Audio video sync delay planner processes your input in this browser. Inputs and results are excluded from analytics. Recent tools save tool names, visit counts and last-visit times. Saved tools store only their names. Draft saving is optional and stays on this device; delete saved text with the draft controls. Loading text from a URL is optional and contacts that server; its URL and your IP address are visible to the server. An optional “Use in” action keeps a handoff in this tab. The next tool removes it on arrival and ignores it if more than a minute has passed.

Copy link includes the inputs you choose to share in the address. Anyone with that link can reopen them. Files and generated results are excluded. Password and key tools share settings only.

Reset reloads the tool with its starting values and releases open files and device controls. Saved drafts stay on this device until you delete them.

Links include your inputs and settings. Anyone with the link can see them, so leave out private text. Files and generated results are left out; random draws run again.

Using the audio video sync delay planner

Describe which signal arrives first and how many frames separate them. The planner delays the earlier signal by frames divided by frame rate. This plans a correction; it does not change a media file or measure your equipment.

A worked example

If audio arrives 3 frames before video at 30 frames per second, delay audio by 100 milliseconds.

Before you use the result

Frame rate must match the actual media rate. Device buffers, variable frame rates and streaming paths can introduce changing offsets.
