Several tools to record your desktop

class=”article first_main_article” readability=”58″>

asked a reader the other day how to make a video like openSUSE 12.3 that we saw yesterday. The answer would be divided into two parts, recording and editing . Come to the first, for which we have several tools in GNU / Linux.

screencasting tools different monitor to record your desktop

Starting with the basics, most often cash-, a few commands are enough to record what you see on the screen of our computers. There are different ways to do it, but my favorite is using FFMPEG :

ffmpeg-f-s x11grab 1024 × 768 -r 25 -i: 0.0-sameq ~ video. avi

One must also change accordingly what you see in bold: resolution (-s), FPS (-r) and extension if you want a different format. What better explained in this blog.

Moreover, if you are 3/Shell GNOME users, you just run “ Ctrl + Alt + Shift + r “, automatically saving videos and high quality WebM . Not bad, really.

Passing

“GUI”, ie the shift of software, the best known are recordmydesktop (well, this works for console, but the most common is to pull the GTK interface you see on these lines). Your choices are simple, reaching running in the system tray, from where you can turn off. You will find it in the repositories.

Another option that some time ago we talked about in these pages Kazam, a modern solution that will also find in the repositories of your distribution (and that I show capture looks a little Frankenstein monster, I suspect, by something related to GTK).

Finally, today I discovered thanks to Unixmen Vokoscreen , a more to cover these matters quite good looking and installers for Debian, Ubuntu and openSUSE. Your choices, the same or very similar to the rest, so I invite you to test different alternatives and stay with the best results you provide, and I invite you to share your experience in the comments.

OCAM: Excellent software to record screencasts in Windows

recently spoke of the importance of screencasts and need quality tools to create them. At the time we talk about RecordMyDesktop, an application for a major Linux distributions, and this time we will devote a few paragraphs to OCAM . Is a program for Windows that lets you capture the computer screen in both image and video.

when recording screencasts can not say that there are few applications for Windows, but there are few that actually provide worthwhile results. Most quality programs, Camtasia Studio, for example-are extra , and let’s be honest, not everyone is willing to spend $ 300 on a software license for personal use.

free alternatives are not lacking but many recorded with poor quality or do the infamous watermarks removed the video appeal. Luckily OCAM makes a difference and provides quality tools, without cost or restrictions . The software not only works well but is also easy to use.

OCAM

interface is quite simple: a window to the most important controls and box with which captures screen activity. With button “Record” screencast recording starts, while with “Capture” you get a traditional screenshot in PNG format.

section “Resize” you can set the size of the image or video capture. The program can work in full screen mode, with default resolutions or a manually selected area.

2 OCAM: Excellent software for recording screencasts on Windows

While

OCAM comes preloaded with some codecs , developers offer additional alternatives to download. Once installed and configured can be chosen from the program options. From there it is possible to change the default keyboard shortcuts, the output folder and the time limit for recording video (if enabled).

3 OCAM: Excellent software for recording screencasts on Windows

screencasts and screenshots

OCAM obtained automatically saved in a folder in My Documents. This directory can be accessed from the application interface through button “Open” , a simple function but agile.

One point that deserves mention is also processing speed videos . Other programs of the genre are incredibly slow and make us lose much time. It is logical that the process is longer depending on the length and resolution, but still he manages OCAM well against the competition.

downside we can make the lack of translation into Spanish. Not a major problem but enough for those who do not handle English. Anyway, worth trying this application supports Windows XP, Vista and 7. Then I leave a short screencast recorded with OCAM test.

Record a screencast on Linux with RecordMyDesktop

Among the most used tools in the world of bloggers are screencasts . The screenshots in video serve to illustrate specific points or demonstrate steps, and there are several tools to create them. The problem is that not all programs for creating screencasts functioning as they should.

Some

recorded with a very low quality, while others leave annoying watermarks or are slow in encoding. In Linux there are a few applications to record screen activity, but one in particular has earned my admiration RecordMyDesktop .

This software is my personal favorite because it is easy to use and record with high quality. Also available for multiple distros: ArchLinux, Debian, Fedora, Gentoo, Mandriva, openSUSE and Ubuntu, to name a few. Another point to note is that there are two versions: one that works from the command line and the other with a graphical interface .

In my case I prefer the second option because it is more “friendly”, so the article will focus on it. If you use Ubuntu can find and install it from the Software Center. It’s very light, the controls are easy to understand and has advanced options to control the recording quality.

Note: Tests were conducted in Ubuntu 12.10 but software behavior not vary between distributions.

RecordMyDesktop offers different modes of use. If pressed directly on the “Burn” screencast get a full screen, on the other hand the “Select Window” is used to record the activity of a folder or application. If they right click on the record button on the menu bar and can make capturing a specific fragment of the screen.

Whatever option you choose, you can pause or stop recording from the Stop button in the menu bar

Before capturing

remember screen check the advanced options of the software. What else is there to consider is the amount of frames per second in the video . The higher the number the better the image quality, but processing will slow. Do not forget that the video length also influences the delay time saved.

RecordMyDesktop created screencasts are stored in the folder of OGV format files. If you plan to upload to YouTube or similar video sites, you should convert them to other formats because otherwise it can be processed incorrectly. I recommend an application called Transmageddon because it is quick, easy and virtually lose quality clips.

against RecordMyDesktop point is not always properly recorded screencasts full screen. Many users complain that the videos show a serious pixelation diagonal and are unusable. There is no official solution to this problem, but you can avoid manually selecting the entire area comprising the desktop.

Then I leave a short screencast obtained during the writing of this article to show the quality of the software.

Mark Shuttleworth: “I am very proud of our record of innovation”

first_main_article” class=”article readability=”61″>

is common practice that after the release of version that touch of Ubuntu, Mark Shuttleworth feels one hours at the keyboard to submit to questions from users. Yesterday was the day and WIN Mark talked a little of everything , as you can see below.

Mark Shuttleworth Mark Shuttleworth: I'm very proud of our record of innovation

chat session can be completed in this link, but after giving an overview I prefer the selection of questions / answers have posted OMG! Ubuntu!, But only the juiciest from here to translate / adapt / resume for you. Let’s do this:

Will it end

(Ubuntu) 12.04 to recent criticisms of Ubuntu

(The first part of the response is to accept that Mark is valid criticisms but not all are well and it is impossible to fulfill everyone’s wishes, because they are often contradictory in design issues.)

“ I am very proud of our record of innovation, even before we had Ubuntu One icloud or Windows equivalents, introduced the first external scrollbars, we designed a single Unity launcher icons on the left and Full-screen search before anyone else. Apple Launchpad and GNOME Gnome Shell came after .”

Have you noticed that Ubuntu has dropped in the Distrowatch rankings

(original rating which I subscribe: DistroWatch does not measure the use of distributions, simply page views distributions in place. In other words, has no value as a measure of use.)

“Congratulations to Mint by the jump in qualifying. I am glad that Ubuntu has derived great, and I am sure that Unity will remain the No. 1 desktop environment in the coming years. “

With all the improvements that come with the launch of Qt5 not be better to concentrate efforts version only QML / Qt Unity

“ could be. The Unity-3D team needs to show that it pays to have the two versions in play, and equipment needed Unity-2D show that it can provide an overview of the level we have to Unity. “

Are you committed to maintaining the support and ease of installation of GNOME Shell in Ubuntu

“ That depends on how easy that people do GNOME Shell. I have no commitment if they decide to make it very difficult, or impossible, or keep saying things like “external scroll bars do not support Ubuntu with GNOME upstream “.”

“ We worked hard to influence and improve the design of (GNOME) Shell, but it turned out that the best way to do things was (this is supposed to say to lead their own project) , and we did, and continue to do so .”

Naturally

given one hour to more questions, and for example asked about where they will get the resources needed for Ubuntu plans on phones, tablets and televisions when Unity on the desktop still needs polishing, or if you really think it has something to do against IOS and Android in the field, to which Shuttleworth says “political style “, saying a lot without saying anything (no wet, no). Somewhat in the style of the answers you have read so far, but softer still (somewhat understandable given his position ).
