Frequently Asked Questions
Will converting AVI to FLV reduce video quality?
The quality depends on the original AVI codec and target bitrate settings. Converting from uncompressed AVI may show minimal quality loss, while converting already compressed AVI files involves recompression. FLV’s efficient H.264 encoding often provides better quality-to-size ratios than older AVI codecs.
Can I convert AVI files with different codecs to FLV?
Yes, Convertify handles AVI files encoded with various codecs including DivX, Xvid, H.264, MJPEG, and uncompressed formats. All are converted to FLV using standardized H.264 or VP6 video compression for consistent compatibility.
How much smaller will my AVI files become as FLV?
File size reduction varies by source codec. Uncompressed AVI files typically reduce by 70-90%, while already compressed AVI files may reduce by 20-50%. The exact reduction depends on content complexity, resolution, and chosen quality settings.
Do FLV files work in modern web browsers?
Modern browsers have deprecated Flash Player support, making FLV primarily useful for legacy applications, specialized players, or conversion to other formats. For current web use, consider converting to MP4 instead of FLV.
Can I convert multiple AVI files to FLV simultaneously?
Yes, Convertify supports massive batch processing, allowing you to convert thousands of AVI files to FLV format simultaneously without file size limits or conversion quotas.
Will audio quality be preserved when converting AVI to FLV?
Audio is converted to AAC or MP3 format within the FLV container. If your AVI has uncompressed audio, there may be slight quality differences due to compression. Most users won’t notice significant audio quality changes.
Is there a file size limit for AVI to FLV conversion?
No, Convertify has no file size restrictions. You can convert large AVI files that exceed the limits of online converters, all processed locally on your Windows computer.
Can I convert AVI files with multiple audio tracks to FLV?
FLV format typically supports single audio streams. During conversion, the primary or first audio track from your multi-track AVI file will be preserved in the output FLV file.
