Abstract

A method and apparatus for preparing an image for downloading over a link. The method includes receiving a user selection for an image to prepare, retrieving current user settings reflective of desired settings for compressing the image and automatically presenting a plurality of variations of the image to the user where each variation is derived using compression settings that are scaled from the current user settings.

Claims

1. A system for preparing a file for downloading over a link, the system comprising:

one or more processors; and

a computer-readable storage device, comprising instructions operable to cause the one or more processors to perform operations comprising;

receiving a selection for a file to prepare for downloading over a link;

retrieving current settings reflective of desired settings for compressing the file, the current settings defining a first compressed file size for the file;

automatically deriving alternative compression settings, the alternative compression settings including compression settings scaled from the current settings and defining alternative compressed file sizes for the file, the alternative compressed file sizes being different from the first compressed file size; and

substantially simultaneously presenting to a user a plurality of variations of the file where at least one variation is generated using the current settings and at least one variation is generated using one or more of the alternative compression settings that define the alternative compressed file sizes of the variation.

2. The system of claim 1, further including estimating for each variation of the file a respective amount of time required to download the variation to the user where the estimated time is calculated from an assumed transmission rate of the link and a compressed file size defined for the variation.

3. The system of claim 2, where the respective estimated download time is presented along with each variation of the file.

4. The system of claim 1, wherein the file is a video file.

5. The system of claim 1, wherein the step of presenting a plurality of variations includes receiving a selection that defines a number of variations that are to be presented to the user and generating the number of variations selected.

6. The system of claim 5, further comprising adjusting the scaling from the current settings for each variation depending on the number of variations that are to be presented.

7. The system of claim 1, wherein the step of presenting a plurality of variations of the file includes presenting the file at current defined compression settings along with three variations generated using the alternative compression settings.

8. The system of claim 1, wherein a first set of alternative compression settings is derived by scaling from the current settings and a second set of alternative compression settings is derived by scaling from the first set of alternative compression settings.

9. The system of claim 1, further comprising receiving modifications to the current settings and generating a variation of the file using the modified settings.

10. The system of claim 9, further including recalculating compression settings for each presented variation of the file using the modified settings and re-generating each variation using the recalculated compression settings.

11. The system of claim 1, wherein the current settings define a first quality of the file and each variation generated using the alternative compression settings has a different quality relative to the first quality.

12. The system of claim 1, wherein:

substantially simultaneously presenting the plurality of variations includes presenting information related to a compressed file size of each variation.

13. A system for preparing a file for downloading over a link, the system comprising:

one or more processors; and

a computer-readable storage device, comprising instructions operable to cause the one or more processors to perform the following operations;

receiving one or more compression settings for compressing the file and a number specifying how many variations of the file are to be generated, the received compression settings defining a first compressed file size for the file;

automatically deriving a plurality of alternative compression settings that are different from the received compression settings and define alternative compressed file sizes for the file, the alternative compressed file sizes being different from the first compressed file size;

using the derived alternative compression settings to generate at least one variation that has an alternative compressed file size in a plurality of variations of the file, the plurality of variations including as many variations as specified by the received number; and

substantially simultaneously presenting two or more of the plurality of variations of the file.

14. The system of claim 13, wherein:

automatically deriving a plurality of alternative compression settings includes deriving one or more alternative compression settings based on the received compression settings.

15. The system of claim 14, wherein:

deriving one or more alternative compression settings based on the received compression settings includes scaling the received compression settings.

16. The system of claim 13, wherein:

receiving one or more compression settings includes receiving one or more compression settings based on input.

17. The system of claim 13, further comprising:

generating a variation in the plurality of variations of the file using the received compression settings.

18. The system of claim 13, wherein the file is a video file.
