Synchronizing your video and telemetry.
Use this tab to synchronize your video and telemetry, possibly accounting for any video edits. Note: if you are using map-only mode then you may have nothing to do here.
Single Cut
In the simplest case your video has not been edited and contains a single continuous cut. To align the video and telemetry you must find the telemetry timestamp that corresponds to the start of your video. If you have an estimate of this value (e.g., you know you started recording video 45 minutes into the ride), then you can enter this estimate directly and then nudge the alignment using the arrow buttons. The single arrows add or subtract 1 second, while the double arrows add or subtract 15 seconds.
To make sure you've got the alignment right, check how it looks at moments in the video that are identifiable in the telemetry:
Multiple Cuts
If your video has been edited and contains multiple cuts (with temporal discontinuity) you will have to identify them for SUFFERvision so they can be separately synchronized with the telemetry. If you've done the editing yourself you may already know where they are, but otherwise you'll have to watch the video and look out for them (sometimes tricky if there aren't obvious transitions).
For each cut requiring separate syncronization, click the "New Cut" button the moment it occurs. This will add a new row showing the video timestamp of the cut, the currently synchronized telemetry timestamp, as well as buttons for making adjustments, deleting the cut, or seeking to its start. As you watch the video the green highlighting will follow the currently active cut. To avoid confusion you'll probably want to confine yourself to making adjustments on the active row.
Hiding Telemetry
If you would like telemetry to be shown for most of your video, but not shown for a specific cut (e.g., if the cut corresponds to an instant replay in TV coverage, or to time after the race is over), enter -1:00:00 and all data will be hidden for the duration of the cut.
Finish Line and Lap Counting
The last thing to do on this tab (and the only thing that's useful in map mode) is to mark the finish line (assuming your activity is a race and there is a finsih line). Once you have syncronized your telemetry, find the moment in the video where the finish line is crossed and press "Mark Line". Once the line is marked the "Line" display field will show distance to this point (rather than distance to the end of the activity).
If your activity was a criterium or circuit race you may also enter how many laps remained at the moment you marked the finish line (probably zero, but maybe not if you didn't finish the race). This enables SUFFERvision to compute and display a lap counter (soon anyway ... I still need to port the lap counting logic from the desktop version of SUFFERvision).

To make sure you've got the alignment right, check how it looks at moments in the video that are identifiable in the telemetry:
- If the activity has GPS data, look for corners or other landmarks like road or bridge crossings that are visible on the map.
- If the activity has power or cadence data, look for features like sprints at the end of a race, or times when pedaling starts/stops in corners or at the top of climbs.
- If the activity has elevation data, look for hillcrests.

Adding and tweaking activities
If your activity was a race or group ride then you may be able to find data for other participants on Strava, Garmin Connect, or Training Peaks. If so, you can add them here, and, if everyone's clocks are accurate, the other participants will be displayed as properly synchronized dots on the map.
The first activity shown in the list to the left is the primary activity used for setup and synchronization of data. This activity can not be deleted and it is the only one (at the moment) for which SUFFERvision displays detailed data.
If your primary activity comes from Strava then you may click the "+" button to search Strava for related activities and automatically add them. You can also manually enter the URLs of related activities in the text field at the bottom of this tab.
Additionally on this tab you may:

Additionally on this tab you may:
- Override an athlete's display name.
- Choose the color of an athlete's map dot (e.g., to make all teammates the same color).
- Nudge an athlete's time series forwards or backwards by a given number of seconds (for cases where the device clock is off by a little, or maybe by some multiple of hours due to a timezone issue).
- Enter an athlete's weight for use in Watts/Kg calculations (currently only of use for the primary activity).

Display Options
Here you can choose a number of mostly self-explanatory options for how data is displayed.
Drag fields between lists to choose which are displayed and in what order.
Two sets of three colors are provided, one for video mode and one for map mode (since what is legible over the video may not be legible over the map). The first color is used for primary data display, the second is used for displaying maximum power, and the third is used for the power thermometer.

Edit Captions
On this tab you can enter a set of captions with timing information. Currently captions are displayed in the center of the screen and there is no control over positioning or font, though this will likely be coming soon. The format is timing, followed by the caption, followed by a newline, e.g.:

current time with a default display duration of 6 seconds.
