Bring your digital photos to life

Microsoft Photo Story is a photo presentation program for Windows XP. If you're looking for a similar program for Windows Vista or 7, check out Windows Movie Maker or Windows Live Movie Maker.

Microsoft Photo Story lets you drag photos onto a window, arrange them as needed, then provide custom narration, transitions, zooms, pans, audio soundtracks and/or custom auto-generated music, then export the result as a WMV file.

Applying such features can prove tricky in some programs, but not in Microsoft Photo Story. The fact is, you don't need to tweak a whole bunch of settings because the program does it for you, automatically generating transitions and zoom/pans without you having to set it up yourself. What's more, the ones generated by default look great.

While you can simply sit back and let Microsoft Photo Story do everything for you, there's still plenty you can play around with if you're feeling adventurous. For instance, you can build your own custom soundtracks for your slideshow. You can pick from a bumper range of music genres, tempos, instruments and effects, giving you the chance to match the audio precisely to the mood of your show.

Output from Microsoft Photo Story is in Microsoft's WMV file format, which is more compressed than MPEGs or other movie type files. You can choose from various resolutions in order to optimize your slideshow. Unfortunately, however, the output movies from the software are not as sharp as they'd be in VCD or DVD format.

It's a shame that Microsoft Photo Story does''t support burning DVDs and VCDs with the created slideshow, and you'll need your own DVD authoring app to do this. There are applications, such as ProShow, that contain burning options and support for higher resolution output, but there's not much that can match Photo Story in terms of its ease of use and automated features.
So, if you want a quick way to create stand-out photo presentations, Microsoft Photo Story is well worth downloading.
Create slideshows using your digital photos very easily with Microsoft Photo Story. With a single click, you can touch-up, crop, or rotate pictures. Add stunning special effects, soundtracks, and your own voice narration to your photo stories.

Then, personalize them with titles and captions. Small file sizes make it easy to send your photo stories in an e-mail. Watch them on your TV, a computer, or a Windows Mobile-based portable device.

It's pretty good.

I like iMovie. It's a good and simple editing system that is really fun to use. But, there are a few things that I wish would change. First of all, the space it takes up. I don't know if there is anything you can do about this, but whenever I record little snippets for a movie, they save to my photos. And I hate that! And to make it worse, when I delete them, I can't watch that part I filmed in the movie cause I deleted it. And yes, I know. There is something you can do about it. You finish the movie, save to photos, then you can delete all the snippets from your photos. But I wish I didn't have to do that. I just wish it didn't add it to my photos in general. Second, the trailers. I wish there was a bit more freedom to the trailers. The app chooses everything for you. You get to pick the topic and everything, but I wish there was more. I don't like how iMovie chooses the music, how long the clips have to be, and how long the trailer is in the first place. I don't usually write reviews, but this app deserved one. Other than some of my complaints, this was a really good app. Everything is free and available, there are more editing possibilities, and it looks very professional. Again, if there's anything you can do about my complaints, I would do it. I feel like these are common complaints and you would get more buyers if you fixed or changed them. Thanks!

I have played it before but I tots love IT###$&@%🍩💓💓

So I played this game before and I've seen it before it's just for some reason it's uinstalled I've already made some but my two favorites are $###tik###$ and $###tok###$what are I love about this game is usually in some edit games they are ads but none in this game! Those two that I said I made them today and they look really aesthetic and pretty anime so you should really install the game it's a really good one for animating if you don't like ads and if your mom doesn't like paying for stuff lol and how I did it was I got this wallpaper app I took some of the pictures from it and I made it into a little video and it's really cool and what I like about it is that you can record music which is really great it's just if there's sound behind it it sounds super weird so you got to tell like your parents to be quiet or something on the tik one I had to re-record it so many times because my mom was making noise so if everything is really quiet that actually won't happen on tok I had to do it like twice or like three times It didn't take long because my mom was in my bedroom and there wasn't any noise. So you should really get this app it's a really fun one I've had it before and if it's the uinstalls go onto the App Store find iMovie and just press the cloud with an a little arrow and it will reinstall and everything will be all better and anyways this is really long so it's OK if you skip to another rate OK bye!!!!!!!

Perfect For Everyone.❤️ But one recommendation.

So I love this app. I've been using it for a few weeks and I can create some really cool stuff. I've been getting more advanced with the editing, and I love everything it can do. You can put text, backgrounds, photos, you name it. My only problem is the music. I have seen some awesome clips and they all have good music. The songs on here don't have words (from what I've seen) and I've been really wanting to create a clip with popular songs. This app is much better then other editing apps I've seen, it's simple and easy to use, beginners won't find it confusing. (I didn't.) Just play around a little bit, and you'll soon figure it out. It also has more advanced stuff. So many different options here, and it's all easy to use! I'm on an IPhone, and I haven't had the storage or lag problems other people talk about. On a computer it is a bit more complicated, but if you are looking for complex editing I recommend using that. The trailers are also amazing. You have so many different options, and it looks so cool and professional! Overall, super simple and easy to use, perfect for anything! Hope this review helped you, and it would be amazing if the developers could add more to the music! If you are an expert editor or you just want to experiment, this app is perfect for everyone!!

Your body feels acceleration in a funny way. When a coaster car is speeding up, the actual force acting on you is the seat pushing your body forward. But, because of your body's inertia, you feel a force in front of you, pushing you into the seat. You always feel the push of acceleration coming from the opposite direction of the actual force accelerating you.

This force (for simplicity's sake, we'll call it the acceleration force) feels exactly the same as the force of gravity that pulls you toward Earth. In fact, acceleration forces are measured in g-forces, where 1 g is equal to the force of acceleration due to gravity near Earth's surface (9.8 m/s2, or 32 ft/s2).

A roller coaster takes advantage of this similarity. It constantly changes its acceleration and its position to the ground, making the forces of gravity and acceleration interact in many interesting ways. When you plummet down a steep hill, gravity pulls you down while the acceleration force seems to pull you up. At a certain rate of acceleration, these opposite forces balance each other out, making you feel a sensation of weightlessness - the same sensation a skydiver feels in free fall.

If the coaster accelerates down fast enough, the upward acceleration force exceeds the downward force of gravity, making you feel like you're being pulled upward. If you're accelerating up a steep hill, the acceleration force and gravity are pulling in roughly the same direction, making you feel much heavier than normal. If you were to sit on a scale during a roller coaster ride, you would see your "weight" change from point to point on the track.

At the top of a hill on a conventional coaster, inertia may carry you up, while the coaster car has already started to follow the track down. Let go of the safety bar, and you'll actually lift up out of your seat for an instant. Coaster enthusiasts refer to this moment of free fall as "air time." More on that next.

In the 1600s, an English physicist and mathematician named Isaac Newton was sitting under an apple tree -- or so the legend tells us. Apparently, an apple fell on his head, and he started wondering why the apple was attracted to the ground in the first place.

Newton publicized his Theory of Universal Gravitation in the 1680s. It basically set forth the idea that gravity was a predictable force that acts on all matter in the universe, and is a function of both mass and distance. The theory states that each particle of matter attracts every other particle (for instance, the particles of " Earth" and the particles of "you") with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

So the farther apart the particles are, and/or the less massive the particles, the less the gravitational force.

The standard formula for the law of gravitation goes [source: UT]:

Gravitational force = (G * m1 * m2) / (d2)

where G is the gravitational constant, m1 and m2 are the masses of the two objects for which you are calculating the force, and d is the distance between the centers of gravity of the two masses.

G has the value of 6.67 x 10E-8 dyne * cm ²/gm ². So if you put two 1-gram objects 1 centimeter apart from one another, they will attract each other with the force of 6.67 x 10E-8 dyne. A dyne is equal to about 0.001 gram weight, meaning that if you have a dyne of force available, it can lift 0.001 grams in Earth's gravitational field. So 6.67 x 10E-8 dyne is a miniscule force.

When you deal with massive bodies like the Earth, however, which has a mass of 6E+24 kilograms (see How much does planet Earth weigh?), it adds up to a rather powerful gravitational force. That's why you're not floating around in space right now.

The force of gravity acting on an object is also that object's weight. When you step on a scale, the scale reads how much gravity is acting on your body. The formula to determine weight is [source: Kurtus]:

weight = m * g

where m is an object's mass, and g is the acceleration due to gravity. Acceleration due to gravity on Earth, is 9.8 m/s² -- it never changes, regardless of an object's mass. That's why if you were to drop a pebble, a book and a couch off a roof, they'd hit the ground at the same time.

For hundreds of years, Newton's theory of gravity pretty much stood alone in the scientific community. That changed in the early 1900s.

Forces are a big part of physics. Physicists devote a lot of time to the study of forces that are found everywhere in the universe. The forces could be big, such as the pull of a star on a planet. The forces could also be very small, such as the pull of a nucleus on an electron. Forces are acting everywhere in the universe at all times.

If you were a ball sitting on a field and someone kicked you, a force would have acted on you. As a result, you would go bouncing down the field. There are often many forces at work. Physicists might not study them all at the same time, but even if you were standing in one place, you would have many forces acting on you. Those forces would include gravity, the force of air particles hitting your body from all directions (as well as from wind), and the force being exerted by the ground (called the normal force).

Let's look at the forces acting on that soccer ball before you kicked it. As it sat there, the force of gravity was keeping it on the ground, while the ground pushed upward, supporting the ball. On a molecular level, the surface of the ball was holding itself together as the gas inside of the ball tried to escape. There may have also been small forces trying to push it as the wind blew. Those forces were too small to get it rolling, but they were there. And you never know what was under the ball. Maybe an insect was stuck under the ball trying to push it up. That's another force to consider.

If there is more than one force acting on an object, the forces can be added up if they act in the same direction, or subtracted if they act in opposition. Scientists measure forces in units called Newtons. When you start doing physics problems in class, you may read that the force applied to the soccer ball (from the kick) could be equal to 12 Newtons.

There is one totally important formula when it comes to forces, F = ma. That's all there is, but everything revolves around that formula. "F" is the total (net) force, "m" is the object's mass, and "a" is the acceleration that occurs. As a sentence, "The net force applied to the object equals the mass of the object multiplied by the amount of its acceleration." The net force acting on the soccer ball is equal to the mass of the soccer ball multiplied by its change in velocity each second (its acceleration). Do you remember the wind gently blowing on the soccer ball? The force acting on the ball was very small because the mass of air was very small. Small masses generally exert small forces, which generally result in small accelerations (changes in motion).
