Semaphore Free Trial
Would you like to reduce the drudgery of visual, frame-by-frame, manual checking? How about improving the quality of your encoded content? And approving more video in less time?
Semaphore takes the guesswork out of QC. In the June 2008 Streaming Media review of File Analysis Tools, Jan Ozer describes Semaphore's Alert capabilities this way:
Unique to Semaphore is quantization level, which measures the compression required to produce a frame, ranging from one (lowest compression) to 31 for Windows Media and MPEG-2, and 51 for H.264 and Flash. While the effects of excessive quantization vary from file to file, once levels exceed eight (for Windows Media and MPEG-2) or 25 (for AVC and Flash), visual artifacts may start to appear.
