A website's native video text track normally needs WebVTT rather than an SRT file that happens to work in a desktop player. Check format, track declaration and public loading separately. Renaming the extension to .vtt does not convert SRT syntax, and a valid caption file can still fail to load.
Confirm the intended caption path
Determine whether the page uses a native HTML video element, a hosted platform player or another library. Those systems can have different caption import workflows. Inspect the published page's actual player instead of assuming a file uploaded elsewhere is automatically connected.
MDN's track-element documentation describes WebVTT sources, language declarations and same-origin requirements unless the parent media element is configured for cross-origin use. This concerns the browser's track mechanism; it does not imply that every third-party video embed accepts the same markup.
Check the file as text
A WebVTT file begins with the appropriate header and uses its own cue timing syntax. Compare the first cue with the source audio and confirm that text encoding preserves the intended characters. Use a real format conversion or supported caption export rather than editing the filename alone.
Keep the original SRT and a separately named VTT candidate. Start with a short reviewed cue on a duplicate or test page. This isolates a loading problem from an error buried in a long caption file.
A hypothetical tutorial page
Suppose an SRT displays correctly in the editor, but the published tutorial has no captions. The producer creates a valid WebVTT copy, connects it through the actual player's supported track path and checks that the caption menu exposes the intended language.
If it still fails, inspect whether the caption URL returns the text file, a login page or a missing-file response. For a different origin, inspect the applicable cross-origin configuration rather than making private files public indiscriminately. This is a hypothetical diagnostic path, not a tested implementation of a particular website.
Verify loading and viewing separately
Use the browser's network and console tools where available to inspect the caption request. A successful HTTP response that contains HTML is not a valid caption response. Conversely, a loaded track may remain hidden until the viewer selects it. Check cue timing against the media's actual start and test the intended browser and mobile view.
Accept when authorized viewers can load and select the correct track, the first and later cues match the film, and characters are readable. Reject a setup that works only in a logged-in editor preview or serves the wrong file. Preserve the source captions and published-track version together. These are external website integration checks, not a promise that Imagild automatically hosts or configures captions for an unrelated site.
