Anirban,

Right click on your object and pick 'Video effects' >> 'Save video effects...'. You get the option to pick which of those applied to save and then need to pick a sensible file name so that you can find it again -- the default name is the file name of the object. To apply to a new object select it and do 'Video effects' >> 'Load video effects'.

Notes:

• If you have applied key frames the effect will be listed as 'dynamically'
• There is an option on the key frame window to 'Combine effect curve with object length' for each effect which is useful if say you want a zoom in of 25% of the clip length rather than a fixed number of seconds

Regards,

Carl
