A pull request becomes a video

Video: pr-7.github.mp4 · 1920x1080 · 30 fps · 39.60 s · 9.4 MB, under GitHub's 10 MB attachment limit · -14.0 LUFS / -1.6 dBTP · no voice. The master pr-7.mp4 (11.8 MB, crf 22) is not kept here: the copy is the file to paste.

The Markdown to paste: pr-7.md, the heading and the line to drop the file on:

### What this pull request changes, in 40 s
<!-- drag pr-7.github.mp4 (9.4 MB) onto this line: GitHub uploads it and puts the video player here -->

The request#

"Turn showtime's pull request #7 into a short video I can paste into its description."

Mode: quick, no agent in the loop: showtime pr-video reads the PR, writes the project, checks, renders and exports by itself. PR #7 is showtime 0.3.5 (merged): fixes found by running showtime in a locked-down agent sandbox, 68 files, +1,138 -159.

On this machine gh was not signed in, so the PR was read beforehand and saved: gh pr view 7 --json title,body,number,author,url,additions,deletions,files,commits,baseRefName,headRefName as pr7.json and its diff as pr7.diff. --pr-json and --diff take those files instead of asking GitHub; with gh signed in (or for a public PR, GitHub's API without signing in) the command is just showtime pr-video 7.

What it made#

pr-video wrote one project in the release-video look, 8 scenes in 39.6 s, every word on screen from the PR:

The three cards are the bullets' bold leads, as written: "onnxruntime's telemetry was on, while PRIVACY.md says showtime has none.", "Site capture turned its private-address guard off for a site whose name did not resolve." and "Node downloads ignored HTTPS_PROXY." The description's opening paragraph is longer than one card, so it is left out, and so is its ## Checks section (evidence, not a change); "+ 8 more" counts the fixes not shown.

Secrets and private paths. pr-video masks lines that look like secrets (keys, tokens, .env values) before it writes anything and reports each one in project/pr.json ("masked"). Here the list is empty: the diff has no such line (it mentions .env files, never a value). Every frame was looked at for anything private: a sheet of one frame every 0.5 s (review/frames-every-0.5s.jpg, 80 frames) and ten frames at full size, one or two per scene. On screen there is the public repository, the public PR's words and code, a public URL and the author's public handle; no local path, machine or account.

Commands, in order#

showtime is skills/showtime/bin/showtime.

showtime pr-video 7 --repo FavioVazquez/showtime --pr-json pr7.json --diff pr7.diff
#   wrote pr-7-video/project: 8 scenes, 39.6 s; 3 of 11 description lines, 68 files, 2 hunks
#   check PASS (0 errors, 0 warnings, 0 notes); render; pr-7.github.mp4 (9.4 MB); the Markdown to paste
showtime qa pr-7-video
showtime qa pr-7-video/pr-7.github.mp4
showtime snap pr-7-video/pr-7.github.mp4 --every 0.5 --cols 8 --thumb 360    # the sheet of every 0.5 s

Timings#

On a 64-core Linux machine with no GPU, nothing else running: 40.8 s from the command to the files, of which the check took 15.3 s, the capture of 1,188 frames 8.6 s (8 browsers), the encode 3.1 s after it, then the mix and the GitHub copy. On a laptop expect a few minutes.

QA summary#

PASS (0 fail, 0 warn, 0 note), for the master and for the copy: -14.0 LUFS (target -14), -1.6 dBTP, no silent gaps, no black or frozen stretches, frame 0 has a picture, the repository name it must show is on screen 0.00-2.97 s; phone check PASS (smallest text 7.2 pt).

What the critic found#

Self-review of the first version (0.4.0's pr-video, 33.7 s): the review pack's critic brief answered in the session that made it (no separate critic agent ran on the build machine). Ship; would post: yes (review/FINDINGS.md). Both its findings were fixed in pr-video for 0.4.1, and the video here was made again with the same command (review/RESPONSE.md):

• Should-fix: 15.2 s (45 % of the video) went to the description's first sentence, cut into four cards and stopped by "…" before its last word, while the eleven fixes the PR lists in bold appeared only as "+ 15 more". Now the summary is three fixes by their bold leads (14.5 s, three cards), no card is cut off.
• Polish: "+ 15 more" counted lines (the ## Checks heading and its bullets too). Now "+ 8 more" counts the fixes not shown (11 in the description, 3 on screen).

Looked at again for this version: every frame on the 0.5 s sheet (review/frames-every-0.5s.jpg, 80 frames) and ten full-size frames; nothing private on screen, "masked": [] as before. One small thing: the second hunk ends on two empty added lines, shown as bare "+" rows.

Files#

• pr-7.github.mp4: the video to drag into the PR (under 10 MB); poster.jpg: frame 0.
• pr-7.md: the Markdown to paste, as pr-video printed it.
• project/: what pr-video wrote: index.html, pr.json (the PR as read, the plan, the scenes and masked), showtime.json, audio/mix.json (a generated bed, no downloads).
• review/: the self-review of the first version (FINDINGS.md, RESPONSE.md, the hearing pass audio.txt) and the frame sheet of this one.

To make it again: showtime pr-video 7 --repo FavioVazquez/showtime with gh signed in, or showtime render project for these exact frames.
