Demystifying MXF

March 6, 2015 in Employee Spotlight, Industry, Interviews, News, Product, Production, Switch, Tips and Tricks by Lucas Bischofberger


Another great contribution from our very own Paul Turner!

What is MXF?

It’s hard to work in media without coming across the acronym “MXF” when discussing file formats. Once described (by some) as the solution to all file compatibility issues, it initially seemed to cause more problems than it solved. In some cases, these issues were caused by a lack of definitive language in the spec itself, but the main culprit is a lack of understanding of what MXF is and what problem it’s trying to solve. In this discussion, I’ll attempt to strip away the complexity (MXF is described in over 20 SMPTE documents!!!), and give you a basic understanding of the technology. Read the rest of this entry →

Dynamic Ad Insertion (DAI)- A New Revenue Opportunity

February 19, 2015 in Company, Employee Spotlight, Industry, Interviews, News by Lucas Bischofberger

DAIDynamic Ad Insertion

Dynamic Ad Insertion (DAI) is a concept that has been discussed in the cable TV industry for years.   The reason is simple–DAI has the potential to create the largest single new revenue opportunity for content owners and cable TV multichannel video programming distributors (MVPDs) in many years.  Although approaches have been proposed, they have either required significant changes to the hardware infrastructure or required too much manual processing and could not scale. That is all about to change.

On our booth (SL3305) at NAB 2015, we will host our first DAI technology showcase, featuring the newly released Vantage DAI software solution.  This showcase will demonstrate an end-to-end file-based workflow encompassing video, audio and metadata transformation that delivers on the promise of increased ad revenue within a fully automated and scalable software system.

Meet the ScreenFlow-er: Brent Stockwell of Columbia University

February 13, 2015 in Interviews, Meet the ScreenFlow-er by Lucas Bischofberger

Columbia UniversityMeet Professor Brent Stockwell of Columbia University.  Professor Stockwell uses ScreenFlow to flip his Biochemistry classroom.  The results have been impressive.  His recipe, having the students prepare for class by watching a ScreenFlow he creates expounding on the new material, followed immediately by a short quiz to assess comprehension, seems particularly effective.  We also really like the polling done in class (Professor Stockwell uses Socrative) that helps ensure students are following along.

What’s going on in Video Compression?

Video compression

Another great post from Telestream’s Paul Turner!

How do you compress video?

In a previous blog, we talked over the techniques for compressing a still image. Now its time to apply that to moving images. There are a couple of techniques that are in common use, each designed for a specific set of use cases. In broad terms, these fall into the camps of “Intraframe compression” and “Interframe compression”. Those 2 terms look and sound similar, but they are quite different in practice. Let’s start with the simplest one – Intraframe compression.

Intraframe Compression

Intraframe compression basically takes the path of greatest simplicity: as you know, video is made up of a sequence of individual frames, each flashed in front of your eyes for a short amount of time. It makes use of the phenomenon of image retention in the human visual system (flashed images remain on your retina for a small amount of time – look very briefly at a very bright object, and then close your eyes – you’ll still see the outline of the bright object).

5 Tips for Great Homemade Voice Overs

January 29, 2015 in Product, Production, ScreenFlow, Tips and Tricks by Lucas Bischofberger

Voice OverAt some point during your video-making career, you will need to record your own voice over. It’s inevitable. With the high price associated with outsourcing your vocal talent, mixed with the unavoidable “artistic differences” between you and the talent, it may actually be a better idea to keep things in house.

Getting started is a daunting prospect, but once you get the hang of it, recording your own voice over is actually quite fun! There are many things to remember, but these tips should help get you started! Read the rest of this entry →

Who What Why & How: Recording your iOS Device

January 22, 2015 in News, Product, Product, ScreenFlow, ScreenFlow, Tips and Tricks by Lucas Bischofberger

iPadWho What Why & How: Recording your iOS Device

Back in November we released ScreenFlow 5, which included lots of cool new features and refinements, including the ability to record your iOS device right in ScreenFlow.  Once the recording is done, you can use ScreenFlow’s editor to add some eye-catching details, like animated text or Touch Callouts (finger gestures).

Who needs this?

Our initial vision saw app developers being the primary audience for this feature.  Since release, we’re happy to see it’s relevant to a much larger audience. Last November, we were at the MacTech conference and had the opportunity to demo the capability to MacTech’s sophisticated audience.  The MacTech community was very excited to get their hands on the software so they could use this capability in their trainings & tutorials.  In addition.

How Does Compression Work?

January 5, 2015 in Industry, News, Production, Tips and Tricks by Lucas Bischofberger


Another installment on compression from Telestream’s Paul Turner. Click here to read his previous article on “Why Compression Matters.”

Clarifying Compression

In my previous blog, I explained how pervasive compression is in our day to day lives. In a nutshell, it’s used everywhere there is information to be shared – written, spoken, viewed. So the next question is “how do you compress information?”

The idea of compression has been around for many, many years. In all cases, it involves finding redundant information in the data and removing it, and then – potentially – removing as much real information as you can while still leaving the information as intelligible. Now that’s a pretty scientific sentence, so I’ll give you some examples to make it clearer (by the way, the 2 techniques directly refer to “lossless” compression and “lossy” compression respectively).

Why Compression Matters

December 11, 2014 in Industry, News, Production, Tips and Tricks by Lucas Bischofberger

ompressionAnother great post from VP of Enterprise Product management. Thanks Paul Turner!

What is Compression?

It’s hard to absorb how many ways data compression comes into your life today. For anyone involved in the media industry, the terms “compressed video” and “compressed audio” are thrown around like spaghetti. But what is compression actually? Why is it so pervasive? Let’s start with the basics.

First of all, I should point out that the idea of compression is by no means new – it’s been around since the earliest days of electronic communications. The reasons for it then are as valid as they are now. Today, we talk about digital compression; then it was analog compression. No matter: the needs and basic techniques remain the same.
