Post processing tools for photos and videos are always a matter of subjective taste. After trying lots of different options, both Windows and Mac, I’ve settled in on Adobe Lightroom for photos and Avid Studio for video.
I’m using Lightroom’s library function to handle not only my photo archives but also raw video footage (which oftentimes is coming from either my Nikon DSLR or one of our point-and-shoot cameras).
I’ve started using Lightroom’s ‘virtual copy’ facility coupled with ‘Smart collections’ to easily manage photos with different aspect ratios for various purposes (web, email, video, print). Once I’ve processed the photo for exposure, color balance, sharpness, etc., I create virtual copies which can be cropped into the right shape and exported to the preferred size.
For pan-and-scan photo to video, I take care of all processing and cropping to video dimensions and aspect ratio inside Lightroom; then export the photos and raw video to a dedicated folder that I monitor inside Studio’s video editing environment.
Others may have a better workflow but this one is working pretty well for me so far.
