Screencast - www.peeceefobie.be

Bon, voilà, c'est mon tout premier essai, alors j'ai fait simple, sans le son. Un screencast avec Screencast-o-Matic, c'est un outil en ligne, et ça a l'air de vachement bien marcher. L'avantage, c'est que la vidéo est directement uploadée sur internet et que le site génère le code pour l'encastrer dans un site ou un blog.

L'horloge mondiale

Un petit gadget qui laisse rêveur : les chiffres sont basés sur les statistiques provenant de l'organisation mondiale de la santé et de la santé, la données de la CIA, etc... Essayez d'appuyer sur le bouton 'now' pour voir les compteurs repartir à zéro et grimper à une vitesse impressionnante. Ou observez une donnée (prenez par exemple le nombre d'espèces éteintes) en un jour, une semaine, un mois, une année. Et puis passez à autre chose pour ne pas trop déprimer. N'oubliez pas d'éteindre les lumières dont vous n'avez pas vraiment besoin ...

Word Count

Essayez donc de vérifier jusqu'où vous arrivez : ce magnifique gadget (cliquez sur l'image pour accéder au site) vous présente plus de 80.000 mots d'anglais, par ordre de fréquence d'utilisation, selon le très officiel 'British National Corpus'.
Alors, vous arrivez à combien : 2.000 ? 3.000 ? 5.000 ? 20.000 ? Vous voyez ce qu'il vous reste à faire ?
Amusez-vous à vérifier :
- à quelle place figure tel mot ?
('scared' arrive en 5530ème place ! 'excited' en 4462ème, 'bored' 5562ème, 'worried' en 2199ème)
- quel mot figure à telle place ? (à la 1984ème place, on ne trouve ni Georges, ni Orwell, mais 'busy', en 2007, il convient de bien en profiter puisqu'on trouve 'enjoyed'. Lesquels d'entre vous deviendront des adultes en 2010 ? A quoi correspond l'année de votre naissance ? J'aurais du naître en 1965 'professor' ou alors en 1964 'birth' = naissance. C'est bien cette période qu'on qualifie de babyboom. Celles qui sont nées au début des années '80, on les encourage à porter la plus belle (la plus grande) robe.
- les mots qu'on devait trouver pour l'examen d'anglais figurent-ils dans la base de donnée ? (Rollerblading n'y figure pas ! d'après certaines sources, il s'agit d'une marque -trademark- qui remplace progressivement l'expression 'in line skating' qui veut dire la même chose. Une marque américaine, alors que le corpus est British. CQFD)
- les 850 mots de la liste d'Odgen figurent-ils dans les 1000 premiers mots ? (Je vous laisse vérifier)
- quel genre de mots trouve-t'on après 80.000 ? (80016 Chowdhury est un mot d'origine sanscrite, que l'anglais très cultivé a appris 'grâce à' la colonisation de l'Inde et du Pakistan, et dont on trouve la définition dans des dictionnaires très spécialisés comme l'encyclopédie Wikipedia :" Chowdhury (variously spelt in different areas: Choudhury, Chaudhri, Chaudhari, Chaudhury, Chaudhary) a Sanskrit and Hindi term literally meaning 'a holder of four', the explanation of which is obscure. In some traditions the term is said to derive from a title for a military commander controlling four different fighting forces, namely navy, cavalry, infantry, and elephant corps. From Sanskrit čatus- ‘four-way’, ‘all-round’ + dhurīya ‘undertaking a burden (of responsibility)’ (Sanskrit dhura ‘burden’). The earliest references are from the 16th century.

In some parts of India, a Chowdhury was a headman of a state or headman of a profession or trade in town. In Cuttack, Chowdhury was a revenue officer of a district(vasooli). Chowdhurys of Punjab, Rajasthan and Haryana are mostly Jats and Gujjars. Under Ala ud din Khilji.

During Mughal times the Chowdhury was the highest caste and of it were three superior classes of landholders: Chowdhury, zamindar and taluqdar. Chowdhury in late Mughal times was taken as next to zamindar in rank though socially a Chowdhury was considered superior to a zamindar. "Roy Chowdhury" was used by zamindars of Bengal.

Apart from north india, South Indian Chowdary's are different in ethnicity but the job is same. South indian chowdary's are also landlords and a holder of four. Chowdary's from Andhra Pradesh are reffered as Kammas and from Tamil Nadu is reffered as Nayakar's.

Chowdhurys are also a caste in Pakistan, they are the highest caste (land lords). Pakistan has adopted the caste system right from its independance from india. Other high castes include Rajah.")
Ce site a reçu de nombreux prix, et de nombreux jeux se sont développés tout autour : concours de poèmes composés de mots se suivant dans l'ordre de fréquence, etc ...
Il y a une autre section sur le site, appelée 'query count' (comptage des recherches sur le site), où les mots apparaissent par ordre de nombre de recherches effectuées pour trouver leur position dans le classement : je vous laisse deviner quels mots sont le plus fréquemment l'objet de la curiosité des visiteurs ...

Knocked Up - En cloque

Une autre blonde, américaine elle aussi, découverte grâce à Grey's anatomy, Katherine Heigl, s'épanouit dans un rôle de femme active qui se retrouve dans la situation d'une grossesse non désirée, dans 'Knocked Up'. Il y a plusieurs versions de la bande annonce : allez voir sur le site du film pour vérifier. Après la bande annonce tout public (celle pour plus de 18 ans n'est pas visible hors des Etats-Unis), je vous sers un montage d'interviews avec des séquences du film : Katherine n'arrête pas de manger et boire pendant la séance !

How to Videos


Dans le même esprit, un autre site qui regorge lui aussi de vidéos, puisque c'est sa vocation essentielle.
Il comporte une section principale "how to", qui consiste en : "Our How To videos are clear, precise videos made to guide you through a wide range of practical problems, tricky situations and delicious recipes. They'll show you How To do just about anything."
Une autre section intitulée "Ask the expert", qui se définit comme suit : "Made in conjunction with the world's leading authorities on a vast range of health, legal, social and practical subjects, our Ask The Expert videos allow you to access the knowledge and experience of top-class experts. Free of charge! Professionally made, they are step-by-step guides to life's most important issues. Need expert advice? Look no further."
Et une troisième section, plus ludique, intitulée "Just for fun", ainsi commentée "Take a look. VideoJug isn't all about health problems and DIY. These videos are about magic tricks, fun experiments, card tricks, drawing, dancing, party games and hundreds of other ways to brighten up your day. Enjoy."
Ce qui est très intéressant sur ce site, c'est que toutes les vidéos respectent un modèle de base, et qu'elles sont accompagnées d'une transcription du texte lu par le commentateur dans la vidéo.
Bien entendu, il y a une section "computers", à l'intérieur de la section "Technologies and gadgets". Comparez cette version - et le texte qui l'accompagne - aux vidéos du texte "how to build your own computer" de "how stuff works".

VideoJug: What Components Are Inside My Computer
Et le texte :

What Components Are Inside My Computer

A guide to the major hardware components found in a computer tower.

Step 1
The Major Components
The major components of a computer are:

The Motherboard

The CPU or Central Processing Unit

RAM or the Random Access Memory

The Graphics Card

The Power Supply

The Hard Disk or Hard Drive

The Optical Drive - also known as a CD or DVD Drive
Step 2
Hardware and Software
All of these components are usually found within the tower of a desktop computer. They are referred to as "hardware". Hardware can be thought of as the actual physical components that go into the computer. "Software" refers to the programs and systems that operate within the hardware.
Step 3
The Motherboard
The motherboard is the “heart” of the computer. It is the largest and most fundamental component of a PC and every other component is attached to it in some way. This is because all the different components use the motherboard to communicate and work with each other.

The motherboard has a series of slots, sockets and connectors for attaching the components of a PC.
In most cases, the memory, accessory cards, and CPU are installed directly onto the motherboard. The drives and peripherals communicate with the motherboard through wired connections.

There are a wide range of motherboards to choose from. They differ in features, speed, capacity and the CPU supported. They also differ in size, shape and layout, this is commonly referred to as the "form factor"
Step 4
The CPU
CPU stands for Central Processing Unit. This is the brain of the computer and is often referred to as the "processor" or the "chip". It is found under a heat sink and fan and sits directly on the motherboard.

The CPU directs, coordinates and communicates with the other components and performs all of the "thinking". It's not really thinking, what a CPU actually does is perform mathematical calculations. It is the software that people write that translates those calculations into useful functions for us.
Step 5
RAM
RAM stands for Random Access Memory, and comes as modules in predefined amounts. It is also found directly on the motherboard and usually in one, two or four slots. The memory chips store information, temporarily, for short term use by the CPU. RAM is used to store information for files that are actually being used by the CPU at any given time.

The computer's RAM memory is an entirely different thing from the hard disk "memory". The hard disk stores information "permanently" for long term use.
Step 6
The Graphics Card
The graphics card or video card translates information into the graphics and text that appear on the monitor screen.
Most motherboards now include a slot specifically designed for the graphics adapter called the AGP slot. This stands for Advanced Graphics Port.
Modern graphics adapters usually incorporate some memory right on the card to improve their performance.
Step 7
The Power Supply
This supplies power to the other components, which is why it has so many wires coming out of it.
It is usually positioned at the back top corner of the computer case. The power supply has a fan built into it to keep itself and the computer cool.
Step 8
The Hard Disk
A hard disk - which is also called a "hard drive" - is much like a filing cabinet. The programs and data are stored on the hard disk and the computer accesses them as they are needed. When the computer accesses the hard drive, it is reading and moving the stored information into the RAM memory. That memory is the temporary workspace. However, the original file is still on the hard disk and is left undisturbed until the file is saved.

When the computer stores or "saves" information, it writes the data to the hard disk. That process results in the old file being replaced or modified with the new information. If you save data to a new file, or install new software, the information is written to the disk in an available, unused portion of the disk.
Step 9
The Optical Drive
The optical drive is often called a DVD drive, or a CD drive. It sits at the front of the computer for ease of access, and uses a laser to read and write information to CD's and DVD's.



Cette autre vidéo vous explique comment procéder pour créer votre propre vidéo pour le site Videojug.com

VideoJug: How To Make A 'How To' Film
Et en cliquant sur l'onglet "Text version", on obtient carrément l'intégralité du texte. Comme ici :

How To Make A 'How To' Film

Make your own 'How to' film, and share your wisdom with the world on Videojug!

Step 1
You will need…
Step 2
Choose a topic
Your film could be on anything you like - 'How to apply mascara' - 'How to skateboard' 'How to grow tomatoes' - 'How to paint a fence'

Just remember that it can't be offensive and it mustn't contain music or footage that you don't own or have the authority to use.

Most 'How to' films are between 2 and 6 minutes long, but if a subject is particularly complicated, they can be up to 15 minutes.

Watch some of our films to get a feel for how they work

We're going to make a 'How to' on chopping an onion.
Step 3
Plan it out
Think about your topic and work out what you want to say. Break it down into steps.
Step 4
Write a script
Now turn your ideas into a script. You'll find a template you can use at www.videojug.com/help/uploading.

Start by writing an introduction. Then work through the different steps required to achieve the task, giving each step a title and describing as clearly and simply as possible what to do. Get a friend to read it to check that it's clear and easy to understand.

There are 2 ways to make a VideoJug. If you want to present your script, simply memorise it and speak it to camera as you film.

Or you might find it easier to record the script separately as a voiceover, and add it to the film while you are editing. Then when you are filming, you can concentrate on getting the actions right.
Step 5
Plan your shots
When writing the script, you probably got a good picture in your head of how you want the film to look. Note down the shots you need to get.
Step 6
Location
Once you've got your script, decide where you want to film. This may be in more than one place.

Wherever you choose, make sure that you have enough space and light. Remember that filming with a window in the background is not a good idea. The bright light from outside makes objects in front of the window seem darker than they are.

If you are going to present your script to camera, check that the room doesn't have too loud an echo.
Step 7
Prepare to film
Move any furniture into position. Get your props together and gather up your equipment.

It is possible to film yourself by setting up the camera on a tripod, but it's easier if you get a friend to help - you can get a wider variety of shots that way.
Step 8
Get filming
If you are going to present your script, it's a good idea to use a clip-on microphone. If not, you can speak your script directly into the camera's microphone or into your computer's microphone, either now, or when you are editing.

Set your camera to film in a 4:3 ratio rather than widescreen, and start shooting. Be creative and enjoy yourself but don't go overboard. Remember to get all the shots that you need, and make sure that they clearly explain every step of the process.

Don't zoom in and out too much and keep the camera as still as possible. Ideally you could use a tripod for most shots. Too much movement distracts the viewer from the image that you are trying to present.
Step 9
Transfer to computer
Once you are happy with all your shots and have finished filming, you'll need to transfer your footage into an edit program. There are lots available.
Step 10
Edit
Keep your script by you. Look through your footage and put it into order. Be as creative as you like when cutting your film - just make sure that what's going on is really clear, and that the pictures and words work well together.

If you like, you can add onscreen step numbers and step titles so that the process is broken into its different stages. You could also add onscreen captions for any points in the script that you feel are especially important. It's very useful to caption any weights, measures or timings.

Design title and credits pages for the beginning and end of your film.

When you've finished your 'How to', test it out on a friend.
Done
Now send your film to us. Find out how to do this by watching 'How to Upload a film to VideoJug'.
