Another interesting survey.
On a youtube talk forum, a straw count was taken asking users what their favorite editing software was (NLE). Out of a sample size of 104 this is how it broke down below (I added my preferences as well, premiere pro and screenflow)
23% Sony Vegas Pro
23% Premiere Pro
13% Windows Movie Maker
8% Final Cut Pro X
6% iMovie
4% Camtasia Studio
4% Corel Video Studio
3% VideoPad
2% Lightworks
2% Magic Movie Edit Pro
2% HitFilm
2% Power Director Pro
2% ScreenFlow
1% Sony Movie Studio
1% Kdenlive (Linux)
1% Filmora
1% ffmpeg
1% VirtualDub
1% AVS Editor
1% VideoStudio
Notable mentions:
1, Avid, 1 person mentioned it, but they were forced to use it in a university program, otherwise at home, for actual video editing work they used another tool. So I left it out since it was not exactly a glowing endorsement.
2, Davinci Resolve, another surprise. A wonderful free program that came out when black magic 4K video camera came out. But no-one in the youtube community is using it yet. Actually I use premiere pro myself, but still thought more people would be using this one.
