    Slice Videos with ffmpeg

    Isolating a specified portion of a video is a very common task for those who work within the media, probably using nice GUI tools to slice clips from the full video.  I'm a developer, however, and know how amazing ffmpeg is so I prefer to do my basic video slicing from command...

    How to Watermark Images and Videos

    As a content creator I respect an author or artist's desire to protect their work.  I don't consider this blog art but I'm annoyed as hell when I see my blog posts show up on another site.  I'm lucky enough that my blog is mostly recreational but many...

    Access Mac Camera by Command Line

    With all of my recent command line tutorials, I've really gotten excited about the shell's simplicity and realized the true power of using the underlying technology of pretty UIs.  Since I work from home, I spend a lot of time on video calls, so when...

    Create an Image Preview from a Video

    Visuals are everything when it comes to media.  When I'm trying to decide whether to watch a video on Netflix, it would be awesome to see a trailer of some kind, but alas that isn't available.  When I'm looking to download a video on my computer...
