Description


Fast & Nimble Screen RecordingViking Screen Recorder is a full-featured screen recording app for Mac OS X. It features a high performance screen capture facility, as well as a built-in video editor and video player that supports all popular video formats.Just like a Viking -- this screen recorder takes whatever it sees and doesn't tolerate any loss.  As such, we have incorporated a "Lossless encoding" mode that uses the FFV1 codec (provided by the FFmpeg project) for 100% lossless, pixel-perfect frames.  This codec is used by professionals for video archiving, so you know it's serious business.And also just like a Viking longship -- this app is fast and nimble.Of course, lossless encoding doesn't come without a cost, and as such, you pay the iron price (or in your case, silicon) -- lossless encoding does take up disk space.But -- fear not!  We also included the requisite H264 encoding mode that all popular screen recording apps come bundled with to produce standard highly compressed (but still very high quality) .MOV files.On top of that, we support the advanced Apple ProRes 4444 and 422 formats.As a bonus, we threw in a GIF encoding mode for free (no sound, of course).  This mode allows you to record your screens and upload them to places like Reddit.  We can have nice things!ABBREVIATED FEATURE LIST:------------------------------ Support for H.264, Apple ProRes 4444 & 422, MJPEG, FFV1, and GIF formats- Features a built-in video editor and player!- Crop, resize, rescale, trim your videos.
