Kling Video V2.6 Pro Text to Video: write the sound into the prompt (5s, 10s, 1080p, 70cr)

Q: What happens if I omit audio from the prompt?

You still get audio. `audio` is true. The mix will be the model's guess. Name speech, music, and room, including when you want none of them.

Q: Can I upload a first frame?

Not as this row's contract. `requires_image` is false and the category is text-to-video. A first-frame job is a different slug.

Kling Video V2.6 Pro Text to Video has native audio. A silent prompt still gets a soundtrack you did not choose. The description is "Professional text-to-video with Kling V2.6 Pro." audio is true. Durations are 5s and 10s. Max output is 1080p. Credits are 70. No image required. If you do not name the sound, Kling will name it for you — room tone, music, crowd, a line nobody on the brand team wrote.

This is not the 4K V3 text-to-video row. V3 is 3s–15s, 4K, 210 credits. V2.6 Pro is the 1080p pair at 70. The Kling roster has both. Best Kling model is the family ranking. This page is only V2.6 Pro text-to-video.

Write the room into the prompt

Native audio means picture and sound land together. That is useful when you want a door close, a line, a street. It is expensive when you wanted a mute plate and got a sax solo.

Put the soundtrack in the brief:

dialogue, quoted, or "no speech"
music present or absent
foley you need (footsteps, fabric, traffic) or "quiet interior"

A prompt that only describes camera and wardrobe is unfinished on this row. The AI video generator will still return a file with a mix. Caption later; do not treat captions as the first time anyone thinks about words.

If you needed a silent 1080p plate to score in an editor, say "no music, no speech, ambient only" — or pick a row where audio is false.

70 credits is the first five seconds

The price matrix on the snapshot bills a 5s base at 70 credits and each extra second at 14. The listed durations are 5s and 10s, so the 10s take is the 5s base plus five extra seconds. Do not "just try 10s" because the UI offers it. Try 5s until the sound and the blocking are the ones you would ship. Then pay for 10s.

Qualities listed: 1080p only. Aspects: 16:9, 9:16, 1:1. Frame rates: 24fps, 30fps, 60fps. Motion levels: Low, Medium, High. Styles: Cinematic, Documentary, Abstract. Use those. Do not prompt 4K on a 1080p max.

Requires no image. Text is enough. If you already own a locked still, this row will not treat it as frame one. That is image-to-video.

Two lengths, professional, not a studio

"Professional" in the description is a tier label, not a pipeline. You still caption, crop, and publish somewhere else. You still change rows when the next shot is a talking photo or a 4K hold.

Best text-to-video and best model with audio are the category lists. Best 1080p video is the resolution list. This row: native audio, 5s or 10s, 1080p, 70 credits.

Write the sound. Then generate.
