Agenda l Windows Media Tools v 4. 1 Ø Ø l Windows Media Encoder v 7 Ø Ø l Customer scenarios Business opportunity Windows Media solution Best practices for deployment Resources

Encoding To Windows Media Live Distribution Live Content Production Workstation Live Feed u Live u No Editing u Time! Encoder or Tool Input u MPU u Multiple encoders Stored WM File Stored Content: DAT, Beta, DV, CDROM, DVD Streaming from a WM Server Windows Media Services Web Server Streaming u Multiple bit rate u Single stream for web server and download and play from a Web Server Download & Play

Video Capture l Beta Ø Ø l DV Ø l Capture full-size, full-framerate Deinterlace Use progressive scan if possible Film Ø Ø Inverse Telecine (24 fps progressive) Crop off letterbox borders

Clean Up Your Video! l l l Deinterlace / inverse telecine Crop off black edges! High-quality scaling Boost contrast Noise reduction vs. blurring

Image Settings l Image size Ø l Frame rate= even divisor of source Ø Ø Ø l Doesn’t have to be 4: 3 aspect ratio NTSC = 30 -> 15, 10, 7. 5, 6, 5 PAL = 25 -> 12. 5, 6. 25, 5 Film = 24 -> 12, 8, 6 Datarate Ø You never get 100%

Compression Settings l l Video quality = fps vs. clarity Intelligent streaming Ø Ø Safety margin for net congestion Scales to a range of connections

Windows Media Video Guidelines Microsoft MPEG 4 v 3

Input Guidelines Audio l Get a good soundcard Ø Ø l Use a mixer Ø l Event, KRK, Alesis, Mackie Use a good microphone Ø l Mackie 1202 VLZ, Samson Mixpad 9 Use good speakers Ø l Sound Blaster Live, Echo Darla, Gina, Layla Record at 44. 1 k. Hz, 16 -bit or better Expect to pay at least $50 Set audio levels correctly Ø Make it hot, but not too hot

Noise Removal l Avoid Noise If Possible Ø l Common Noise Problems Ø Ø l Record from a good source and avoid background noise Broadband: Tape hiss, Fan noise, Air conditioners, 60 Hz electrical Digital Clipping: Recorded too loud or improperly mixed Clicks, Pops and Crackles: Vinyl, editing and digital errors Background Noise: Trains, Planes and Automobiles Use Sonic Foundry Noise Reduction Ø Four plug-ins designed for different types of noise

Dynamic Range l Use a Dynamic Compressor Ø Ø l Evens out audio levels Only necessary if it has not been done previously Normalizing Ø Peak normalize to maintain dynamics § Ø RMS normalize to make different files sound equally loud § Ø l Normalize to – 1. 5 d. B ‘peak’ to keep codecs from clipping Normalizing to – 15 to – 12 d. B RMS is fairly common Peak Limiters make content REALLY loud at the same volume Frequency dependant dynamics Ø Sibilances and Plosives – Use Multiband Dynamics

Creating Content with Windows Media 4. 1 l Comprehensive suite of tools included: Ø Ø Ø l Integral support for: Ø Ø Ø l Windows Media Encoder Windows Media On-Demand Producer Windows Media Author Power. Point 2000 Terran Interactive Media Cleaner EZ for Windows Media Advanced audio and video CODECS Intelligent Streaming Synchronized Multimedia Great third party tools

Windows Media Encoder 4 Encoding engine for Live (and on-demand) l l l User-Friendly UI Template-based output New controls for Intelligent Streaming Author and store live content Mix with scripts and urls on the fly Encode live or AVI, WAV and MP 3 files to Windows Media

Encoder Automation Windows Media SDK l l l Remote control of encoder (and interfaces) Real time insertion and synchronization of arbitrary data and script commands Start, stop, record to ASF Control and get information on a wide variety of properties: Ø Bandwidth of encoding stream Ø State (start, stop, recording, etc. ) Source code kit available for advanced applications

Windows Media On-Demand Producer l l l Easy ONE STEP encoding of audio/video Add Table of Contents (Markers), URL flips and closed captioning Excellent Video Controls and Audio enhancements Batch Encoding supported Includes HTML Templates

Adobe Premiere Export Plug-In l l Easy Windows Media file creation for the #1 video editing tool Encode to Windows Media directly from within Premiere Common Template stream formats Easy steps to test and edit ASFs

Live Encoder Configuration Hardware requirements l Rules of Thumb Ø Ø l Higher quality (high bit rates) require more power Multiple or Fast processors make better encoders You can never have enough network bandwidth For best results, use Windows 2000 Professional Audio/Video Capture cards Ø Ø View. Cast. com Osprey-100: recommended capture card You’ll need a Sound Card though… § § Use a Sound. Blaster-16 compatible card (onboard OK) If you’re buying new, Sound. Blaster Live is a great card…
