Enhancing Image Processing in Multimedia Module: Quality and Format Challenges

This project explores the discrepancies in image quality resulting from different processing methods within the Multimedia Module. It addresses issues such as the insufficient support for grainy formats like CMYK and JPEG 2000, and incorrect mapping of EXIF metadata. We also analyze the impact of scaling and compression routines on the visual output. Further challenges include unresponsive resolution tabs, preview delays with high-resolution images, and cluttered dialogue boxes. The goal is to streamline image handling while expanding compatibility with various multimedia formats, including video and text.

Presentation Transcript

  1. Project Opal Multimedia Module

  2. Image quality • Difference in quality between image processing of pre-load image derivatives to the auto generate derivatives in the Multimedia Module. • Appears to be different scaling and compression routines.

  3. 3230 Multimedia Tab - Grainy

  4. Formats / Types not supported • CMYK • 16 bit • JPEG 2000 • EXIF metadata

  5. Incorrect mapping to current MM fields • Resolutions tab • Compression displays JPEG colour mode tag instead of the compression setting • Characteristics tab • Does not read or reflect the resolution of the image, ie tiff or jpeg

  6. Resolutions Tab

  7. Characteristics Tab

  8. Whose window? • Cannot expand the dialogue box to see the complete file name. • Preview on default - long wait for high resolution images before they can be selected. Will always default to preview on even after user has turned it off.

  9. File name length and preview in Multimedia Add

  10. Workaround for high resolution images • Tucked in via second add function on resolutions tab • Do not want these on the top of the table • Reports call upon these images • Tuck-in function appends the NMA file name with a duplication of the name

  11. ‘Tucked In’ and duplicated file names

  12. Additional formats • Video • Audio • Interactive media • Text • PDF • etc
