Start with an outcome, then build a sequence
An Opus video generator brief works best when it has somewhere to go. Before writing about colors or transitions, decide what the viewer should remember at the end. A launch might need to introduce a name and one benefit. An explainer might need to replace confusion with a simple visual idea. With Framecast, the starting material is your written prompt. The result is a motion video in one of three fixed lengths. Keeping the outcome small enough for that length is the first creative decision.
Divide the message into a beginning, middle, and end
Write a short opening that establishes the subject. Give the middle one clear job, such as explaining a relationship or introducing the central benefit. Close with the line you want to leave in the viewer’s mind. You can put this order directly into the prompt. For a fictional gardening project, a brief might move from an empty windowsill to a small growing habit, then finish with “Make a little space for green.” This is a sample concept rather than an example of a generated result. Its purpose is to show a manageable narrative.
Use constraints to make the brief readable
The available durations are 15, 30, and 60 seconds. A shorter choice encourages a smaller message, while a longer one allows additional context. Neither choice removes the need for concise writing. Include exact wording for important names and closing lines. Describe a small color palette and the overall pace in plain language. Avoid contradictory directions, such as asking for a quiet opening and several competing messages immediately. A brief with clear priorities gives you a useful basis for assessing the finished video and deciding which change matters most.
Choose the frame before the job starts
The generator offers 16:9 landscape, 9:16 portrait, and 1:1 square formats. Match that choice to the place you intend to use the video and the shape of your message. A portrait composition needs text that reads comfortably in narrow lines; landscape gives a horizontal sequence more breathing room. Each format produces 1080p MP4 output. The service uses an original music library and includes no voiceover. Keep all essential information understandable through the motion and written content, so the soundtrack can support the story without having to explain it.
Budget for creation and changes
You need a signed-in account and purchased credits to generate. The charge is 100 credits for 15 seconds, 180 for 30 seconds, and 400 for 60 seconds. A chat edit costs 40 credits every time. Monthly subscriptions in USD, tax extra: Starter offers 500 credits for $9.90, Pro 2,400 for $39.90, Business 7,000 for $99.90, and Studio 15,000 for $199.90. There is no free tier. Credits expire at period end without rollover. Your balance is charged before a job starts. If generation ends in failure, the job’s deducted credits are automatically refunded.
Keep the useful version
After completion, watch for the main message first, then assess individual details. Ask for a focused chat edit if the wording or visual direction needs a change. Avoid editing simply because another variation is possible; choose changes that serve your original outcome. Download the finished MP4 within 30 days, because video files are only kept for that period. Cancel anytime with access until period end. Creem refunds claw back that period’s granted credits. Read the pricing and refund pages before subscribing to a plan so the cost and policy are clear.
