The Kindle Video preset outputs H.264 video at 480p with 96 kbps AAC audio in an MP4 container, tailored for Amazon's Kindle Fire tablet line. Kindle Fire devices run Fire OS (a fork of Android) and use relatively modest processors, making the conservative encoding settings of this preset ideal for smooth, stutter-free playback. The low-resolution nature of 3GPP files makes them a natural match for the Kindle's compact screen.

Kindle Fire tablets cannot play 3GPP files natively through their built-in media player. Converting to the Kindle Video preset produces an MP4 that Fire OS recognizes and plays through hardware-accelerated H.264 decoding. The 480p resolution and 96 kbps audio keep file sizes small — important for Kindle models with limited storage (often 16-32 GB).

If you use a Kindle Fire as a portable video player for travel, commutes, or offline entertainment, converting your 3GPP phone recordings to this preset ensures reliable, battery-efficient playback.

FFmpeg re-encodes the 3GPP source to H.264 Baseline Profile at 480p (or source resolution if lower) with AAC LC at 96 kbps. Baseline Profile ensures compatibility with all Kindle Fire hardware, including budget models with less capable processors. The MP4 container includes faststart metadata for quick loading.

All Kindle Fire tablets from the original 2011 model onward support H.264 Baseline in MP4. This includes Fire 7, Fire HD 8, Fire HD 10, and all Kids editions.

USB cable to the 'Videos' directory, Amazon's Send to Kindle service, or via cloud storage apps installed on the Kindle.

For speech from AMR sources, 96 kbps AAC is more than sufficient. For music content, you might prefer 128 kbps, but the 3GPP source quality is the real limiter.

Yes. The Kindle preset uses standard H.264+AAC+MP4, which plays on any Android phone or tablet.

Budget Kindle Fire models have modest processors. Baseline Profile requires the least processing power and ensures smooth playback on all Kindle hardware.
