Yes, when you import a playout log file, it will completely replace the existing log content for the specified date range. This is an important consideration before proceeding with any import.

Complete replacement:

When you import a file, the entire log for the selected date range will be cleared and replaced with the imported file content. This means any existing playout log entries, manually scheduled items, or previously scheduled content within that timeframe will be permanently removed.

Date range scope:

The replacement only affects the specific date range you select during the import process. Content outside your chosen date range remains untouched. For example, if you import a file for a specific day, only that day's content is replaced.

Supported formats:

PlayIt Live supports importing several formats including PlayIt's own Playout Log Format (pipl) and M3U playlist format. Each format allows you to specify the exact timeframe for replacement.

Safety considerations:

Before importing, ensure you have backups of any important existing content within the target date range. The import process cannot be undone, so any custom scheduling, voice track placeholders, or manually placed items will be lost if not backed up.

Review before applying:

When importing via Manage > Playout Log, you can review the imported content before applying changes to your playout log. However, importing directly through the main interface will immediately take effect without a review step.

Always double-check your date range selection to avoid accidentally replacing more content than intended.
