Getting Started
Thank you for purc hasing an Osprey-50 USB video capture device. The CD-ROM
included with the capture device makes it easy to create movies and streaming video
on your computer. It includes hardware and software allowing you to create
streaming video. The hardware and software for included in the Osprey-50 USB
package includes:
! Osprey-50 USB device enables you to take video from an external source,
such as a camcorder, VCR, DVD player, or other device, and store it as a file
on your computer .
! Windows Media Encoder allows you to take your video and create a streaming
media file.
! Windows Media Player allows you to view streaming media content.
! RealProducer software allows you to take your video and create a streaming
media file.
! RealPlayer allows you to view streaming media content.
What is Streaming Video?
Streaming video is a method, which represents a one-to-many, real-time broadcast
of video and audio over the Internet. It can also be transmitted over a variety of
local and wide-area network implementations. It can be a live broadcast of an event
or presentation, or on-de mand prerecorded video (a Re alMedia file).
When the term Streaming Video is used, it generally means audio and video
combin ed. St reaming Audio is audio only.
Streaming video allows users to view audio/video content without having to
download the file to their local computer. The video is "stre amed" to your computer,
which means the player on your side starts playing the content after a short
buffering period, which can be betwe en five to twenty seconds, depending on the
video bit-rate and network traffic. The buffer allows the player to maintain
continuous playback in the event of minor network congestion.
A simple example is a "shock-resistant" portable CD player. These CD players store
three to five seconds of a track from a CD in their memory, so if the player gets
bumped, it doesn't skip. Streaming video works the same way. The player keeps a
buffer of video and if there is any network congestion, the player keeps playing
without stopping. A streaming video player stores more in memory than the CD
player because network congestion can be several sec onds, as opposed to a bump to
the CD player lasting only about a second.
Osprey-50 USB 1
Getting Started
Streaming media also takes into account the viewer’s connection to the Internet. For
example, some people have 28.8K modem connections, others have 56K modem
connections, and some are directly connected via a T1 line. When you create your
streaming video, you need to set a bit-rate for the target audience. Yo u can either
set a single bit-rate, such as 56K, or a bit-rate including multiple settings, such as
28K, 56K, and 100K.
With a single bit-rate stream, only users co nnecting at the specific bit-rate or higher
are able to view the video stream. For example, if you set the bit-rate to 56K, a user
with a 28K-modem connection is not able to view the video.
With a multi-bit-rate stream, you can create a single stream s upporting multiple bitrates, so people with 28K modems can watch the stream along with people viewing
the stream at 100K. To do the same with single bit-rates, you have to create
multiple streams, all set to different bit-rates.
One advantage to having multiple streams of varying bit-rates is each stream can be
configured specifically for the target bit-rate. For example, a video image size of
320x240 (also known as "CIF", pronounced "Sif") is great for higher bit-rate s, such
as 100K. However, it is not a good size for lower bit-rates. A video image size of
160x120 (also known as "QCIF", pronounced "Q Sif", or "Q uarter Sif") is great for
low bit-rate connections like 28K or 56K.
With several single bit-rate streams, you can optimize your content for each
connection speed.

Capturing Video Using the AmCap
Application
This chapter of the manual provides detailed instructions on ca pturing your video
and audio using the AmCap application provided with the Osprey-50 USB capture
device. AmCap is a video capturing applic ation o nly. There a re no editing
capabilities.
There are other applications which you can use to not only capture your
video and audio but also edit, add titles, and add special effects. These
products include: Adobe Premier, MGI VideoWave, and Pinnacle Systems
DC50.
When capturing video from a source, the files can become very large. To help you
determine the approximate size of your captured video, please see "Appendix D –
Uncompress Video".
Capturing your Video and Audio
There are two steps in capturing your video. The first is to prepare the AmCap
application with the correct settings. The second is capturing the video.
Preparing to Capture
Prior to actually capturing your video, the AmCap application must be configured to
achieve the best results.

Placing Your RealMedia File on a Web Page
It is easy to link your RealMedia file to your web page. There ar e a just a few things
to consider:
! Your web site and RealMedia file must exist on the same server
! If your web site is hosted on a remote system, copy your RealMedia file to
that system
On your web page, create a link to the RealMedia file. This is done in the same
manner as linking to an HTM or HTML file.
When someone access es your web page and clicks the link to the RealMedia file,
RealPlayer launches and your video begins playing.
The person accessing your video must have RealPlayer installed.
You should place a link to the RealNetworks page so people can
download RealPlayer if they do not have it installed on their computer.
If you do not have an existing web page, you can still share your video with friends
and family on the Internet by using one of the templates from Your Video on the Web. Access the web site at www.yourvideoontheweb.com and follow the
instructions for uploading your video to the Internet.
For information on other ways to use RealProducer, visit the
RealNetworks web site at www.real.com.

Appendix A - Troubleshooting
This appendix contains a list of known issues that may occur when using the Osprey50 USB device with the RealProducer software. Also see the RealProducer
documentation and the documentation fo r your computer and Sound Card.
Blue Video Screen
The currently selected video input is not receiving an active video signal. Check that
the camera, VCR, or other video source is powered and that its output is connected
to the Osprey-50's input. Chec k that the correct video input is selected in the Control
Dialog's Source page.
Black Preview Video Screen
If you select a Color Format other than RGB o r Grey8, you may get a black preview
screen. The problem is that the application does not know how to decode these more
specialized formats. It must be able to locate a software video compressor on your
system that works with this format.
If you encounte r this situation with a Color Format that you need o r want to use, you
have to obtain a suitable compressor.
Scrambled Video Image
You may have set the wrong video signal format for the signal input you are using for example, you may have told the driver to look for NTSC-M video but are using a
PAL-BDGHI video source. First, make sure you know what signal format your video
source is generating. Then, go into the Signal field of the Control Dialog's Source
page, and click the button for that signal format.
Osprey-50 USB 59
Appendix A - Troubleshooting
Grainy, Dithered Image
Check that you are using a display format with greater than 256 colors. If a 256color format is used, the system can only approximate the actual colors, and does so
with a loss of resolution and precision. You can determine (and if necessary adjust)
the display depth from the field titled Color Palette under the Settings tab of the
Control Panel ... Display.
Poor Video Quality at Large Frame Sizes
Large frame sizes with the deep pixel depth (24- or 32-bit), or complex format
(YVU9 or YUV12 planar), impose heavy demands on the PCI bus's data transfer
capacity. Our experience is that some systems cannot handle these formats at full
frame sizes.
Systems vary in their data transfer limits. The characteristics of the PCI bridge are
often more important than processor speed.
If you are having problems, we recommend that you:
! Use a smaller frame size (480 x 320 or less)
! Use a shallower color format (RGB15 or RGB24 instead of RG B32)
! Try an RGB format instead of a YVU format, and a packed format instead of a
planar format
! If you have a choice of PCs for video capture, try using another system with a
different system board chipset
Unwanted Closed Caption Text
Closed Caption text consists of white or colored characters drawn on black character
cells. In video that contains Closed Captioning informatio n, the first active line of
video in each field contains encoded Closed Caption text. In video that does not have
Closed Captioning information, that line is simply ordinary video.
If you leave Closed Captioning enabled and view non-Closed Caption video, the
Ospr ey-50 USB de vice will attempt to interpret the first line of each field of video as
Closed Caption character codes. Some video may appear sufficiently similar to
Closed Caption data that the software thinks it is Closed Caption text. The result w ill
be occasional randomly drawn text appearing on the s creen.
The solution is to turn off Closed Captioning when you are viewing sources that are
not Closed Captioned. To do so, open the Control Dialog's Closed Caption page and
uncheck the Enable box in the Display field. The change takes effect when video is
restarted after e xiting the dialog.

"Unable to Initialize Direct Draw" Message
in Windows 98
The DirectDraw system files ddraw.dll, ddraw16.dll, and ddhelp.exe must be installed
in the Windows 98 system. Furthermore, th e file version as shown in the file
properties data must have 4.03 or higher in its first three digits. The software will
work even with this problem, except that Overlay draw ing will not be available.
Obtain and install a service pack from Microsoft if you do not have these files.
Unable to Open Driver or Similar Error
Messages
If AMCAP or any other application gives an error message stating that it can’t open
or find a driver for the Osprey-50 USB device, it may mean that the drivers were not
installed properly.
Video Compression and Playback Issues
When capturing video with AMCAP, you have an option of compressing the video
before it is output to the AVI file. The compression is done video a software “Codec”,
which s tands for “Compressor/Decompressor”. A software codec will compress the
video, and decompress it when you want to view the video. This is useful because
compressed video takes up less space than full frame (uncompressed) video, and it
will help to reduce the size of AVI files.
If you use a so ftware codec, keep in mind that other users may not have the same
codecs on their system, and they may not be able to view your AVI file. If you are
encoding with the RealProducer, it compresses the video but the RealPlayer can
deco de it. If yo u know your AVI files will only be used on one system, then you can
use an y codec and not worry about compat ibility issues.
How did I get these software codecs on my computer?
AMCAP can use any available software codec on your system. These codecs can be
installed manually, such as the Intel Indeo codec, or they may have come with other
software applications on your system. If you are not sure how a codec was installed,
then you should probably avoid using that codec, as you may not be able to
determine how to in stall it elsewhere.

DirectDraw
A software interface standard for transferring video processing from a PC's CPU to
the video adapter. The standard was first de veloped by Intel and called the Display
Control Interface (DCI) and is now supported by Microsoft with the name DirectDraw
as a registered trademark. The driver allows an application to send update
information directly to the video adapter.
Direct Capture
Direct, or uncompressed, capture provides the highest quality image, but takes the
most space. A 30-second clip of uncompressed video in 16-bit RGB format, CIF size,
uses nearly 150Mbytes of disk space. The images are digitized version of the input
and have no compression artifacts.
Grey8 Video Format
Each pixel has one byte of data, representing one of 256 grayscale levels.
NTSC-NTSC-M, NTSC-J
The input signal formats used in North America and Japan (NTSC-J). Full-sized NTSC
has 525 lines total, 480 lines visible, per frame and a display rate of 60 fields per
second, or 30 interlaced frames per sec.
PAL-BDGHI, PAL-M, PAL-N, NC
The input signal formats used in Europe (BDGHI), Brazil (M), Argentina, Paraguay,
and Uruguay. Full-sized PAL (other than PAL-M) has 625 lines total, 576 lines visible,
per frame and a display rate of 50 fields per s econd, or 25 interlaced frames per

blue data; the sixteenth bit is unused. This is a "high color" mode, also known as a
"5:5:5."
RGB24 Video Format
Each pixel has three bytes (24 bits) of data - one each for red, green, and blue. This
is another "true color" mode with 16.7 million colors, and is a recommended form at
for capturing images with the highest possible color accuracy.
RGB32 Video Format
Each pixel has four bytes (32 bits) of data - one each for red, green, and blue, plus
one byte of padding. The pixel has 256 shades of each of the thr ee colors, for a total
of 16.7 million color s. This is a "true color" mode.
SECAM

Streaming
Transmission of real-time data, commonly audio and video, from a server to a client
where the client "plays" content as it is received. This differs from downloaded,
cached, or buffered data, which is played after being received in full, or played part
by part.
YUV12 Planar Video Format
This is a complex fo rmat in which there are 12 bits of data per pixel. Each pixel has 8
bits of luminance data. Each group of 4 adjacent pixels shares two bytes of
chrominance data. The luminance, U-chrominance , and V-chrominance data are
organized into separate blocks.
YVU9 Planar Video Format
Similar to YUV12 planar, except that there are 9 bits of data per pixel and each byte
pair of chrominance data is shared by 16 adjacent pixels.
The video and audio files you create can be very large files. However, there is a
simple formula that helps you estimate the amount o f disk space you need pe r
uncompressed AVI file.
The formula for calculating the approximate file size of an AVI (uncompressed video)
file is:
height x width x color depth x fps x length (in seconds)
8,000,000
For example you have a video with the following characteristics:
! Video window size = 320 (h) x 240 (w)
! Color format = 24-bit RGB
! Frames per second (fps) = 30
! Length = 60 seconds
320 x 240 x 24 x 30 x 60
8,000,000
This results in an AVI file of approximately 414.72 megabytes.
Capture Size Limitations
The theoretical limit on an AVI version 1.0 file size is 4 gig (32 bits). However, due
to a problem in the MS API (Application Progra m Interface) used to create AVI files,
the index and seve ral other entries become corrupt if you crea te an AVI file larger
than 2 gig. Also, some players, such as the older MCI control, allow you to only play
back a 1 gig file.

! If you want every application to be able to play back the file, limit the siz e to
1 gig.
! If you're only interested in Media Player and newer apps, limit the size to 2
gig.
! VidCap32 creates AVI files larger than 2 gig, but the indexes are corrupt and
can't be played back with any player. If VidCap32 runs out of space while
capturing, the entire AVI file is marked corrupt.
! You can use the riffwalk.exe utility in the Platform SDK to verify an AVI file.
It echoes an error if the file is corrupt.
The OpenDML committee developed a specification for AVI 2.0 file s. The
enhancements include:
! unlimited file size
! interleaved indexes
! support for field indexes in addition to frame indexes
The AVI 2.0 specification was also designed to be backwards compatible. So an
application which doe s not support AVI 2.0 should still be able to play back the first 1
gig of the file.
For AVI 2.0 files:
! AmCap creates AVI 2.0 format files; VidCap does not.
! AmCap creates AVI files as large as the file system allows. If AmCap runs out
of space, the AVI file is still good.
! Only Windows Media Player and other newer apps can play back the entire
AVI file.
To create a file greater than 4 gig, yo u must use NTFS. Here are the Windows file
system limits:
! A FAT16 partition larger than 2 gigabytes under NT is not visible to MS-DOS
! The NTFS file size limit is actually 2^32 clusters. Current industry standard
hard disk sector size is 512 bytes, giving a 2 terabyte file size limit.
