In the past, QuickTime (Pro?) was excellent for this sort of thing; you could just mark the section you wanted right in the player window and export a new clip. I don't know what the present situation is with QuickTime, and obviously that's an Apple solution. There are basically two classes of editors: * "pro" editors, like Premier, and (old?) Final Cut Pro * "home" editors, like iMovie, Windows Movie Maker, OpenShot etc. You want something from the latter category. The general idea is: 1) Add your source video file to a new project 2) Drag that video onto your timeline 3) Edit the timeline to crop your video (various methods depending on user preference) 4) Export your new clip You haven't mentioned your platform, so lets give a simple example using the free, cross-platform OpenShot: 1) Add your source video file to a new project 2) Drag that video onto your timeline 3) Grab the edges of your video clip in the timeline, and drag them to crop your video 4) Export your new clip Short YouTube video (not mine) demonstrating this visually (you don't actually need to select the razor tool): https://www.youtube.com/watch?v=P8zmqfXXS60 https://www.youtube.com/watch?v=P8zmqfXXS60 --- Is this an easy enough method? I think to get any easier than that, you may be looking at a purpose-built tool to do only the simple thing you want, rather than a general purpose editing tool. --- edit: I didn't see your file format requirement. I honestly don't know anything about .gifv; it appears to not actually be a file format at all, but some tomfoolery that Imgur is engaging in? You'll have to export to an actual video format (say webm or mp4) and figure it out from there.
