Recommended settings
The quality preset uses a conservative encode that preserves detail.
Expect smaller savings than aggressive modes — that is the trade-off.
Source files with high bitrates (phone 4K, screen recorders) shrink the most.
Questions
Is this truly lossless?
No re-encode is mathematically lossless, but the quality preset targets a level where differences are hard to see at normal viewing.
How much smaller will my file get?
It depends on the source. Phone recordings and screen captures often shrink 40 to 70% with no visible change.
