Common Frame Rate Conversions
Here are the most searched frame rate conversion combos, explaining what actually happens in each case, how file size changes, and when you'd want to do it.
60fps to 30fps
The most common way to lower frame rate. It evenly drops half the frames, keeping duration and speed unchanged, and usually cuts file size by 30-50%. Great for slimming down gameplay or screen recordings before uploading.
30fps to 60fps
Fills in duplicate frames to reach 60fps. This won't make the motion any smoother, but it can satisfy a platform's or editing timeline's 60fps requirement, and makes it easier to splice with other 60fps footage.
30fps to 24fps
Converts a standard web video frame rate to cinematic frame rate, giving the footage a narrative feel. Great for vlogs, short films, and promo videos in post, with a slight reduction in file size too.
24fps to 30fps
Brings cinematic footage in line with the web standard, avoiding pacing mismatches when cutting it together with 30fps clips. A routine prep step before combining multiple clips.
60fps to 24fps
The biggest jump in frame rate reduction, going straight from high smoothness to a cinematic feel. Action scenes will show noticeable cinematic motion blur, and file size drops the most.
120fps to 60fps
Phone slow-motion mode often produces 120fps footage. Converting to 60fps keeps duration and speed unchanged (it won't turn into slow motion), but improves compatibility and halves the file size.
25fps (PAL) to 30fps
Unifies PAL-standard European footage to 30fps. Mixing different standards in a long video can cause audio-video drift over time, which unifying beforehand avoids.
29.97fps (NTSC) to 30fps
Rounds off the non-integer frame rate inherited from NTSC. Visually there's almost no difference, but it eliminates accumulated audio-video drift and timecode headaches in long videos.
Down to 15fps or lower
Commonly used for archiving surveillance footage, tutorial demos, and preprocessing before making a GIF. File size drops dramatically, at the cost of noticeably choppy motion.
Recommended Frame Rates by Platform
Different platforms support and recommend different frame rates. Setting the frame rate to a platform's recommended value before uploading avoids quality loss from the platform's own re-encoding.
| Platform | Recommended Frame Rate | Notes |
|---|---|---|
| YouTube | 24 / 30 / 60fps | Broadest support, up to 60fps. It's best to keep the same frame rate you shot at, rather than converting just for the upload. |
| Douyin / TikTok | 30fps or 60fps | 30fps is a safe choice, and 60fps looks better for action content. Below 24fps, footage tends to get flagged as low quality. |
| Bilibili | 30fps or 60fps | 60fps is common for gaming and action content; 30fps is plenty for general content and saves considerable upload time. |
| Instagram Reels | 30fps | The platform compresses high-frame-rate footage down to 30fps anyway, so converting it yourself first avoids an extra lossy re-encode. |
| WeChat Channels / Moments | 25 / 30fps | File size limits are fairly strict here, and dropping to 30fps is often the key step to getting a video to post successfully. |
| X (Twitter) | 30fps or 60fps | Supports up to 60fps, but the file size cap is lower, so 30fps clears it more easily. |
| Cinema / Short Film Screening | 24fps | The film industry standard frame rate, and the source of that classic "cinematic" look. |
To shrink a file, should I change the frame rate, bitrate, or resolution?
All three parameters can reduce file size, but the trade-offs are completely different. Adjusting them in the order below usually gets you the best balance between size and visual quality.
Lower the bitrate first — the biggest gain for the smallest cost
Bitrate directly determines how much data is written per second, so its effect on file size is nearly linear. Most phones and screen recorders default to a much higher bitrate than actually needed, so cutting it in half is often visually indistinguishable.
Then lower the resolution — nearly lossless for phone viewing
Dropping from 4K to 1080p can cut file size by more than half, and the difference is basically invisible on a phone screen. Only keep the high resolution if you need to play it on a big screen or crop it further later.
Lower the frame rate last — only worth it for high-frame-rate footage
Going from 60fps to 30fps usually only cuts file size by 30-50%, at a real cost to motion smoothness. So it's best suited to footage that's already 60fps or higher, like gameplay or screen recordings; if your footage is already 30fps, there's no point going lower.
If your only goal is a smaller file, try a compression tool to adjust bitrate, or a resolution tool to resize first — that's usually a better trade-off than lowering the frame rate.
What frame rate should I use? Look it up by goal
If you're not sure which frame rate to pick, figure out the outcome you want first, then find your target in the table below.
I want a cinematic look
Convert to 24fps
The film industry's standard frame rate, its motion blur gives footage a narrative feel.
I want the file small enough to send on WeChat
Compress the bitrate first; if it's still too big, drop to 30fps
Lowering the frame rate is the last resort — adjusting bitrate first pays off more.
I want the action clearer in a game recording
Keep 60fps, don't lower it
A high frame rate is exactly what makes action content valuable.
I'm cutting multiple clips into one timeline
Unify everything to the same frame rate (usually 30fps)
Mismatched frame rates can cause editing software errors or audio-video drift.
A platform says my video's frame rate isn't supported
Convert to 30fps
30fps is the most universally compatible value.
I'm turning a video into a GIF
Drop to 10-15fps first
The fewer frames a GIF has, the smaller it is — 15fps is already enough to convey motion.

Frequently Asked Questions
Does adjusting the frame rate affect video quality?
Adjusting the frame rate does not directly degrade quality. Lowering it reduces frames per second (which may look slightly less smooth), while raising it fills gaps with duplicate frames (no new visual information is added). We use high-quality encoding settings to minimize any quality loss.
How do I convert a 60fps video to 30fps?
Upload your video, click the "30 fps" preset button, then click "Convert". The tool will automatically reduce the frame rate from 60fps to 30fps, and the file size should decrease by roughly 30–50%.
What's special about 24fps?
24fps is the standard frame rate used in theatrical films. Its distinctive motion blur creates the iconic "cinematic look." Converting your video to 24fps is great for short films, storytelling Vlogs, and any content with a cinematic aesthetic.
Will my video files be uploaded to a server?
No. All video processing happens locally in your browser — your file is never uploaded to any server. Your video data stays entirely in your hands.
What input formats are supported?
Most common video formats are supported for input, including MP4, WebM, MOV, MKV, and AVI. Output can be saved as MP4, WebM, or MOV. We recommend using Chrome or Edge for the best WebCodecs hardware acceleration support.
Why would I reduce game recording videos to 30fps?
Game recordings are often 60fps or higher, resulting in very large files. Reducing to 30fps significantly shrinks file size, making it easier to upload to social platforms or share with friends — and 30fps is perfectly smooth for most viewing scenarios.
Does raising 30fps to 60fps make a video sharper?
No. Raising the frame rate just duplicates existing frames to hit the target rate — it doesn't create any new image information, so sharpness and smoothness don't actually improve. The real point of raising frame rate is standardization: aligning multiple clips on an editing timeline, or meeting a platform's 60fps upload requirement. To get genuinely smoother motion, you need to record at a high frame rate in the first place.
Does converting the frame rate change the video's duration?
No. This tool keeps the duration unchanged when adjusting frame rate: it evenly drops extra frames when lowering the rate, and inserts duplicate frames when raising it, so playback speed and total length always match the original. What actually changes duration is speed adjustment, which is a different operation.
What's the difference between 29.97fps and 30fps?
29.97fps is a legacy frame rate from the NTSC TV standard, born from an early technical compromise for color signals; 30fps is a round number. The two are nearly indistinguishable visually, but mixing them in a long video can cause audio and video to gradually drift out of sync. If your footage comes from different devices, it's best to convert everything to 30fps before editing. Likewise, Europe's PAL standard runs at 25fps and should also be unified.
What frame rate do phone-shot videos usually have?
Most phones record at 30fps by default, many models offer a 60fps option, and some support a 24fps cinematic mode; slow-motion mode typically shoots at 120fps or 240fps. Once you upload a video, this tool automatically detects and displays its original frame rate, so you don't need to dig through camera settings yourself.
Does converting 120fps to 60fps turn it into slow motion?
No. This tool only changes the frame rate, not the playback speed — converting 120fps to 60fps keeps the duration and motion speed exactly the same, it just halves the number of frames per second, making the file smaller. A slow-motion effect requires "shoot at a high frame rate, play back at a lower one," which is a speed change, not a frame rate conversion.
Will audio and video go out of sync after conversion?
No. The audio track is kept exactly as is, and the video track is re-encoded at the new frame rate to stay aligned with it, so the durations match and no drift occurs. If the original video already had audio-video sync issues, conversion won't fix that.
To shrink a video file, should I lower the frame rate or the bitrate?
Lower the bitrate or resolution first, and leave the frame rate for last. Lowering the bitrate has the most direct, nearly linear effect on file size, resolution comes next, while lowering the frame rate gives limited savings (going from 60fps to 30fps usually cuts only about 30-50%) at a real cost to motion smoothness. Lowering the frame rate is only worth it as the first move when the video is already gameplay or screen recording footage at 60fps or higher.
