Image To Video Extension And Continuation

via “video extension with bidirectional temporal generation”

Official repository for LTX-Video

Unique: Leverages causal video autoencoder's temporal structure to support both forward and backward video extension from arbitrary frame positions, with explicit handling of temporal causality constraints during backward generation to prevent information leakage

vs others: Supports bidirectional extension from any frame position, whereas most video extension tools only extend forward from the last frame, enabling more flexible video editing workflows
