VideoCalc is The tool that will help you design Home Theaters in a consistent, quick and easy way. It makes all the tedious calculations a breeze and ensures you can get the desired information in an intuitive way. This is a must have for Home Theater enthusiasts, custom installers, video professionals and more. VideoCalc is made up of several tools, that each in its own right provide you with essential calculations but do work together, ensuring the effect of every component on the system is taken into account. Furthermore the tools are organized in a natural progression, guiding you through the process of designing a Home Theater that follows the industry best practices and standards. Start by defining your screen. The tool allows easy calculation of any screen dimension based on the others. Support for usual aspect ratios is provided, allowing you to pick amongst a selection of the most commonly used aspects. For a projection system, the next step tackles the projector part, defining the aspect ratio of the matrix and the optional usage of an anamorphic lens. The tool shows you how the image will fit within the defined screen and the deformation that the anamorphic lens would apply to the projected image. This is also a fantastic tutorial tool to understand anamorphic systems. The next step takes care of projector placement and/or selection in regards to the throw ratio requirements. Enter the throw ratio range of your projector and check it can be placed to work with your screen. Alternatively, enter the distance from the screen where you wish to place your projector and the tool computes the required throw ratio. This is perfect for selecting your lens on higher-end projectors. The Luminance tab allows to find out how big the screen can be with a given projector or how bright your projector must be to light up the defined screen, while respecting the industry best practices. With the Angle tab, validate that your field of view is in accordance with industry accepted standards such as THX or SMPTE. VideoCalc works in both imperial and metric units. Simply swipe down to reveal the unit selection view, giving you the choice between centimeters, meters, inches and feet.

"Video Size Calculator" is a useful tool that will calculate the approximate file capacity after creating video easily. [Feature] The main frame size and frame rate can be calculated quickly because it is registered in the tab. Custom sizes can also be calculated by any numerical input. Calculated capacity is GB, MB, KB, can change the bytes and the unit does not need to be calculated each time. [How to use] 1. Choose from, such as full high-definition and DVD size. 2. The total time of the video, hour, minute, second input and respectively. 3. Select the FPS (frames displayed per second). 4. Calculate the approximate capacity and press the "Calculate" button. 5. The approximate file capacity was calculated switching in arbitrary units to confirm. Attention: In the case of bit rate calculation is calculated to enter a number from the time you turned on the switch. Please press again "Calculate" button if you want to change the number or tab recalculation. Please understand that only an approximate file capacity. The capacity of the sound source is not included.
