Choose a video format and troubleshoot browser exports

TypographyEdit offers mobile 9:16 at 1080 × 1920, laptop 16:9 at 1920 × 1080, and tablet 4:3 at 1024 × 768. The ratio describes the frame's shape; the dimensions describe the output pixel grid. Choose mobile for a vertical presentation, laptop for a wide presentation, and tablet when a less elongated composition suits your material.

Set the format before refining the layout. A landscape phrase may fit on one line but need several lines in portrait. When converting an existing edit, inspect every scene after changing the format. Check long words, accent boxes, and the space around the main phrase. Reusing the same script is useful, but the final composition still needs a separate review.

Before building a long sequence, make a short video and export it on the device you plan to use. This checks browser video-encoding support and gives you a realistic sense of rendering speed. A recent desktop browser is a sensible starting point; support depends on the browser and device, so successful preview playback does not guarantee successful encoding.

An MP4 export renders frames on your device. Keep the tab open and avoid switching away on mobile devices that may suspend background tabs. Close other resource-heavy applications if the device is struggling. Downloading requires enough available storage for the resulting file. Start with a shorter script if the first attempt consumes too much memory or takes too long.

If the editor reports that browser rendering is unsupported, try a current browser with compatible video encoding. If rendering begins and then fails, shorten the sequence and retry. If rendering completes but you cannot find the file, inspect your browser's download list and configured download folder. These cases have different causes, so note the exact message instead of repeatedly pressing export.

SRT is a text-based caption file, separate from the MP4. Use the editor's SRT download when you need timed captions for another application. It is not a video and should not be opened expecting animation. After importing it into a destination editor, check the caption timing against your final video, especially if you changed scene durations or trimmed the MP4.

If a short export still fails, record your browser version, operating system, selected template, format, approximate script length, and the error shown. Explain whether the preview worked and whether the failure happened before rendering, during rendering, or at download. These details narrow the problem much more than a report that says only ‘export is broken’.

Use the contact page to send the report. Include a small non-sensitive example script if the problem seems tied to a specific phrase. Do not include passwords, access tokens, or confidential material. A screenshot of the message is useful, but keep personal information out of it. Save your downloaded files and any script you need elsewhere; a browser session is not a permanent backup.
