This was one of our biggest vMix productions yet, utilizing 10 cameras in and around the track and .xml timing data feeding custom-designed GT Title templates. The broadcast aired live in Canada on CHEK Television and RevTV, along with Speed Sport in the US.

https://www.facebook.com/1091684...8/videos/323312732245564 (live race coverage beginning at 1:00:00)

Here's a gear list for those who are interested:
Broadcast cameras - JVC HM620 (4), GoPro Hero 7 (5)
5.8 GHz Wireless Transmission (infield cameras) - CineGears 2000m Kit
Cellular Transmission (in-car cameras) - LiveU LU200
Drone Camera - DJI Inspire 1 (HDMI out from controller)
Crew Communications - Unity Intercom

This was our first stock car race as a crew, so definitely a steep learning curve but very happy with the end result for more than 35,000 social media viewers and another 115,000 on traditional television. Would love to hear everyone's thoughts on how to improve for the next one!

@ rollfocus

Awesome job guys!
I am curious to know more details on how you handled the leader board graphics.
(I did find the colouring and the font size a little hard to read on the small screen, but overall I am very impressed)

Keep up the great work.

Thanks for the kind words!

Agreed - the font/colour combo didn't translate very well to the 3.5mbps stream, but they came across nicely in the televised production. Here was our workflow for the leaderboard (and all other graphics with live data)...

- Created the shape elements (background bars, flags, sponsor icons, etc.) in Photoshop and imported into GT Title Designer
- Once we had access to a sample data feed from MyLaps (the race timing provider) we added text placeholders in GT for each piece of information we wanted to include
- Then we painstakingly animated each element (more than 150 total for the leaderboard) to appear on screen in sequence, taking advantage of layers, masks, and delay timing to achieve the end result
- Once the design and animation was complete, we pulled the GT graphic into vMix and loaded the MyLaps .xml file (updated once per second by the scoring computer) into Data Sources Manager
- Then it was another long afternoon of linking the data fields to each of our text placeholders and testing to ensure the correct data was showing up

We repeated that process for the race ticker and also created a separate Excel spreadsheet linked to the current flag colour (green.png, yellow.png, chequered.png) and desired sponsor so our graphics operator could quickly and easily update other elements of the graphics package in a matter of two or three clicks.

Let me know if you're curious about any other elements of the show!

@ rollfocus

Nice

A few observations based on your explanation if I am allowed :


Quote:
animated each element (more than 150 total for the leaderboard)

Did you actually animate each bar and each individual textfield or did i understood it wrong?

Quote:

Was it not possible to "Apply to all fields in this title" with your DataSource?

Respect though

That's essentially correct @doggy... once we created the first line of the leaderboard we were able to copy-paste for subsequent rows, but in order to get the cascading animation we were after, each individual element's animation timing had to be adjusted (by +/- 0.05 seconds per row in this case).

And because each data point (name/car number/lap time/top speed/difference) was serviced by a different cell in the .xml output (rather than all in a single line, as presented) we had to assign the data sources for each individual field. Unless I'm missing something, that was the most efficient way to achieve our end result.

What if every line/row was on it's own layer and animated the layer?

Must be misunderstanding: are you saying the data per driver was not in a logical row in the datasource itself with the individual data in a columns (when xml imported in the datasources)?
Can you provide an example (or part of ) such xml file ?

That's the solution we would have loved, but as far as I can tell GT Title Designer doesn't allow you to mask layers, so instead of having the drop-down animation (with the layer hidden as it drops in) we would have to settle for each row flying in from the top of the screen... not the look we were after.

Quite possibly - my experience is still somewhat limited using Data Sources Manager. Below is a link to a sample .xml file from MyLaps - would love to learn of a more efficient way to populate data fields for large graphics like this one.

The quickest way to link title block to a data source is to have the textblocks in your title have the same name as the column headers of your data source.
That way you just have to select the data source and leave the Columns specification to Auto.

Checking the "apply to all fields" will connect the rest in your title

For rankings (or multiple rows in one title ) you might consider converting the rows to columns in the data source setting ( check how they are named then, before the period, after is the "row" !)

If the source files are long and need for example only the top five one can add filter to the xpath like //result[ not(position > 5)]

Time spend prepping a title with proper names save a LOT filling it with data :-)

Ah, brilliant - in this case we designed the titles before knowing with that xml columns would be, but that's easy enough for next time around to get a sample data file and build from there. Thanks for the tip @doggy!

Small warning

If you have other textfields not related to the data source , they also will be connected (randomly) when using "Apply to ..."so after connecting the ranking data , disconnect those fields form the rank datasource and specify their content
Also make sure you have no "empty" rows or less than in your title in your data source

Very nice show you put up!

How many people were involved in the production, and what did they do?
