Kling 3 camera moves look expensive until social apps squash them. 4K in is the cheap way to keep edges after upload.
Kling 3 usually lands at often 720p–1080p. That is enough in the generator. It is not enough after Instagram, TikTok or YouTube compress the file again.
Free: 3 upscales a month. Creator launch: $9/mo locked in (was $19). 20 minutes of 4K video. Studio: $39/mo.
