Basic plug-in questions

hello all.  i'm getting started writing ae plug-ins.  i;ve lloked through sdk manual , built couple of sample projects. 

 

i have basic questions plug-ins:

 

if want plug-in work ae cs5 , cs6, can build cs5 sdk, or need buiild 2nd version using cs6 sdk?

 

once have working plug-in on windows, how work required working on mac?

 

how decide if should write aegp or effect plug-in?  if plug-in works multiple layers in composition, i'm thinking should aegp rather effect, right?

 

regards,

 

jeff

i didn't swith cs6 yet, can tell sure,

but know, plug-ins created cs5 sdk should work cs6.

only few require minor adjustments. (probably avoiding deprecated suites)

 

as switching mac:

unless used specific os api, 1 of very few api fcuntions specific mac or pc (such get_main_whnd()), should same code mac/pc.

on mac sdk, duplicate existing project, did on pc, , copy code.

 

effects vs aegps:

effects placed on layer, input , output buffers, , (should) process video , audio. effects can access image data other layers. (look @ "checkout" sample see how)

aegps else. not placed on layers, loaded once when ae boots, , live thoughout session. can access video sources, not automatically called upon render specific layer.

so, if color corrector? it's effect.

is new formant importer? it's aegp.
