looks pretty easy with ffmpeg too if you're feeling all command line and not wanting to install extra stuff... https://www.markbuckler.com/post/cutting-ffmpeg/ This is that dude's easiest method, if key frames work for you:
Key Frame Seeking The fastest way to extract a portion of video from a larger video (with a 60 second clip starting 30 seconds in) would be the following: ffmpeg -ss 30 -i input_vid.mp4 -t 60 -c copy output_clip.mp4 This method is so fast because it uses Key frames when performing seek, and there are far fewer Key frames than Predicted frames. It also is a stream copy <https://ffmpeg.org/ffmpeg.html#Stream-copy> meaning that the encoded data extracted from the original video is taken directly without decoding and then re-encoding. While this feature may be useful for some users who don’t care about frame accuracy, it doesn’t work for our purposes. This is because even though FFmpeg 2.1 enabled frame accurate Key frame seeking for frame extraction (more detail here <https://trac.ffmpeg.org/wiki/Seeking>) this behavior is not supported in FFmpeg 2.6 when cutting out clips of video. This means that the start of your video will be aligned with the nearest Key frame to 30 seconds, not the nearest frame independent of encoding format.
