It's the player that deinterlaces. The MPEG stream contains flags that tells about interlacing. A proper decoder/player must handle those flags. But what is "proper" for a player may be inadequate for an editor/compositor. Naive deinterlacing is OK for normal speed playback without scaling, warping, cross-fading or sharpening, which is what players do. Cinelerra would need something much more clever, and the required changes would be deep. -- Herman Robak _______________________________________________ Cinelerra mailing list [email protected] https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
