How Much Is CineX Opus? A One-Time Purchase, and What It Unlocks

CineX Opus is a one-time purchase, not a subscription. It costs US$8.99 in the U.S. App Store and ¥38 in China. The purchase unlocks exactly one practical benefit: unlimited conversions. It does not add a higher-quality mode, a faster mode, or broader format support. Free and paid conversions follow the same rules for the file itself, and the same technical boundaries remain after purchase. In plain terms, you are paying to stop counting successful conversions, not to get a different class of output.

If you only run into an unplayable video once in a while, there is little reason to buy first and test later. The free version includes 5 successful conversions, which gives you room to try the files you actually care about. That matters most when subtitles, HDR, Dolby Vision, or unusual source material are part of your decision.

1. US$8.99 / ¥38 is a one-time purchase

Start with the pricing model: Opus is sold as a one-time purchase. The U.S. price is US$8.99, while the China price is ¥38. Those are regional prices for the same Opus purchase, not two different membership tiers, and there is no monthly or annual plan attached to it.

Once purchased, CineX no longer limits the cumulative number of successful conversions. You still use the same app to convert videos into MP4 files that are better suited to opening directly on iPhone, iPad, and Mac, while playback remains handled by the playback options already available on the device. What changes is how many files you can convert, not what playback capability exists on the device.

Opus costs US$8.99 in the U.S. and ¥38 in China; after the one-time purchase, the conversion count is unlimited.

2. It is not a subscription, and it does not auto-renew

There is no monthly charge and no annual charge. Opus does not renew automatically next month or next year. For someone comparing long-term cost, that is the clearest difference between this model and a recurring plan: the charge happens when you buy Opus rather than repeating on a billing cycle.

It is also important not to stretch “one-time purchase” into promises the product does not make. The defined entitlement here is unlimited conversions. This article is not treating that purchase as a promise that every future feature or every future change will automatically be included.

3. What does Opus unlock? Unlimited conversions, and only that

The free version counts the first 5 successful conversions. Failed conversions, cancellations, and retries do not use the allowance, and deleting a finished output does not give a conversion back. If you want the exact counting rules, see the free-version allowance guide.

From the sixth successful conversion onward, the value of Opus is deliberately simple: you no longer stop because of the cumulative count. There is no second paid perk hidden behind the purchase and no separate “premium conversion” path. For people who regularly clean up videos from different sources, the decision is mostly about frequency: will you keep needing this conversion step often enough that counting each successful file becomes the inconvenience?

The free version and Opus perform the same kind of conversion; Opus removes the cumulative conversion-count limit.

4. Paying does not improve quality or make the same file convert faster

This is the most important expectation to set before paying: the free version and Opus produce files under the same quality rules, and there is no paid speed tier. If a particular file needs a certain kind of processing in the free version, purchasing Opus does not move that same file onto a separate quality or performance track.

When the video is already suitable for the target MP4, CineX may only need to change the container, leaving the picture without recompression. Other files require a full conversion and the picture is processed again. That difference comes from the file itself. It does not come from whether your account is free or paid.

Format support also stays the same. The input formats that have been verified on real devices include MKV, MP4, AVI, and TS. Opus does not turn an unsupported case into a supported one simply because the purchase has been made.

5. What happens when you move to a new iPhone, iPad, or Mac?

The purchase follows your Apple ID. On a new device, you can use App Store purchase restoration to regain access to Opus, so changing to another iPhone, iPad, or Mac does not mean paying for the same purchase again.

That is separate from the free allowance. The free version has its own rules for counting 5 successful conversions; Opus is a purchase state. One answers “how many free successful conversions remain,” while the other answers “has this Apple ID already purchased Opus?” Restoring a purchase should not be read as an extra paid synchronization feature—it simply restores a purchase you already made.

6. Why does the price feel higher than some utility-app price points?

At US$8.99 / ¥38, Opus sits above a common price anchor for comparable utility apps. The case for the price should not be “the paid version must be technically better,” because CineX does not reserve better quality, faster processing, or more formats for Opus. A more useful way to judge the price is to look at three concrete facts: it is a one-time purchase, it removes the conversion-count limit, and the video conversion happens on the device so the video file does not need to be uploaded.

CineX is also not a video player. Its job is to convert a video into MP4 so the resulting file is better suited to the playback methods already available on iPhone, iPad, and Mac. That distinction matters: the reason to pay for Opus is repeated need for the file-conversion step, not access to another playback system.

For a purchase decision, the more reliable approach is to test the files that matter to you before paying. That is especially sensible if your videos depend on subtitles, HDR / Dolby Vision, or less ordinary source material. The pre-Opus testing checklist is designed for exactly that decision.

If you want higher quality, faster processing, or broader format support, Opus does not meet that expectation; if you want to keep converting without counting successful conversions, that is exactly what the purchase changes.

7. Boundaries: what this purchase does not buy

The clearest way to understand Opus is to separate the paid entitlement from the product's technical boundaries. The following limits are the same in the free version and in Opus:

If one of those items is the main reason you were considering the purchase, treat it as a reason to test carefully rather than assume Opus changes the limitation. If you have already used the free conversions on your normal files and the results suit you, but you simply do not want to keep counting successful conversions, then the paid value is straightforward.

Frequently Asked Questions

Does CineX Opus charge me every month?

No. Opus is a one-time purchase, not a monthly or annual subscription, and it does not auto-renew. The price is US$8.99 in the U.S. and ¥38 in China.

Are US$8.99 and ¥38 two different versions?

No. They are regional prices for the same Opus purchase. In both regions, the paid entitlement is unlimited conversions; there is no separate quality, speed, or format tier.

Will my converted video look better after I buy Opus?

No. The free version and Opus use the same quality rules. Whether CineX can only adjust the container or needs a full conversion depends on the file itself, not on whether Opus has been purchased.

If I get a new iPhone, do I have to buy Opus again?

Not when you are using the same Apple ID. You can restore the purchase through the App Store on the new device and continue using the Opus purchase you already made.

So what is the actual difference between free and Opus?

The difference is the cumulative conversion count. The free version includes the first 5 successful conversions; after the one-time Opus purchase, conversions are unlimited. Quality, speed, format support, and known technical boundaries do not change because you paid.
