File failed QC: Frame count

If your QC report shows Frame count in red, your file's duration doesn't match the duration set for your ad.

Frame count – reading the QC report

• The value next to Frame count is the number of frames in the uploaded file, not the required number. For example, 252.000 means the file is 252 frames long.
• The required frame count is the ad's duration in seconds × the frame rate. For example, a 10-second ad at 25 fps must be exactly 250 frames, so a 252-frame file fails.
• Frame count can appear under both Video and Audio in the report. Both must match.
• Use this table to check the frame count for common durations:

Frame count – what it means

Every ad in a campaign has a set duration. The QC checks that your file is exactly that long, to the frame. Even one frame too many or too few fails.

In countries that need a slate, such as the UK and Japan, the slate and clock are not counted in the ad's duration. For example, a 20-second UK ad with a 10-second slate must be set to 20 seconds in the campaign, not 30.

Frame count – likely cause

This can be a file fault or a campaign error:

• The file is too long or too short, for example extra black frames at the end, or the edit trimmed slightly short.
• The duration entered for the ad in the campaign is wrong, for example 20 seconds instead of 30, or the slate was included in the duration.

Frame count – fix

1. Check the duration of the ad in your campaign first. If it's wrong, correct the ad's duration rather than the file.
2. If the campaign is right, add or remove frames in your edit so the file is exactly the right length. If your ad has mute frames at the start or end, make sure they stay correct (see File failed QC: First Frames Mute or Last Frames Mute).
3. Re-export using the matching Export Guide and upload the file again.

• You’ve exported the file using the specification shown by the View Specs link for the ad in your campaign, but it still fails this check.
