BROWSE CATDV SUPPORT MANUALS

For server-triggered tasks you use the ‘Server Query’ tab to specify a query that will be performed to find matching clips for processing. You can also specify a check interval, and whether only to process clips which have a file which is currently online and accessible. If you specify a root folder, only files within that folder are processed, and that folder is used when calculating relative paths (see below).

Queries are defined in the same way as advanced queries in the CatDV client. If you specify multiple query terms (for example, based on clip status, on modification date, and so on) they must all be true for a clip to be processed unless you check the ‘OR’ box, in which case just one of the OR terms needs to match. Check the ‘NOT’ back to invert that condition (ie. match all clips for which the condition is not true).

Just as with watch folders you should take care that you don’t specify actions that will be performed in an endless loop. For example, if you have a server-triggered action based on clips whose status is “To be converted” you should update the status to something different such as “Completed” on successful completion in the post-processing stage. By default, the worker will only process each clip once per session but you can override this if required by checking the “allow polling” option.

Each clip that matches the server query will be added as a separate task into the task queue (as there could be a large number of files that each requires a lengthy transcode). If you perform an operation such as exporting an XML file on the Conversions tab it will therefore export one clip at a time – see the section below on ‘Batch operation’ if you want to export all the matching clips in one go.
