My camcorder puts out AVCHD files. So if they are imported to CS5, are then compressed in mpeg 4 when a rendered file is made? Someone told me that elements and premiere pro cs5 do this?
As far as I know, PPro and PreEl do not output AVCHD... so, yes, editing AVCHD and outputting does result in compressing to another codec
AVCHD direct to BluRay http://forums.adobe.com/message/2785066?tstart=0AND a possible workaround http://forums.adobe.com/thread/706465?tstart=0
You really need to read up on Exporting a movie. (and compression)
eg. You can export lossless (no added compression) if you wish ....or you can export with a ton of compression.
Its up to you and the requirements of your deliverable.
