## What is FrameSmoother?

Turn choppy video into smooth 60 or 120fps, or slow it down without the stutter. FrameSmoother computes the new frames with AI right on the phone.

Slow motion that stays smooth
Slow it down by up to 8x. Instead of repeating frames, the app generates the in-between frames, so motion stays fluid even at 8x.

Features:
- Convert to a target frame rate (60 / 120fps) or by a multiplier (2x / 4x)
- Slow motion up to 8x
- Trim: process only the part you choose
- Anime: remove duplicate frames from anime drawn on twos or threes, then fill in the motion between drawings
- Two quality modes: High Quality (AI) and Fast (no AI)
- Queue up to 5 videos; they are processed one after another
- Before/After comparison slider with frame-by-frame scrubbing
- Export as mp4 or mov, save to Photos or share with AirDrop

Privacy:
Videos are processed locally and are not uploaded. FrameSmoother gathers no data.

Pricing:
Every feature is included in a single one-time purchase, without a subscription or ads.

Requirements:
- iOS 16 or later

### 1/5 — 拉完了，不知道评论区怎么发视频，但是我把帧率清晰度全调到最高以后啥也看不清，帧率甚至可能只有30帧。我刚买了5分钟发起退钱也不给退，垃圾软件，骗钱的

**Developer response:** Keine；Ahnung 您好：

非常抱歉让您失望了，也感谢您告诉我们具体的情况。

关于退款：App Store 的购买和退款由 Apple 处理，开发者看不到订单，也无法办理退款。您可以登录 reportaproblem.apple.com，选择这次购买并申请退款；如果未获批准，也可以联系 Apple 支持。

关于"帧率好像只有 30 帧"：iPhone 的"照片"App 可能会把 120fps 的视频当作慢动作视频播放，把中间部分放慢，这时每秒显示的画面大约只有 30 帧。我们已发布 1.0.11 版本，针对这个问题进行了处理：超过 60fps 的输出即使选择了 MP4，现在也会保存为 .mov（编码仍为 H.264），并在文件中写入以正常速度播放的信息。请更新到 1.0.11 或更高版本后重新转换视频。用旧版本转换的视频没有这项信息，仍可能被当作慢动作播放。对于这些视频，可以在"照片"中打开并轻点"编辑"，把视频下方带竖线的慢动作条两端拖到一起并轻点"完成"，即可按正常速度播放。也可以在 FrameSmoother 中把输出帧率改为 60fps（60fps 的视频不会被当作慢动作）。如果更新后新转换的视频仍然变慢，请通过下面的邮箱告诉我们。

关于画面看不清：补帧是在原有画面之间生成新的画面，动作很快或画面变化很大的场景可能会出现模糊或重影。评论区无法上传视频，如方便，请把设备型号、原视频的帧率和分辨率、所选的设置，以及效果不好的视频发送到 konpei.work@gmail.com，我们会仔细查看。

Hi Keine；Ahnung,

We're very sorry to have let you down, and thank you for describing what happened.

About the refund: App Store purchases and refunds are handled by Apple. Developers can't see orders or issue refunds. You can sign in at reportaproblem.apple.com, select this purchase and request a refund; if it isn't approved, you can also contact Apple Support.

About "it looks like only 30 fps": the iPhone Photos app may play 120 fps videos as slow-motion videos, slowing down the middle part; while it's slowed down, only about 30 frames are shown per second. We've released version 1.0.11 with a change that addresses this: output above 60 fps is now saved as .mov even if you choose MP4 (the codec stays H.264), and the file includes information asking for playback at normal speed. Please update to 1.0.11 or later and convert your video again. Videos converted with earlier versions don't have this information and may still play in slow motion. For those videos, open the video in Photos, tap "Edit", drag both ends of the slow-motion bar with vertical lines below the video together, and tap "Done" to play it at normal speed. You can also choose 60 fps as the output frame rate in FrameSmoother (60 fps videos aren't treated as slow motion). If a video converted after updating still slows down, please let us know at the email address below.

About the blurry image: frame interpolation creates new frames between the original ones, so very fast motion or big changes between frames can look blurry or show ghosting. Reviews can't include videos, so if you can, please email konpei.work@gmail.com with your device model, the original video's frame rate and resolution, the settings you chose, and the video that didn't look right, and we'll take a close look.

## Frequently asked questions about FrameSmoother

### How does FrameSmoother create smooth video?

FrameSmoother uses AI to compute and generate in-between frames for your video. This process creates smoother motion compared to simply repeating existing frames, especially for slow-motion effects or frame rate conversions.

### What are the slow motion capabilities of FrameSmoother?

FrameSmoother allows you to slow down videos by up to 8x. It generates new frames to maintain fluid motion, preventing the stutter often seen in traditional slow-motion.

### Can FrameSmoother convert videos to higher frame rates?

Yes, FrameSmoother can convert your videos to a target frame rate of 60fps or 120fps. It can also apply multipliers like 2x or 4x to increase the frame rate.

### Is FrameSmoother available on Android devices?

FrameSmoother is currently only supported on iPhone devices running iOS 16 or later.

### How much does FrameSmoother cost?

FrameSmoother is a one-time purchase priced at $1.99. There are no subscriptions or ads included with the purchase.

### Does FrameSmoother have ads?

No, FrameSmoother is ad-free. The app is a one-time purchase and does not contain any advertisements.

### How often is FrameSmoother updated?

The latest version of FrameSmoother is 1.0.12, which was last updated on October 20, 2026. Updates typically address performance improvements and feature enhancements.

### Is my video data safe with FrameSmoother?

Yes, your video data is safe. All video processing is done locally on your iPhone, and FrameSmoother does not upload or gather any user data.

## Version history (last 5 releases)

### 1.0.12 — 2026-10-20

Features added in recent updates are now shown on the App Store page:
• Slow motion at 2x / 4x / 8x. In-between frames are generated rather than repeated
• Trim: process only the part you choose
• Anime: remove duplicate frames from anime drawn on twos or threes

### 1.0.11 — 2026-10-13

问题修复：
• 针对以 120fps 等帧率转换的视频在“照片”中播放到一半可能变成慢动作的问题进行了处理。保存为 .mov 的视频现在会包含以正常速度播放的信息
• 因此，超过 60fps 的输出即使选择了 MP4，现在也会保存为 .mov（仍为 H.264）。60fps 及以下的输出仍按所选格式保存

### 1.0.10 — 2026-10-05

问题修复：
• 修复了完成 App 内购买后功能仍未解锁、付款界面持续显示的问题
• 使用“恢复购买”时，如果未找到购买记录，现在会显示提示

### 1.0.9 — 2026-09-26

Bug fixes:
• Converted videos now keep the sound of the original video. Until now the audio was dropped and the output was silent
• "Stop All" now also stops the video that is currently being processed, not just the ones waiting in the queue

### 1.0.8 — 2026-09-23

Any video now converts to exactly 60fps — or 120fps if you choose. Until now only footage shot at exactly 30fps came out at 60fps; 24fps, 25fps and 29.97fps video ended up at 48, 50 and 59.94fps. Pick a target frame rate on the setup screen, or switch to Multiplier to keep the original frames.

Also fixed:
• Video shot at 59.94fps now converts to 60fps instantly, with no loss of quality
• 4x on 60fps video wrote a 240fps file even though the app showed 120fps
• Slow-motion video (240fps) always failed to export at 4x
• Generated frames looked blocky because the bit rate did not rise with the frame rate
• The setup screen appeared in English in every language
