This would be very helpful to know because it affects the complexity of any recommendations. For example: I've been playing with a high resolution (1080p) ~30 FPS camera that writes insanely large files in .mov format to an internal micro-SD card. It has a built-in feature which automatically (and seamlessly) splits the data stream into 5 minute 'chunks' as it is recording. The files it creates in this mode are ~580 MB every five minutes. When the micro-SD card fills up, it continues uninterrupted recording by overwriting existing files, beginning with the oldest files first. To productively work with these large files, I learned that it helped a great deal to keep my "source", "target" and "system" disks isolated from one another to avoid device read/write contention. I frequently used cli ffmpeg to transcode these files into .mpg / .mp4 formats - the output format was determined by my use case - to make them much smaller and more manageable. cli ffmpeg is also convenient for exporting (transcoding) selected 'clips' by specifying the source 'start' and 'stop' times. Other times - again, depending upon the use case - I used cli mpgtx ("an MPeG ToolboX") to split large files down into equal sized 'chunks' to make them easier to work. In other words, I used a combination of tools and techniques to create and dump 'clips' into a source directory that I could use with whatever non-linear digital video editor I was experimenting with at the time. As for which editor I preferreed, Cinelerra is great but it has a fairly steep learning curve. I also liked kdenlive and openshot. hth & regards,
