# Sora Video Upscaler

> Upload the Sora clip to an AI video upscaler and choose a bigger size. Sora 2 only made 720 × 1280 or 1280 × 720 video (Sora 2 Pro went up to 1080p), and OpenAI shut the Sora API down on 24 September 2026, so upscaling the file you saved is the only way to sharpen it. Kenerate's AI Video Upscaler takes clips up to 5 minutes and 100 MB and outputs 1080p, 2K or 4K for 9–24 credits per second.

## Key facts
- Sora 2 output: 720 × 1280 or 1280 × 720
- Sora 2 Pro max: 1080 × 1920 / 1920 × 1080
- Upscale to: 720p · 1080p · 2K · 4K
- Credits per second: 6 · 9 · 15 · 24
- Clip limit: 5 min · 100 MB
- Sora status: Shut down 24 Sep 2026
- 720p · 6 credits/s (AI Video Upscaler): Sora clip up to 5 min / 100 MB → Same size as Sora 2, cleaner. Compression clean-up only.
- 1080p · 9 credits/s (AI Video Upscaler): Sora clip up to 5 min / 100 MB → ≈ 1080 × 1920 for 9:16. TikTok, Reels, Shorts and YouTube.
- 2K · 15 credits/s (AI Video Upscaler): Sora clip up to 5 min / 100 MB → ≈ 1440 × 2560 for 9:16. Edits and QHD screens.
- 4K · 24 credits/s (AI Video Upscaler): Sora clip up to 5 min / 100 MB → ≈ 2160 × 3840 for 9:16. 4K TVs, 4K timelines, Sora 2 Pro 1080p sources.

## Steps
1. Find your saved Sora clip — Use the original MP4 you downloaded from Sora, not a re-download from TikTok or Instagram — those are compressed again.
2. Upload it to the Video Upscaler — MP4, MOV or WebM up to 5 minutes and 100 MB. The length is read from the file and the price shows before you start.
3. Choose 1080p, 2K or 4K — Sizes are a pixel budget: a 9:16 Sora clip at 1080p comes out about 1080 × 1920, at 4K about 2160 × 3840.
4. Compare and download — Check the before/after viewer, then download the MP4. Kenerate adds no watermark of its own.

## In depth

### Why Sora 2 clips look soft
Standard Sora 2 rendered only 720 × 1280 or 1280 × 720; the 1080p sizes were Sora 2 Pro only [1]. On a phone that looks fine, but a 1080p feed, a 4K timeline or a TV stretches it, and social apps compress it again on upload.

### Why you can't fix it in Sora
OpenAI says the Sora 2 models and Videos API were shut down on 24 September 2026, with no one-to-one replacement [1][2]. A saved Sora file can't be regenerated larger — upscaling is what's left.

### What an AI upscaler adds
Resizing in an editor interpolates new pixels from old ones, so the picture gets bigger but stays soft. Video super-resolution uses neighbouring frames to rebuild plausible detail [3], and Kenerate's engine also removes compression blocking.

## FAQ
Q: How do I enhance Sora AI video quality?
A: Upscale the clip you saved. Upload the original Sora MP4 to Kenerate's AI Video Upscaler, choose 1080p, 2K or 4K and download the result. The AI rebuilds detail across frames instead of stretching pixels, and keeps the clip's length, frame rate and shape. You can't re-render the clip at a higher resolution in Sora any more, because OpenAI shut it down.

Q: What resolution were Sora 2 videos?
A: According to OpenAI's model page, Sora 2 made 720 × 1280 (vertical) or 1280 × 720 (widescreen) video. Sora 2 Pro also offered 1024 × 1792, 1792 × 1024, and 1080 × 1920 / 1920 × 1080. Most Sora clips people saved are therefore 720p, which is why they look soft on big screens.

Q: Can I still use Sora 2 to make a higher-resolution version?
A: No. OpenAI closed the Sora apps on 26 April 2026 and says the Sora 2 models and Videos API were shut down on 24 September 2026. Existing files can only be improved by upscaling them. For new clips, see Kenerate's Sora 2 alternatives page, which compares Veo 3.1, Kling 3.0, Seedance 2.5 and Wan 3.

Q: Is there a free Sora video enhancer?
A: Kenerate runs in the browser with nothing to install, and new accounts get starter credits to try the upscaler on their own clip. After that it is paid per second with credits — 6 per second at 720p, 9 at 1080p, 15 at 2K and 24 at 4K — with no subscription required and no watermark added.

Q: How much does it cost to upscale a Sora clip?
A: It depends on length and size, billed per whole second. A 10-second Sora clip costs 60 credits at 720p, 90 at 1080p, 150 at 2K and 240 at 4K. The exact price shows in the tool after the length is read from your file, before you start.

Q: Does upscaling remove the Sora watermark?
A: No, and Kenerate doesn't offer watermark removal. The upscaler only adds resolution and repairs compression, so anything in the picture — including Sora's moving watermark — stays and gets sharper along with the rest of the frame.

Q: Should I upscale a Sora clip to 1080p or 4K?
A: For TikTok, Reels, Shorts and most YouTube uploads, 1080p is enough and costs 9 credits per second. 4K (24 per second) makes sense for 4K edits and TVs, or for Sora 2 Pro clips that were already 1080p. From a 720p source, 4K is a 3× jump in each direction, so fine texture is partly reconstructed.

Q: Will a vertical Sora video stay vertical?
A: Yes. Each size is a pixel budget, not a fixed frame, so a 720 × 1280 Sora clip at 1080p comes out at about 1080 × 1920 and at 4K at about 2160 × 3840 — no black bars and no cropping.

Q: How long does a Sora upscale take?
A: A few minutes for a short clip at 720p or 1080p. 2K and 4K take much longer because the AI rebuilds many more pixels in every frame; in Kenerate's own test, 4 seconds at 4K took about 4.7 minutes. Trim the clip first to save time and credits.
