Concat Video Chunks
Concatenate two decoded video chunks. Optionally trim B's first N frames to remove the duplicate reference frame. Simplest join method — no blending needed when using rolling reference (chunk B's first frame already matches A's last).

| Name | Type | Default | Description |

| trim_b_start | INT | 10–100 | Number of frames to trim from the START of chunk_b before concatenating. Default 1 = drop B's first frame (which duplicates A's last frame in rolling-reference workflows). |
