They won't tell you much and aren't usually representative. As you can now compare both file sizes and image quality differences you can also better gauge the approximate final file size of your encode. Run test encodes on each clip and compare your encodes with the source files. Use an MKV splitter to extract ten one minute sample clips. Use MakeMKV and rip each Blu-ray to create an MKV source file. Running test encodes is the best way to assess the end result, without encoding the whole film. Films vary widely in how they encode (film grain, action etc) and using the same RF value will often lead to either too large an encode file or too low a bit rate. Its job is NOT to reduce file size (that's an off-shoot). It’s important to remember Constant Quality encoding has one task, to reach the image quality level you have set, RF17, 21 etc. If you want a much better balance between image quality and file size then you have to put in some work, one RF setting will not suit all films. Some films will need a higher bit rate than RF21 affords them. If image quality matters, but file size is also important, then for H.264 encoding use Super HQ 1080p30 Surround Preset and set Constant Quality to RF21. But these settings for me produce a smooth, stutter free experience even underclocked at 800MHz. Note, for some films this will create encode files well over 20GB. 'Mobile DVD or BD' will now be saved as a preset and listed on the right hand side in Handbrake to be used in the future Step V: Convert the video and copy to your Mobile Device Some people may be using different settings and thats fine. If image quality is everything and file size is not a factor, then for H.264 encoding use Super HQ 1080p30 Surround Preset and set Constant Quality to RF17. Oct 2017 Hello All, My file details are as follows: General ID : 0 (0x0) Complete name : E:\house Islo Sept 2017.m2ts Format : BDAV Format/Info : Blu-ray Video File size : 3.77 GiB Duration : 21 min 45 s Overall bit rate mode : Variable Overall bit rate : 24.8 Mb/s Maximum Overall bit rate : 28. If you want a set and forget approach you have to be tolerant of potentially large files or conversely lower image quality.
