A MOD needs audio rendering and a visual decision before FLV exists
A ProTracker-style MOD is tracker music, not video. It contains sample data plus patterns, order positions, rows, notes, speed, tempo, loops, and effects. An FLV file needs audio and/or video tags. A MOD-to-FLV job therefore has two deliberate stages: render the tracker composition with a stated player policy, then create a video track such as an illustrated title, pattern display, scope, waveform, or animation. Do not imply that a source MOD contains native images or video frames.
Keep the MOD source. It is the editable composition. The FLV is a delivery rendering with a selected audio interpretation and an invented or derived visual rule. A filename, sample label, or tracker title is not evidence of an author, performer, or license, so publish only verified attribution.
Choose FLV only for a legacy Flash-related target that actually asks for it. Modern receivers frequently have different support expectations, so test the destination before a long visual render.
Render MOD orders patterns samples and effects as the audio reference
A common MOD layout has sample headers, an order list, patterns, and sample bytes. The order list tells the engine which patterns to play. Pattern cells can include period, sample number, effect code, and parameter. Effects such as pitch slide, vibrato, volume change, sample offset, pattern break, jump, speed, tempo, and loops are musical instructions. Sample bytes alone are not the song.
Choose a tracker engine and compatibility policy before video work begins. Different players can differ around unusual effects, panning, finetune, loops, and end detection. Record the player/version, module identity, stereo or mono policy, output rate, and loop/end rule. Compare pattern transitions and effect-heavy passages before declaring the audio reference final.
A looping module needs a defined delivery duration. Render one intentional play-through, a named number of repeats, or a chosen excerpt. An FLV cannot preserve the editable tracker loop logic.
Use a visual rule that is honest about the tracker source
A transparent visual derivative can show a static title card, an order/pattern display from the named renderer, channel activity, a waveform, a spectrum, or original pixel art. State which it is. A scope is derived from rendered audio; a pattern display is derived from the selected player interpretation; a decorative animation is not evidence of the original composition.
Map visual changes to the rendered audio reference, not guessed file size or a presumed fixed tempo. Tracker speed and tempo can change inside a song. Use event timestamps or audio timing for pattern changes and record the excerpt start and end. Avoid fast flashing, retain legible labels, and do not rely on color alone to identify channels.
| Source fact | MOD | FLV visual decision |
|---|---|---|
| Audio | Player renders samples and effects | Encoded render becomes audio tag payload |
| Video | No native video frames | Create stated title, tracker view, or visualizer |
| Timing | Orders, rows, speed, tempo, effects | Map frames to the chosen reference timeline |
| Metadata | Limited module labels | Use only verified title/credit facts |
| Preservation | Editable patterns and samples | Flattened audiovisual derivative |
| Validation | Tracker-aware reference playback | Check audio and visual sync at key events |
Recognise the FLV header tags and timestamps in the delivery file
An FLV begins with the signature FLV, a version, type flags indicating audio and video tag presence, and a data offset that is commonly 9 for version 1. The file then carries tags. The specification distinguishes audio, video, and script-data tag types; tags contain header information, timestamp data, and payload. The header only says that tags are present, not that a receiving player supports the codecs inside them.
A tracker-to-FLV visual is therefore a newly timed file. Audio and video timestamps should be checked against the chosen reference at the start, a pattern change, any tempo shift, and the selected ending. A valid header cannot compensate for a visualizer that drifts from the audio after accumulated timing rounding.
Choose video detail and audio rate from the legacy target
Set dimensions, frame cadence, visual complexity, audio settings, and duration from the receiver. Pattern grids and pixel art usually benefit from readable, stable graphics; full-screen noise, gradients, and unnecessary movement cost data without improving a tracker explanation. A higher output rate cannot add detail absent from classic MOD samples or repair a wrong source rendering.
Keep audio and visual choices separate. The audio should preserve the approved tracker render as well as the target allows; the video should be simple enough to remain legible. Test a hard segment with effect changes and a dense visual frame, not only a static title screen.
Validate FLV playback and the claimed relation to the MOD
Open the final FLV in the actual legacy application or route. Check it starts, has sound, shows the intended visual, keeps sync at anchor events, seeks as expected, and ends at the stated point. A modern player that accepts it is not proof that the target Flash-era workflow does.
If timing is wrong, determine whether the tracker reference, visual timestamp mapping, or receiver scheduling is responsible. If audio is wrong, revisit the MOD renderer before changing FLV settings. If the file is too large, reduce duration, dimensions, frame frequency, or visual complexity deliberately rather than silently removing musical events.
MOD-to-FLV questions before a legacy visual export
Can I rename MOD to FLV?
No. A MOD needs tracker playback, while FLV needs a tagged audiovisual file with encoded payloads and timestamps.
Does the MOD contain the video?
No. Choose and label the visual rule honestly.
Why does the animation drift?
Tempo/effect changes and timestamp rounding need a reference-based mapping, not an assumed constant frame rate.
Will FLV preserve editable patterns?
No. Keep the MOD for samples, orders, patterns, effects, and future renders.
Why test the exact player?
FLV and codec support vary, especially in older workflows.
Use MOD row events as evidence, not decoration. A visible tracker grid can be useful when it shows the exact pattern/order position from the renderer chosen for the audio reference. It should not silently invent notes, instruments, or an author story. If an effect command changes tempo or jumps order position, mark the visual transition from the rendered event time and check it against audible playback. This is more informative than animating a generic equalizer with unrelated movement.
FLV tag timestamps need an end-to-end check. The audio and video tag timelines are created after MOD playback. Test zero time, a first pattern boundary, an effect-driven tempo change, and the last intended frame. If the visual ends before the audio, decide whether the final state should hold or whether the audio should be cut at a documented endpoint. Do not hide this decision by claiming the module itself provided a video duration.
Keep visual delivery separate from rights claims. A module title may be truncated and a sample name can be a technical label, not creator attribution. Publish a companion note only with source facts you have verified: input identity, renderer, excerpt bounds, visual source, and any known credit or license. The FLV is a presentation asset, not a proof of ownership or source authenticity.
Plan visual compression around meaning. A restrained palette, stable background, and changed regions where an event actually changes improve readability and file size. Repeated full-screen noise or arbitrary flashing makes a legacy delivery file larger and less accessible. Reduce duration or visual complexity deliberately; do not remove a musically important pattern transition without disclosing the shorter excerpt.
Choose the audio reference before animation timing. A MOD effect may alter the playback rate after a row begins, and pattern flow can skip or repeat parts of the score. Render audio first, inspect the duration and anchor events, then build FLV frame timestamps from that reference. Starting an animation from a guessed number of patterns or a fixed assumed beats-per-minute value produces a visual that may appear aligned at the start but diverge at the next tempo or jump command.
Document a silent visual if you do not include audio. FLV supports audio and video tags, but an illustrated MOD excerpt can be intentionally silent. In that case say so, supply a separate approved audio render when listening matters, and avoid labels such as “music video” that imply a soundtrack. The MOD itself remains the source for tracker playback and examination.
Check codec support independently from file structure. A player can recognise the FLV signature and still reject the audio or video payload. Test the exact player or historical workflow that requires FLV, including an early seek and the last few seconds. A valid header, tag order, or timestamp field is necessary, but it is not a substitute for receiver codec compatibility.
