Turn a GIF into a looping MP4

• Acceptance. Social apps and video editors are built around video files. A GIF may be refused, turned into a still image, or converted on upload in ways you cannot control. An MP4 goes in as it is.
• Length. Some places want more than a couple of seconds of video, and a short animation can feel abrupt in a feed. Repeating it fills the time without changing the animation.
• Sound. A GIF is silent by design. As an MP4 it can carry a song or a voice-over.
• Playback control. Video players offer pause, scrubbing and full screen, and a video sits on a timeline next to other clips in an editor, which a GIF often cannot.

Converting does not improve the picture. A GIF has at most 256 colours per frame and is often small; the MP4 keeps exactly those colours and dimensions. If you still have the original video the GIF was made from, loop that instead for a sharper result.

There are two ways to stretch a GIF, and they suit different jobs.

• Length fills a duration: 30 s, 1 min, 10 min, 30 min, 1 hour, or any custom length up to three hours. The final pass is cut so the video ends exactly on time. Use it when a platform or project needs a specific length.
• Number of times plays the GIF a set count, anything from 1 to 999. Use it when the animation should play, say, three times and stop at a natural ending.

Long files stay manageable: the loop is encoded once and written again for every repeat, so even an hour-long video of a tiny GIF finishes quickly. If you are padding a clip to reach a minimum length, making a video longer compares looping with other approaches.

A GIF does not have a frame rate in the usual sense. Each frame stores its own display time in hundredths of a second, so an animation can hold one frame for a second and flash the next for a few hundredths. That uneven rhythm is part of many GIFs’ character, and it is why a GIF can look slightly different from one viewer to another. Browsers, for example, slow down frames with extremely short delays.

• Check the motion with Play loop (Space) before exporting. There is no speed control, so a GIF that runs too fast or too slow stays that way.
• MP4 has no transparency. Any see-through parts of the GIF become a solid background in the video.
• GIFs that were themselves cut from a video often jump at the restart. Find the best loop can choose a cleaner start and end within the GIF, and a short Crossfade hides what is left; the seamless loop video page explains the options.
• Very small GIFs stay small. Size under Export settings offers the original size or smaller, never larger, so the platform will scale it up when it is shown.

Since a GIF has no sound of its own, music is the natural partner. After Choose music, set Music start and Music end to pick the section of the song you want, add Fade in and Fade out so it does not start or stop abruptly, and set the Volume.

If the video runs longer than the song, switch on Repeat the music so the track starts again. Or let the song set the length: Until the music ends loops the GIF for exactly as long as the trimmed track. More on this in loop a video with music.

Use music you have the right to use, especially for anything posted publicly; platforms may mute or block tracks they recognise.

GIFs come in every shape. Under More options, Shape crops to 9:16 for Reels, TikTok and Stories, 4:5 or 1:1 for a feed post, or 16:9 for landscape. Drag the preview, or use Position, to choose what stays in the frame. The Instagram loop video page has more on fitting each format.
