Introduce a video with a title image

Prepare a readable image

Use a short title such as “A table stuck in a PDF?” to introduce the demonstration. Large lettering, clear contrast and generous margins matter when viewers watch on a phone. An opening title introduces the subject; it does not replace captions for speech in the video.

Choose a still JPG, PNG or WebP. The entire image is centred without stretching or cropping. Different proportions produce black bars, and transparent areas become black. An image with the same proportions as the video avoids bars. Once you import the video, the preview shows the actual opening frame.

Set the timing and create the MP4

1. Choose your image and video, or try the built-in example.
2. Set the intro between 1 and 10 seconds, in 0.1-second steps.
3. Create the MP4, check the transition and download.

Timing applies only to the image. A 3-second title followed by a 20-second video produces about 23 seconds altogether. Nothing is cut from the beginning of your video: the image is added before it. Try 2 or 3 seconds for a short demo, then check that the title can be read comfortably.

The introduction is silent. Video sound begins after the image, when the original video starts. Only the first audio track is kept and re-encoded to stereo AAC. A video without an audio track remains silent. There is no added music, mixing or automatic subtitling.

Choose a direct cut, fade through black or crossfade. Fade through black darkens the end of the image and beginning of the video. Crossfade starts after the chosen intro time and overlaps the beginning of the video for up to 0.5 seconds. For clips shorter than one second, the fade is shortened. Total duration stays image + video; sound starts after the image duration, with no audio fade.

Check the copy before sharing

Watch the first second, the transition into the video and a passage near the end. Listen to the beginning of the voice too: it should start with the video, not over the title. Output is re-encoded as H.264 MP4 at 30 fps, so appearance and file size can change. Video proportions are preserved; odd dimensions are rounded down to an even pixel count. Keep the original.

This first version accepts an image up to 10 MiB and 16 million pixels, and a video up to 50 MiB, one minute, 1,920 pixels per side and 60 fps. MP4, MOV and M4V require H.264 video; WebM requires VP8 or VP9. HEVC, HDR and offset tracks are rejected. Output is limited to 64 MiB. The roughly 32 MB engine loads on the first video import. A recent computer is recommended; physical phone performance has not been qualified.

Files are processed in your browser. A failed import or cancellation keeps previous files and the last successful download. Changing the image or timing marks that download as an earlier result until you create a new one. Download before closing, reloading or changing language.
