Worked on the ModelTC/LightX2V repository, delivering end-to-end features for advanced audio, image, and video generation. Over seven months, contributed to pose-controlled video, multi-person inference, and user-driven voice cloning by integrating deep learning models and refining backend pipelines. Used Python, PyTorch, and FFmpeg to enhance reliability, support custom output dimensions, and improve audio-video synchronization. Addressed bugs affecting scheduling and animation robustness, while implementing granular user controls such as keyframe-based video editing and hot-swappable adapters. Prioritized maintainability and traceability through clear commit practices, resulting in a stable, flexible media processing platform supporting diverse content creation workflows.

Mar 1, 2026March 2026 (2026-03): ModelTC/LightX2V reliability and scheduling stabilization focused on long-running workers. A targeted bug fix restored the Stage 1 sigma scheduling to its full state at the start of each run to prevent long-lived workers from inheriting a shorter upsampler schedule from prior runs. This maintains the intended Stage 1 behavior (8 steps) after Stage 2 executions, improving predictability and throughput for long-running workloads. The work is captured in commit 38f861ae74bada6ece0541dde951b1e5eb4a90fe with message fix(ltx2): restore Stage 1 sigma schedule at each run start (#963).
