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.

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.

An Interview with Tony Vincent

Tony Vincent is a well-known technology guru and teacher of teachers in the K-12 environment. He travels around the country and runs workshops on how educators can better use technology in their classrooms to supplement, extend or support core lessons. ScreenFlow has become a big part of his instructional toolset. He uses it to help him with his presentations and instructional videos, which he often posts at (a veritable treasure trove of resources for teachers and screencasters).

We recently had a chance to talk with Tony about his process is and how he uses ScreenFlow to help him create amazing videos and high quality teaching tools.

SF Team: Hi Tony, let’s start by sharing a bit about your background. Who are you and where can people learn more about you?

Tony: I’m Tony Vincent. I used to teach fifth grade and now I’m self-employed. I make a living helping teachers leverage technology in their classrooms. I spend a lot of time traveling to schools and conferences to lead workshops and make presentations. My website is at

Tony has been screencasting since 2008

Tony has been screencasting since 2008

SF Team: How long have you been screen casting and approximately how many screencasts have you made (or how often do you screencast)?

Tony: I began screencasting in 2008. I’ve used screencasts to record demonstrations of technology that teachers can use for teaching and learning. I fire up ScreenFlow at least once a week to record or animate at least one thing for a presentation or post.

SF Team: How did you get started screen casting?  What made you transition from a teacher to a full-time technology trainer and screen caster?

Tony: I got into screencasting at about the same time I became more involved in training other teachers. As an elementary teacher, my summers and breaks were filled with presentation and travel opportunities. After a few years of working what was essentially two jobs, I made myself focus on one. That’s when I became self-employed and had more time to create instructional materials, including screencasts.

SF Team: What does screen casting help you achieve?

Tony: Screencasting helps me with two important things. First, I love that I can screencast a demo and include it in my presentation slideshows. While I prefer to do live demonstrations, sometimes there’s just not time to leave my slideshow and demo an app, website, or technique. With a screencast, I can embed a video that I can talk through as the screencast plays. With ScreenFlow, I can zoom and annotate to make what I am showing absolutely clear.

Overview of the Interoperable Master Format (IMF)

February 12, 2016 in Video Formats by Alan Repech

IMF PackageInteroperable Master Format (IMF) is a SMPTE standard for providing a single, interchangeable master file format and structure for the distribution of content between businesses around the world. IMF provides a framework for creating a true file-based final master.

Description of IMF Components:

IMF is an evolution of the Digital Cinema Package (DCP) architecture, providing a complete file interchange unit to the distribution channel. While DCP is about theatrical content distribution, IMF is about providing businesses with a master format for creating multiple tailored versions of the same piece of content for different audiences. It allows distribution of unique versions from content owners to service providers, or distributors—and multiple final destinations such as Airlines, Broadcaster, OTT (e.g. Netflix), DVD authoring, and more.

For example, a widely distributed major motion picture may require dozens of different versions in order to support multiple market segments such as airlines, VOD providers, promo spots, or an edit for cable television. IMF eliminates the need to create a dozen plus master copies by separating each market requirement into individual ‘component formulas’ (Composition Play Lists or CPL) that reference the available essence components (namely MXF media files) included in an IMF package. Individual CPLs are used to create versions based on the master essence components for each of the differing market audiences.

IMF is not made up as a single file. It is a standard specifying individual components which together create a complete IMF package. An IMF package includes the following:

Essence wrapped into MXF track files

  • Video essence (J2K up to UHD)
  • Audio essence (24bit uncompressed, any number of channels)
  • Data essence (subtitles & captioning using IMSC Timed Text)1
  • Dynamic metadata (metadata changes over time)

Composition playlist (CPL) – human readable XML

  • Similar to an Edit Decision List (EDL)
  • References track files via UUID instead of directory paths

Packaging data XML (asset map, packing list and volume index)

IMF essences are defined by Application specifications that allow for different codec types, frame rates and resolution. Two application specifications, Application #2 and #2 Extended, are applicable to the broadcast media market. Application #2 supports SD/HD with JPEG-2000 Broadcast Profile; #2 Extended supports UHD (up to 4K) with JPEG-2000 Broadcast Profile media up to 10bit.

Telestream Vantage Support for IMF:

Vantage from Telestream can take an IMF CPL as a master source input to create all appropriate outputs, and can create single segment IMF Master Packages as an output. Vantage currently supports ingesting and outputting IMF Application #2, and Application #2 Extended IMF packages.

Truth and Hype on HDR

January 15, 2016 in Improve Video Quality by Paul Turner

HDR MountainsIn our last blog about Ultra High Definition (UHD), we covered the spacial resolution of the human visual system, and how (horizontally) the highest frequency the average human with 20/20 vision can detect subtends an angle of approximately 1 arc minute (1/60th of a degree) at the retina. There’s another aspect we need to consider, though, and that’s the sensitivity of the eye to variations in brightness The human eye can resolve the wide range of colors and brightness found in the natural world, but our existing TV systems limit the amount of light that the display can produce to the range of 0.117 nits (a nit is a measurement of brightness) to 100 nits for full white. In comparison, the natural world can produce high brightness colors in excess of 1400 nits. So Cinematographers and Directors of Photography have to adjust aperture on their cameras to allow those bright colors to still fit within the available range of TV transmission. The same is true for the range of colors that can be reproduced (“color gamut”), which is again limited to what is referred to as “rec 709 colors”. This results in what is now termed “Standard Dynamic Range” (or SDR) images. It’s not perfect, but it’s the best we’ve had so far (and it was largely determined by the available CRT technology at the time the specs were written).

Technology advances, and we now have display technologies that can produce a significantly wider black-to-white range, along with being able to reproduce a much wider set of colors. The result of both of these is displays that are capable of producing images which are much more vivid and true-to-life (assuming they were shot with this display technology in mind, of course) – this is what is now referred to as “High Dynamic Range” (HDR) images. The displays themselves are only part of the story, however. Cinematographers/DPs must now set up their cameras to capture a much wider dynamic range, and the transmission and processing (not too much of a problem there!). The colorists need to work their magic in HDR color space (not too much of a problem there, either). But the processing equipment needs to be able to work on signals of 12 bits or larger, in order to process these images. Generally speaking, this means that these processing devices must have an internal video pipeline of 16 bits. If not, the resultant processing will “crush” the dynamic range of the image, which goes against the whole point of HDR – in the worst case, they may throw away bits, which will result in significant contouring.

But there’s a bigger problem than that: whilst you can already find TV sets which are labeled as being HDR capable, there are no standards as yet for the format to be used for delivery of HDR material – in fact, the CEA has only just announced the industry definition for HDR compatible displays themselves. We have to consider legacy support as part of the process– how should an SDR set display an HDR signal? There are several approaches, some of which separate the signal into SDR images with a sidecar transmission that provides the additional information needed to recreate the HDR signal in an HDR display. Others use metadata to tell the SDR set what to do with an HDR signal. HDR is unlikely to achieve widespread adoption until this standardization issue is resolved.

One thing that is certain, though, is that HDR is very much at the forefront of everybody’s mind when considering new television technologies. You only have to see the images produced by a properly sourced HDR display to understand the impact this technology is going to have on TV viewing. In fact, a well set up 1080p HDR image will blow away an SDR 4K image in almost every respect – we just need to standardize on the delivery format and EOTF/PQ (the HDR equivalent of Gamma) so manufacturers know what to design to.

At Telestream, we are always watching developments such as this, to ensure our customers have access to all the latest technologies. Vantage was engineered with a 16 bit (award-winning) video processing system and pipeline, so is perfectly poised to process HDR material – in fact, for certain input/output configurations, we already can!
