Limelight
Lossless Video Recording
Lossless recording captures video using compression that preserves every pixel of the original source without quality loss.
Lossless recording refers to capturing video with a codec that compresses data without discarding any of it, so the decoded output is mathematically identical to the source. This contrasts with lossy codecs like H.264, which achieve small files by permanently removing detail the eye is less likely to notice. Truly lossless capture guarantees pixel-perfect frames, which matters for archival masters and repeated re-editing.
The tradeoff is size and performance: genuinely lossless video produces very large files and demands high disk throughput, so most creators instead target visually lossless capture with high bitrates. The goal is footage clean enough that text stays sharp and gradients stay smooth through editing and re-export, avoiding the generational quality loss that comes from re-encoding lossy files repeatedly.
For screen recording, sharp, artifact-free capture is essential because on-screen text and UI edges reveal compression flaws instantly. Limelight records locally at high quality on your Mac and edits before a single final encode, minimizing generational loss so exported demos stay crisp.
Why Limelight
- ▸Compression that discards no original data, yielding pixel-perfect frames.
- ▸Ideal for archival masters and footage that will be re-edited repeatedly.
- ▸Produces very large files and requires high disk throughput.
- ▸Limelight records locally at high quality to keep text and UI edges sharp.

FAQ
- Is lossless the same as high quality?
- Not exactly. Lossless means zero data is discarded, while high quality can still be lossy. Many workflows target visually lossless capture as a practical middle ground.
- Why are lossless files so large?
- Because no perceptual data is thrown away, lossless compression can only shrink files modestly, so recordings consume far more storage and disk bandwidth.
- Does Limelight record locally?
- Yes. Limelight records entirely on your Mac at high quality and uploads nothing, keeping capture fast, private, and clean before the final export.
