Encoding and Compression
Compression is defined as taking large files and making them smaller. Compression works by
eliminating redundant information. There are two types of compression:
1. Lossy - This method eliminates data to tightly compress it. Usually, this means the
repetitive or redundant data so the resulting output is NOT an exact copy of the original.
Lossy compression is the method used for Internet streaming.
2. Lossless - Uses a compression algorithim that reduces file size but does not lose any data.
Encoding is the process of digitally preparing your files for Internet delivery. Encoding is the file
format around which the compression is wrapped. Each finishedInternet format - such as Real Networks,
Windows Media, Quicktime, MP3 etc. - uses different algorithms (codecs) to create the audio or video files.
The various Internet formats require a solid working knowledge of compression, the individual codecs and
algorithms to insure that your streams are of the highest quality. Good compression and encoding
are accomplished when people don't notice them. At WBC Imaging we never just "push buttons" -
each stream is individually engineered and optimized to deliver your message at the most
efficient bit rate to assure your visitors' a satisfying streaming experience.
WBC Imaging will help you select the best finished format for your media presentation.
CHOICE OF MEDIA FORMATS: We offer all current codecs for Windows Media, Real, QuickTime, Flash MX, MPEG-1, MPEG-2, MPEG-4, and MP3.
CHOICE OF DELIVERY SPEEDS: Your project can be encoded to be delivered at your choice of bitrates for modem, DSL/cable or T1/LAN.
CHOICE OF MOVIE SIZE: Standard video ratios; NTSC (4x3), HDTV (16x9), film ratios, or custom ratios.
TAPE FORMATS: We accept all standard tape formats (i.e., Digibeta, Beta SP, SVHS, DV...) or digital file submission.
PROJECT DELIVERY: Projects can be burned to CD or DVD for duplication or archive purposes or downloaded from our FTP server.
