Because film companies are in the Media industry most of the Idents that we see at the beginning of films are quite often animated. A little jingle is added which makes the Ident more memorable and recognisable for the audiences.
The purpose of an Ident is for a film company to show their audience that they were involved in the production/making of the film, its a chance to make themselves known. Audiences who watch the film will recognise the jingles on an Ident because they are catchy and captivating and will know instantly who the company is that's involved without knowing, because its catchy.
Above is a screenshot of the images that came up when I Googled 'Ferris Wheel' as I knew that is the sort of image I wanted for my Ident.
In Final Cut Pro I added different effects to the image, I changed the colour and the contrast and added a faded fuzzy effect. I chose how long I wanted the Ident to last and when I wanted the jingle to come in with the writing of the company name. I called my company 'Wonderland Pictures' because it was a nice name that's simple to remember.
