What is AVI?

AVI (Audio Video Interleave) is a legacy multimedia container format introduced by Microsoft in 1992.

What is FLC?

FLC Animation is Autodesk Animator Pro's enhanced animation format, the successor to FLI with higher color depth and resolution.

When Should You Use AVI vs FLC?

Use AVI When...

Reach for AVI when your priority is legacy video, windows applications — its efficient compression makes sharing fast and storage minimal.

Use FLC When...

Reach for FLC when your priority is retro game cutscenes, legacy 2d animation — its uncompromising quality ensures every detail is preserved.

AVI vs FLC: Key Differences

  • •The core technical difference: AVI relies on lossy compression whereas FLC uses lossless compression.
  • •Converting from AVI to FLC changes compression type: lossless source becomes larger but with full quality preservation.
  • •How transparency is handled: FLC supports transparency, so alpha information is preserved during conversion.
  • •Storage footprint: Very large for uncompressed video for AVI vs Moderate for 256-color animations for FLC.
  • •Primary audience: AVI is built for legacy video, windows applications scenarios, while FLC focuses on retro game cutscenes, legacy 2d animation — pick the format that matches your output requirement.

Advantages of AVI

  • ✓AVI applies lossy compression specifically calibrated for Legacy video, Windows applications.
  • ✓AVI enjoys broad native support across operating systems, browsers, and creative tools alike.
  • ✓AVI delivers impressive compression ratios, shrinking files dramatically while keeping visual quality high.
  • ✓You will find AVI support built into virtually every tool that handles Legacy video, Windows applications — no plugins or converters needed.

Advantages of FLC

  • ✓FLC applies lossless compression specifically calibrated for Retro game cutscenes, legacy 2D animation.
  • ✓FLC enjoys broad native support across operating systems, browsers, and creative tools alike.
  • ✓FLC guarantees every bit of the original data survives — no approximations, no shortcuts.
  • ✓You will find FLC support built into virtually every tool that handles Retro game cutscenes, legacy 2D animation — no plugins or converters needed.

Best Practices for AVI to FLC Conversion

  • →For AVI to FLC: encode at the target platform's native resolution — upscaling or downscaling adds unnecessary artifacts
  • →Test a short clip before converting the entire AVI file — this confirms FLC settings produce acceptable quality
  • →FLC is widely supported but choose bitrate carefully to balance quality and file size
  • →Use constant bitrate (CBR) for streaming delivery and variable bitrate (VBR) for archival storage
  • →Keep the original file in case you need to re-encode with different settings
  • →Check audio sync after conversion — container changes can sometimes cause drift

Troubleshooting AVI to FLC Conversion

  • !FLC won't play on target device → check codec compatibility (H.264 has broadest support)
  • !Audio out of sync after AVI to FLC conversion → try re-muxing with a different container format
  • !FLC quality is too low → increase the bitrate; for 1080p video, 8-15 Mbps is recommended
  • !File size increased converting AVI to FLC → lossless or higher-bitrate outputs naturally produce larger files

FAQs

Is converting AVI to FLC free?

Yes, GoConvertFile offers free conversion of AVI to FLC for files up to 100MB. No registration required.

How long does it take to convert AVI to FLC?

Most AVI to FLC conversions complete within seconds for standard-sized files. Larger files may take longer depending on the conversion complexity.

What is FLC best used for?

FLC is ideal for retro game cutscenes, legacy 2d animation. FLC Animation, Autodesk Animator Pro FLIC animation format

Does converting AVI to FLC lose quality?

No, converting AVI to FLC does not cause additional quality loss — FLC uses lossless compression. However, any artifacts already present in the original AVI file will persist in the FLC output.

What file size should I expect after converting AVI to FLC?

FLC files are typically 2-5x larger than equivalent AVI files because FLC preserves all pixel data. This is expected and necessary for lossless quality.
