On Pinterest, other clips, when posted with the video as-is, generate a TAB draft

When watching a short guitar fingerstyle clip on Pinterest lasting roughly 15 to 30 seconds, it is natural to wonder, "What chord progression is this?" However, because the clip is brief, searching for the song title rarely yields accurate sheet music. In such situations, the most efficient approach is to feed the video file itself into an AI transcription tool, bypassing any separate audio extraction process. AnthemScore Web supports MP4 as an input format, so conversion begins simply by dragging and dropping a Pinterest video saved on your smartphone into the browser. Additionally, since the free trial allowance is the "first 30 seconds of a song," this is usually sufficient to generate a TAB draft (where fret positions are marked with numbers) for most short Pinterest clips without payment. Please note in advance that the converted result is not a finalized score but an "editable draft," and sections where multiple notes ring simultaneously must be verified and corrected manually.

A Converter That Accepts MP4 Files Directly

Many standard audio-to-score conversion tools support only sound files such as MP3 or WAV, making an intermediate step to extract audio from video essential. AnthemScore Web allows you to omit this step. According to its official page, the list of acceptable input formats includes MP3, WAV, M4A, FLAC, OGG, MP4, and MID, enabling immediate upload by drag-and-drop or file selection via explorer ¹. This means Pinterest clips saved on a smartphone can be inserted directly into the converter.

During conversion, musical information is displayed in real-time instead of a simple progress bar. The demonstration screen reveals key details during the audio analysis phase, including ♩ = 92 BPM, 4/4 time signature, C major, and a C · Em · G · D chord progression ¹. Before the conversion completes, you can grasp the overall framework: "This clip is in C major, 4/4 time." Furthermore, result options for 'chord notation' and 'TAB' are provided ¹. For guitarists, TAB is often more intuitive than notes on a staff because it indicates where to place fingers, so the output is prepared in a format suitable for practice workflows.

The Fit Between the Free 30-Second Limit and Short Clips

The tool’s free trial conditions align well with the characteristics of Pinterest clips. The free trial for AnthemScore 6 Desktop version permits transcription of up to the first 30 seconds per song and 100 times in total ². To convert entire songs, one must purchase Lite ($29), Professional ($39), or Studio ($99) ². The web version also offers a free trial via browser and mobile, while full-song conversion requires a subscription ². Since Pinterest guitar short clips typically fall within 30 seconds, if the goal is "I only want to know about this specific section, not the whole song," it is possible to obtain a draft without payment.

However, it is important to distinguish that the 30-second limit does not guarantee the quality of the conversion. Even in short clips, if chords and bass lines overlap, the accuracy of the draft may decrease. Therefore, whether the service is free or paid and the accuracy of the output are separate issues; results from the free trial should be viewed strictly as a "starting point."

How Notes Are Read from Sound and Prerequisites

The core of the converter is artificial intelligence analyzing sound to locate notes. AnthemScore analyzes audio based on a convolutional neural network (CNN), a deep learning technique that finds patterns in frequency profiles similar to image recognition ³. The focus is on reading the onset points, durations, and velocities of the waveform together to produce a better draft than simple pitch detection ³.

The 7-Step Process Observed in the Actual Interface

A specific case illustrating the before-and-after editing process is a tutorial released by YouTuber 樂團城市Citii in January 2024 ⁴. The procedure shown in this video is as follows:

In step 6, the author of this tutorial explicitly warns that "automatic transcription may not be 100% accurate for complex or polyphonic (multiple notes ringing simultaneously) music" ⁴. AnthemScore accepts this limitation through its "editable draft" structure, providing editing tools to add or delete notes via sliders and insert or remove measures, along with a playback feature that slows down tempo without changing pitch ², ⁵.

Refining the Draft into Final TAB

The draft created by the converter may omit "which technique to use to produce a note." Tools like Tabtify serve a complementary role here. Tabtify allows the addition of performance symbols such as bending (b), slide (/), and hammering (h), and enables playback via the spacebar to check awkward sections ⁶. While Tabtify also creates AI TAB drafts from YouTube links or recordings, this is a feature exclusive to the Pro Plan ⁶. Free accounts can write, play, and export (GP, MIDI, PDF, MusicXML), but the library is limited to three tabs ⁶.

Practically, one can combine two paths. After extracting a draft using AnthemScore’s 30-second free trial, the work of correcting performance symbols and exporting as PDF, MIDI, or MusicXML can be completed in an editor like Tabtify. Although AnthemScore itself supports selecting TAB format and exporting to major file formats ², a dedicated editor like Tabtify may be faster for intuitively adding specific symbols or sharing PDF parts with other members.

So, Are Free Tools Sufficient for Short Clips?

Guitar clips saved from Pinterest, lasting around 30 seconds, can be uploaded to AnthemScore Web as MP4s directly to obtain a TAB draft within the free allowance ¹, ². This is because MP4 is an accepted input format, eliminating the audio extraction step, and the 30-second free trial limit overlaps with the length of short clips.

This draft is a starting point, not a conclusion. Clips tuned differently from A440 require pre-tuning ³, and sections with multiple notes ringing simultaneously may be inaccurate, requiring note correction and timing adjustment ⁴. For the purpose of "let’s try practicing by roughly figuring out the fret positions and chords of this 20-second loop," rather than "transcribing the entire song," a 30-second free conversion followed by manual refinement is a realistic method worth trying now.
