Frequently asked questions

What is Change video speed?

Speed a video or audio file up or down, hearing the result live before anything is encoded. The pitch follows or stays natural, your choice.

When would I actually use this?

Trimming a clip to the part that matters, pulling the audio out of a video, and converting to the format a platform will actually accept.

What is the most common mistake?

Re-encoding when a copy would do. Every lossy pass loses quality that no later step recovers, so trimming without re-encoding is always the better route when the format is already right.

How is Change video speed different from Burn subtitles into a video?

They sit next to each other but answer different questions: Burn subtitles into a video is the one to open when you need it to paint an SRT or VTT track into the picture, so it plays on any player. Pick whichever matches what you're starting from — both are free.

Is there a tool for the next step?

Mute a video is the closest one after this: Drop the sound track from a video without touching the picture.

What else is worth having open alongside it?

Resize Video and Rotate a video — they come up in the same task often enough to be worth a second tab.

Where do the figures come from?

Processing runs in the browser through a WebAssembly build of the same encoders desktop tools use, on a single thread. That keeps the file private and off any server, and makes long clips slower than a native application.

How-toRemoving the Sound From a Video Without Touching the PictureOne ffmpeg command, no encoder, and a result whose video stream is byte-for-byte the one you started with — verified by checksum. Plus why the file barely shrinks, and the difference between a silent track and no track at all.GuidePulling Still Frames Out of a Video — and Why They Look Softer Than the Video DidThree commands hide behind three buttons: one frame at a timestamp, a fixed number spread across the clip, or one every N seconds. Here are the exact arguments, the 60-frame ceiling and the reason a frame from the middle of a compressed clip can never be as sharp as a keyframe.ExplainerRotating a Video 90° or 180°: the Flag or the PixelsThere are two completely different ways to turn a video, and only one of them touches the picture. This tool takes the slow, lossy, universal road — and there is a good chance your sideways phone clip does not need it at all.GuideWhy a Three-Second GIF Outweighs the Video It Came FromA GIF has no real video compression: every frame is a whole picture, capped at 256 colours. That gives you an arithmetic you can do in your head — width times height times frames — and three levers to pull when the upload box says the file is too big.GuideWhich Video Resolution to Choose, and What Each Step Costs in MegabytesGoing from 1080p to 720p does not halve the picture: it removes 56 % of the pixels, and it removes rather less than that of the file. Here is the ladder with real pixel counts, honest bitrates and what three minutes weighs at each rung — plus the reason a low-bitrate source barely shrinks at all.How-toGetting a Video Under an Upload Limit Without GuessingThe quality slider cannot aim at a file size — that is not what it is for. But the limit and the length of your clip already fix the bitrate you are allowed to spend, and one division tells you whether the resolution you are using can possibly fit.
