Convert videos for your tablet
This tutorial aims to convert our videos to a more mobile format while trying to preserve the quality as much as posible but reducing the video size. HandBrake is an open source multiplatform video transcoder that will let us achiveve this.

As you can see, HandBrake lets us choose from different presets and we can save our presets too, to make bulk conversion easier. For this tutorial, we will start with the Normal profile selected, you just need to change the following things in each tab.
Picture Tab
Change the following, to resize the video to 720p:
- Anamorphic: None
- Modulus: 16
- Check Keep Aspect Ratio
- Change dimensions to 1280x720 (720p)

Video Tab
Change the Rate Factor. Lower Rate Factor equals to better quality but higher file size. A good value is around 20-24 RF in Constant Quality.

Audio Tab
Change the following to adjuts the audio parameters. A bitrate around 128-192 is good enough.
- Mixdown: Stereo
- Bitrate: 128-192

Subtitles Tab
If the video has subtitles, you can embed them by selecting from the dropdown and hitting the 'Add' button. Also Handbrake lets you add an external srt subtitle if you have one and want to embed them in the container.
Advanced Tab
Change the following to achieve a baseline H.264 profile:
- Maximum B-Frames: 0
- Uncheck CABAC Entropy Coding
- Uncheck 8x8 Transform
- Uncheck Weighted P-Frames

Encode the video
Just hit the start button and watch your video encode.
Save your preset
If you're satisfied with the quality of the final encoded video, don't forget to save your preset for future use. This can be done by clicking on Preset > Save preset and giving the preset a name.
Extras for MKV
If you have a video with SSA/ASS (Sub Station Alpha) subtitles and you find they doesn't show well in MP4, reencode the video with the previous settings and change the container to MKV. If you still find the MKV file doesn't play as smooth as it should, get mkvtoolnix and follow these instructions:
- Click on add button to open the mkv file
- Select the first track
- Go to the Extra options tab
- Set Compression to none
- Repeat with the rest of the tracks
- Click on Start muxing
