When should I use a script of your own instead?

You have one video source, one fixed question, files already on disk, and no need for anything to change.

Playhead vs your own yt-dlp and ffmpeg script

You can absolutely do this yourself: yt-dlp fetches the video, ffmpeg extracts frames at whatever rate you pick, and a transcription call gets you the words. That part is an afternoon. What takes the other months is everything after it: keeping every claim tied to the second it belongs to, knowing what you did and did not cover, telling a dissolve from a cut, and keeping nine platforms working when they change their minds about who may download what.

What a script of your own is better at

First, because a comparison that opens with our own advantages is an advertisement rather than a comparison.

Free, entirely under your control, and no vendor to depend on.
You can tune it to exactly one use case, which a general tool never fits perfectly.
No data leaves your infrastructure.
For a single fixed pipeline over your own files, this is often the right call.

What it is, and where it runs

What it is, and where it runs: Playhead compared to a script of your own
Capability	Playhead	a script of your own
Nothing to install or maintain	YesOne URL. The toolchain is ours to keep working.	Noyt-dlp needs updating roughly weekly, and each platform breaks in its own way.
Platform access when a site starts refusing datacenter traffic	YesTLS fingerprinting per platform, proof-of-origin tokens for YouTube, and a retry path when one route is blocked.	NoThis is the part that turns a weekend project into an ongoing job.

What it can look at

Capability	Playhead	a script of your own
Every claim carries the second it is about	YesThe times come from the video itself rather than from what a model remembers, so a moment cannot drift from the second it belongs to. You can open the video at that second and check it.	PartlyPossible, and it is exactly this list that is the work.
States what it covered and where the gaps are	YesEvery response carries a coverage object: covered seconds, whether that was the whole video, every second it was not, and where to resume.	PartlyPossible, and it is exactly this list that is the work.
SMPTE timecode from camera and edit-suite masters	YesWhen a file carries SMPTE timecode you can ask for it, which is the clock an editor's notes and the edit suite are already in. Elapsed seconds are the default, and both are true.	PartlyPossible, and it is exactly this list that is the work.
Broadcast and production containers	YesMXF (XAVC, XDCAM, AVC-Intra, DNxHD), ProRes MOV, GXF, LXF, TS and DV. Camera raw is refused by name with the export to make instead, rather than failing obscurely.	PartlyPossible, and it is exactly this list that is the work.
Photo carousels (TikTok photo mode, Instagram)	YesA carousel has no clock, so each slide is one second: second 0 is slide 1, second 1 is slide 2. The answer says so rather than implying the post has a running time.	PartlyPossible, and it is exactly this list that is the work.
Meta Ad Library links	YesA facebook.com/ads/library link is a video like any other, which is what makes competitor-ad teardowns a normal call rather than a workaround.	PartlyPossible, and it is exactly this list that is the work.

How closely it can look

Capability	Playhead	a script of your own
Ask about one corner of one moment	Yeswindow says when and region says where, so a follow-up about the badge in the top right is read at the size it needs. That is what makes 12 pt legal type, a price and a logo lock-up readable at all. It costs the seconds you name, not the video.	PartlyPossible, and it is exactly this list that is the work.
Two consecutive frames, 33 ms apart	YesA question about a single second is answered at the distance where an easing curve, a dropped frame or a one-frame logo flash is visible at all.	PartlyPossible, and it is exactly this list that is the work.
Vertical video is read as vertical video	YesA 9:16 recording is read at its own shape, so you never pay for empty space beside a tall picture. Black bars are found first, so a 16:9 clip reposted into a vertical frame is read as the 16:9 clip it is.	PartlyPossible, and it is exactly this list that is the work.
Decide what a video is worth before you pay to read it	Yesdepth: glance reads fewer moments for about a sixth of the price, dates every second the same way, and names the stretches it did not cover. A folder of forty recordings can be sorted before one of them is read properly.	PartlyPossible, and it is exactly this list that is the work.

What it measures

What it measures: Playhead compared to a script of your own
Capability	Playhead	a script of your own
Cut times returned as numbers	YesCut times come back as a list of seconds, with the pacing beside them: how many shots, the median shot length, and cuts per minute.	PartlyPossible, and it is exactly this list that is the work.
Transitions classified, not counted as cuts	YesDissolves, fades, dips, wipes and whip-blurs are detected on a longer baseline and named. Without that, a film with six dissolves reads as six extra cuts and its pacing comes back too fast.	PartlyPossible, and it is exactly this list that is the work.
Freezes, black frames and silence detected	YesFreezes, black frames, silence and loudness all come back together, which is what a render check is made of.	PartlyPossible, and it is exactly this list that is the work.
Sees what happened between the sampled frames	YesEvery frame of the video is measured, not a sample of them, so a one-frame flash, a three-frame cut and a slow push-in are all found and dated.	PartlyPossible, and it is exactly this list that is the work.
Says whether the audio was speech at all	YesMusic scored over a video transcribes into fluent sentences nobody said. The response reports that assessment instead of handing back lyrics as dialogue.	PartlyPossible, and it is exactly this list that is the work.
Watermarks and channel bugs located, with the cuts they survived	YesA logo, a watermark or a badge laid over the picture comes back with where it sits, in words and as a box, and how long it stays. Whether it is there is measured; what it says is read when you ask.	PartlyPossible, and it is exactly this list that is the work.
Camera moves measured, with a direction and a distance	YesPush-ins, pull-outs and pans come back as spans carrying the scale change in percent, how far the frame travelled as a fraction of its width, the direction, and a fit score that says when the picture moved for some other reason. A half-percent-per-second push-in is not visible between two sampled frames and is reported anyway.	PartlyPossible, and it is exactly this list that is the work.
Overlays and one-frame flashes, with where on screen they sat	YesA caption, a lower third, a progress bar or an animated watermark comes back with a start, an end, where it sits and how much of the picture it covers. A flash that lasts one frame is reported the same way.	PartlyPossible, and it is exactly this list that is the work.

Building on it

Capability	Playhead	a script of your own
Tunable to exactly one pipeline	PartlyYou choose the seconds, the part of the picture, how much of the video to read, and the shape of the answer. Wide, and still somebody else's set of choices.	YesYou control every parameter, and a general tool never fits one fixed use case as precisely as code written for it.
Token arithmetic done for you	YesEvery answer says what it charged, and a first look is quoted by the length of the video before you call.	NoThe most common and most expensive mistake here: extracting frames larger than any model will actually look at.

Running it

Running it: Playhead compared to a script of your own
Capability	Playhead	a script of your own
Free, with no per-video cost	Partly50,000 credits a month free, then paid. A follow-up about a video you already asked about costs a fraction of the first question.	YesYour own hardware and your own Whisper key. At high volume on footage you already hold, this is simply cheaper.
Video never leaves your infrastructure	NoThe hosted service downloads and processes on our machines. An on-premise deployment exists for enterprise; the hosted product does not run locally.	YesNothing leaves. For footage under NDA, or anything a data-processing agreement covers, this decides it on its own.
No vendor to depend on	NoIf we are down, you are down. That is the trade for not maintaining a toolchain.	YesIt breaks when you break it, and you can fix it the same afternoon.

The verdict

Which is to say: what actually decides it, rather than which row count is higher.

The part people underestimate is not the extraction, it is knowing what you did not see. A script that quietly samples 100 frames from a 40 minute video produces confident answers about the 39 minutes it never looked at, and nothing in the answer says so. Playhead is the version of that script that states its gaps: what the video does not show is named, and what the reading could not settle comes back with the exact call to settle it.

If none of that applies, and you want it on a phone, in a scheduled job or shared with a team, the quickstart is two minutes and the free tier needs no card.
