When working with file sources, you can enable or disable a video preview, effectively making it real time or faster than real time.

Figure 1. Real time or Faster than real time preprocessing.

This is an example of the KlvInjector usage for csv (comma-separated values) metadata insertion.

Select a Session Config and set a file source related parameters:

Figure 2. File Video Source parameters configuration. KlvInjector will perform detection on the selected video file.
Note
Only MPEG TS format is currently supported. If your file has a different format, you'll be prompted to transcode/remultiplex it. For more info on file transcoding please see Video Transcoding. section.
Configure Data source related parameters:

Figure 3. File Data Source parameters configuration.

KlvInjector will perform detection on the selected data file to insure that the file format is supported. For more info on supported data file formats please see Supported Data file formats.

Configure Preprocessing parameters:

You can add a template file to add/merge or remove specific entries.

Figure 4. Preprocessing parameters configuration.

For more info on metadata preprocessing see Metadata Preprocessing.

Configure KLV insertion parameters:

For more info on timing setup see Timing Configuration.
Configure File Target parameters: You can select segmented (by size/time) recording if needed.

Figure 6. File Target parameters configuration.
Close Session Config window and start recording session.
