FFmpeg is probably being used more than you believe. I think the BBC uses it for some workflows, there is evidence that Laika and Weta may use it, and there is a fork called FFmbc which is targeted for professional broadcast usage. YouTube probably uses FFmpeg to decode as shown by some unique decoding issues (but this was several years ago that I read ...

It's not an illusion - it's called chroma subsampling. Most video codecs do not represent colour in full resolution as a way of achieving greater compression by taking advantage of the way that the human eye is more sensitive to brightness ("luma") than colour ("chroma"). Many codecs don't bother giving you too much colour information when you're not going ...

It's a well known issue that red component in video devices suffers in presentation. The reason is the red color's long wave length and that our eyes respond more to long wave ranges (not to be confused with color sensitivity which would be in yellow-green range). For us to perceive the colors as equal (ref. responsiveness) the green and blue are ...

The main reason is support, usability and control. First, lets clarify that FFMPEG is an encoder, QuickTime Pro is a video utility that happens to include multiple encoders and Final Cut Pro is a non-linear editor and has nothing to do with encoders other than the fact it can output to an encoder (generally QuickTime I believe). For big budget commercial ...

While pure red is tough to match, partly due to our visual sensitivity in that region, I've never noticed any tendency for red to 'pixelate' more than any other color. Maybe you're seeing an artifact of compression? Do you also see this in non-electronic displays like backlit signs, etc? Another answer here claims that manufacturers kept secrets about color ...

"I have computers, recorders, att u-verse and an am radio" Then there's nothing you can't accomplish! (-: Google shows plenty of examples. This was the first hit for "audio delay software free": http://www.fountainware.com/Products/AudioDelay/index.htm

Can't help with freeware, but i can shed some light on the professional side of things. At urgent.fm we use Zenon because most commercial stations in Belgium use it, and our station is one of the starting places for people interested into getting into radio work professionally in our region. That way someone who was trained at our station feels right at ...

Not sure about Windows, but for Ubuntu, you could always check out Rivendell. http://www.rivendellaudio.org/

I use it in my professional production chain all the time. Last week I was using it to batch through dozens of videos that needed subtitles burnt-in. It would have taken me weeks of tedious labour with Final Cut, it took me a couple of days burning the srts in with ffmpeg, and I was able to automatically rename the files and compress them for the various ...

There's another free, more lightweight alternative to wowza and red5 - the nginx-rtmp-module, which frees you from messing around with java https://github.com/arut/nginx-rtmp-module/ and here's a guide to set it up with the free Open Broadcaster Software (which unfortunately is windows only) ...

It varies a little from one server to another, but the basic components are an encoder/streaming client on the local client that takes input from the camera and turns it in to a stream that can be sent to the stream server on the VPS. The job of the stream server (such as Red5) is then to provide a publishing point that relays the stream to viewers. The ...

What you are referring to is called hot linking, and while it may or may not technically be a violation of their copyright or terms of use (check their website for details) it is still generally considered a poor practice since you are effectively utilizing their bandwidth without mentioning that it is their bandwidth. Your best bet is to contact the ...

You may be referring to a "teaser" or "pre-cap". These are clips of upcoming shows designed to pique your interest and remind you of an upcoming episode. An ordinary teaser usually runs separately from the program, where (what we always called) pre-caps are teasers that run at or near the closing credits for an episode -- as in "Next time on XXX..." If ...

I am not aware of any particular term for showing the schedule. It's just a schedule of upcoming programs and may include playing teasers or previews, which are the video clips to promote upcoming shows. It could also be referred to as filler since it is content that is run while the credits are going (which they have to display) but want to fill it with ...

I think the issue you see here is actually because of bright pixels against a very dark background. Most lossy compression takes into account that we are far more perceptive to lightness differences than we are color differences. Depending on the codec used, and encoding options chosen, the blocks used for approximating the video can be fixed size, which ...

You could check out these links to see if they provide what you need: http://www.theneitherworld.com/mcpoodle/SCC_TOOLS/DOCS/SCC_TOOLS.HTML Caption Maker Pro: http://www.cpcweb.com/ And of course Scenarist and Encore, although both are DVD oriented you should be able to produce at least MPEG-2 with closed captions embedded: ...

If you have at least 300-500kps of upload bandwith available you can push an rtmp stream of your live event to a CDN like youtube, dailymotion, livestream ... In terms of software I already used: Livestream, which provides among other things a tool called procaster with which you can broadcast your desktop, or a section of your desktop. You can even ...
