FFmpeg eq and curves paint one look. Cinematic lowers saturation and uses a cross process curve. Cool lifts blue. Warm lifts red. Width and height stay the same. The soundtrack stays when the file has one. Clips up to 30 seconds. A photo belongs on the image pages.

Pick cinematic, cool or warm, then download MP4. The frame size stays. The soundtrack stays when the file has one. The work runs in this tab.

How to grade a short video

1. Drop a video you already have. A photo or an audio file is refused here. 2. Leave cinematic, or pick cool or warm. 3. Press “Apply grade” and download the MP4.

GustKit runs the FFmpeg eq filter and then curves. Cinematic lowers the saturation and uses the cross process curve. Cool lifts the blue. Warm lifts the red. Width and height stay the same. A soundtrack is encoded again in AAC and stays in step.

A look, not a brightness slider

Video brightness, contrast and gamma each move one control. This page applies a whole look: contrast, saturation and a curve together. It does not crop the frame and it does not change the speed.

The video stays in this tab

FFmpeg runs in this browser, on one thread. GustKit does not fetch a video from a link. Leave the tab open until the download appears. Close it and the file is gone. Clips up to the limit shown next to the button.

How to check the grade

1. Play the download next to the original. 2. A gray patch should pick up a tint. Warm should push red. Cool should push blue. 3. If the download is not MP4, or the frame size changed, you opened a different page.

Video contrast moves one control. This page runs FFmpeg eq and curves as one look and saves MP4. Nothing is uploaded.

Frequently asked questions

The download is MP4 and a gray frame picked up a tint. Did it work?

Yes. Warm pushes red above blue. Cool pushes blue above red. Cinematic shifts the middle toward the cross process look. Width and height stay the same.

Why is the file MP4 even if I dropped a WebM?

The grade re-encodes every frame. The download is H.264 in an MP4 so it plays in more places.

Can I grade a clip and also change only the contrast in one step?

No. Apply the grade first, or change the contrast first, then open the other page on the download.

Is the video uploaded?

No. The grade runs in this tab.

A gray frame came back warmer and the frame size matches. Did it work?

Yes. Warm lifts red above blue. Width and height stay the same. The soundtrack stays when the file has one.

Can I grade a clip and also change only the brightness in one step?

No. Apply the grade first, or change the brightness first, then open the other page on the download.
