Lecture9 finalfinal2011
A digital cromalin provides the best color matching for printers as it is calibrated to show CMYK colors exactly as they will appear in printed inks. It is an industry standard proof used by printers to ensure accurate color matching between proofs and printed materials. Press proofs of materials printed on newsprint are especially important, as newsprint absorbs more ink and prints darker, requiring color adjustments. Pre-production in film involves organizing all aspects of production such as budget, cast, crew, locations, and scripts before filming begins. Post-production includes editing, sound, visual effects, and other processes that occur after filming is complete.
Technical report
Frame rate refers to the number of consecutive images or frames displayed per second in a movie or video. Films are typically shot at 24-30 frames per second, while some newer movies use 48 frames per second for higher quality. The appropriate frame rate depends on the genre and whether it will be viewed in theaters. Video format refers to the type of file the video is saved as on a computer so it can be edited. Common screen ratios for movies and TV include 16:9 and 4:3. Resolution refers to the number of pixels in an image, with higher resolutions allowing for larger displays and more detail. Compression reduces the file size of audio and video by decreasing volume differences to allow for broadcasting and storage.
Post production process
Post-production is not a troublesome procedure. There will be no hectic calendar of working for 14 - 18 hours like the creation procedure which incorporates a great deal of work. The main thing to do after the creation procedure is finished, is to call your cinematographer so he can acquaint you with various editors. All you need to do next is enlist some great individuals and watch out for their work day by day for a hour or somewhere in the vicinity. The creation procedure will be simple for you in the event that you tail it well ordered.

The graphic is an ident for Channel 4 that uses movement of vehicles and the camera to draw attention. It shows cars driving down a busy city street from the perspective of a camera moving backwards under bridges. It eventually reveals a large number "4" made of building parts in the sky. The only technique used is movement to keep the graphic constantly moving and engage viewers. It is in PAL format with standard definition and a frame rate of 25 fps using Xvid compression.

Video format refers to the technical specifications of a video, including its resolution, screen ratio, frame rate, and whether it is standard definition (SD) or high definition (HD). SD videos have lower quality but will play smoothly on more devices, while HD provides clearer quality but requires sufficient internet bandwidth and hardware. When uploading videos to YouTube, the document recommends using HD format, MPEG-4 compression, and a 16:9 screen ratio for the best viewing experience. Frame rates of 30-60 fps are supported by YouTube depending on a user's computer and internet connection.

The document discusses various topics related to digital images, including:
1. Image resolution, which refers to the detail an image holds and can be measured in lines per unit or angular subtenant.
2. The difference between vector and raster graphics, with raster images composed of pixels and vector images composed of paths, allowing vector images to scale without losing quality.
3. Common file formats like TIFF, PNG, GIF, JPG, and their uses, strengths, and limitations, such as GIF and JPG being primarily used for web images currently.

The technology of editing
- 1. The Technology of editing
- 2. The more expensive the camera the better quality of the film. IMAX film is regarded as the best possible quality however there is still a disagreement of which is better.
- 3. Film Size • The picture quality (resolution) turns out better depending on the wideness of the film in mm.
- 4. Digital Resolution Digital quality is measured in pixels.
- 5. Aspect Ratio Aspect Ratio is how wide the screen is so the relationship between its width and its height.
- 6. Standard Definition vs High Definition -Standard Definition is lower then HD -Either 4:3 or 16:9 aspect ratio -DV PAL is a SD format- we use it lots.
- 8. Formats The type of file you use to export something for example on to Youtube.
- 9. The right digital formats The right digital formats are important to maintain good quality.
- 10. Online editing - online editing uses the highest quality to edit.
- 11. Offline editing • Offline editing is part of the post production process, which used to be used more, it import the footage at a lower level of quality.
- 12. Linear editing Linear editing is film from a camera so editing of 2D images.
- 13. Non linear Digital video editing is no linear
- 14. Tapes vs hard discs Hard discs are quicker because its all digital and tapes could tare away eventually because they are fragile and working with tapes is a lot more complicated because you have to use wires which go into the computer but with hard discs which is just a simple disc that goes into the computer.
Editor's Notes
- There is a still a debate about what is best. I would agree that IMAX is better
- Theres load of different types of film, the most common film still in use today is 35 ml with the largest at imax film being 70 mil
- Digital Quality is measured so if you got a magnifying glass you would be able to see thousands of pixels and the more pixels the better the quality
- Standard definition pictures are still broadcast on tv that because you can fit lots of standard definition pictures in the same space as one high definition
- To take captive as by force or craft.
- Consumers use this to encode videos.
- Editors need to choose the right format to get the best quality and the best file to explore it in the end.
- Online editing is the most common because computers are powerful enough
- anything higher then the high definition is usefully offline
- Linear editing is a lot more work as it involves cutting the film or tape and if you make a mistake you have to start all over again,
