If you mean you want the files encoded at a resolution of 1024x600, you can tell handbrake what output resolution you want. You'll get far better results by encoding to the desired resolution, format and bit-rate you want the first time than you will re-encoding a second time.

It just works, most especially if you use one of the presets. I've had only one problem with any of my experiments which was that files encoded using the High profile cause xine to crash with some sort of floating point error. I don't personally care about the high profile so to me it's a non-issue. One thing I haven't been able to figure out so far is where you change the presentation size. I presume that presentation size is the one I want to change to 1024x600 as that's the native resolution of the Kindle. However I discovered where I unlock those setting in Handbrake. Do you know? Anyway, it's a very nice little program for anyone else who's GUI oriented like me. Cheers, Mark

I don't personally care about the high profile so to me it's a non-issue. One thing I haven't been able to figure out so far is where you change the presentation size. I think it's the -w and -l options for width and height, respectively. I only use the CLI version (https://trac.handbrake.fr/wiki/CLIGuide), but I'm sure there's somewhere in the GUI to set all that stuff as well. I think that web page is a bit out of date, so do HandbrakeCLI --help for a current set of options. I presume that presentation size is the one I want to change to 1024x600 as that's the native resolution of the Kindle. However I discovered where I unlock those setting in Handbrake. Do you know? -w and -l set the output file's width/height (in pixels). If your pixels are square, then I think that's all you need. If your pixels aren't square, then I think you need some other options. You can get a list of the exact settings for each of the presets by doing HandBrakeCLI --preset-list. Anyway, it's a very nice little program for anyone else who's GUI oriented like me. I don't have the GUI version installed, so I'm afraid I can't help with that end of it, but IIRC the GUI will let you create your own presets. I don't think the CLI version does custom presets, but it would be easy enough to copy the settings from one of the built-in presets into a file, and edit them until you get a command line that works the way you want. Once you've figured out good settings for your device, submit a patch, and next time maybe HandBrake will already just know what to do. :) -- Grant

Handbrake goes directly from DVD to a reasonably sized (1.3GB) m4v file. That file plays fine in xine and looks very good. Being that the Kindle Fire only has about 6GB available for user content that gives me 4 movies at a time which is fine for me but I suspect I can do better. Smaller will generally mean worse looking and longer encoding time. My issue now (I think) is to learn to use ffmpeg to convert from m4v to mp4. You don't need ffmpeg. You just need mv: mv foo.m4v foo.mp4 I'd like to see about reducing the file size a bit if possible.

A program called handbrake was showing up in a lot of links, but it requires an overlay. I've been using handbrake for about a year, and it's _very_ convenient. It has presets for many popular devices. If it knows about your device, it's going to be hard to beat handbrake. [Best of all, you don't have to put up with some horrible GUI to use it.] I have a 4th gen iPod touch, and handbrake knows the right settings to use for that device, so it's a toddle to use. While I have no problem adding yet another overlay (which on is best?) I just stuck the ebuild into /usr/local/portage/media-video and used it from there. I wondered what might be in the normal portage database that others here use for this purpose? You could just use mencoder or transcode, but figuring out all the right options to get the best results for a given device is a non-trivial excercise. In the past, I've used both mencoder and transcode to do stuff like this, but it took several evenings of hacking together shell-scripts to drive them. -- Grant Edwards grant.b.edwardsYow!
