| How To: Use Multiple Data Input Files How To: Use a GPS-Enabled Camera with an Additional Data Input File RaceRender supports multiple input data files at the same time, and each data display object has an "Input" selection that you can set to one data file or the other.
This situation will require a little more setup from you if you want to display data from both files. It really comes down to how you want to use it...

- 1) If using a GPS-enabled camera, be sure that the camera is turned on and has a GPS fix before you start recording. This helps its data and video recordings be in sync with each other so that you hopefully won't need to manually synchronize them in RaceRender. Some cameras will have better results with this than others.
- 2) Add your primary video file to a new blank project.

- a) If it contains embedded GPS or other potentially usable data, RaceRender will ask if you want to extract and use the embedded data from it:

- i) If you also have a more preferred data file that provides better GPS data, then you could just choose "No" here, which will make this act as a normal video file.
- ii) Otherwise, or if you want to use the GPS data from the camera for any reason, then choose "Yes", and the data overlay template menu will appear...

- 1) If you have another data file that you want to use for most of your displays, then you'll probably want to just Cancel out of this screen so that it doesn't create any displays for the camera GPS data right now (we'll get to that later).
- 2) If you want to use your camera GPS data as the primary data source, then make a selection from this menu and it will create displays for it. Keep in mind that any G-force or lap time displays would then be based on the GPS data, so if you have another data file that provides better data, you may want to switch the Input selection on these displays later.

- 3) If your video file did not contain embedded GPS data, then add your primary data file to the project now... If your video was from a GPS-enabled camera but its data was just provided as a separate file (instead of being embedded in the video file), then you may opt to add that data file now. Otherwise, add whichever file is your primary data file.

- a) You should be shown the data overlay template menu...

- i) If you have another data file that will be used for most of your displays, then you'll probably want to just Cancel out of this screen so that it doesn't create any displays for this data file right now (we'll get to that later).
- ii) If you want to use this data file as the primary data source, then make a selection from this menu and it will create displays for it.

- 4) Add any other data file(s) to the project now.

- a) If you hadn't made any selection in the previous data overlay template menu, or otherwise created any displays for your previous data inputs, then you should be shown the data overlay template menu, where you can now make a selection.

- 5) Go through the displays listed under the "Display Objects" section, and double-click to open the properties box of any items that you want to display. You can then set the "Input" selection to make it use the desired data input. Also be sure to look at the "Active" selection to ensure that this display is not hidden.
- 6) If you wish to add any additional displays, click on the "Add" button under the "Display Objects" section, set the "For Input File" selection at the top to your desired data input file, then use the menu to choose the desired display type and style. After it is created, you can use its properties box to choose the data "Field" it uses, as well as customize certain colors, sizes, labels, etc.
- 7) Now use the "Synchronization Tool" or "Side by Side" sync tool to synchronize each of your data inputs to the video.

- a) If you have GPS data that was recorded by your video camera, then that may already be in sync with that video, in which case you could move on to synchronizing the other data file(s) that you added.
- b) There is a Data Sync Wizard that can help speed up syncing these data files:

- i) Select the data input file that you want to synchronize, click on the "Synchronization Tool" button, and then click on the "Data Sync Wizard" button.
- ii) The input you selected should already be selected for the "Step 1" section, so take a look at "Step 2"... You'll want to choose a data event that occurs in both this selected data file and is visible in your main video.
- iii) Use the main preview controls to seek the main video to where it shows the event you have selected.
- iv) Click the "Syncrhonize Data Event to Current Preview Time" button, and your data file should now be in sync with the video.
- v) If you need to synchronize another data file, select it in the "Step 1" section of the wizard, and then repeat these steps 'ii' through 'v'.
