| # time-lapse-artifacts |
|
|
| 532 time-lapse recordings of one artist's traditional drawing practice across |
| nearly two years (September 2024–August 29, 2026), with standardized acquisition |
| since July 13, 2025. Across approximately 2.03 TB of video, the archive follows |
| the same artist working in physical media—including pencil, ballpoint pen, |
| fountain pen, brush, graphite, and ink—on fixed-format paper and illustration board. |
| The release combines 404 canonical Standard videos and 128 earlier |
| Pre-Standard recordings. Every published video has a persistent record ID, |
| content hash, byte size, and encoded-stream metadata; historical session and |
| provenance fields remain less complete in the Pre-Standard tier. |
|
|
| **Unit of record:** each active metadata row identifies one published MP4 |
| video object. A row does not necessarily represent one drawing, one |
| uninterrupted session, or a complete start-to-finish process. When documented, |
| fragment-sequence and physical-reference relationships remain in separate |
| revision-pinned sidecars joined by `record_id`; absent relationships remain |
| unknown. |
|
|
| **[Browse the Standard recordings](https://maxwellinked.github.io/time-lapse-artifacts/)** |
| through a searchable public browser with muted motion previews. The browser is |
| a dynamic presentation layer and may lag the current Hugging Face dataset. |
| Hugging Face remains authoritative for media, record identities, and |
| machine-readable metadata. |
|
|
| In this dataset, provenance refers to the documented relationship between a |
| physical drawing and its time-lapse record, rather than to histories of |
| ownership or sale. |
|
|
| An earlier 2012–2016 archive of more than 8 TB also exists, consisting |
| primarily of uploaded 1080p drawing videos, with some livestream-derived |
| material. It is not yet published in this dataset and is excluded from the |
| current 532-record, 2.03-TB release totals. This is an active construction |
| release. |
|
|
| ## Snapshot and Coverage |
|
|
| The table below describes this revision. Batch-level history is maintained in |
| [`CHANGELOG.md`](CHANGELOG.md). The immutable `v0.3.0` tag remains a 467-row |
| historical release and does not describe current `main`. |
|
|
| | Collection tier | Published MP4s | Indexed rows | Date coverage | Metadata state | |
| | --- | ---: | ---: | --- | --- | |
| | `standard` | 404 direct files | 404 | 2025-07-13–2026-08-29 | Complete core technical metadata for every direct Standard file | |
| | `pre_standard` | 128 | 128 | 2024-09-17–2025-07-09, plus 9 unknown dates | Complete core technical metadata; historical descriptive and provenance gaps remain | |
| | Earlier archive (unpublished) | 0 public videos | 0 | Historical scope 2012–2016 | More than 8 TB held outside this release; ingestion pending | |
|
|
| The Hub configurations use the split name `archive`. No official |
| train/validation/test partition has been defined. |
|
|
| ## Viewer and Metadata Discovery |
|
|
| The release exposes two explicit configurations so metadata-complete canonical |
| records are not silently mixed with historically less complete records: |
|
|
| - `canonical/archive` is the default and loads root `metadata.csv` with the 404 |
| direct files in `Standard_Time_Lapses/` |
| - `pre_standard/archive` loads `Pre_Standard_Time_Lapses/metadata.csv` with the |
| 128 direct files in that folder |
|
|
| Each configuration has the same declared 29-column schema. Stored dimensions |
| and byte sizes are nullable integers, `has_audio` is a nullable boolean, and |
| encoded frame rate remains a float because historical encodings include |
| fractional reported rates. Undocumented values load as null rather than as |
| zero or false. Both indexes declare tier membership directly: the root index sets |
| `collection_tier = standard` and `is_canonical = true`; the Pre-Standard CSV |
| sets `collection_tier = pre_standard` and `is_canonical = false`. |
|
|
| Published-index completeness is defined by the 404 rows in `canonical/archive` |
| plus the 128 rows in `pre_standard/archive` and their generated Parquet |
| exports. Hugging Face's separate column Statistics job is an auxiliary, |
| asynchronous surface; its availability is not used to claim or reject |
| row-level completeness. |
|
|
| The configuration lists the two active `metadata.csv` files and only direct |
| MP4 paths in `Standard_Time_Lapses/` and `Pre_Standard_Time_Lapses/`. It does |
| not use a recursive canonical glob, so the nested |
| `Standard_Time_Lapses/Provenance/` subtree is excluded. |
|
|
| ## Overview |
|
|
| `time-lapse-artifacts` documents analog drawing processes across different |
| recording periods and acquisition conditions. Raw video is the primary record. |
| Metadata identifies, organizes, compares, and documents recordings without |
| imposing aesthetic scores or stylistic labels. |
|
|
| The collection is a single-creator longitudinal archive. This makes it useful |
| for studying within-practice change, but it does not represent artists, |
| materials, studios, or drawing practices broadly. |
|
|
| ## Repository Structure |
|
|
| ### `Standard_Time_Lapses/` |
|
|
| The directory contains 404 direct MP4 files. `metadata.csv` is their complete |
| machine-readable canonical index: every direct file has one validated row with |
| core technical metadata. Direct placement alone is not sufficient for future |
| additions; metadata and release validation are required. |
|
|
| Each canonical metadata row now includes: |
|
|
| - a persistent `record_id` |
| - `collection_tier = standard` |
| - `is_canonical = true` |
| - `acquisition_protocol_version = standard-2025-07-13` |
| - descriptive session fields |
| - encoded video properties |
| - repository content hash and size |
| - provenance fields where documented |
|
|
| Files use a structured filename convention described in `SCHEMA.md`. A |
| filename is descriptive, but it is not the stable identity of a record; |
| external references should use `record_id`. |
|
|
| ### `Standard_Time_Lapses/Provenance/` |
|
|
| This subtree contains supporting historical records and retained exceptions. |
| It is not part of the canonical record set. |
|
|
| `2026-07-31/` preserves the completed provenance release, including mappings |
| between historical `Series_9x12` filenames and canonical records. The former |
| full duplicate video snapshot is not retained. Relationships are preserved |
| through mappings, hashes, metadata, and repository history. See the |
| [provenance navigation index](Standard_Time_Lapses/Provenance/README.md). |
|
|
| ### `Pre_Standard_Time_Lapses/` |
| |
| These 128 recordings predate the standard acquisition protocol. They are |
| published for archival continuity but are not interchangeable with canonical |
| standard records. Each now has a stable `record_id`, exact Hub content hash and |
| size, playback duration, stored dimensions and orientation, frame rate, codec, |
| pixel format, container, and audio-stream presence. Historical dates, times, |
| materials, and provenance remain incomplete where evidence is unavailable. |
| Missing values must not be interpreted as zero, false, or evidence that a |
| property was absent. |
|
|
| The folder-local `metadata.csv` is the active index for these 128 videos and is |
| loaded by the `pre_standard/archive` configuration. It follows the same |
| declared 29-field schema as the canonical index while leaving undocumented |
| historical fields empty. |
|
|
| Material that does not meet the archive's ownership and provenance threshold |
| is excluded from both the published media and the active metadata index. |
|
|
| ### `Earlier_Archive_2012_2016/` |
| |
| More than 8 TB of earlier material is held outside this dataset. It consists |
| primarily of uploaded 1080p drawing videos, with some livestream-derived |
| material. At the audited snapshot it contains no public video data. References |
| to 2012–2016 therefore describe archive scope, not current downloadable |
| coverage. |
| |
| ## Metadata and Provenance |
| |
| The metadata distinguishes documented facts, established historical |
| relationships, and unresolved information. Evidence may include: |
| |
| - exact file/blob identity |
| - original filenames and repository paths |
| - file sizes and hashes |
| - duration comparison |
| - visual continuity across recordings |
| - documented physical references |
| - repository commit history |
| |
| Uncertain relationships are not promoted to verified relationships solely |
| because dates or filenames look similar. |
| |
| The active CSV files and live Viewer use semicolons for multiple `tool` and |
| `medium` values, for example `Pencil;FountainPen` and `Graphite;Ink`. A pipe |
| (`|`) is **not** a valid separator in v0.2. The two fields are independent |
| observed-value lists; equal list lengths and positional pairing are not |
| guaranteed. See `SCHEMA.md`. |
| |
| `encoded_frame_rate` is encoded playback rate. It is not the original temporal |
| sampling rate of the drawing process. |
| |
| ### Physical-reference relationship layer |
| |
| [`Physical_References/endpoint_references.csv`](Physical_References/endpoint_references.csv) |
| links 309 Standard video records to owner-confirmed photographs of their |
| physical drawings through persistent `record_id` values and the pinned source |
| revision. It is a separate derived relationship table and does not alter the |
| 29-field canonical video index. |
|
|
| Version 0.1 records 52 confirmed endpoint photographs, one longitudinal |
| continuation, 232 owner-confirmed record references whose exact endpoint state |
| is not separately asserted, and 24 two-sided references. The photographs are |
| not bundled in this release. Their reviewed filenames and available hashes |
| preserve relationship evidence without implying that the media are publicly |
| downloadable. See the [sidecar schema](Physical_References/SCHEMA.md) and |
| [manifest](Physical_References/MANIFEST.json). |
|
|
| ## Acquisition and Stored-Video Orientation |
|
|
| The acquisition protocol effective July 13, 2025 is documented in |
| `Archive_Specifications.md`. Framelapse source fragments remain unchanged |
| acquisition evidence. A reviewed drawing may be represented canonically either |
| by one selected chronological assembly or by a complete, verified `RecNN` |
| sequence of unchanged source fragments. Grouping, order, completeness, and |
| noncanonical derivative coverage remain in a separate relationship manifest; |
| the active 29-field metadata schema is unchanged. A documented 4K/30-fps |
| InShot processing profile remains a candidate and does not retroactively |
| redefine existing records. See the |
| [capture and ingest protocol](Physical_References/CAPTURE_AND_INGEST_PROTOCOL.md). |
|
|
| The dated relationship sidecars preserve each ingestion as a separate pinned |
| observation layer. The |
| [`2026-08-27 sidecar`](Standard_Time_Lapses/Provenance/2026-08-27/fragment_sequence_relationships.csv) |
| has 27 rows: 22 canonical fragments across five complete sequences and five |
| noncanonical InShot derivatives. The |
| [`2026-08-29 sidecar`](Standard_Time_Lapses/Provenance/2026-08-29/fragment_sequence_relationships.csv) |
| has 19 canonical fragments across four complete sequences and no derivative |
| rows. In both, `fragment_set_label` is a descriptive grouping label, not a |
| global `work_id`. The nested derivative payloads are not included in the 532 |
| active rows or the active byte and duration totals. |
|
|
| The protocol's capture orientation and a file's stored pixel orientation are |
| different concepts. The `orientation`, `width_px`, and `height_px` metadata |
| describe the published encoded file. Historical canonicalization may include a |
| rotation, crop, or transcode; those transformations are documented only where |
| evidence currently exists and must not be inferred from dimensions alone. |
|
|
| The July 13, 2025 protocol boundary is explicitly encoded in canonical |
| metadata. It supports era-aware comparison of repeated physical-media practice, |
| but it is an acquisition change, not a skill-change label. Differences across |
| that boundary may reflect capture conditions as well as practice development. |
|
|
| ## Annotation State |
|
|
| Session-level descriptive and provenance metadata are curated by the creator |
| from the physical practice, filenames, file properties, and retained historical |
| evidence. This is the scope of `annotations_creators: expert-generated`; it does |
| not mean that frame-level task labels exist. |
|
|
| The videos themselves are primarily raw and unannotated. The release does not |
| provide: |
|
|
| - frame-level bounding boxes or segmentation masks |
| - hand, pen-tip, pose, or stroke labels |
| - aesthetic or quality scores |
| - imposed stylistic classifications |
| - calibrated physical trajectories |
| - original capture timestamps for individual time-lapse frames |
|
|
| Researchers may derive annotations, but derived labels should identify the |
| source `record_id` and pinned repository revision. |
|
|
| ## Intended and Unsupported Uses |
|
|
| ### Reasonable uses in the current release |
|
|
| - archival and drawing-process research |
| - qualitative within-creator analysis of practice and skill development across |
| repeated physical-media sessions |
| - self-supervised video representation experiments |
| - frame-change, scene, and workspace analysis |
| - development of annotation and tracking methods |
|
|
| ### Uses requiring additional validation or calibration |
|
|
| - hand or pen-tip tracking |
| - optical-flow comparison across acquisition eras |
| - temporal behavior analysis |
| - real-world trajectory, velocity, acceleration, or motor-control measurement |
|
|
| The release does not currently provide capture intervals, acceleration factors, |
| source-frame timestamps, camera calibration, or pixel-to-physical coordinate |
| mapping. Encoded time-lapse playback must not be treated as real drawing time. |
|
|
| ### Not validated |
|
|
| - population-level claims about artists or drawing behavior |
| - clinical, biometric, authorship, or identity inference |
| - a leakage-safe training or evaluation benchmark |
| - commercial use outside the CC BY-NC 4.0 terms |
|
|
| ## Limitations and Sources of Bias |
|
|
| - The archive documents one creator and one evolving practice. |
| - Current public video coverage begins in 2024, not 2012. |
| - The standard and pre-standard tiers have substantially different historical |
| descriptive/provenance completeness and acquisition conditions. |
| - The workspace can contain hands, tools, phones, tablets, reference material, |
| and other objects that may create visual shortcuts or occlusion. |
| - Stored resolution and frame rate do not establish physical or temporal |
| calibration. |
| - Large files make exhaustive inspection and replication expensive. |
| - No official leakage-safe split exists. |
|
|
| ## Rights, Privacy, and Audio |
|
|
| The creator confirms ownership of the published video files and depicted |
| creator-owned drawings. Material that cannot pass the ownership and provenance |
| review is not part of the active public index and is not distributed by this |
| release. This statement does not independently grant rights in incidental |
| third-party material that may appear on screens, in references, or in captured |
| audio. |
|
|
| Nearly all published masters retain an audio stream. `has_audio` records stream |
| presence only; it does not establish that the stream contains meaningful |
| signal. Users are responsible for reviewing audio, visible screens, references, |
| reflections, tattoos, and other potentially identifying or third-party content |
| before redistribution or model release. A future proxy release should remove |
| audio by default while preserving the archival masters. |
|
|
| ## Access and Reproducibility |
|
|
| The active 532-video release contains 2,030,832,764,048 bytes of video |
| (approximately 2.03 TB, or 1.85 TiB). Canonical files are often several |
| gigabytes each, so users should select records through `metadata.csv` before |
| downloading video. |
|
|
| ### Bandwidth-safe Quick Start |
|
|
| Install Hugging Face Datasets, stream the archive, and disable decoding while |
| selecting records: |
|
|
| ```python |
| from datasets import Video, load_dataset |
| |
| dataset = load_dataset( |
| "maxwellinked/time-lapse-artifacts", |
| "canonical", |
| split="archive", |
| streaming=True, |
| ) |
| metadata = dataset.cast_column("video", Video(decode=False)) |
| first = next(iter(metadata)) |
| print(first["video"]["path"], first["tool"], first["medium"]) |
| ``` |
|
|
| This exposes the complete metadata schema without transferring video bytes. |
| Default decoded row access additionally requires `torchcodec` and a compatible |
| video-decoding stack. Use `streaming=True` unless a full archive download is |
| intentional. |
|
|
| Use `"pre_standard"` as the configuration name to stream the earlier tier. |
|
|
| ### Download and Verify One Record |
|
|
| Install `huggingface_hub`, then use the included helper with a stable |
| `record_id`: |
|
|
| ```bash |
| python -m pip install huggingface_hub |
| ``` |
|
|
| The helper resolves the requested revision to an immutable commit, checks the |
| indexed byte size and Xet identity against the pinned Hub headers, and reports |
| the ordinary LFS-compatible SHA-256 separately. |
|
|
| Check a record without downloading its video: |
|
|
| ```bash |
| python tools/download_verified.py tla-a66bdad6c903b89f --check-only |
| ``` |
|
|
| Download that record and verify its local byte size and SHA-256: |
|
|
| ```bash |
| python tools/download_verified.py tla-a66bdad6c903b89f \ |
| --revision "<commit-or-tag>" \ |
| --output-dir downloads |
| ``` |
|
|
| `hub_xet_hash` is an Xet file ID, not the SHA-256 of the downloaded bytes. The |
| helper verifies both identities without conflating them. Video downloads may |
| be many gigabytes; use `--check-only` first. |
|
|
| For reproducible work: |
|
|
| 1. Pin a repository commit or release tag. |
| 2. Record the selected `record_id` values. |
| 3. Preserve the published `hub_xet_hash` values. |
| 4. State whether audio was retained. |
| 5. Document all rotation, crop, sampling, decoding, and proxy-generation steps. |
|
|
| Run the included validator before publishing a metadata change: |
|
|
| ```bash |
| python tools/validate_metadata.py metadata.csv \ |
| --pre-standard-metadata Pre_Standard_Time_Lapses/metadata.csv |
| ``` |
|
|
| `tools/enrich_prestandard.py` reproduces the Pre-Standard technical fields |
| from a pinned Hub inventory and MP4 container headers. It uses HTTP range |
| requests through FFmpeg; it does not intentionally download complete videos. |
| `tools/capture_hub_inventory.py` records the corresponding Xet file IDs from |
| resolve headers without following redirects or transferring video payloads. |
|
|
| The v0.2 index can be regenerated from the pinned 335-row source index plus the |
| three audited additions: |
|
|
| ```bash |
| python tools/repair_metadata.py source_metadata.csv metadata.csv \ |
| --additions tools/metadata_additions_v0.2.csv |
| ``` |
|
|

| The repository is under active construction. Record identity is carried by |
| `record_id`; a filename may be corrected without creating a new conceptual |
| record. Content replacement must retain provenance and should receive a new |
| content hash. |
|
|
| See `CHANGELOG.md` for release-level changes. |
