+# Action cam footage batch stabilization script
+Out in the wild, you can only carry too many Gopro batteries and you can never
+be sure when you can charge them. You can extend battery life by turning off
+stabilization, which is quite battery intensive. But the problem is that you
+have to post process the footage when you get back to the civilization. Footage
+taken without stabilization on is generally unusable because it's too "shaky".
+
+The post process can take a very long time depending on the amount of footage
+you took. Gyroflow is a great tool, but it was not made by Unix programmers so
+it has poor CUI and scripting support.
+
+Actions cams like Gopro produce what's called "low resolution video"(LRV) files
+in addition to the actual footage on the fly by default. These LRV files are for
+on-device playback and "proxy clips" in video editor software. LRV files need to
+be regenerated as well for good editing experience.
+
+It seemed obvious that I messed up and had to come up with a solution. At first,
+Makefile seemed like a good straightforward answer, but the way Gyroflow was
+designed made it impossible to incorporate it. So naturally, I ended up writing
+the Python script.
+
+## The script
+The script had to be reentrant because the VAAPI support on Linux isn't quite
+there yet. The driver can crash the window manager at any given moment, the
+external USB hard drive can pop out any time due to insufficient power and so
+on. The script had to be resilient to hardware failures.
+
+Gyroflow and FFmpeg outputs files suffixed with ".tmp.mp4". After a successful
+run, the ".tmp" suffix is removed. Upon reentry, they're simply overwritten.
+
+On startup, the script looks for all .mp4 files that are **NOT** suffixed with
+".tmp" or "_stabilized" to skip the files that are already processed from the
+previous run.

+Stabilize all action cam(Gopro) footage in the current working directory using
+Gyroflow, produce low resolution video(LRV) files using FFmpeg.
+
+NOTE: Gyroflow requires hardware acceleration, which may require a non-free
+version of mesa driver depending on the VGA on your system.
