The article by vuol'essere today a reference for those who want cut a video from one point to another with ffmpeg ( then using the terminal). Strange, true? To change what products we use highly graphical far more graphics you can imagine.
Often the video is too long to be cut, and a full program (with gui and all) consumes too many resources and slows down the system.
The syntax is very simple, in a single line of terminal (more…)
Let's say you have a video from which we extract an audio track. The reasons may be the most varied, we might want to save a special effect in a movie (shot, outbreak, musica d'atmosphere, famous phrase, etc.), or part of a song, the possibilities are endless.
Today let's see how you do with ffmpeg, the usual command-line tool that always shot at stake for encode video, slow them down, adapt them to my TV and more. (more…)
Today we still talk about video editing command line, ffmpeg as well as we will see in broad terms how they work mencoder and sox: is the first part of the project “mplayer“, the second helps us in definition audio. The end result of this tutorial will be the original video (including audio) slowed. In short will last twice.
To begin with we must have a video format “mp4“. If we use our size differs ffmpeg by convertirlo. (more…)
Today I raised the issue of “time lapse”, a particular photographic technique that through the sequence of shots allows the creation of small animations. To get an idea of what the time lapse, I refer you to spectacular video easily available on youtube, or rather those dedicated of this page.
For the good time lapse is necessary to automate the process of shooting, in practice things are not handled personal skill, the better the final result. (more…)
My new TV is a Panasonic Viera Plasma series “S30“, generation (I would rather penultimate generation). Has the ability to connect to the internet, function that allows me through a few applications developed “ad hoc” of see the trailer movies currently in theaters, unload (paying) the latest movies and watch streaming, listen to internet radio in streaming, See Youtube videos, accessing Facebook and Picasa, download a feed updated in real time with the day's news in video format. In short, the applications are wasted. (more…)
Some article ago I've had to adapt the mp3 to playing on the web. The flash player unfortunately only support sampling 44.100Hz, but I have always recorded my songs to a higher quality: 48.000Hz.
I tried some small programs with graphical interface, but I had to resign to the use of command line (in some cases it is almost essential). To convert my mp3s I used “ffmpeg“, doubtless “the” program for multimedia on GNU / Linux. (more…)
