lavaliere microphone • Green screen cloth (green screen, Datavideoor Reflecmediafabric) • Teleprompter • Lighting • LED preferred (cold, low energy, portable)or • Halogen lamps (Very hot, minimum of 2000 watts, blinding)
Studio setup – classic chromakey fabric 250W 250W 250W speaker 2000W Floodlight 250W soft teleprompter Cam
Studio setup – Datavideo fabric with LED lighting 50W 50W speaker 50W Cam 50W teleprompter

Preparations - script • Prepare the speaker in advance by telling him/her what to expect during the shoot • Script should be no more than 4-5 pages long (10-15 minutes) • Make sure scripts are written in a conversational tone • Avoid dating the scripts (e.g. on May 2nd we will have an exam)
Preparations - speaker • Avoid patterned shirts (checkers, stripes) • Tell the speaker what to expect • Relax the speaker with light conversation and jokes • Make sure there are beverages available • Always do a dry run (don’t tell them it’s a dry run ) • Adjust the lights so they don’t blind the speaker • Observe the speaker and give him/her hints after the dry run
Video shoot • If new presenter – have someone run the teleprompter • Observe the presenter and watch out for things such as • Nervousness • Overacting • Not smiling • Dry mouth • Don’t be afraid to call “cut”, even if you are not sure if they missed the line or not. You have one chance for video shoot and Premiere is not Photoshop.
Putting it all together – post production • Video production machine • Windows machine with Matrox RT.X2 hardware accelerated video board • Video storage (2-3 Terabytes, preferably in RAID configuration) • Video editing software (Premiere CS3 or CS4)with chroma keying filter (Mattenee) and Moyea FLV video importer • Adobe Photoshop, Irfanview • Compression • On2 Flix Pro (.Flv) and Apple QuickTime (.Mov)
Gathering resources • Stock image services such as: • Fotolia.com • Istockphoto.com • Photos.com • Search engines such as: • Google • AltaVista • Bing? • Other handy resources: • MS Word Clip art • YouTube • Films.com (Films for the Humanities & Sciences) • Your own camera and Photoshop
Psychology behind video production • Alan Paivio – Dual coding theory • Information is best presented in dual channels – Visual and verbal (audio). • Richard Mayer expanded on this and came up with theory of multimedia learning. • Refer to Nine ways to reduce cognitive load in multimedia learning (Mayer, R. E. & Moreno, R. (2003) for a full list of design principles.
Psychology behind video production • Avoid showing multiple visuals on the screen (speaker + text + narration). If you must, use with moderation. • Avoid multiple verbal inputs (Speaker + narration + another audio channel (music, another speaker) • Exclude extraneous materials (unnecessary glitter) • Simultaneously present images with corresponding words/narration
Psychology behind video production • Spatially connect words with images • Avoid simultaneous textual and verbal redundancy • Personalize your lessons/scripts • Use “clean” design (simple backgrounds, virtual sets) • Don’t be tempted by the excessive visual effects
Exporting & Compressing your Footage • Export in DV format (non compressed) • Use the best quality when exporting • Avoid exporting from video production software (Premiere) • Use third party compression software to finalize your videos • ON2 Flix Pro • Sorenson Squeeze
Exporting & Compressing your Footage • Compression is an art • Determine you audiences average connection speed • Based on average connection speed, experiment with various file bitrates and dimensions
Exporting & Compressing your Footage • Our online videos: • FLV Hi (480x360) • Video - ON2 VP6, VBR, 600 kpbs, 30fps • Audio – 22KHz, 64 kbps, mono • FLV Low (370X278) • Video – ON2 VP6, VBR, 100 kpbs, 15fps • Audio - 22KHz, 32 kbps, mono • MOV (370x278) • Video - H.264, 200 kbps, 15fps, • Audio – AAC, 22KHz, 24 kbps, mono • iPhone (352x288) • Video – MPEG4, 12fps, 150 kbps • Audio – AAC, 22KHz, 24 kbps, mono
CJJS Video Delivery System • Flash streaming server • Web server • Content collection via Bb
