The issue provides training logs from Qwen3-VL video SFT but names no source file or test. Start by reproducing the video-loading failure and inspect the video reader path, including the decord EOF fallback and the reported frame-count mismatch. Done means the reported training scenario no longer emits the decoder errors or fails while processing the videos.
