I'd like to add a lens character to pre-recorded video. Video will come from a high quality camera and shoot, instead of a phone camera.
What's the best way to add a lens to pre-recorded video?
1) opening the raw file in manycam or camtwist. Ideally this is a 1080p 30p pro-res or h264 file.
2) running manycam/camtwist into snap camera on a computer
3) opening & recording the snap camera feed in VLC or OBS.
I've tried and this gives me lots of dropped frames. Any better ideas or solutions? Thanks!
