Test the same exported file through another output path before moving the soundtrack. Wireless playback, editor buffering and device configuration can affect perceived synchronization. If the file aligns on a wired or built-in speaker path but looks late only on one device, investigate playback latency first. Do not offset the approved master to compensate for one reviewer’s headphones without evidence that the encoded timeline is wrong.
Choose a visible and audible anchor
Use a clap, impact or another source event with a clear relationship between picture and sound. A flowing dance gesture may not occur exactly on the musical beat, so it is a weak latency test. Keep the reference and export interval unchanged while switching the playback output.
Adobe’s audio-hardware guidance includes device and latency considerations. Follow the actual application and device settings. This is a playback diagnosis, not a promise of a particular wireless delay value.
Compare without editing the file
- Play a short exported synchronization test through the current device.
- Play the identical file through a wired or built-in output path.
- Compare the same visible-audible anchor, not different moments.
- Check whether the delay is constant or grows through the clip.
- Change project timing only if the evidence shows a file-level problem.
If the delay grows over time on several devices, investigate source timing, edits and export rather than assuming a fixed playback offset. The variable-frame-rate guide addresses a different possible source of progressive mismatch.
Keep review notes precise
Record player, output device and the tested anchor. A note saying BGM late does not tell the editor whether the problem occurs in the rendered master, a streamed preview or one headphone path. Request a reproducible interval before retiming a full sequence.
Should I trust the editor preview or the exported file?
Inspect the delivered file on the intended playback path. The editor preview helps locate errors, but its device settings and performance can differ from delivery. Use both observations rather than treating either as universal proof.
Can I add a delay correction for the venue?
If the venue system needs a documented playback compensation, keep that as a separate screening configuration or clearly named derivative. Retain the approved synchronized master so ordinary viewers do not inherit a correction intended for one installation.
