Hi there, I have a makemkv rip of a bluray that is 35 GB. I would like a highish quality version but not so big to play on LAN, so I am using handbrake at it’s matroska H.265 1080p30 preset and the resultant filesize is only like 2 GB. I knew it would be a smaller filesize but does this seem right to you?
Doesn’t sound awfully wrong.
It’s worth to review what the preset does – some of those default presets will not only transcode the video but also drop surround sound in favor of a stereo re-encode of the audio tracks (maybe dropping multiple audio tracks from the source). On a blu-ray rip, that can already account for a noticeable share of the file size.
The Blu-Ray source material will usually already have a modern encoding (contrary to DVD material which usually comes in MPEG2).
Blu-Ray rips shouldn’t be a problem to stream over a wired local network… depending on its duration, the 35 GB file might stream at 30-40 Mbps.
For sure, i have a gigabit LAN, its more that 35gig rips tears through my storage in a hurry and NAS drive prices arent getting any cheaper.
I have the audio passed through. Just seemed crazy that it could eliminate 33 gigs and come out looking about the same.
If you want to retain a high quality, dial down the “encoding speed” to slow.
This does not only activate quality-preserving features of the H.265 codec, but does also tell the encoder to try harder to find the most space-efficient encoding strategy for any scene. The price you pay for this is encoding time.
I am talking about software encoding [“Video Encoder” set to “H.265 (x265)”].
Using “NVEnc” or “Intel QSV” will use hardware transcoders, which will give you neither top-notch quality, nor the best file size reductions. Their pro is processing time and lower power consumption.
(Though for some applications, like daily shows which are watched once then deleted it might be perfectly adequate.)
The resulting file size is also dependent on the source material. Videos with a high amount of grain/noise, or fast/extensive camera movements, or rapidly changing picture content cosume more space.
So your original question can only be answered with “it depends”.
