Tips & Best Practices

Ensure input FLV files use codecs supported for conversion to 3GP to avoid processing errors
Expect some quality reduction due to 3GP’s low-bitrate and resolution limitations
Use this conversion mainly for legacy device compatibility rather than high-quality playback
Test converted 3GP files on target devices to confirm playback support
Be aware that some FLV metadata and advanced features may be lost in conversion

Limitations

Conversion requires re-encoding from FLV’s Sorenson Spark or VP6 video codecs to 3GP-compatible codecs, which can increase processing time
Resulting 3GP videos may lose visual and audio quality compared to original FLV sources
3GP format supports fewer metadata and advanced features compared to modern containers like MP4
Both FLV and 3GP are legacy formats with limited compatibility on modern platforms favoring MP4 or WebM
Some codec and profile combinations may not be supported by contemporary players or hardware
