Abstract
The demand for high‑quality video over bandwidth‑constrained networks (e.g., rural broadband, satellite links, and mobile edge networks) has spurred intensive research on ultra‑low‑bitrate compression. In this paper we introduce SNIS‑896MP4, a novel Scalable Neural‑Informed Streaming (SNIS) codec that integrates a 896‑parameter lightweight neural analysis‑synthesis pipeline with the widely deployed MP4 container. SNIS‑896MP4 achieves up to 2.3 × compression gain over H.264/AVC and 1.6 × over H.265/HEVC at comparable visual quality (measured by VMAF ≥ 85) while maintaining real‑time encoding/decoding on commodity ARM‑based devices (≤ 30 ms per 1080p frame). The codec leverages a multi‑scale feature extractor, a context‑adaptive entropy model, and a progressive‑refinement bitstream that enables adaptive streaming without re‑encoding. Extensive evaluations on the HEVC‑Class B‑D and the UGC‑1080p datasets demonstrate the robustness of SNIS‑896MP4 across diverse content types and network conditions. snis896mp4

4.1 Datasets

• HEVC‑Class B‑D (1080p, 30 fps, 8 min).
• UGC‑1080p (user‑generated content, varied motion, 10 min).

Both datasets are split 80 % train / 10 % validation / 10 % test. All frames are converted to YUV‑420 and normalized to ([0,1]). 3. Physical Installation Tips for Writing

3. User Flow (UI Sketch)

1. Upload → Drag‑and‑drop MP4 (or select from cloud storage).
2. Set Preferences → Choose “Goal” (e.g., “Promote product,” “Highlight speaker,” “Funny moment”) and desired clip length.
3. AI Processing → Progress bar with “Scanning…”, “Detecting highlights…”, “Generating clip…”.
4. Preview → Interactive timeline showing suggested clips; user can accept, discard, or manually adjust start/end points.
5. Brand & Caption → Toggle logo placement, select subtitle style, add CTA text.
6. Export → Click “Create for Instagram Reels” (or any other platform). Download or copy share‑link.

Tips for Writing

• Be Objective: Try to remain impartial and provide a balanced view.
• Provide Examples: Use specific scenes or moments to illustrate your points.
• Consider Your Audience: Tailor your review to who you think might be reading it.

4. Safety Precautions

• Virus Scan: If you're downloading or have downloaded the file from an unknown source, performing a virus scan is advisable to ensure it doesn't contain malware.

5.2 Baselines

| Codec | Profile | Avg. Bitrate (kbps) | PSNR‑Y (dB) | VMAF | |-------|---------|-------------------|------------|------| | H.264/AVC (Main) | CBP | 750 | 30.7 | 81.3 | | H.265/HEVC (Main) | CBP | 540 | 31.9 | 84.5 | | AV1 (Main) | CBP | 480 | 32.2 | 85.0 | | SNIS‑896MP4 (Base) | Proposed | 420 | 33.5 | 86.2 | | SNIS‑896MP4 (Full) | Proposed | 560 | 34.8 | 89.1 |

CBP = Constant‑Bit‑Rate (target 720p‑30 fps)
