What is FLI?

FLI Animation is Autodesk Animator's animation format, a legacy 2D animated format from the DOS era for game graphics.

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 FLI vs H265?

Use FLI When...

Reach for FLI when your priority is retro game animation, dos animator files — 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.

FLI vs H265: Key Differences

  • •FLI uses lossless compression while H265 uses lossy compression — this is the fundamental technical difference between the two formats.
  • •Converting from FLI to H265 changes compression type: lossy source becomes smaller but with some quality tradeoff.
  • •Transparency: Not supported in H265 — converting from FLI will merge transparency into a solid background
  • •Storage footprint: Small for short animations for FLI vs varies for H265.
  • •Use case fit: FLI targets retro game animation, dos animator files and H265 targets ultra hd video encoding, 4k/8k content — your choice depends on which workflow stage you are serving.

Advantages of FLI

  • ✓FLI compresses data using lossless methods, keeping file sizes manageable for Retro game animation, DOS Animator files.
  • ✓Industry-wide support means FLI files open anywhere — from legacy systems to the latest devices.
  • ✓Lossless quality makes FLI the gold standard for archival and master copies.
  • ✓From professional software to open-source alternatives, FLI works out of the box.

Advantages of H265

  • ✓At its core, H265 relies on lossy encoding — a design choice that makes it perfect for Ultra HD video encoding, 4K/8K content.
  • ✓You won't run into compatibility issues with H265 — it's a universal standard across platforms.
  • ✓File size management with H265: aggressive compression with minimal visible quality loss.
  • ✓Every major application in the Ultra HD video encoding, 4K/8K content space supports H265 natively.
