What is FLC?

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

What is H265?

Raw H.265/HEVC stream, high-efficiency video coding — stored as video/h265 — uses lossy encoding to handle ultra hd video encoding, 4k/8k content. Typical file sizes: varies by content.

When Should You Use FLC vs H265?

Use FLC When...

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

Use H265 When...

Reach for H265 when your priority is ultra hd video encoding, 4k/8k content — its efficient compression makes sharing fast and storage minimal.

FLC vs H265: Key Differences

  • •The core technical difference: FLC relies on lossless compression whereas H265 uses lossy compression.
  • •Moving from FLC (lossy) to H265 (lossy) means the output file will be significantly smaller — but at the cost of some visual fidelity.
  • •How transparency is handled: H265 does not support alpha channels — transparent areas in the source will become opaque.
  • •File sizes: FLC files typically range Moderate for 256-color animations and H265 files N/A.
  • •Use case fit: FLC targets retro game cutscenes, legacy 2d animation and H265 targets ultra hd video encoding, 4k/8k content — your choice depends on which workflow stage you are serving.

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.

Advantages of H265

  • ✓The lossy nature of H265 means file sizes stay reasonable while handling Ultra HD video encoding, 4K/8K content efficiently.
  • ✓From mobile devices to enterprise servers, H265 is recognized and supported everywhere.
  • ✓Storage and bandwidth costs drop significantly when using H265 thanks to its efficient compression.
  • ✓H265 is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Troubleshooting FLC to H265 Conversion

  • !H265 won't play on target device → check codec compatibility (H.264 has broadest support)
  • !Audio out of sync after FLC to H265 conversion → try re-muxing with a different container format
  • !H265 quality is too low → increase the bitrate; for 1080p video, 8-15 Mbps is recommended
  • !File size increased converting FLC to H265 → lossless or higher-bitrate outputs naturally produce larger files
