HA4 - Task 3 First Evaluation

For this task I had to look at video format, screen resolution, frame rate, screen ratio, codec’s and graphics of four different stop motions and compare them all to each other.
All the different motion graphics I looked at and researched are all very different. I watched them and found them all on YouTube but tried to find out all the technical comments for the original format of the motion graphic also. The first one I researched and evaluated was the Grease Film Opening which is a very old film so the opening was completely different compared to the newer graphics, pixels, video format and resolution like a film now. The format of the video wasn’t in HD and I checked this on the DVD, however the Finding Nemo Interactive Menu which was the second stop motion I researched was in HD on YouTube and on the DVD, which I watched. The film was released on DVD on September 24 2002 for the first time. When DVD’s were released in 2002 a new codec came in which was AVC/H.264, this was the codec for the Grease film opening. Even though this film was released in 2002 the original film and formats were made when it was first filmed in 1978 June 16th. The frame rate of this film was 29.97 fps which is good for the time of release but the technical parts were updated when it was re released. Because this film isn’t in high definition that means its standard definition so the resolution off this film should be around 640*480 but I couldn’t find the exact resolution.

Finding Nemo was released just the year after Grease on the 30th May 2003 so some as well as it being animation it was also a year more advanced so the two films look completely different. The definition, resolution and the video both look and are different. I have found some of the technical comments for the YouTube video I viewed it on and for the DVD I watched it on. MPEG4 is the codec used for the YouTube video of the DVD Menu its good because it shows good image quality. The frame rate for the DVD is 23.976 fps which is one of the higher frame rates; this is used to give the film a heightened sense of reality for the viewers making the film look very good. Even though images seem to flicker if they are lower than 30fps but the human vision has no frame rate. The resolution for the interactive menu 1280*720 and that’s what the whole film is in as well. However on the YouTube video I watched it on the resolution was 240*240 which is clearly much smaller.

The E4 sting was my next research and this is the most modern one released onto YouTube 1st Feb 2012 this was shown in HD and you can see the difference between the animations on the Grease Opening to the Finding Nemo Interactive Menu. This stop motion looks very real like someone’s moving the toy soldiers because of how they move which looks more robotic which is the style they was looking to make. The frame rate of this sting is 25fps which is in-between the other two stop motions, however you can’t really tell because this sting looks fast because of the short amount of time it’s on for and what’s going on in the animation. The video format for this stop motion is HD this is because of how short it so they need it too look good and catch viewers eye, compared to the others that are films so are much longer. The resolution for most E4 stings including this one is 1280*720 which the same as the Finding Nemo Film DVD whereas the YouTube video I watched the sting on is 240*240 so much smaller to fit to the website. If a screen resolution is 1280*720 like the E4 Sting and Finding Nemo Interactive menu then the stop motion is High Definition.

The last stop motion I looked at and researched was the Wallace and Gromit BBC One ident. This stop motion used a lot of animation like the Finding Nemo interactive menu and E4 Sting. However in this ident the characters used are made from moulded plasticine modelling clay so this would have taken longer to make than the other animations. The resolution for the YouTube video I watched it on was 240*240 like all the other YouTube I did research on. If I had watched it on the TV this stop motion would have been HD but the resolution is made smaller specifically so it can be shown on YouTube.

Look at pros and cons of the different codec’s for each thing.
