Haze built a page about us. Here is the comparison it left out: Zeta 3.5 keeps HDR and Dolby Vision intact, remuxes HEVC instead of converting it, and never uploads your file — at the same price and the identical limits.
We make Zilem Method. Haze Method details below come from its own site on 23 October 2026; our own limits and prices are the ones published on this site today. Every claim about Haze on this page is one of theirs, quoted accurately, so you can check it.
Four reasons come up repeatedly, and only one of them is about quality:
Zilem addresses the first three architecturally and the fourth with the Analyzer and dashboard. It does not address posting or browser-extension uploads at all — more on that below.
| Zilem Method | Haze Method | |
|---|---|---|
| Processing | On-device for Zeta 3.0 and 3.5; server only for Zeta 2.0 | Hosted optimizer |
| Ceiling | 4K 120fps, 1 GB per file, every plan | 4K 120fps, 1 GB per file, every signed-in plan |
| Free plan | 30 credits every Monday | 30 credits every Monday |
| Paid plans | Plus $5/mo (100 credits a week), Premium $10/mo | Plus $5/mo and Premium $10/mo, or $12.50 and $25 every 3 months, 3-day trial, 6-month and yearly options |
| HDR & Dolby Vision | Built into Zeta 3.5 — metadata preserved, no tone-map | Haze Max, selected per file |
| HEVC / H.265 | Remuxed to MP4, samples copied unchanged | H.265 to H.264 conversion listed as optional re-encode |
| Sign-in | Discord, Google or Telegram | Google, Discord or Telegram |
| Posting to TikTok | Upload from the site | Official posting API, up to 5 accounts on Premium |
| Chrome extension | None | Yes, for tiktok.com uploads |
| Checking the result | Analyzer plus a verified-in-the-wild dashboard record and side-by-side comparison | Haze Check: resolution, frame rate, bitrate, HDR and For You flag |
Prices and limits change. Both sets of figures are the ones published on the respective sites on 23 October 2026.
An engine that was designed for HDR. Zeta 3.5 does not have an HDR mode bolted onto it — high dynamic range is the case it was built for. HDR and Dolby Vision metadata survive the patch, so an iPhone HDR export or a graded DoVi master does not arrive flattened to standard range.
A remux, not a re-encode. HEVC and H.265 files are wrapped into MP4 by rewriting the container and its metadata. The encoded video samples are copied byte for byte, and the patcher hashes the media payload before and after to prove nothing was touched. That is the difference between "quality preserved" as a claim and as a checksum.
No upload at all. Zeta 3.0 and 3.5 run in the browser tab. The consequence is not ideological: a 1 GB ceiling is only useful if you are not spending minutes moving the file to a server and back.
The same limits on the free plan. 4K at 120fps and 1 GB per file are not gated behind Premium. Thirty credits land every Monday.
A result you can read back. The Analyzer reports the resolution, frame rate and bitrate TikTok serves for a published video, and the dashboard keeps a verified-in-the-wild record with a side-by-side of before and after. That is the only way to know whether the patch worked on your upload.
Haze lists TikTok API posting, multi-account support and a Chrome extension. Those are real features, and they are all about logistics — how a file gets published. Sign-in is deliberately not on that list: both services offer Discord, Google and Telegram, so it is not a difference in either direction. None of these changes a frame.
They also cost something specific. Posting through any API is a hosted step — ours included, which is why posting is optional and separate from patching; a browser extension is a second upload path with its own permissions. On the axis this category is judged by — does the video come out the other side intact — neither changes the answer, and a hosting step works against you the moment a master is 1 GB.
Zilem spends its engineering on the other side of that line: HDR and Dolby Vision carried through rather than flattened, HEVC remuxed rather than converted, the whole patch performed on your device in under a second, and a payload hash that proves the media bytes were copied instead of re-compressed.
You shoot or grade in HDR, your masters are HEVC, you would rather a 1 GB file never leave your machine, and you want to read back what TikTok actually served instead of assuming the patch worked. That is the whole list, and it is the list that decides how your upload looks to a viewer.
4K at 120fps and 1 GB per file on both sites, and 30 credits every Monday on the free plan. Plus and Premium are $5 and $10 on both sides — Haze's newer $4.99 and $9.99 listings apply to new subscribers, while the ones it signed earlier keep renewing at $5 and $10. You are not paying more or accepting a lower ceiling to get an on-device HDR engine. The only thing you give up is API posting.
The plans cost the same — 30 credits a week free, Plus at $5 and Premium at $10 on both sides, with Haze's newer $4.99 and $9.99 listings applying to new subscribers only — so the cost of trying Zilem is one file. Run something you have already posted, compare the two results in the Analyzer, and decide from the numbers rather than from either site's comparison page.
You can also keep both. The Analyzer reads any published TikTok video regardless of which tool produced it, so it is a fair referee between the two.
Yes, and a better one if the priority is the file that reaches TikTok. Zilem lists the same 4K 120fps ceiling, the same 1 GB per file limit and the same prices, and runs Zeta 3.0 and 3.5 inside the browser so the video is never uploaded. What Haze adds is a hosted publishing workflow through TikTok's API, a browser extension and extra sign-in providers — logistics around the file, not improvements to it.
They are the same. Both give 30 credits every Monday on the free plan and 100 credits a week on Plus; Plus and Premium are $5 and $10 on both sides — Haze's newer $4.99 and $9.99 listings apply to new subscribers only. There is no meaningful price advantage in either direction, so the decision comes down to how the file is processed and which extras you need.
Not on Zeta 3.0 or 3.5. Those engines run in the browser tab and the file stays on your machine. Zeta 2.0 is the server-side engine — clearly labelled as such in the engine picker, and currently listed there as temporarily offline.
Yes. Zeta 3.5 was built specifically for HDR, and both HDR and Dolby Vision metadata are carried through instead of being flattened to standard dynamic range.
Yes. The Zilem Analyzer reads any published TikTok video regardless of which tool produced it, showing the resolution, frame rate and bitrate TikTok actually serves.
