Technical Details
Video Codec Conversion
Converts FLV’s VP6 or H.264 video streams to H.263 or MPEG-4 Part 2 codecs used in 3GP format. Automatically adjusts bitrates from typical FLV rates (500-2000 kbps) down to mobile-optimized rates (64-384 kbps) while maintaining acceptable quality for small screens.
Audio Processing
Transcodes FLV audio (typically MP3 or AAC) to AMR-NB (Adaptive Multi-Rate Narrowband) at 12.2 kbps, the standard for 3GP mobile audio. Also supports AMR-WB for higher quality when compatible with target device specifications.
Resolution & Bitrate Optimization
Automatically scales common FLV resolutions (720p, 480p, 360p) down to mobile-standard formats like QCIF (176×144), CIF (352×288), or QVGA (320×240). Implements smart bitrate allocation to maintain visual quality within 3GP’s bandwidth constraints.

Frequently Asked Questions
Will my FLV videos lose quality when converted to 3GP?
Some quality reduction is expected since 3GP uses aggressive compression for mobile compatibility. However, Convertify optimizes the conversion to maintain the best possible quality within 3GP’s constraints, and the smaller screen sizes of mobile devices help mask compression artifacts.
Can I convert FLV videos with different codecs to 3GP?
Yes, Convertify handles FLV files encoded with VP6, H.264, or Sorenson Spark codecs and converts them all to 3GP-compatible H.263 or MPEG-4 Part 2 video with AMR audio encoding.
What mobile devices can play the converted 3GP files?
3GP files work on virtually all mobile phones including old Nokia, Samsung, and Motorola feature phones, as well as basic Android devices and older smartphones. It’s one of the most universally supported mobile video formats.
How much smaller will my FLV file become as 3GP?
Typically 70-90% smaller depending on the original FLV quality. A 50MB FLV video often becomes 5-15MB as 3GP due to lower resolution, reduced bitrate, and efficient AMR audio compression.
Can I batch convert multiple FLV files to 3GP at once?
Yes, with Convertify’s batch processing feature (available in paid tiers), you can convert hundreds or thousands of FLV files to 3GP simultaneously, saving hours of manual conversion work.
Do converted 3GP files work for MMS messaging?
Yes, 3GP files are specifically designed for mobile messaging systems. The small file sizes and mobile-optimized encoding make them perfect for MMS sharing, though you should check your carrier’s specific size limits.
Will audio quality be preserved in the FLV to 3GP conversion?
Audio is converted to AMR format optimized for speech and mobile playback. While music quality may be reduced, voice content often sounds very good, and the format is specifically designed for mobile audio transmission.
Can I convert FLV files with subtitles or multiple audio tracks?
3GP format has limited support for advanced features like subtitles or multiple audio tracks. Convertify will convert the primary video and audio streams, but additional tracks may need to be handled separately or embedded differently.
