[HOWTO] Converting films for the Galaxy Tab
Ok, I present to you what I believe to be the best trade off between file-size and quality, given when I'm likely to watch a film on this thing. Feel free to disagree, everyone has their own preferences.
Why have I chosen these settings?
Well, given that I normally watch films on a television, watching them on the Tab is only gonna happen when I'm on the move. So a >1GB video seems pointless, as on a screen that size you'll barely notice the difference in quality. So I aimed to get a film in to ~500MB and to a quality that is still watchable. I went for 500MB as a target because a film that's ~700MB on a 15.6" laptop screen is perfectly watchable. On the Tab the screen is smaller, and the pixel density higher, so we can afford a smaller file size for a video of the same dimensions. I chose to upscale during the encode instead of during playback because the Tab does a really bad job of upscaling (horribly pixilated, especially in high contrast). I think that you could get a film to 400MB, but that's too far for my taste.
To reiterate, I use these settings to keep file size to a minimum while maintaining a watchable quality. I do not need a 2GB HD film when I can fit 4-5 films in that space. If I want to watch a film at a high quality I use my 42" TV, not a 7" tablet.
What you need:
How do I do it then?
- A film to convert for use on your tablet
- Load up handbrake, and select your source and destination files.
- Ensure the preset is set to "Normal"
- On the "Picture" tab make sure "Anamorphic" is set to "None"
- Ensure "Keep aspect ratio" is ticked
- Set the height of the output to the max it'll allow (assuming you're using an SD film. If not, set the width to 1024)
- Switch to the "Video" tab
- Ensure "Constant Quality" is used, and set the RF value to ~27. Larger numbers mean lower quality, and it's a logarithmic scale.
- Switch to the "Audio" tab
- Change the mixdown to stereo and the sampling rate to 48
- Hit "Start"
After a number of hours (at least the length of the film you're converting) you'll have a ~500MB video file (depends on the length of the film, and genre) ready for playback on your tab. When you hit play tap the screen, then tap the zoom setting button (top right) once. This will correct the aspect ratio.
For higher quality (and larger file sizes) make the RF lower
Feedback is welcomed, I want to know how you guys do it.
