Nobody remembers which one was approved, whether it used a reference photo, or if the mobile crop was checked.\n\nThe problem is not the filename. The file has lost its history.\n\nA short YAML manifest can keep that history beside the asset.\n\n## Record What the Team Needs\n\nThe caf\u00e9 banner shows a coffee cup beside a rainy window. A developer opening it next month may need to know:\n\n* Where will the image appear?\n* Which model was used?\n* Can the original task still be found?\n* Were reference files involved?\n* What has been checked?\n* What still needs approval?\n\nThe manifest can stay small:\n\n```yaml\nexample_only: true\n\nasset_id: cafe-hero-03\nfile: cafe-hero-03.png\nplacement: homepage_header\nstatus: staging_only\n\ncreated:\n date: 2026-09-14\n prompt_version: v4\n\nsource:\n model_label: \"\"\n task_id: \"\"\n\nreferences:\n used: true\n files:\n - cafe-cup-reference.jpg\n rights: review_required\n\nchecks:\n desktop_crop: pass\n mobile_crop: pass\n product_details: review_required\n publication_rights: review_required\n\nnotes: \"Leave space on the left for the heading.\"\n```\n\nUse `review_required` when something is uncertain. A blank field or a guess can easily be mistaken for approval.\n\nThe `staging_only` status also matters. The file may be ready for layout testing while its references or publication rights still need review.\n\n## Explain Why a Version Was Rejected\n\nThere is no need to document every draft. Record only why the closest alternatives were rejected:\n\n```yaml\nrejected:\n - file: cafe-hero-01.png\n reason: \"Cup handle changes shape.\"\n\n - file: cafe-hero-02.png\n reason: \"Heading covers the cup on mobile.\"\n```\n\nThis prevents the same comparison from being repeated.\n\nIf the team works with [ZMS AI](https:\/\/zms.com\/) or another shared model workspace, copy the model name and relevant settings shown for the task. Do not rely on memory because names, controls, and available options may change.\n\nAvoid storing private tokens or signed download links in the manifest. A task ID is usually enough to locate the source without exposing temporary access details.\n\n## Test It in the Real Layout\n\nA banner can look fine by itself and fail inside the page.\n\nCheck it on the actual website:\n\n* Is the subject visible on a phone?\n* Does text cover an important detail?\n* Is there enough contrast behind the heading?\n* Is the file too large?\n* Do labels, hands, reflections, or product details look wrong?\n\nIn the caf\u00e9 example, the cup sits neatly on the right in the desktop layout. The mobile crop removes half of it. \u201cImage approved\u201d is therefore not enough; the manifest should record which placements passed.\n\nFor video, check the thumbnail, first frame, last frame, captions, and sound timing as separate items.\n\n## Approval Is More Than Appearance\n\nA polished asset may still be unsuitable for publication.\n\nBefore it reaches production:\n\n* Confirm that every reference may be uploaded, processed, and reused for the project.\n* Remove names, addresses, access codes, private locations, and unreleased client material.\n* Review recognizable people, logos, copyrighted characters, packaging, and generated text.\n* Verify factual and product details with reliable sources.\n\nA generated product shot does not prove that the real product has the same appearance or performance. A generated action is not a safety demonstration.\n\nIf viewers could mistake the result for a real person, place, event, or product test, label it as illustrative.\n\n## Keep the Names Boring\n\nOnce the useful context lives in the manifest, filenames can stay simple:\n\n```text\ncafe-hero-01.png\ncafe-hero-02.png\ncafe-hero-03.png\ncafe-hero-03.yaml\n```\n\nThat is easier to maintain than another folder full of files called `final-final`, and it removes the guesswork around which asset was approved.","published_at":"2026-09-14T07:33:26.000000Z","scheduled_publish_at":null,"is_published":true,"is_shared":false,"updated_at":"2026-09-14T23:00:08.000000Z","edited_at":"2026-09-14T07:33:15.000000Z","translation_source":null,"trend_at":null,"promoted_at":null,"reading_time":2,"points":0,"views_count":12,"clips_count":0,"comments_count":0,"rated_value":null,"promoted":false,"trending":false,"is_draft":false,"is_public":true,"locale_code":"vi","is_video":false,"thumbnail_url":"https:\/\/images.viblo.asia\/07a8a8aa-cdcc-4bd1-8a69-313a38fff024.png","user":{"data":{"id":207484,"url":"https:\/\/viblo.asia\/u\/emily.jones","avatar":"3bffd972-7730-4fb7-b931-2c4f663bb47b.png","name":"emily jones","username":"emily.jones","followers_count":0,"reputation":0,"posts_count":7,"banned_at":null,"level_partner":null,"following":false}},"tags":{"data":[{"slug":"ai","name":"AI"},{"slug":"video","name":"video"}]},"commentators":{"data":[]}},{"id":106654,"title":"Sumclub World","slug":"y0VGwgG0VPA","url":"https:\/\/viblo.asia\/p\/sumclub-world-y0VGwgG0VPA","user_id":214782,"moderation":"discarded","transliterated":"sumclub-world","contents_short":"Sumclub l\u00e0 n\u1ec1n t\u1ea3ng gi\u1ea3i tr\u00ed tr\u1ef1c tuy\u1ebfn quy t\u1ee5 nhi\u1ec1u d\u00f2ng game nh\u01b0 game b\u00e0i, slot, b\u1eafn c\u00e1 v\u00e0 casino.

They discover it after the edit is almost finished.\n\nA track may sound impressive on its own but compete with narration, hide a dialogue transition, place its strongest section under the wrong scene, or create too much energy during a quiet explanation. By that point, replacing the music usually means reopening the timeline and changing several decisions that were already considered final.\n\nThis is why AI-generated music is often more useful as a testing layer than as a final production asset.\n\nThe goal is not to generate a perfect song immediately. The goal is to test whether a musical direction works before spending more time on arrangement, recording, licensing, or post-production.\n\n## Test the timeline, not just the song\n\nA music draft should be evaluated inside the actual project.\n\nFor a video, the important questions are usually practical:\n\n* Does the opening create enough energy in the first few seconds?\n* Does the music leave space for speech?\n* Does the transition happen before or after the visual cut?\n* Does the most emotional section support the scene, or distract from it?\n* Can the track be shortened without sounding incomplete?\n\nA song that works during casual listening may fail completely when combined with voice-over and fast visual changes. The timeline is the real test environment.\n\nBefore generating anything, write down a few constraints:\n\n* approximate duration;\n* target tempo or tempo range;\n* instrumental or vocal direction;\n* emotional intensity;\n* scene changes or important dialogue points;\n* whether the music should lead the audience or remain in the background.\n\nThese constraints make it easier to compare drafts. Without them, every generation becomes a different idea and the evaluation becomes subjective.\n\n## A better prompt describes production conditions\n\nA weak prompt might look like this:\n\n> Cinematic emotional music for a video.\n\nThis describes a mood but not a usable production requirement.\n\nA more useful prompt could be:\n\n> 72-second instrumental track for a technology tutorial, around 92 BPM, restrained electronic pulse, warm pads, minimal percussion, no dramatic drop, leave space for continuous narration, gradual increase in energy during the final 15 seconds.\n\nThe second prompt gives the generator information about duration, tempo, instrumentation, structure, and the relationship between music and speech.\n\nThis does not guarantee that the output will be suitable. It simply creates a better starting point for testing.\n\nA prompt-based tool such as [onlymusic.ai](https:\/\/onlymusic.ai\/) can be used at this stage to create several early variations. The useful comparison is not \u201cWhich track is the most beautiful?\u201d but \u201cWhich version creates the fewest problems in the edit?\u201d\n\n## Mix a rough draft under narration\n\nYou do not need a finished mix to evaluate a draft. A simple temporary mix is usually enough.\n\nFor example, you can combine a narration file and a music draft with FFmpeg:\n\n```bash\nffmpeg -i narration.wav -i music-draft.mp3 \\\n-filter_complex \"[1:a]volume=0.18[music];[0:a][music]amix=inputs=2:duration=longest:dropout_transition=2[mix]\" \\\n-map \"[mix]\" review-mix.wav\n```\n\nThe music volume in this example is intentionally conservative. The purpose is not to produce a final master, but to hear whether the voice remains understandable while the music is present.\n\nWhen reviewing the result, listen at normal playback volume rather than only with headphones at high volume. Also check the first few seconds, the densest narration section, and every major transition.\n\nA track may appear acceptable during a quiet introduction but become distracting when the speaker explains a complex idea.\n\n## Use versions instead of endless regeneration\n\nA common mistake is to generate dozens of tracks without recording why each one was rejected.\n\nA simple version table is more useful:\n\n| Version | What changed | Result |\n| ------- | ----------------------------- | ------------------------------------------ |\n| A | More percussion | Energetic, but masks speech |\n| B | Fewer high-frequency elements | Better for narration |\n| C | Slower tempo | Fits the introduction, weak for the ending |\n\nThis approach turns generation into an evaluation process. It also prevents the team from returning to the same failed direction several times.\n\nAt some point, regeneration stops being productive. If the structure is already usable, editing may be faster:\n\n* cut an unnecessary introduction;\n* lower the music before important dialogue;\n* add a short fade before a scene change;\n* remove a vocal section under narration;\n* automate volume instead of generating another track.\n\nThe best draft is often the one that needs the least repair, not the one with the most impressive isolated moment.\n\n## Human review is still part of the workflow\n\nAI generation can accelerate exploration, but it does not decide whether a track belongs in a specific project.\n\nA human reviewer should check:\n\n1. whether the music supports the intended scene;\n2. whether the voice remains clear;\n3. whether the structure matches the edit;\n4. whether any lyrics are appropriate and authorized;\n5. whether the intended use is allowed under the relevant service terms;\n6. whether external samples, references, or source material create additional rights concerns.\n\nIf lyrics are used, they should be written by the project team or used with permission. A generated result should not automatically be treated as copyright-free or commercially unrestricted. The project owner should verify the current terms of the chosen service and keep a record of the source material and editing decisions.\n\n## The practical role of an AI music draft\n\nThe most valuable result of an AI music workflow is not always an audio file. Sometimes it is a decision.\n\nA draft can reveal that:\n\n* the scene needs instrumental music instead of vocals;\n* the narration requires a slower harmonic rhythm;\n* the opening needs less energy;\n* the final section needs a stronger transition;\n* the project should commission a custom score instead of continuing with generated material.\n\nThat information can save more time than another polished track.\n\nAI music is therefore best understood as a creative test layer. It helps creators evaluate timing, mood, density, and direction before the final production decision is made.
