The copy in three lengths is the tip I'd pass on to anyone doing a round of directories. I'd do the same for images: export the logo, a cover image and two or three screenshots once, in the sizes these forms ask for most, and keep them in the same folder as the copy doc. Two more columns that would help in your tracker. First, which screenshot set each listing uses. Listings that stay up for months will keep showing the old interface after a redesign, and the tracker is the only place that tells you which ones to update. Second, whether the form has a field for a video link. Some do, Product Hunt included, and having one short demo video ready makes those submissions copy and paste too.

One thing to watch when you try the fade: every frame of a fade changes every pixel, and a GIF's 256 colour palette handles gradients badly, so the file can grow a lot and the fade can show banding. A quick dissolve of a few frames is usually enough. Another option is to hold the last frame a little longer and then cut to a first frame that is almost empty, so the jump back is small without any extra frames. Good luck with the next release.

Holding the last frame for a beat or two is a good rule. It also gives people a moment to read the version number before the loop restarts. Do you add a fade on the replay or just cut back to the first frame?

Small and useful. Two checks I'd add to the manifest, since they cause most of the editor complaints I've seen. Frame rate, including whether it's variable: screen recorders often write variable frame rate files, and you can spot them when r_frame_rate and avg_frame_rate disagree in ffprobe. Editors drift audio sync on those. And duration with a tolerance, so a narration file that's a few seconds shorter than the picture gets flagged before anyone starts cutting.

Treating the banner copy like a commit title is a good rule. Two things I'd add from the reader's side. Hold the finished line on screen for a second or two before the loop restarts. People arrive mid-animation, and if the full message only sits there for a few frames, many of them read half a version number. And a looping GIF can't be paused, which some readers find hard while they work through upgrade steps. GitHub renders the picture element in Markdown (it's how light and dark mode images work), so a source with media="(prefers-reduced-motion: reduce)" pointing to a still PNG of the final frame should give those readers a static banner while everyone else gets the GIF. For releases that change the UI, I'd put a short silent clip of the change right under the banner. The banner says what changed, and the clip shows it.

Measuring real output sizes is the right call. Bitrate math tends to miss on screen recordings because most frames barely change. For those, one more option worth considering is a frame rate cap, like 15 or 30, applied before the search. A UI walkthrough rarely needs 60, and dropping frames often keeps text sharper at the same size than raising CRF does. With that and the no-audio flag, a README clip under a size limit gets a lot easier.

Letting the narration set the scene length is the right call, and it's the reason edits stay local. One catch with generated voices: regenerate the same line and the length often shifts by a few frames, which can move every scene after it. Storing each measured duration with a hash of the line text, and only re-measuring lines that changed, keeps timing stable between renders. The other weak spot is the screenshots. They go stale the moment the UI changes, so I'd capture them with a script, like a Playwright run against a seeded account, so refreshing every scene is one command instead of a manual pass.

The empty account walkthrough is the step I'd move to the top, because it feeds the landing page too. If you record that run with clean sample data, you get the screenshot of a meaningful result and a short clip of the first useful outcome from the same session. One more check for the screenshot item: open it at the size it will actually show on a phone. Labels that look fine on a laptop are often unreadable in a listing thumbnail. And I'd match the "known limitations" note to what the screenshot shows, so the visual never promises more than the copy.

Yes, the timing one is the hardest to catch by eye. The fix I'd suggest is cutting scenes to each language's narration instead of to the English edit, so every language gets its own scene lengths, with a minimum hold on any screen the viewer needs to read. On labels, if the UI isn't localised, keep the captions in the target language but write button names exactly as they appear in the app, in quotes. Then the words in the caption match what people will actually click.

Good question. I treat the flag as part of the fixture. The demo seed turns the flag on explicitly, so the end to end test for that flow and the demo read the same state, and nothing depends on whatever the flag service says that day. Two rules I'd add. If the feature isn't released to everyone yet, the video either says so on screen or waits. And the script never pulls steps from a test that only runs with the flag off. Otherwise you end up demoing a screen most users can't see yet.
