I found quite a few posts in this thread talking about what RF setting to use to get a high quality encoding. For example a few people stated that RF=16 gives a high quality result but going down to RF = 15 for 14 may be slightly better. The problem I have is many such posts never state if they are talking about compressing DVD or Blu-rays. The "best" settings can be different for compressing 1080p Blu-rays vs. DVDs and we need to know the context for any suggested settings for Handbrake.

I have encoded 3 and 4 hour 1080p recordings of meetings and can cut them down to 1 gig with an RF setting of 10. Doesn't look too bad either, since the camera stays still on a tripod.

Since Avatar was such a huge visual spectacle, I wanted to do better than 16. I wanted to get as close to lossless as I can. Know of any way to do that? I suppose I can just play the rip. <img alt="" class="inlineimg" src="http://www.avsforum.com/avs-vb/images/smilies/redface.gif" style="border:0px solid;" title="embarrassment"></div>

The best quality you can get is watch the original rip, <b>ANY re-encoding will reduce quality</b> (other than RF: 0 - 100% which will be the same quality as the original rip, but the file will be much larger, so it's a pointless setting).<br><br>
The whole point of using handbrake is reducing the file size, if you don't care about file size then don't transcode at all, just keep the original.<br><br>
If you want a smaller file and 16 is not good enough quality, then try 15 or 14.
That will not work because my original is MKV and I need m4v for iTune use.

You don't need m4v for iTunes. mp4 is just fine. Changing the extension to m4v usually just makes it look like its associated with a d/l with some protections on it. For a personal encode, mp4 with h264 should work just fine and also work in iTunes if you use it to catalog your stuff. If on a Mac get Subler and use it to set your mp4s to TV Show, Movie etc.. and add artwork and content ratings if desired. Easier than in iTunes.

That still does not help if you have an MKV file.

mp4 and m4v both work on iTunes yes and they both of compression. MKV has the best image as far as I can see but iTunes does not work with MKV. You can do a Blu-ray to mp4 pass thru but all I get is audio sync problems when I try that.

Just trying to see how to maintain the highest video/audio quality on an iTunes playable file.

Try something simple like ffmpeg.

Code:
ffmpeg -i input.mkv output.mp4
There are a host of options that can be used. To keep it simple hopefully you won't need to use them. If you are using Ubuntu you use avconv instead.

Code:
avcon -i input.mkv -codec copy output.m4v

MKV is a Wrapper for a variety of formats. The mkv in some cases IS just plain old H264. Subler is a Mac program that can strip the mkv wrapper away without re-encoding. It just doesn't handle some surround formats as well as one could hope. It also will help modify subtitles if desired. But the point is the way everyone talks about mkv's as a Format is not correct, it's a wrapper, a container, one that can hold many formats within it. With the correct software that will strip the wrapper off a H264 MKV without doing any transcoding there should be no sync issues or anything else as nothing has really been modified. Now if the MKV is a shell for a AVC Codec hiding something other than MPEG4 then that will change the way you deal with it to be iTunes compatible. Transcoding rears it's ugly head.

I'm a Mac user and have to get the MKV out of the equation if I want to use the latest OS, find software that will deal with it on the fly because Perian doesn't work with QuickTime anymore, or pass it off to a external device (WDTV in my case) that will play it on a HDTV. I've been dealing with the odd MKV headache here and there for years.

That's why my ffmpeg/avconv suggestions are so simple, nothing to transcode. Just copy the original audio & video codecs over to the new format.
