Hello my sunday driver, Today i'm going to explain how sync the telemetry overlay graphics and the onboard camera using the video editing software Adobe Premiere CS5 / CS6 / CS7 / CC (CS4 NO COMPATIBLE)

First off we need to acces to the config are in our session through the 'wrench icon'



At the very bottom we find the download overlay table which is divided into different stints, be careful to choose the right one



I personally prefer (even if it is slower) to generate and download each of the graphs individually (in this case, speedometer, map and g-meter) so this way i can manage each element in the right places, if we choose to generate all graphics at once, we will get a video with all "welded" with no chance of adjustment


For this example, i'm going to download just the speedo and the map and leave the g-meter, the phone was inside pocket and that make to the accelerometer to get wrong / weird values so not worth to include in the video


The generated =16pxfiles are compressed files ZIP format, we will find as many SWF (flash video) files as laps we did for that stint, the file name reflects the lap to wich it belong.

Before start to work with Premiere, its recommended to create a folder with the video onboard, al telemetry videos uncompressed and others stuff like logos, music, cover images....



For this example I'm going to use Premiere CS7 also know as Premiere CC , anyway this tutorial is likewise valid for previus versions as there are few changes regarding option that are going to use, lets go!

=39pxGENTLEMEN START YOUR ENGINES

So start premiere, Create New Project, set a name and then create a sequence with the video parameters, conmmonly 1920x1080 , 30 fps







Once we have created the sequence, we need to import all the files, right click -> Import




After drag the video onboard to channel 1 ( This way we left chan 2 and 3 free to the telemetry) it's time to sync the telemetry with the video onboard, This involves to place the video at the exact moment when we cross the start/finish line, In the example video, the line it's far away (left image) so i need to move forward as far as i think (right image)



So now we are over (or near) the line and we need to drag to channel 2 the first lap (SPEED_L1) of the speedometer just in that place, press the play button and carefully look the sync, we need to look just to the speedometer needle and the sound to get an idea if telemetry is going ahead or delayed, in some low-end computers the preview may not work smoothly and can be hard to sync due to slowdowns and freezes, we can solve this changing the image quality to "1/4" using the dropdown indicated in the image, if you still getting bad performance you can disconnect the image of the video onboard pressing the "eye" icon indicated in the very bottom of the image, this will boost the preview speed and will be enough to sync sound and telemetry




When you move the telemetry (purple bar in the image) a box appears showing how many frames you are moving forward or backward, anyway we will reach a point where we need to need more accuracy and make smaaaalll movements to synchronize perfectly both channales, to increase the accuracy and make smallest movements we should decrease the zoom bar at the very bottom of the image, in this animation example we can view how goes from 19 frames movements to 1 frame movement




Once we get audio and telemetry synchronized, we just need to pu the following giles one after the other, where finishes the first lap , beginns the second lap and so on, also we should to do the same process for the map (MAP_L1, MAP_L2...) so our timeline should look like that:

Note: it's possible that some lap remains not completely synchronized due some reasons like poor gps signal, video camera failure or frame drop, in another tutorial i wil try to explain how to solve this kind of mismatches





Obviusly we will not let the graphics in the center of the image, need to move and resize both, in this example i'm going to click over the purple bar SPEED_L9, at the left of the screen i get a set of controls that will affect to this clip, deploying the motion tab we access to the size and position settings, just have to put a number with the keyboard or modify with the mouse, pretty easy




Once we have the graphic in the right place, we press right click over motion tab and then Copy , then we will go clip to clip (SPEED_L1, SPEED_L2, SPEED_L3...) pasting the setting, that way all graphics we will be equal, to paste settings we need to right click at an empty zone and press Paste , the speedometer will take the posotion and the size right away




Last 2 steps are needed to the MAP graphic aswell (and also to a G-METER if we are using that graphic too) in the same line , we should to move the map to the desired position and size, copy settings and the paste to the others clips (MAP_L1,MAP_L2... )

To export the final edit we need to go to the Render Area
File -> Export -> Media

If target its Youtube, at format whe should choose H.264 and set the Preset to YouTube HD 1080p 29.97fps, this preset will ruin a lot the quality video but that it's the maximum quality that youtube accept at the moment, if you want to keep this video in your hard drive aswell i recommend you to make an aditional render with high quality settings like HD 1080 28.97fps preset
 

First off, I want to remind the use of the search box (in your profile, not here in the forum)  to ensure that the track  or stretch you want to create does not exist in the database , you can enter the track name, city, town or postal code to attempt to locate in the current database

I will explain briefly, with graphic examples, how to make the  start / finish and sectors  linesand highlight certain details to make everything work

1 - Find the target

The first thing to write is the city  which the track or stretch belongs , we can also use coordinates, not much more to say, this step does not have much of mystery



2 - Trigger  Lines

Next we have to create trigger cut lines, these lines are used to determine the sart/finish line and the intermediate lines, if we are creating a stretch or hillclimb we  have to specify both  lines  the start line and the finish line .

To create a line just determine where we want to start the line(click 1) and where we want to finish it(click 2), these points can be adjusted later, once created an additional  point automatically appears in the middle of it, this point is used to specify the driving direction  and avoid false positives and common problems.




Some GPS  have a considerable margin of error which "can get us out"    several meters away where we really are , that is why we must create GENEROUSLY WIDE lines  to maximize the possibility to  trigger always the  lap  (even if we have a bad GPS) , on the other hand, when you are create the start/finish line on a racing racing, do not forget to inclue the pit lane aswell



3 - Track Specs

Once created the 3 trigger lines  (4 lines if you are creating a strech) you only need to fill the track info (name, distance, whatever) and save the changes, the track will appear on your mobile under the tab " own circuits " , anyone who visits your profile (if you are a public profile) will see your tracks and and will be able  to add they to his own database , so other users can race and compete at "your track"

BEST!

Antes de nada, quiero recordaros que uséis el buscador para asegurar que el circuito o tramo que queréis crear no existe en la base de datos, podéis introducir el nombre de circuito, ciudad, pueblo o código postal para tratar de localizarlo

Paso a explicar brevemente, con ejemplos gráficos, como se crean las líneas de corte, de salida/meta y de sectores, en la creación de un circuito, y hacer hincapié en ciertos detalles para que todo funcione lo más mejor posible...

1 - Localizar el objetivo

Lo primero que debemos especificar es la ciudad a la que pertenece el circuito o tramo que queremos crear, también nos valen las coordenadas, poca cosa más que decir, este paso no tiene mucho misterio



2 - Líneas de corte

A continuación nos toca crear las lineas de corte, estas lineas servirán para determinar la meta y sectores intermedios, en caso de tramo o hillclimb, habrá que especificar tanto la linea de salida como la de llegada.

Para crear una línea tan solo deberemos determinar donde queremos que empiece (click 1) y donde queremos que  acabe (click 2) , estos puntos pueden ser ajustados posteriormente, una vez creada la linea aparece automáticamente un punto adicional en el centro de la misma, este punto se utiliza para especificar el sentido de la marcha y evitar falsos positivos y marrones varios.




Algunos GPS  y móviles tienen un margen de error considerable (por no llamarlo de otra manera)  que puede "sacarnos" de la trazada y situarnos bastantes metros más allá de donde realmente estamos, es por esto que debemos de crear las lineas GENEROSAMENTE ANCHAS para maximizar la posibilidad de que siempre corte vuelta, aun que tengamos una piedra por GPS, por otro lado, cuando creéis linea de meta en circuitos, no olvides de contar también con el carril de boxes



3 - Ficha Técnica

Una vez realizadas las 3 líneas de cruce (4 en caso de tramo) nos queda tan solo rellenar la ficha del circuito y guardar los cambios, el circuito aparecerá en vuestro móvil dentro de la pestaña "circuitos propios" , cualquier usuario que visite vuestro perfil podrá ver vuestros circuitos y añadirlos a su propia base de datos, de esta manera otros usuarios podrán correr en "tu circuito"
