Disruptive Technology: Adaptive Bitrate Streaming (ABR)

November 14, 2016 in Improve Video Quality, Production, Tips and Tricks, Video Formats by Rayna Charnley







It’s often said that change is disruptive, and that’s certainly true for the most significant media distribution development in recent memory, which is the advent of new viewing devices for content delivery. With the extension of video viewing from standard TVs to smart phones, tablets, connected TVs, DVRs, and game consoles, today’s media landscape is radically different from just a few years ago.

What used to be all but impossible—the delivery of consistently acceptable image and sound quality despite often uncertain and fluctuating bandwidth— is now taken for granted by viewers on these devices. Adaptive bitrate (ABR) streaming is a key technology in making this work.

End of Vantage Support for 5.0 and 6.0

September 20, 2016 in Vantage by Rayna Charnley

vantagelogoEffective September 30, 2016, we will be discontinuing support for Vantage versions 6.0 and earlier. This does NOT include Vantage 6.1, 6.2 or 6.3.

If you are currently running one of these early versions, we encourage you to update your existing systems to the most recent version.

For those who remain on the previous versions, beginning October 1, 2016 you will have two ways to receive assistance:

  • If you have an active maintenance and support contract, we will require you to update your systems to a currently supported version before we can provide assistance.
  • If you do NOT have an active maintenance and support agreement, we will provide you with a quote to re-activate your maintenance and support plan, then have you update your systems once the new agreement is in place.

As always, we will do our best to provide assistance in emergency situations. However, we will not be able to provide you with software updates or fixes without an active maintenance and support agreement and a currently supported version of the software.

Reducing support for these older versions allows both our Customer Support and Engineering teams to more effectively resolve customer issues. Please contact support if you have questions or need a quote for an assisted upgrade.

We appreciate you as a Vantage customer and look forward to continuing to provide you with assistance for your systems.

What’s truth and what’s hype? [4K, 8K, HDR and UHD]

August 4, 2016 in Industry, News by Rayna Charnley

4K, 8K, HDR or UHD?

The talk on and around 4K/UHD video has increased considerably recently. Specifically, many TV manufacturers have been proclaiming that this will be the year in which higher resolution screens will become the norm. This is similar to what was said about higher frame rate sets a couple of years ago – even though at that time, the only video that could be watched at higher frame rates came from video gaming consoles.

Whether or not that turns out to be the case, both customers and some manufacturers are using the terms “4K” and “UHD (TV) – Ultra- High Definition TV” interchangeably, and this is invalid. Although similar in concept – creating/ displaying an image that is approximately 4x the resolution of HD – the two terms are not technically interchangeable.UHD

Here are some of the questions we are hearing every day:

  • 4K vs. UHD – are they the same?
  • If 4K is good, and 8K is better, is 16K best?
  • What’s truth and what’s hype regarding HDR?

UHD is a term coined by the consumer electronics industry for this new high-resolution imagery. The image size for UHD is 3840 pixels by 2160 lines – exactly 4 times the size of an HD picture (which is 1080×1920). So, twice as many pixels horizontally and twice as many lines – therefore 4x the size.

4K is the term used by the professional video market to denote this higher resolution as used in film and TV production work. The image size in this case is 4096 pixels wide by 2160 lines, so it is slightly MORE than 4x the image size for HD.

In many cases, this slight difference in horizontal resolution doesn’t matter, but be aware that a UHD TV set cannot display a 4K image without either throwing away 256 pixels on each line, or rescaling the image to fit.

Vantage 7: something in it for everyone!

August 2, 2016 in Vantage by Rose Sponder


Another post from our own Paul Turner:

I’m delighted to announce some big news on the Vantage front: we have just released the latest version of our Vantage software.  Vantage 7 contains a number of new features – let me detail some of them for you:


Firstly, version 7 allows Vantage to incorporate the new Lightspeed Live Capture systems into a domain. This new Capture system takes in baseband video and can convert them into a number of high bitrate mezzanine formats. That video can come in via Lightspeed Live’s four SDI inputs, or via one of the 4x 10GigE ports. The system is also capable of ingesting 4K material, again via SDI or Ethernet. The integration takes place through a new origin action, which allows automated ingest directly into a workflow. Read the rest of this entry →

ScreenFlow 6 is here!

June 1, 2016 in News, Product, ScreenFlow by Lynn Elliott

ScreenFlow 6

Click here for a surprise!


ScreenFlow 6.0 Screen Recording and Editing Software is Here!

With great fanfare, we are excited to announce the release of ScreenFlow 6, with partial screen capture, motion animation, audio mixing, loop recording, enhanced encoding and publishing options, and more

Here’s a list of some of the new features:

Partial Screen Capture
Record any part of the screen. Capture just a single application window, define a region, or record the entire desktop.  Now users can capture only the content that is relevant, saving valuable editing time.

Video Motion Effects
Choose from three new motion-animated effects – Spring, Gravity, Pulse.  Users can click to apply these effects to their clips and create professional-looking animations without the hassle of selecting key frames or writing custom code.

Multi-Channel Audio Mixer
ScreenFlow now recognizes and records multiple audio channel inputs from USB mixers.  Record up to 16 discreet audio channels from a single USB input, and mix and adjust them separately in ScreenFlow’s inspector.

Animated GIF Export
Create GIFs right from your ScreenFlow projects. Enables export of short animations for the web, memes, tutorials or social sharing.  Helps you create video for the web that universally supported by most browsers.  Quick and easy for simple content.


Updated and Improved User Interface
New icons in the timeline and canvas for greater control. Users can mute video or audio on a track independently, use a quick-access pop-up to set project dimensions, and mute audio monitors with a new headphone button.

iOS Audio Monitoring
Listen to an iOS device’s audio simultaneously capturing and recording it. Great for mobile gamers, app developers, musicians – anyone who needs to demo an app where audio is a crucial part of the operation.

New Editing Option, Replace Clip
Swap clips in the timeline without changing the overall duration of a segment, or resetting in- and out-points on the new clip.

ProRes 422 and 422LT Export
Export to more ProRes profiles for greater control over output size and quality.

Loop Recording
Set ScreenFlow to create a rolling recording buffer – to enable the ability to record for hours without taking up all available hard drive space. Users can stop the recording at any  time and ScreenFlow will only keep the last x number of minutes of recorded footage that was defined upon setup. Helpful for reporting intermittent computer or application issues.

Publish to Telestream Cloud
Direct export to Telestream Cloud, Telestream’s online, on-demand, pay-as-you-go encoding service. Let Telestream Cloud create as many versions and formats of the video as needed.

And there’s more! For a full list of features, go to

It’s available on our store now ($99). And for our wonderful customers who have previously purchased ScreenFlow on, you can purchase an upgrade for just $34.

Mac App Store customers: For today and tomorrow only (June 1-June 3, 2016) the Mac App Store version of ScreenFlow is discounted! Otherwise, you can go here for more options.

How RaiderTV Streams Daily Live News Program with Telestream Wirecast

May 23, 2016 in Interviews, Product, Wirecast, Wirecast Rockstars by Lauren Runte


It’s 7:55am and RaiderTV, a student produced live news program at Cleveland Middle School, is streaming live to their school’s students and staff.

RaiderTV is part of a holistic curriculum at Cleveland Middle School in Cleveland, TN, under the umbrella of communications that focuses on oral, print, web, and video communication delivery systems. RaiderTV is a class, offered to 8th grade students at Cleveland Middle School, which provides students with real-life experiences in media, communications, and leadership.

The show airs every school morning and reaches 1,300 students and staff and then additionally reaches about 75-100 families after school hours. The broadcast includes the latest news and events at CMS, and it highlights varying aspects of school life. Students produce a special feature segment for each school day. On-demand videos are available for shows from the last two weeks for the convenience of students, parents, and faculty.

There are fourteen total staffed positions, and a student-producer oversees the production. RaiderTV has been recognized both locally and nationally for its high production value and professionalism in its broadcasts.



In the beginning, Cleveland Middle School needed a way to produce their daily news show and tried using various streaming solutions. Unfortunately, the programs were unreliable, used too many system resources, and struggled to maintain audio and video sync. In addition, the pixilation on high motion video was too great and lowered the production quality.


In the end, they implemented Telestream Wirecast live streaming production software. In addition to providing excellent streaming stability, Wirecast allowed them
to use complex graphics during the production of the show without expensive or complex graphics systems with alpha channels. And it was easy to use.

“We consistently produce high quality broadcasts with Wirecast and the best part is that it’s so easy to use that the students just click a button to start the stream,” says Cody Raper, Communications Instructor at Cleveland Middle School.



Their set up:


By implementing Wirecast to produce RaiderTV, Cleveland Middle School has seen an increase in student engagement. Students now have an enhanced awareness of special events and extracurricular activities through the special features on the show. Additionally, RaiderTV is used for trivia questions and content refresher segments, which helps prepare students for standardized testing. In a nutshell, the daily live stream has unified the school, enhanced school pride, and provided an avenue to effectively communicate information.

For more information about how others are using Telestream Wirecast, or to download a free trial of the software, go to Visit Telestream’s ISTE booth #3425 to see Wirecast in action.
