My camcorder produces huge MOV files, and I use it for about 1 hour every day, which gives me more than 7 GB of data per day (around 128 MB per minute of recording). Here is the codec information given by
ffmpeg -i for a sample 12 minute clip:
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'Video.MOV': Metadata: major_brand : qt minor_version : 0 compatible_brands: qt creation_time : 2013-02-05 20:12:47 original_format : NVT-IM original_format-eng: NVT-IM comment : CarDV-TURNKEY comment-eng : CarDV-TURNKEY Duration: 00:12:37.00, start: 0.000000, bitrate: 15935 kb/s Stream #0:0(eng): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 1920x1080, 14745 kb/s, 30 fps, 30 tbr, 30k tbn, 60k tbc (default) Metadata: creation_time : 2016-02-05 20:12:47 handler_name : DataHandler encoder : h264 Stream #0:1(eng): Audio: pcm_s16le (sowt / 0x74776F73), 32000 Hz, 1 channels, s16, 512 kb/s (default) Metadata: creation_time : 2015-02-05 20:12:47 handler_name : DataHandler
These are files I would like to keep, and in a decent quality. I will not have storage enough to keep them all in the long term, and my country is one of the most expensive places (if not the most) to purchase or import hardware components, so buying new hard drives is really out of the question.
I have tried recompressing this 12 minute clip using different settings on Handbrake (including of course, the Normal and High profiles), but the resulting file is generally the same size, if not bigger (around 1.5 GB).
I have searched on YouTube for HD videos, and have downloaded a few videos just to check their size, and I got 1080p 12 minute clips for around 200-300 MB in size. They may have reduced some quality, but in my eyes, 1080p videos on YouTube generally look pretty sharp. If possible, I would like similar results!
While searching here on Video Production, I have found this answer which says that "cameras have to compress on-the-fly, so they use constrained baseline mode (...) if you'd like to recover some space, you can use ffmpeg". I have tried running that particular command, but still I am getting huge files.
I am on Linux, but could maybe run Windows in a virtual machine too.
