Since I got a dashboard camera for use in my car I have got very long videos which I would like to split into smaller parts. What can opensuse offer me for such a job? And if I start editing, what are the programs of choice?
Hi Constant,
We don't know the camera make & model or the recording format it uses. 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,
Dear Carl,
Am still finding out the specifics of this gift but in the mean time I know that the picture format is .MOV. Have already reuced some videos to .mp4 for a smoother playing. Will now dive into editing. Thanks list for the help
