Our camera club uses this very capable software. Our image handlers send images away to be judged. The judges record audio, which the image handler syncs with the images for viewing at our meetings. Recording the slideshow as video does degrade the image quality, so I only did it as a back up.
It was my experience that computer resources needed increased with the number of images and length of audio. Eventually I handed off the job to someone with a better computer. If a trial version is available, check to ensure the computer you own is powerful enough to do the job.
