Test #2 of my new stereoscopic rig - two cheap Canon VIXIA HF R400 camcorders sitting 2.5 inches apart (similar to our eyes) - was intended to be an internal microphone test, but along with me going through puberty again, a couple of birds tried to ruin this video.
However, since Janice is always preaching to me about turning bad situations into opportunities, let me tell you how you can sometimes salvage a mess like this...
According to my old Sync Shepherd, my stereoscopic degree of sync between the two cams was about 1/250th of a second, which I thought I could get away with, as long as birds didn't fly into the scene (ahem).
Now, here's where shooting 60fps can "almost" save some shots, and this is an old trick I used back in the old days before I monitored the sync (and it can even be accomplished shooting 60i, although deinterlacing adds some artifacts, so 60p is better for this kind of thing, which these new cams can shoot).
What I did during editing was set the project to 30fps instead of 60, then blend the frames, which literally "mushes together" all the information in the 60fps video(s). This blurred the wings of the bird, which makes the stereoscopic mis-sync less noticeable.
Obviously, as you can imagine, this method has some serious limitations, and won't work for all situations, but IMHO, in this video it saved me from reshooting a simple audio experiment.
