Testing Encoding Speed vs. Quality Setting in Episode

As if Telestream's Episode wasn't already fast enough, there's a way to make you encoding jobs go even faster. Here's some information from a quick test I did on Encoding Speed vs. Quality Setting in Episode.

Here's the source file that I used for encoding:

Video Format: QuickTime

Frame Size: 640 x 480

Codec: DV

FPS: 30

Audio: 44.100 kHz

16 bit Stereo

Duration: 30 seconds

I used the default H.264_Medium compression setting in Episode Pro which uses a 2-pass VBR compression method. For the first encode with the Encoding Speed vs. Quality setting set to 90 my video took 40 seconds to encode. On my second encode I adjusted the same compression setting and switched the Encoding Speed vs. Quality setting to 10. The video took 27 seconds to compress. Now when comparing the quality of both of my output files the video encoded using a quality setting of 10 still looked really good in terms of quality. Most would never notice the difference in quality. This is good news for those that need to compress files fast with Episode but don't won't to loose quality.

On2 Extends Relationship with Skype in New Strategic Agreement

On2 Technologies, a leader in video compression solutions, today announced that it has signed a new agreement with Skype, the world's leading online communications company, to extend Skype's relationship licensing On2's video codec technology.

Millions of people every day use Skype software to communicate with others through free voice and video calls. On2's technology provides encoding, scaling, pre-processing and post-processing of video on Skype. On2 supported the launch of video on Skype in 2005 with the integration of the On2 VP7 codec with Skype 2.0 for Windows. Since that time, Skype launched High Quality Video in October 2007, calling on the On2 codec, allowing users with as little as 0.5mbps available bandwidth to enjoy full screen video calls at VGA resolution. The On2 codec is also used in the recently announced Asus AiGuru SV1 Skype Certified Videophone. The new agreement is intended to pave the way for the On2 codec to migrate along with the Skype service to a diverse array of new devices such as the AiGuru SV1 videophone.

"On2 and Skype hold the same vision for video communications and through our close cooperation we have overcome the barriers keeping video calling out of reach for many," said Matt Frost, Interim CEO and Chief Operating Officer of On2 Technologies. "In the future, you can expect to see even better video quality requiring even less bandwidth, and this will help to make video calling even more commonplace."

The superior compression performance of the On2 codec makes High Quality Skype video calls possible even over data rate connections as low as 300kbps. Among the numerous quality-enhancing innovations in On2 video codecs is Golden Frames, which enables a sharp background image to be maintained with minimal data when the subject in the foreground is continually moving. This feature is also extremely beneficial for packet-loss recovery. On2 video codecs also require far less CPU power for full duplex live video than other compression formats, enabling Skype users with older and less powerful PC systems to enjoy high quality video calls, and allowing stand-alone devices like the AiGuru SV1 videophone to be produced cost effectively, using less expensive processor technology.

"Bringing a great video calling experience to the average consumer is one of Skype's key priorities, and we see On2 as a key partner in helping us deliver this," said Manrique Brenes, Skype's Director of Business Development and Product Management for Consumer Electronics. "Using On2's codecs along with extensive software development and optimization work by engineering teams at Skype, we are able to help consumers overcome bandwidth constraints and deliver best-in-class free video calling for consumers."
