Free Online Video Frame Rate Converter
Use the frame rate converter to export video at 12, 15, 24, 25, 30, 50 or 60 fps. Match a delivery specification while keeping the action at its original pace.
How to use the frame rate converter
- Check the frame rate your editor or playback system needs.
- Open the clip and select the matching value in frames per second.
- Export the video and check its frame rate in your player’s media information.

Choose the frame rate required for delivery
Start with the playback or editing requirement. If the receiving project needs 25 fps, select 25 in the frame rate converter. If the project accepts your original frame rate and already plays smoothly, there may be little to gain from another export. Open the original file’s media information and look for the value in fps. The refresh rate displayed in the settings of your laptop or phone describes the screen and can be different from the rate recorded in the video.
For a project with several cameras, check each source separately. Two recordings can have the same dimensions and very different timing. One may contain 25 pictures per second while the other has 50. If the final project is 25 fps, the conversion of the second source discards some pictures to fit that cadence. Reducing the height of the picture would change a different property and would not solve a frame rate mismatch.
Use the exact value requested by your destination. This frame rate converter offers whole-number rates. If the specification says 23.976 or 29.97 fps, selecting 24 or 30 is a different timing choice. Ask whether the whole-number rate is accepted before delivering a long recording. The digits after the decimal point matter when an editing system expects to line up pictures with a precise sequence of timecodes.
What happens to motion when the rate changes?
At a lower output rate, fewer pictures fit into each second. In a 60 fps source converted to 30 fps, about half the source frames are represented in the result. A mostly static slide may look nearly identical. A ball moving quickly across the frame can appear to jump farther between positions. Pause on the motion and step through the downloaded clip to see the difference.
At a higher rate, the frame rate converter can repeat source pictures to fill the additional output intervals. A 30 fps clip exported at 60 fps can have twice as many output frames without recording any new positions between the old ones. The extra frames do not reveal what happened between two exposures. If you need genuinely finer motion for slow playback, start with footage captured at a higher frame rate so you have more distinct images to play back.
When the input and output rates are not simple multiples, repeated or discarded pictures can fall at uneven intervals. A slow camera pan past closely spaced vertical lines makes this particularly visible. Compare the same section before and after conversion at normal playback speed. If the original is already jerky at that point, inspect the camera capture before trying another whole-number setting.
When to use a frame rate converter or a speed control
Frame rate tells you how often pictures are displayed. Playback speed tells you how much recorded time passes during one second of viewing. The frame rate converter changes the picture cadence while the event keeps its timing. A speaker should finish the same sentence at roughly the same moment. Small differences at the last frame can come from fitting the end of the clip to a new frame interval.
If you want a ten-second action to take twenty seconds, choose the speed tool and select half speed. For an editor that requires thirty frames each second while the action still lasts ten seconds, use the frame rate converter and select 30 fps. When both adjustments are needed, decide the intended running time first. Save the source separately so that you can return to the original pictures if the editor changes the specification.
After saving, look at the frame rate reported for the downloaded file. Then listen to a passage where a short sound matches a visible action, both near the beginning and near the end. A correct number in the media information does not by itself tell you whether a pan looks acceptable, a screen cursor remains visible or the final word is still in sync.
Frame rate converter questions
Does 60 fps make an old recording smoother?
The frame rate converter can write a file with sixty output frames per second. If the camera captured only fifteen distinct pictures each second, there are still only fifteen original views of the action. Repeated frames can satisfy a player’s required rate, but they cannot recreate a missed movement or remove blur from a long exposure.
Which setting should I choose for a screen recording?
Check what the viewer must see. A static slide changes very little, while a cursor tracing a path or a rapidly scrolling list can become difficult to follow at twelve frames per second. Export a short representative section and look for the cursor at the moment the viewer needs to click.
Does a lower frame rate guarantee a smaller download?
File size also depends on dimensions, motion, duration, the soundtrack and the encoding. A file with fewer pictures can still be larger than a highly compressed source. Use a size target in the compressor when a receiving system limits the number of megabytes, and check the actual saved file.
Can I use this frame rate converter on a variable-rate recording?
If the recording can be decoded, selecting an output rate gives the export a regular picture cadence. Check a section with rapid changes as well as a quiet section. If the source has missing pictures or a broken timeline, changing the output rate alone cannot reconstruct what the device failed to capture.
