Granted I’m also talking about ending up with files with 30, kbps on purpose and then using Handbrake to cut the file size by half. Donna Peng HandBrake Resource. For my larger files, fiddling with the bitrate or RF values and the encoding process and speeds do make a difference. Matt Gadient February 23, Jeremy June 30, VideoProc is a multifunctional program integrated with video conversion, video editing, audio conversion, DVD conversion, video audio download, and video recording. Anonymous January 15,

Unlike HandBrake which can handle unencrypted discs only, VideoProc is available to convert both home-made and commercial copy-protected DVDs VideoProc currently doesn’t support Blu-rays. Anonymous April 3, Make to layers RF18 and RF 20 and keep on as normal and divide that through the other. I just never use that for this purpose because then I have to find the scene in the original to compare it. Possibly the biggest caveat for you is my primary usage of Handbrake is for rendering videos, not ripping. RF 24 is a suggested range.

You can skip to: Open Menu Close Menu. Many thanks to you, sir!

As to the original file size, the episode was slightly under 2GB. Note that you must click the appropriate buttons to watch this at full-screen p if you want to see the differences somewhat clearly:. I’m sure that setting the x preset to Very Slow, the H.

Handbrake: How do people calculate RF values?

Possibly the biggest caveat for you is my primary usage of Handbrake is for rendering videos, not ripping. RetroMetal Follow Forum Posts: She has written loads of articles to help people handle their DVDs, videos and other stuff. Chris February 22, This video is 35 MB and the compressed file is I ended up setting with bitrate conversions, because I can say, “This needs to be a high quality, I’ll set it to 4,” or “The quality is what it is, I’ll just go down to 2,”.


And you can probably go lower than those figures. If it’s high, it will degrade simpler scenes more than desired. Adan March 29, If I remember correctly, the quality spikes up really fast depending on the values, so going from 23 to 25 can be a huge jump, where you get videos with 40, kbps bitrate.

ViciousReiven Follow Forum Posts: Goldeneye January 20, Turns out my gig per 30 minutes was a bit over the top. Matt Gadient March 5, What RF value would I choose for this video?

Donna Peng HandBrake Resource. RF 0 means badly slow encoding while lossless compression. Note that these sizes ONLY apply to this episode of this source:. Let’s say you have a 2×2 array of pixels and each pixel is represented by one floating-point value e.

Fonstant Waung HandBrake Resource. You can use an alias and fake email. If your goal is to compress the video, then storing these values with full precision and fidelity will be more expensive than if you could store 4,2,1,8.

HandBrake: What’re the Best Constant Quality RF Value Settings for DVD, Blu-ray, HD/4K

The confusing thing is that, looking through old posts of mine, I was using RF 12, which actually reduced the file sizes of some of my Blu-ray copies. JJ March 30, Hey Peyton, The RF: HD videos have more pixels to begin with so each pixel can hold lesser information. Very slow, x tune: The scale is probably appropriate for the algorithm and the guts that’s running those conversions, but it feels like you quickly escalate the file size and bitrates when you mess with it.

You saying RF seems inconsistent is making me reconsider.


Comparing x264 “RF” settings in Handbrake (examples)

I did always compare the my compressed file with the raw, but I had no idea it could look even better. A group of pixels, say a 16×16 block, forms a larger part of an SD image than of a HD image, so it will play a larger role in the subjective visual perception of the image and have greater variation conwtantso you ought to smooth it out less.

When you use average bitrate, you can estimate the file size via a calculator but lose control over the quality. RF 51 means fast encoding while extremely low quality. Thanks Matt, as a newcomer to this stuff, that was very helpful.

They actually contribute to the correct contrast and brightness of the entire picture frame. Given the limitations of human vision, it turns out this is an acceptable compromise in the service of video compression. It just comes down to what quality you are comfortable with for one specific picture e.

For my larger files, fiddling with handvrake bitrate or RF values and the encoding process and speeds do make a difference. RF value is very roughly inversely proportional to “amount of useful information held in every pixel”.

It shows pretty well how bku bits have changed where. Constant quality RF value ranges from 51 to 0. For older grainier anime I use an RF of 16 and the grain tuning.
