TempGlitch: Benchmark for Evaluating VLMs on Temporal Glitch Detection in Gameplay Videos

TempGlitch is a new benchmark designed to evaluate vision-language models on temporal glitch detection in gameplay videos, distinguishing temporal anomalies (visible only across ordered frames) from spatial ones (visible in a single frame). The benchmark covers five temporal glitch types with paired glitch-free videos for binary evaluation, and tests 12 proprietary and open-weight VLMs across multiple frame-sampling settings. Results show current VLMs perform near chance on temporal glitches, with neither denser frame sampling nor larger model size reliably improving detection. The work highlights a systematic gap in VLM temporal reasoning capabilities relevant to automated video quality assurance.
