Video Bench

There is a slight trade-off between file size and quality, but the medium setting usually retains excellent visual fidelity while shrinking the file.

Since everything runs locally in your browser memory, it depends on your device's available RAM. For best results, keep inputs under 2GB.

Not necessarily. If you choose a high bitrate, the quality remains nearly identical to the original.

Yes, MP4 is highly compatible across all operating systems and is the recommended output format.

The tool trims as close as possible to the specified keyframes, usually within a fraction of a second.

No, it typically only re-encodes the segments near the cut points, making it much faster than a full render.

The MP3 is typically exported at 192kbps or 320kbps depending on your selection, ensuring high quality.

If your browser supports reading the MKV container, the FFmpeg engine can extract the audio just fine.

GIF is an older format without advanced compression. Reducing the framerate or resolution helps keep the size down.

It's best to trim the video first using the Trim tool, then upload that trimmed clip here.

No, the video stream is simply copied over without the audio stream, so visual quality is perfectly preserved.

This tool mutes the entire file. For partial muting, you'd need the advanced Video Editor.

Yes, despite having timeline controls, all editing logic runs in your browser via WebAssembly.

Currently, the editor focuses on single-track manipulation for quick, focused edits.

It doesn't have to be, but a transparent PNG works best for logos and watermarks.

This tool currently applies static images uniformly across the video's duration.

Not if you check the 'preserve aspect ratio' option, which will add black bars if necessary instead of stretching.

Yes, but upscaling cannot add missing detail, so the result might look slightly blurry.

Yes, on most modern browsers you can check a box in the sharing dialog to include system audio.

It is stored temporarily in your browser's memory using Blob objects.

No, because the text is 'burned' into the video pixels, it acts as an image. Use subtitles for accessibility.

Yes, you can use line breaks to create blocks of text.

No, the tool joins the end of the video perfectly to the beginning of the next iteration.

Yes, because the final file is physically longer and contains more data.

The voices depend on the synthesis engine built into your specific browser and OS.

Since it uses system voices, commercial rights depend on your operating system's terms of service.

No, it uses a blurring algorithm to interpolate surrounding pixels, obscuring the logo heavily.

Currently, the tool applies a static rectangular blur across the entire duration of the clip.

If you boost it too high beyond the digital ceiling, it will clip and distort. Increase it in small increments.

Yes, setting the volume to 0% works, though the Mute tool is faster for that specific task.

For the best results, yes. If they differ, the tool will attempt to scale them to match the first video.

The only limit is your browser's memory capacity. Sticking to 5-10 short clips works best.

Yes, because you are physically removing pixels from the edges, the overall resolution of the output file will be smaller.

Absolutely, just adjust the bounding box to a vertical aspect ratio like 9:16.

If your original video is 30fps and you slow it to 0.5x, it plays at 15fps, which may appear slightly choppy. 60fps footage is better for slow motion.

The audio will pitch down (sound deeper) when slowed, and pitch up (sound like a chipmunk) when sped up.

Yes, rotating a 1920x1080 landscape video by 90 degrees turns it into a 1080x1920 portrait video.

Smartphones sometimes use metadata to tell players to rotate the video. This tool permanently bakes that rotation into the pixels.

To counteract camera shake, the software has to move the frame around. It crops the edges so you don't see black borders dancing around the frame.

It works best on micro-jitters. Wild, sweeping shaky camera movements might result in weird warping artifacts.

The tool will typically truncate the audio stream to match the length of the video stream.

Yes, this tool is designed to replace the existing audio track entirely.

Yes, rotating turns the image, while flipping mirrors it. Flipping text will make it appear backwards.

Vertical flipping is rarely used for standard correction, but it can create interesting abstract reflections for creative projects.

It typically records in your webcam's native resolution, often 720p or 1080p.

Yes, if you use a mobile browser that supports the MediaRecorder API, it will utilize your phone's front or back camera.
