“Read this post:

Samsung Galaxy and S7 video footage !”

There is no link there ☹

Anyway, thank you, everyone, for your help. I used Adobe Media Encoder and changed the files to 23.976 fps to match the Canon 7D footage and now the stuttering is gone, although the audio is slightly out of sync. All footage from all sources was recorded at 48k, so I don’t know why it’s out of sync. But it doesn’t drift — it’s just off by a few frames, so I can easily adjust.

What a pain! I sent an email to Filmic Pro support — maybe they have a workaround for the future.
