AE is a very professional video processing software With the rapid development of short videos, AE has become a very good short video production software! Using AE to create videos doesn't mean just splicing the videos together. If you want to get a good video effect, adding various effects is the right solution! Here I will share with you a tutorial on how to create a water ripple effect video using AE. Learn it as early as possible and follow the steps in the video tutorial on how to create a water ripple effect. using AE:
Part 1 Step 1: Start with a new solid color layer and move it to the middle of the page as a base for the water waves
Step 2 : Then create a new solid color layer and give it a radio wave effect
Step 3: Adjust the radio wave settings:
Step 4: Then add a Gaussian blur effect to increase the flou. Precompose this layer (shift+C) and call it [Electric Wave]
Step 5: Select the original solid color layer and add a shift effect
Step Six : Because you only need one wave in the vertical direction. Therefore, set the vertical displacement value to a larger value and the horizontal displacement value to 0
Step 7: First draw a star, then set the wave mask to the Alpha mask "Star" ~
Step 8: If you want to achieve the effect of slowly filling water from bottom to top, you can set two [Position Keyframes] for [Star Wave]. water]: at 0 seconds it is below and at 5 seconds it is at the top
Step 9: Finally add a background color and some small decorations~
< p>The above is our entire tutorial on using AE to create water ripple effect videos. Well, isn't it very simple? It maybe easily done in nine steps, so hurry up and start it~How to use the temperature difference of sea water to generate electricity?
1 Prepare the materials. Three or four Jianlibao bottles or 2.5 liter Coke bottles, a few x-ray films, a few No. 3 and No. 4 soft rubber stoppers for chemical equipment, a complete set of bicycle valve cores, a pair of scissors and a knife, transparent tape, double-sided glue and insulating tape, a 502 glue stick.
Production of the 2nd Wing. Use scissors to cut the X-ray film into 28 equal-sized rectangular trapezoids. The trapezoid measures 12 cm long and 6 cm high. The angle between the oblique waist and the long base is approximately 45 degrees. Cut another 4 trapezoids with the same specifications as above but with a height of 8 cm and a short base connecting the two overlapping sides (to use as the surface of the ahe is). Use double-sided tape to stick 7 small trapezoids firmly into a thick trapezoid, making it straight and flat, then wrap it tightly with a large double-sided trapezoid and stick it firmly. To make the thick wing surface flat, you can use scissors or a knife to straighten it, and then seal the thick wing surface with insulating glue. Finally, bend the extensions on both sides of the wing outward 90 degrees. In this way, the remaining X-rays are transformed into three wings according to the above method.
3 Production of the body. Take a Jianlibao bottle (the excessive arc of the bottle head is more natural, and making a rocket head will reduce the empty space)Air resistance) Cut it crosswise 11cm from the lower end, use insulating glue to stick the part with the neck of the bottle to the bottom of another bottle, and use insulating glue towrap a few more turns around the interface to make it firm.
4 Production of air plugs. Take a No. 4 soft rubber plug, use a drilling tool to make a straight hole slightly smaller than the valve core sleeve in the middle of the bottom of the rubber plug, then use a knife to cut off the thin end of the rubber plug. 'about 0.6 cm; cut the valve core. Put a larger "ring" on the sleeve (available at hardware stores), install the valve core from the thin end of the soft rubber plug upwards, put a similar "ring" on and tighten the screws. , just a little tight. Finally, use a whetstone to grind the air plug into a cylinder until it can fit completely into the mouth of the Coke bottle or be slightly tighter. Install the valve core and it can be used.
Production of 5 cannon heads. Take a rubber stoppersoft hock #3 and use a knife to sharpen it and make it smooth.
6 Assemble the wings. Take a bottle of Jianlibao and cut out a cylinder with two connected sides slightly longer than the length of the wings. Then use transparent glue and insulating glue to glue the four wings into four equal parts. Finally, place the cylinder with the wing stuck on it on the bottom of the water rocket so that it is level with the mouth of the bottle (this is not necessarily the best position, you can place it 'adjust up and down when practicing flying to find outside), wrap it with insulating glue and stick it firmly.
7 Others. In order to increase the contact area between the air cap and the bottle neck and increase the air pressure inside the bottle, you can use a knife to refine the big end of the cap of air and make it round, flat and rough. Being doSince the fuselage has a section added to constitute the rocket head, the rocket head is light and unbalanced. Paper can be stuffed inside to achieve balance. To minimize air resistance, glue the barrel head made of soft rubber plug to the bottle mouth of the rocket head with 502 glue.
Follow the method above to make a simple water rocket. According to the water rocket we developed, through practical improvements, it can fly up to about 160 meters in the horizontal direction and 40 to 50 meters in the vertical direction.
A power plant that uses the temperature difference between surface seawater (heat source) and deep seawater (cold source) to produce electricity is called a seawater temperature difference power plant.
Three basic conditions must be met to convertfiring thermal energy into mechanical energy: heat source, cold source and working fluid. Ordinary heat engines use water as the working fluid, and the heat source heats the working fluid to generate steam, which drives the turbogenerator to produce electricity. The exhaust steam is cooled by the condenser and the condensed water is returned to the boiler. continue to be heated and recycled. The thermal energy of the oceans comes mainly from solar energy. The world's oceans are vast and the tropical oceans are also quite large. Ocean thermal energy can be replenished after use and is worth developing and using. Seawater temperature difference power generation technology uses surface seawater (25-28℃) heated by solar energy as a high temperature heat source, and uses water sea (4-7℃) at a depth ofe 500-1000 meters as a low temperature heat source. high temperature heat source, using a thermal cycle composed of a heat engine. Power generation system technology. From a high temperature heat source to a low temperature heat source, it is possible to obtain efficient energy with a total temperature difference of approximately 15 to 20°C. Ultimately, it is possible to obtain energy with technical significance from a temperature difference of 11°C.
As long as half of the ocean surface, between 20° south latitude and 20° north latitude, is used for electricity generation, the sea water temperature does not will be only average. If the average temperature decreases by 1°C, 60 billion kilowatts of electrical energy can be obtained, which is equivalent to all the electrical energy currently produced in the world. Experts believe that the East Coast of the United States alone canobtain 75 times the electricity that the United States needed in 1980 thanks to the warm current coming from the Gulf of Mexico.
According to oceanographers' estimates, temperature differences in the world's oceans can generate up to 2 billion kilowatts of energy.
