A Video refers to recording, manipulating, and displaying moving images, especially in a format that can be presented on a television.
Video formats are confusing because most video files have at least two different types: the container and the codec used inside that container. I'll list some common video formats that we often used :
AVI (.avi): Most commonly contains M-JPEG (especially from digital cameras?) or DivX (for whole movies), but can contain nearly any format (not Sorenson). Sometimes you'll see a reference to the "fourcc": this is a four-character code (such as "divx" or "mjpeg") inside the AVI container which specifies which video codec is being used.
QuickTime(MOV): Most often used for the locked Apple Sorenson codec, or for Cinepak (free), but can also hold other codes such as mjpeg, etc.
WMV (.wmv): More or less MPEG4; can contain nearly any codec, including several Microsoft spinoffs of MPEG-4 which vary in their freedom and licensing requirements.
ASF ("Advanced Streaming Format", .asf): a subset of wmv, intended primarily for streaming: an early Microsoft implementation of an MPEG4 codec.
MPEG ("Moving Pictures Expert Group"): three video formats, MPEG 1, 2, and 4.
MPEG-1: Old, supported by everything (at least up to 352x240), reasonably efficient, most used in VCD.
MPEG-2: A souped-up version of MPEG-1, with better compression. 720x480. Used in HDTV, DVD, and SVCD.
MPEG-4: A family of codecs, some of which are open, others Microsoft proprietary. A good format for the web.
MPEG spinoffs: mp3 (for music) and VideoCD.
Why we need to convert PowerPoint to Video?
We suddenly find out that a number of people in the world are converting PowerPoint to video, since we live in a world with the mentality of a herd; everyone else wants to do this. But for what, why? I believe many of them are confused. Well, what is rational is actual and what is actual is rational. There are must be some advantages to do so.
First of all, you know that PowerPoint can only be played on PC with Microsoft PowerPoint installed, and sometimes it must be the right PowerPoint version with right operating system, if any of them has problem, your PowerPoint presentation plan can become a deadlocked, but if you convert PowerPoint to video formats, you don't need to worry about it, since video formats can be played on any PC or Mac system. Where video is played means your PowerPoint can be shown.
The next thing is many gadgets like iPod, iPhone, Zune support certain video format; you can import the converted PowerPoint video presentation and then view your PowerPoint presentation on them.Some famous websites like YouTube are support video upload, which gives you a way to share your PowerPoint presentation with others!
Besides, if you want to protect your PowerPoint from others edit, you can convert them to video and sent to others, what they can do is just watching!
I only list some of the advantages, I think there should be more, explore yourself, if you have any good ideas, we hope you can write to us. info@ppt-to-video.com
How to convert PowerPoint to video formats that we need?
Here is just an example:
A number of people asked if it's possible to displaying presentations via apple TV, the answer is yes, and in fact, there are two ways to make Apple TV as a presentation tool.
As we all know: Apple built the device to stream movies and iTunes content, not display PowerPoint or Keynote slides. If we want to make such a thing is possible, the first way can be found on the website is to export PowerPoint slides as images and create a new album in photo folder, then import the folder of images into new album, Finally we use iTunes to sync the new album so that we can displaying presentation via Apple TV. But you may notice that voice-over, music, transitions and animations are lots. That makes the presentations just a dull thing!
We will not talk about the many easy, well-known methods, most people can figure out how to do this. The $49.95 product called Acoosoft PPT2Video Converter, lets you easily create, edit, and convert your PowerPoint presentations to certain video formats such as MPEG, AVI, MP4, WMV, ASF, FLV, MOV, 3GP, 3G2. Ideal for trade show, digital signature, and in-store displays and ready for video podcast. But it is a pity that this product only supports MS PowerPoint, but it does not matter, because keynotes can export to FLV format itself. So if you want to displaying PowerPoint presentations via Apple TV, you can use this product to convert your presentations to MPEG-4 or FLV video format (MPEG-4 is the best), since movies can be streamed, you can stream your presentation to any Apple TV.
The advantage to the approach is that it's nearly kept all the exact timings, transitions, sound and movies, all in sync with the presentations. You can explore more features by downloading a demo.
