This format is the raw, disc-based version of the episode, typically found in a BDMV folder structure (as opposed to a re-encoded MKV or MP4 file).
Episode Details
Episode Title: Summer Sausage, a Pocket Poncho, and Tony Danza Season: 1 Episode: 21 (Production code: 1YJ721) Original Air Date: May 10, 2018 BDMV Release Context: Usually part of Young Sheldon: The Complete First Season Blu-ray set.
Detailed Feature Breakdown (BDMV Specifics) 1. Video Features young sheldon s01e21 bdmv
Resolution: 1080p (1920x1080) Aspect Ratio: 1.78:1 (16:9) Codec: MPEG-4 AVC (H.264) – High profile, typically @ L4.1 Bitrate: Variable, ~20-35 Mbps (significantly higher than streaming or WEB-DL which are ~4-8 Mbps). This preserves fine detail, grain (if any), and motion clarity. Frame Rate: 23.976 fps (NTSC film standard)
2. Audio Features (Lossless) Unlike streaming, BDMV includes studio-grade audio.
Primary Track: DTS-HD Master Audio 5.1 (24-bit) – Typically around 2.5–4.0 Mbps. This is an exact bit-for-bit copy of the studio master. Secondary/Compatibility: Dolby Digital 5.1 (640 kbps) – For older receivers or downmixing. Dialogue: Centered, crisp, and dynamic range preserved (no heavy compression like broadcast). This format is the raw, disc-based version of
3. Subtitles (PGS Format)
Format: Presentation Graphics Stream (.sup) – Bitmap-based, not text. Languages typically included: English SDH, French, Spanish, occasionally Portuguese. Positioning: Can be repositioned by player; SDH includes sound effects ( [phone chimes] ) and speaker IDs.
4. BD Structure Details (Technical)
Playlist (.mpls file): The episode is not stored as a single file. Video is in STREAM/000XX.m2ts , and the playlist tells the player which .m2ts segments to play in order (including the episode, possible intro, and end credits). Clip Info (.clpi): Contains chapter points, audio/subtitle timings, and seek info. Chapters: Usually 4–7 chapter markers (e.g., "Opening Credits", "Sheldon's plan", "Climax", "End Credits").
5. Episode Synopsis (S01E21) For context, to understand why this episode is notable: Sheldon is invited to speak at a university symposium but struggles with the idea of public speaking. Meanwhile, Mary and George Sr. try to fix up the garage for Georgie to live in, leading to comedic marital tension. The B-plot involves Missy and Meemaw dealing with a garage sale. The title refers to Sheldon's quirky survival prep (summer sausage, poncho) for the big speech, and a Who's the Boss? reference to Tony Danza. 6. Quality Comparison (BDMV vs. WEB-DL/Streaming) | Feature | BDMV (Remux) | WEB-DL (iTunes/Netflix) | |---------------------------|--------------------------|--------------------------| | Video Bitrate | ~30 Mbps | ~6-8 Mbps | | Audio | DTS-HD MA 5.1 (lossless) | Dolby Digital Plus 5.1 | | Compression artifacts | None | Banding/blocking in dark scenes | | Subtitle format | PGS (bitmap) | VTT/TTML (text) | | File size (approx) | ~4-5 GB | ~1 GB | 7.

Detail when you need it. Unlike other mainstream GPU codecs, NotchLC uses variable block size and variable control point bit levels to provide extra detail while allowing greater compression in areas of flatter colours.
NotchLC breaks colour data down into luma and chroma (YUV). 12bits of depth are assigned to luma data, as in many scenarios this is where bit depth is most perceivable. 8bits are assigned to each of the U & V channels.
Rather than specify target bitrates and end up with undetermined quality outcomes, NotchLC takes the reverse approach: during encoding you set a quality level, and the encoder uses the most compression it can while preserving it.
Utilising the modern SSIM measurement method, NotchLC delivers the high-quality results that are needed to be qualified as an intermediary codec. Don’t take our word for it though — read what dandelion + burdock writes in their big, independent 10bit codec test.

Talk to any content creator about codecs and you’ll find encoding times, right at the top of the list of concerns. NotchLC utilises the full power of the GPU to massively accelerate the encoding process.
NotchLC utilises the full power of the GPU to massively accelerate the encoding process. On a consumer PC, encoding can be up to 5.7x faster than realtime at 1080p24. As an example, we encoded the Open Source movie “Big Buck Bunny” (duration 09:57) in just 1 min and 44 secs.
In a CPU codec, the CPU decodes the image and sends the huge raw frames up to the GPU. The secret sauce of a GPU codec is that compressed frames are uploaded and the GPU does the decode. The compressed frames are much smaller in size allowing vastly more video to be passed through the PCI-e bus.
Typically you will see compression ratios of around 5:1 on motion graphics content when compared to raw video. You’ll be able to dial in your final file size by using the encoder’s Quality Level (see the manual).
