Install and use the latest FFmpeg and x264

1. Install guide for Ubuntu

2. x264 ffmpeg mapping and options guide

3. Basic ffmpeg usage

4. x264 settings

5. FFmpeg A/V manipulation guide at http://howto-pages.org/ffmpeg/

6. Correcting A/V sync with http://www.kkoncepts.net/node/69

UPDATE June 2013: This guide for Ubuntu 13.04 Raring Ringtail and Linux Mint 15 Olivia will provide a local install of the latest FFmpeg tools and libraries including several external encoding and decoding libraries (codecs). This will not provide a system installation and therefore will not interfere with anything such as repository packages.

Cirque du Soleil - Beatles LOVE for iPad and iPhone

Problem: Sample videos had poor image quality and were extremely blocky.

Fix: Designed custom settings for all web browsers and mobile devices to display high quality playback.


Unicorn Media - Correcting MPEG4 A/V Sync

Problem: Audio and video out of sync, due to corrupted QuickTime timescale in MPEG-4 source.

Fix: Gave new Final Cut Pro and Compressor settings for correcting the problem.


Grab Networks - Improving quality across platforms

Problem: Video encoding was not playing back on all mobile devices.

Fix: Designed custom settings to make video look good on all platforms.


Lullabot - Video stuttering with dropped frames

Problem: Source file was 15 frames-per-second and Lullabot was seeing stuttering on output, where a frame of video would hang every couple minutes.

Fix: Changed output framerate from 29.97 to 30 frames-per-second to make playback smoother and remove the misbehaving drop frame.
