StreamFab supports 4K video recording from a range of major streaming platforms, but not every service delivers 4K through the tool — Netflix and Amazon Prime Video are capped at 1080p, while Disney+, Max, Hulu, Apple TV+, and Paramount+ can be downloaded at full 4K resolution — including Dolby Atmos on 4K titles from compatible services. Knowing which services support 4K, and how to configure StreamFab to capture it, is what this guide covers.
4K files are large (typically 8–18 GB per movie) and require adequate storage, a capable playback device, and the right encoder settings to keep quality high without excessive file size. This guide walks through all of it — which services work, what hardware you need, how to configure the settings, and how to troubleshoot when 4K falls back to 1080p.
- In short: StreamFab can download videos in 4K from Disney+, Max, Hulu, Apple TV+, and Paramount+. Netflix and Amazon record at 1080p maximum. This guide covers setup, configuration, and troubleshooting for 4K downloads on all supported platforms.
Can StreamFab Actually Download 4K? Quick Answer
Yes — but with important platform-specific limits.
- 🟢 4K supported (up to 2160p): Disney+, Max (HBO Max), Hulu, Apple TV+, Paramount+ — all can record at 4K on titles and plans that include 4K streaming.
- 🟡 Capped at 1080p: Netflix and Amazon Prime Video record at a maximum of 1080p regardless of your subscription tier or the title's native 4K availability.
- 🟣 Output: MP4 or MKV container, H.264 or H.265 codec; Dolby Atmos audio preserved on supported titles.
The 1080p ceiling on Netflix and Amazon is a platform-level constraint, not a StreamFab limitation. Those services enforce stricter stream protections that prevent 4K capture at the API level. All other major platforms in StreamFab's supported list deliver 4K to the tool's capture layer.

System Requirements for 4K Recording and Storage
4K video is roughly four times the data of 1080p. Recording, processing, and storing it requires more from your hardware than standard HD recording does.

16 GB (for smooth simultaneous playback + recording) |

25 Mbps for 4K streaming |
50 Mbps+ for stable 4K (faster = fewer buffer interruptions during recording) |
|
Storage per 4K movie (~2h, H.265) |
8–12 GB (H.265 at medium bitrate) |
12–18 GB (H.264 at high bitrate for compatibility) |

Dedicated GPU for hardware-accelerated H.265 encoding |
For 4K output, H.265 (HEVC) is recommended: it typically cuts file size by 30–40% compared to H.264 at the same quality level, which matters significantly at 4K (an 18 GB H.264 file becomes roughly 11–12 GB in H.265). The tradeoff is playback compatibility — H.265 requires a hardware decoder on older TVs and devices. If you intend to play on older hardware, use H.264.
Step-by-Step: How to Download 4K Videos with StreamFab
The setup for 4K is identical to standard recording, with one additional step: selecting 4K in the download dialog.
Step 1: Install StreamFab
Download StreamFab from the button above (Windows or Mac). Run the installer — it completes in under two minutes.
Step 2: Open StreamFab Downloader and select your service
Choose the streaming service you want to download from (Disney+, Max, Hulu, Apple TV+, or Paramount+ for 4K). The built-in browser opens and navigates to that service automatically, sign in with your valid account. *Note that a Standard or Basic plan may limit you to 1080p or lower.
Step 3: Navigate to and play your title
Search or browse to the movie or series you want to download. For a movie, click play — StreamFab detects the stream and opens the download dialog. For a series, navigate to the season page and select the episodes you want (or use Select All for an entire season).
Step 4: Select 4K in the download dialog
In the download settings dialog, set Video Quality to 4K (2160p). If 4K does not appear as an option, the title is not available in 4K from your subscription plan or region. Also select your preferred audio track (e.g., English Dolby Atmos) and subtitle language, then click Download Now.
Step 5: Monitor the queue and find your file
The download queue shows progress in real-time. A 4K movie on a 100 Mbps connection typically completes in 15–30 minutes. When done, click the folder icon next to the completed item to open the save location.

4K Quality Settings: Getting the Best Output
The default settings work for most use cases, but adjusting two settings can meaningfully improve either quality or file size at 4K.
- Video codec: H.265 for storage efficiency; H.264 for maximum device compatibility. Change in Settings → Output → Video Codec.
- Container: MKV to preserve Dolby Atmos metadata if your playback setup supports it. MP4 is better for broad device compatibility (smart TVs, mobile devices, etc.).
- Hardware acceleration: Enabled by default (uses GPU encoder). If you get corrupted output files at 4K, disable it in Settings → Advanced → Hardware Acceleration to fall back to CPU encoding.
- Audio: For Atmos titles, select the Dolby Atmos track (labeled "Atmos" or "DD+" in the download dialog) rather than the AAC track to preserve surround audio.
For batch downloads (entire seasons), set the encoder to H.265 before starting the queue. The per-episode file size saving adds up significantly — a 10-episode 4K season in H.264 might occupy 50–60 GB; in H.265 that drops to roughly 30–35 GB at comparable quality.
Why Your Download Is 1080p Instead of 4K
If you selected 4K in the dialog but the output file is 1080p, one of these causes is almost always responsible.
- Your subscription plan doesn't include 4K: Disney+ Standard plan and Max Ad-Lite plan cap streaming at 1080p. Upgrade to the tier that explicitly includes 4K to get the 4K stream.
- The title isn't available in 4K on that service: Not all content is mastered in 4K. The StreamFab dialog only shows resolutions that the title's stream actually offers — if 4K doesn't appear, the content isn't available at 4K on that platform.
- You're accessing from a region without 4K rights: Some titles have 4K available in the US but only 1080p in other regions due to licensing. Using a VPN set to a different region can trigger this.
For more general download failures not specific to 4K, the StreamFab not working troubleshooting guide covers system-level fixes including installation issues and crash recovery.
FAQs
HDR metadata support varies by platform and title. Max (HBO Max) and Paramount+ have confirmed HDR10 and Dolby Vision on supported titles in testing. Disney+ HDR support varies by title. The HDR metadata is preserved when saving to MKV format. To verify HDR in your output file, use MediaInfo (free tool) — look for the HDR Format field in the video track properties.
A typical 2-hour 4K movie saved in H.265 requires approximately 8–12 GB of storage; in H.264 the same film is 14–18 GB. A 45-minute 4K episode is typically 2–5 GB in H.265. For a full 10-episode 4K season in H.265, plan for roughly 25–40 GB. Use H.265 (HEVC) encoding in StreamFab settings to cut storage requirements by 30–40% compared to H.264 at the same quality level.
Yes — as long as your TV or playback setup supports the file format. Options include: connecting a PC or Mac to your TV via HDMI and playing in VLC, using a media server like Plex (runs on a home PC, plays on a Plex-enabled TV or Fire TV Stick), copying files to a USB drive and plugging it into a smart TV's USB port (many 4K TVs play MP4 and MKV natively), or using a media player device like the NVIDIA Shield or Apple TV 4K which support H.265. Save as MP4 for the widest device compatibility; use MKV if you need Dolby Atmos passthrough on an AV receiver.
Conclusion
StreamFab delivers genuine 4K downloads from Disney+, Max, Hulu, Apple TV+, and Paramount+. The recorded files are standard MP4 or MKV — no app required to play them, no subscription needed to access them after recording. Dolby Atmos audio is preserved on titles where the service streams it, and the 4K video quality is visually equivalent to streaming the same title on a 4K display at full quality.
