 Re: How to watch older YouTube videos in Higher Quality on YouTube (YouTube HQ hack)
If you add " &fmt=22", some YouTube videos are now available at an even higher quality, which makes the full screen view a very useful option. Compare:
Code:
http://www.youtube.com/watch?v=l5DNZHR0oI8 (320x180 mono)
http://www.youtube.com/watch?v=l5DNZHR0oI8&fmt=18 (480x270 stereo)
http://www.youtube.com/watch?v=l5DNZHR0oI8&fmt=22 (1280x720 stereo)
All fmt options for YouTube I know: - Standard: MP3, ~64 kbps, 22.05 KHz, mono (1 channel)
- fmt=5: MP3, ~64 kbps, 22.05 KHz, mono (1 channel) (little difference in video bitrate)
- fmt=6: MP3, ~66 kbps, 44.1 KHz, mono (1 channel)
- fmt=18: AAC, ~126 kbps, 44.1 KHz, stereo (2 channels)
- fmt=22: AAC, ~248 kbps, 44.1 KHz, stereo (2 channels) (it's rare, only if uploaded video have 1280x720)
- fmt=34: AAC, ~68 kbps, 22.05 KHz, stereo (2 channels)
- fmt=35: AAC, ~112 kbps, 44.1 KHz, stereo (2 channels) (it's rare)
- fmt=13 and fmt=17 > only on mobile devices (3GP with AMR or AAC audio)
