A 35-second video may be rejected because it exceeds the selected format limit, not because the file is damaged. Bumper ads are limited to 6 seconds, auction non-skippable ads cannot exceed 30 seconds, and skippable in-stream ads have no maximum length although shorter videos are usually more practical. Vertical videos under 60 seconds are recommended for Shorts.
Google Ads settings vary by objective, ad format, device and placement. Classify the format before changing the campaign.
The auction non-skippable format may be enforcing the 30-second limit.
A horizontal-only asset or unsafe text placement can cause poor rendering.

The opening lacks a clear value proposition or call to action.
Do not force one size or campaign type onto every objective. Evaluate intent, creative and measurement together.
Bumper, non-skippable, skippable and Shorts formats apply different length rules.
