What changes when you convert FLV to WEBM
- Both formats are lossy. Re-encoding adds a second generation of loss, so keep quality high (80+) unless size matters more than fidelity.
- WEBM video supports transparency, but the source has none to keep — nothing is invented.
- Both formats support animation; animated input stays animated where the target truly supports it.
- WEBM video encoding exposes a quality control; around 80 is the usual sweet spot.
