Technical controls are used to verify the assets compliance according to your businnes content guidelines. Different types of technical controls can be configured on the platform (dimensions, type of formats, codex, color space, etc.)
You can configure these requirements only as platform Administrator, see below an example of technical controls available for mp4 files:
These controls will be shown on the delivery request form and they are applied to every file uploaded by the Content Producer :

Here are some definitions that might be useful to create your first technical control:
Aspect ratio: is an image projection attribute that describes the proportional relationship between the width of an image and its height. For example, movies, which are usually shot with a wide-angle lens, have an aspect ratio that is typically 16:9, which means that the width of the image area is almost twice its height. The traditional television and computer display, on the other hand, are designed for an aspect ratio of 1.33:1, which means that the width of the display area is only 1.33 times the height, almost square. The inconsistency between movie and television aspect ratios has generally meant compromising the size or completeness of the image when you watch a movie on a standard TV set. Many newer television displays, such as those using HDTV technology, have a widescreen format with an aspect ratio of 16:9.
Color space: also known as "color model" or "color systems" is a specific organization of colors. In combination with physical device profiling, it allows for reproducible representations of color, in both analog and digital representations.
CMYK: is a scheme for combining primary pigments. The C stands for cyan (aqua), M stands for magenta (pink), Y for yellow, and K for Key.
The CMYK pigment model works like an "upside-down" version of the RGB: (red, green, and blue) color model. Many paint and draw programs can make use of either the RGB or the CMYK model. The RGB scheme is used mainly for computer displays, while the CMYK model is used for printed color illustrations (hard copy).
Media formats: The format of any computer file appears as the final letters of the file's name (following the dot), such as the VCD in MyMovie.VCD. This end label allows your computer to access the correct program to open the file; only then can you watch the movie or play the sound file. Media formats are used to store every audio and visual file your computer reads.

Audio and Video codecs: a codec – or coder/decoder – is an encoding tool that processes video and stores it in a stream of bytes. Codecs use algorithms to effectively shrink the size of the audio or video file, and then decompress it when needed. There are dozens of different types of codecs, and each uses a different technology in order to encode and shrink your video file for the intended application.
Frame rate: or "fps" in motion pictures, television, and in computer video displays, is the number of frames or images that are projected or displayed per second. Frame rates are used in synchronizing audio and pictures, whether film, television, or video.
Bitrate: is the number of bits that are conveyed or processed per unit of time.
Dots per inch (dpi): 1) In computers, dots per inch (dpi) is a measure of the sharpness (that is, the density of illuminated points) on a display screen. The dot pitch determines the absolute limit of the possible dots per inch. However, the displayed resolution of pixels (picture elements) that is set up for the display is usually not as fine as the dot pitch. The dots per inch for a given picture resolution will differ based on the overall screen size since the same number of pixels are being spread out over a different space. Some users prefer the term "pixels per inch (ppi)" as a measure of display image sharpness, reserving dpi for use with the print medium.
