Re: RF and File Size

Yeah I expect that movie to movie quality will vary. Thing is I want to store a bunch of movies on my laptop computer's SSD and I don't have a huge amount of space on that drive. I want movie files to be more on the smaller side without getting too much visual loss. I end up doing trial and error wi...

Re: RF and File Size

Okay, thanks for the replies people. It sounds like 2 pass Average Bit rate is what I'm looking for. If quality holds fairly constant from frame to frame I'll be good with that. I just didn't want to have quality go way down for higher bitrate sections of the video compared to lower bitrate sections.

Re: RF and File Size

For the same output bitrate, 2-pass average bitrate and constant RF are the same (only a computer could tell the two apart). The difference is, you cannot predict file size when using CRF, but you cannot predict quality when using 2-pass ABR. So that brings up a point I'm not clear on with Average ...

Re: RF and File Size

I can't see where to edit the posts here. Wanted to add that I'd like to be able to find the resulting file size of a video without having to actually encode it. Thought maybe there might be a tool to do that or something. So I guess I'm stuck with encoding a movie at various RF values to see how th...

Re: RF and File Size

Thanks, I understand that, but file size varies with RF and I'd like to select an RF that arrives at a file size within some range.

RF and File Size

Hello, first post here. Been using Handbrake a while (great software BTW) and I'm having a bit of an issue with something. What I'd like to do it target a file size using Constant Quality. Right now the only way I can see to do that is with trial and error. I don't want to use Average Bitrate becaus...
