🎥 Video Captions — SRT files

Illustrative SRT drafts for the four script concepts. They have not been synced to final footage and are not ready to upload.

:::warning Validation state Regenerate timestamps from the locked edit and proofread the resulting SRT. Video 3 has been rewritten around the current recommendation/detail/timer flow, but its timing is still illustrative. Video 4 is blocked because public session sharing does not exist. The older blocked cue text is retained as concept copy only and must not be published as a product claim. :::

SRT spec reminder:

  • Sequential integers for cue numbers
  • Timestamps: HH:MM:SS,mmm --> HH:MM:SS,mmm
  • 2 lines per cue max, ~42 chars per line
  • Blank line between cues

1
00:00:00,000 --> 00:00:05,000
The difference between a video AceSense can analyse
and one it can't comes down to three things.

2
00:00:05,000 --> 00:00:08,000
I'll show you all three in the next two minutes.

3
00:00:08,000 --> 00:00:15,000
One — film from behind the baseline,
as high as you can get.

4
00:00:15,000 --> 00:00:22,000
A fence clamp works. A tripod works.
Even a friend standing still works.

5
00:00:22,000 --> 00:00:30,000
You want the full court in frame,
including where the ball lands.

6
00:00:30,000 --> 00:00:35,000
✅ Full court visible · ✅ Camera steady · ✅ Height > 6 ft

7
00:00:35,000 --> 00:00:42,000
Two — record in daylight if you can.
Indoor courts work too.

8
00:00:42,000 --> 00:00:50,000
If you can see the ball clearly on your phone screen,
the AI can track it.

9
00:00:55,000 --> 00:01:02,000
Three — check the recording limit shown for your plan.
A rally, a set, a full practice — anything in that window.

10
00:01:02,000 --> 00:01:10,000
The app uploads one file, so stay within your plan's limit.
If it's shorter, you won't get enough data.

11
00:01:10,000 --> 00:01:18,000
Open AceSense. Tap the big green Start New Session button.

12
00:01:18,000 --> 00:01:25,000
You get two options — upload an existing video,
or record one right now. We'll upload.

13
00:01:25,000 --> 00:01:32,000
The app shows you the file size, estimated upload time,
and a tips card. Tap Upload.

14
00:01:32,000 --> 00:01:42,000
Upload takes 30 seconds on wifi
to a few minutes on cellular.

15
00:01:42,000 --> 00:01:55,000
You can close the app — we'll push a notification
when analysis is done.

16
00:01:55,000 --> 00:02:05,000
While you're waiting, your video is on a GPU server
running computer vision.

17
00:02:05,000 --> 00:02:15,000
Ball tracking, court detection, pose estimation.
Processing time varies with the recording and service load.

18
00:02:15,000 --> 00:02:22,000
That's it. Camera steady, good light,
Stay within your plan's limit, then upload.

19
00:02:22,000 --> 00:02:30,000
Do this once today — even a 5-minute rally
against a wall. 🎾

📄 video-2-read-analysis.srt​

1
00:00:00,000 --> 00:00:06,000
You just got your first AceSense analysis
and there's a lot on this screen.

2
00:00:06,000 --> 00:00:10,000
I'll walk you through every tab in three minutes.

3
00:00:10,000 --> 00:00:18,000
Default view is Overview. Four numbers at the top —
total shots, accuracy, max speed, session count.

4
00:00:18,000 --> 00:00:26,000
Most people obsess over max speed,
but for improvement, look at accuracy.

5
00:00:26,000 --> 00:00:32,000
That's the percentage of your shots
that landed in-court.

6
00:00:32,000 --> 00:00:42,000
The donut chart shows what shots you hit.
Forehands, backhands, serves, volleys.

7
00:00:42,000 --> 00:00:50,000
This is where most players get surprised —
you probably hit way more backhands than you thought.

8
00:00:50,000 --> 00:01:00,000
At the bottom — AI Coach Insights.
Read it. Single most actionable thing on the screen.

9
00:01:00,000 --> 00:01:10,000
Second tab — Shots. Every shot you hit, one by one.

10
00:01:10,000 --> 00:01:20,000
Tap any shot to see biomechanics —
elbow angle, wrist velocity, ball speed.

11
00:01:20,000 --> 00:01:30,000
The pose animation shows you
what your body actually did.

12
00:01:30,000 --> 00:01:45,000
The tip card says something like:
"Extend your arm 15 degrees more for +12% power."

13
00:01:45,000 --> 00:01:55,000
Third tab — Heatmap. The court is divided into 8 zones.
Colour shows where your shots landed.

14
00:01:55,000 --> 00:02:05,000
Bright green equals a lot of shots. Dark equals few.

15
00:02:05,000 --> 00:02:15,000
Use the filter to see just forehands, just serves.

16
00:02:15,000 --> 00:02:30,000
If your forehand heatmap only lights up one zone,
you're predictable. Coaches love this tab.

17
00:02:30,000 --> 00:02:42,000
Fourth tab — Stats. Averages, rally length,
training recommendations.

18
00:02:42,000 --> 00:02:50,000
On Pro, this compares you to your past sessions
so you can see actual improvement.

19
00:02:50,000 --> 00:03:00,000
Next video — turn the AI's recommendations
into a practice drill that fixes your weak spots.

📄 video-3-use-drills.srt​

1
00:00:00,000 --> 00:00:06,000
Your analysis includes a practical next step.

2
00:00:06,000 --> 00:00:10,000
Here's how to open the recommended drill
and run its timer.

3
00:00:10,000 --> 00:00:22,000
AceSense chooses from the strokes
classified in this session.

4
00:00:22,000 --> 00:00:35,000
When there is enough evidence, tap Open Drill.
Otherwise, browse the full practice list.

5
00:00:35,000 --> 00:00:48,000
Check the focus, difficulty,
description, and duration first.

6
00:00:48,000 --> 00:01:00,000
Then read the step-by-step instructions
and pro tips.

7
00:01:00,000 --> 00:01:15,000
Review the expected feel, equipment,
and common mistakes before you begin.

8
00:01:15,000 --> 00:01:25,000
Use Start and Pause while you work.

9
00:01:25,000 --> 00:01:35,000
Reset returns to the configured duration.
The timer does not save practice history yet.

10
00:01:35,000 --> 00:01:45,000
Open the recommendation, read the drill,
and use the timer.

📄 video-4-share-with-coach.srt​

Blocked: do not use this track until public session sharing ships and the script is re-recorded against the released flow.

1
00:00:00,000 --> 00:00:06,000
You just played. You've got 20 minutes until your lesson.

2
00:00:06,000 --> 00:00:12,000
Here's how you get your coach up to speed
before you even walk into the club.

3
00:00:12,000 --> 00:00:20,000
Open the session. Top right — Share button. Tap it.

4
00:00:20,000 --> 00:00:30,000
Two options. Copy Link — the fastest.
Paste into iMessage, WhatsApp, email.

5
00:00:30,000 --> 00:00:42,000
Or Download Report — generates a PDF
with the whole analysis baked in.

6
00:00:42,000 --> 00:00:50,000
Your coach taps the link.
They don't need the app.

7
00:00:50,000 --> 00:01:00,000
They see your full analysis in the browser —
same heatmap, same stats, same insights.

8
00:01:00,000 --> 00:01:10,000
They can read it on the way to the court.

9
00:01:10,000 --> 00:01:22,000
On the free tier, anyone with the link can view.
On Pro, sharing is private-by-default.

10
00:01:22,000 --> 00:01:35,000
This changes lesson prep.
Instead of "how did it feel" — no one can answer that.

11
00:01:35,000 --> 00:01:48,000
Your coach walks in already knowing
you hit 60% of backhands into net on the ad side.

12
00:01:48,000 --> 00:01:55,000
They coach the actual problem.

13
00:01:55,000 --> 00:02:00,000
Upload, analyse, share. Three taps.
That's the full loop.

14
00:02:00,000 --> 00:02:08,000
If your coach isn't already on AceSense,
send them this video. 🎾

🌍 Localization​

SRT files are language-agnostic in timing — only the text changes. For non-English releases:

  1. Run each SRT through professional translation (not raw machine translation — tennis jargon matters).
  2. Save as video-N-<lang>.srt (e.g. video-1-es.srt, video-1-pt.srt).
  3. YouTube supports uploading multiple caption tracks per video.
  4. Pre-priority languages by tennis market size:
    • Spanish (Spain, Argentina, Mexico) — large recreational base
    • Portuguese (Brazil) — tennis growing
    • French — strong coaching market
    • Japanese — large consumer base
    • German — strong club scene

♿ Accessibility notes​

  • Line length ≤ 42 chars for optimal reading at 200 WPM.
  • Keep captions within the safe area — TikTok/Reels UI covers top 8% / bottom 20%.
  • No "[Music]" or "[Background noise]" tags unless they're significant — they clutter the experience.
  • For Reels/TikTok burned-in captions, use a heavier font weight (Inter Black) with dark stroke outline so the text survives bright pixel backgrounds.
  • Spanish / German caption files can break the 2-line/42-char rule naturally — allow 3 lines where needed rather than truncate meaning.
