GPS Graphic Overlay GPS-related graphics onto the video. Daniel F GPS File The fullpath of file containing location (GPS) data. Supported extensions: .gpx, .tcx. Time offset in seconds Most of the time this will at least need to be set to the timezone difference between the 2 files plus some seconds if the video recording device isn't precisely set to correct time. GPS time is always exact and in UTC. Use positive values if GPS is ahead of video and negative otherwise.]]> Smoothing level A value of 1 does not smooth locations, it only calculates the extra fields (speed, distance, etc), it also interpolates missing values for heart rate and altitude.]]> Speed multiplier Sample values: 30 for 30x timelapse, 0.25 for 4x slow motion footage.]]> GPS location/track,Altitude,Heart rate,Speed Graph data source What data from the GPS file is used for drawing Basic 2D map line (for location) or 1D graph per time (others),Zoom in onto the map/graph centered on current location,Draw speedometer Graph type Speedometer is available for all data sources but recommended only for speed; for the map type it represents the "percentage done" from trimmed start - end).
Note: for type 1 (zoom and center, aka "follow the dot"):
* crop values are only valid as a percentage and only the bottom (resp left) values will be taken into consideration as both values (ie: bottom/top) will need to be equal to keep the dot centered)
* if data source is not GPS location, the centering will only be done for horizontal axis (time), vertical axis crop will behave just like for the basic 2D map line (it will statically keep the same min/max limit allowing the Now dot to move up and down).]]> Trim start (%) Note: both Trim start and Trim end are computed from the total file, so trimming 50% start and 50% end will result in trimming the entire file.]]> Trim end (%) Note: both Trim start and Trim end are computed from the total file, so trimming 50% start and 50% end will result in trimming the entire file.]]> Percentage from min..max,Absolute value Crop mode horizontal Crop left and Crop right values.
Note: for the horizontal type, absolute values are the longitude (for the location source type) and time (in milliseconds since epoch) for the rest of the data source types)]]> Crop left The value is interpreted either as a percentage of total or an absolute value depending on crop_mode_h. In percentage mode, the values are not restricted to 0-100 to allow for "zoom out" behaviour (ie: cropping -50 left will add an extra half of the total horizontal distance). Values over 100 (in % mode) will effectively not display anything. If Graph Type is set to Speedometer, all crop left/right values are ignored.]]> Crop right Crop left but for the right side, and percentage type is interpreted as an inverse percentage (ie: 100 = do not crop anything). Values under 0 will effectively not display anything.]]> Percentage from min..max,Absolute value Crop mode vertical Crop bottom and Crop top values.
With an absolute value, it can zoom in to between 100 and 150m of altitude to show small changes in altitude between those 2 values better.
Note: for the vertical type, absolute values are latitude degrees (for the location source type) and altitude, heart rate, speed for the others interpreted as the Legend unit type where applicable (ie: a value of 10 for altitude will be considered meters by default but if changing Legend unit to feet it will mean 10 feet).]]> Crop bottom The value is interpreted either as a percentage of total or an absolute value depending on crop_mode_v. In percentage mode the values are not restricted to 0-100 to allow for "zoom out" behaviour (ie: cropping -50 bot will add an extra half of the total vertical distance to the bottom). Values over 100 (in % mode) will effectively not display anything. If Graph type is Speedometer, this will set the minimum needle position which will clamp all values that are lower.]]> Crop top Crop bottom but for the top side, and percentage type is interpreted as an inverse percentage (ie: 100 = do not crop anything).
Values under 0 will effectively not display anything.]]> One color,Two colors,Solid past - thin future,Solid future - thin past,Vertical gradient,Horizontal gradient,Color by duration,Color by altitude,Color by heart rate,Color by Speed,Color by Speed (max 100km/h),Color by grade (max 90 degrees),Color by grade (max 20 degrees) Graph color style See the documentation about the various styles available Color 1 Sets the color #1 for the graph line Color 2 Sets the color #2 for the graph line Color 3 Sets the color #3 for the graph line Color 4 Sets the color #4 for the graph line Color 5 Sets the color #5 for the graph line Show Now dot If graph type is speedometer, this affects the needle.]]> Now dot color Sets the color for the Now dot Show Now text The Legend unit value will be appended at the end and it will be used as the current unit (if a valid unit is found ie: kilometers if "km" is found anywhere in the Legend unit string).]]> Rotation Rotate the entire graph rectangle. For speedometer type the text stays horizontal. Line Thickness (px) Sets the thickness of the line graph in pixels. Draw legend lines with small values each corresponding to the current data source value at 0%, 25%, 50%, 75% and 100% of current graph shown, affected by the Legend unit type if applicable, and with the string appended to the value. For speedometer type this shows division values (but without appending unit).]]> Legend unit m,meter,km,kilometer,mi,mile,ft,feet,nm,nautical,ms,m/s,meter per sec,km,km/h,kilometer per hr,mi,mi/h,mile per hr,ft,ft/s,feet per sec,kn,nm/h,knots,mmin,m/min,ftmin,ft/min Default is meters and km/h respectively. The unit is matched anywhere in the string so extra spaces can be used to tweak displaying.]]> Show dots only This will effectively show the individual data points as affected by smoothing (ie: for location data it will display each GPS fix if smoothing is 1) and can either be used as a cool effect when zoomed in enough or to debug unexpected line jumps.]]> Graph rectangle Format is: "X Y W H". X, Y, W, H are assumed to be pixel units unless they have the suffix '%'.]]> Background image Paths starting with the "!" character are ignored. TIP: use a map image to add context to the GPS track.]]> Background scale Values smaller than 100 zoom into the image, values larger than 100 zoom out. 0 hides it.]]> Background opacity GPS start time Date and time of the first valid GPS point. Video start time Date and time of the video file. Auto offset start Provides a helper offset to guarantee start of video file syncs with the start of GPS file. Correctly sets the offset if video file and GPS recording was started at the same time. Auto offset now Provides a helper offset to sync the first GPS point to current video time (it is updated every second). Correctly sets the offset if your video record the moment GPS starts. Map hint Returns the middle latitude and longitude coordinates of the gps file.
