Exclude parts of your references

You must have exclusive rights to the references for which you turn on Content ID matching. If your reference includes content you don’t own the rights to, you need to exclude those segments from Content ID match consideration. Examples could include:

• Public domain footage
• Short clips used under fair use principles
• Commercial breaks
• Non-exclusive audio loops
• Other examples of content that’s ineligible for Content ID

You can exclude segments from your references using Studio Content Manager or content delivery templates.

Use Studio Content Manager to exclude segments

If you uploaded a reference that includes content you don’t own the rights to, you can exclude the segments using Studio Content Manager:

1. Sign in to Studio Content Manager.
2. From the left menu, select Assets .
3. Click the title of the asset you’d like to update.
   • Note: You can only exclude segments from assets with one or more active references.
4. On the Asset details page, click References from the left menu.
5. Click the row of the reference you’d like to update.
6. Under Existing and pending exclusions, click EDIT.
7. Click ADD ADDITIONAL EXCLUSION.
8. Enter the timestamps of the segment you want to exclude from the reference.
   • To view the segment that starts and ends at the timestamps you entered, click the play icon .
   • To exclude other segments, click ADD ADDITIONAL EXCLUSION again and enter the timestamps.
9. When you’re done adding exclusions, click SAVE.

Use content delivery templates to exclude segments

When delivering new reference files using “Web Video - Reference Only” spreadsheet template, you can add reference exclusion intervals to specify what segments YouTube should exclude when Content ID matching. You can also update existing manual reference exclusions using the “Reference - Management” spreadsheet template.

In the spreadsheet templates, in the column labeled reference_exclusions, enter the time interval in the format MM:SS-MM:SS. For example, “00:00-00:10” indicates the first 10 seconds of the reference should be ignored during Content ID matching.

To exclude more than one segment, use a pipe character ('|') to separate each time interval.

In addition, you can remove already existing manual exclusions using the “Reference - Management” spreadsheet template. Use the column clear_reference_exclusions and set the value to yes to clear out existing exclusions. This does not apply to the exclusions coming from reference overlaps or invalid references. Note that if you specify reference exclusions in the reference_exclusions column and you set “yes” in the clear_reference_exclusions column, no updates will be made.

Propagated exclusions

If you deliver a reference that’s identical to a reference you’ve already delivered, reference exclusions (overlaps and manually created exclusions) are automatically copied from the existing reference to the new duplicate reference.

These exclusions, known as “propagated exclusions”, also get copied from the new duplicate reference to the existing reference. In both cases, the exclusions are propagated only if duplicate references are delivered on the same asset as the existing reference.
