I should evaluate the file size. 720p Web-DL for a 90-minute movie might be around 1-1.5 GB. The codec efficiency of .mkv with H.264 is standard. Picture quality – maybe there's some loss compared to a 4K theater version, but for a downloaded file, it's decent. Audio quality in Hindi might be good, but it depends on the source. If it's ripped from a streaming service, the audio might be lossy.

The Substance , directed by Coralie Fargeat, is a 2024 body-horror film that critiques themes of identity, vanity, and ageism through its surreal, high-stakes narrative. The story centers on a disgraced CEO who becomes entangled with a black-market drug, leading to a visceral exploration of self and societal pressures. With Demi Moore's standout performance and Fargeat's signature use of vibrant visuals, the film is a bold, thought-provoking addition to the genre that lingers long after its credits roll.

The file described in the query appears to be a WEB-DL (Web Distribution Digital) source, meaning it was likely ripped from a streaming platform. The 720P resolution offers a decent balance between file size and quality, making it suitable for viewing on most HD screens, though it falls short of the 4K theatrical experience. The Hindi audio-HQ suggests the track is of high fidelity, potentially with lossless or near-lossless compression, which is a plus for non-English speakers or fans of the language. The .mkv container ensures stable playback and likely supports multiple audio/subtitle tracks, enhancing accessibility.
