iii. Colour (e.g. specific colours for a specific channel, programme, department or to ensure visibility)

v. Resolution
Typography
The font on idents must appeal to all viewers, however, this is a limitation because the person who is making the ident can only go to a certain extent as to how large or small the font can be for the ident. Another reason is also the font for the ident, this can also be a major limitation because some creators may wish to use fonts which cannot be read by everyone. In the example below of Comedy Central, the font of this ident is a basic size, however, everyone may not be able to read it, as it does not appeal to everyone.
Size
The size for idents is critical, however it varies. One example is the channel having the ident and also trying to squeeze in the scheduling. This can be a limitation because size is the most important thing when it comes to idents, as it has to be visible and clear for the audience to see. Another example is the logo being too big on screen for the ident, as positioning of the logo is important.
Colour
Colours are a major limitation when it comes to idents because saturated colours tend to bleed in the idents. Safe colours are the broadcast colours which are under 235 (such as red, green and blue.). This is a limitation because it doesn't allow the creator to use colours they wish. Bright colours can create an electrical disturbance. The example below explains and also shows how colours can become saturated and bleed into the idents. Another example is MTV, they use bright colours to appeal to their target audience, which is 12-34 year olds.
Colour can also become a limitation when used by other channels because certain colours may already be used by existing broadcasting channels, so this means that channels have to be branded by specific colours used, such as their logo colour will be based around the colours of the ident. The colour pink, can be a limitation when making idents because male viewers may react negatively because of the fact that pink is a feminine colour, and the channel may be for women. This relates to
M you must explain how it relates to communicating visual ideas to a non visual audience and appealing to them also.
Aspect-Ratio
Aspect Ratio is a limitation when it comes to idents because if you don't get the right aspect ratio, it will ruin the footage with black boarders as it will cause stretching and make the ident look bad. Another reason is that the aspect ratio must be precise so that the creators can know how much content they can fit into the ident.
4:3 - old, but common, used on standard television screens such as a box tv.
16:9 - standard, more natural ratio which is used on YouTube, phones and LED TV's
21:9 - used in films, high quality cameras and super high screens.
When an ident is created, the ratio is chosen, if the ratio for the display is wrong, then the the ident will get cut off. So in order to prevent this, the ratio for the ident must be designed to fit the suitability of the most common ratio of where it will be most popularly used.
Resolution
The resolution of idents is also a limitation because if the resolution is poor, for example: 144p, it will become pixelated.
720p is HD.
1080p is the HD standard for resolution in videos.
The quality of the ident must look correct on all resolutions, as they cannot look poor on a low resolution and stretched on a high resolution. A limitation of this is that if the resolution is low, it will be difficult for viewers to see what is going on, so it is a necessity to have a high definition standard in their videos.
Below is the resolutions of the quality of the 20th Century Fox ident , from 144p to 1080p.
