GPS playback

[Bman]

I suppose Electric Cafe is the best place for this.

Basically I want to playback my GPS routes showing Elevation, Speed, Heartrate, Distance etc. Ideally in a graphical form, so I can do things like this :

I used the Garmin website to do that. See here: http://connect.garmin.com/player/11273664

But I want it to playback at actual speed, for maximum accuracy. Garmin's "turtle speed" is way too fast.

The best alternative I have found so far is Topofusion.com http://www.topofusion.com/images/playback08.gif But that adds extra data fields that I dont really want.

Does anyone use a program to playback their rides?
Can anyone suggest a better alternative?

Looks good Bongman. Do you know what speed Garmin plays the info at, perhaps you could half the speed in Windows Moviemaker or something.

No. But I suppose I could time it and work it out. Besides I just use Virtualdub to slow it down until its the same length as the main movie. As you can tell, its nowhere near perfect. Still pretty cool though

write one

I could if i had time, how much do you want to offer me to knock you one up

I know there is an application for OS X that does exactly what you want, what it's name is escapes me, but there is probably something similar for windows.

I have thought about it and I still may need to resort to it.

I'm sure I could do it in VB. The TCX files I export from my Garmin are in text format. Its just a matter of maths then getting the values to manipulate some graphics.

But if someone has already done this.....

This guy has done it with a java application, so it is possible.

nah, use google maps api (possibly via javascript)

Looking into the google API now.... It looks like thats exactly how the bloke gaz suggested has done it.

I havnt written much JS previously, as I prefer VB, but its not that different.

After seeing Bongman's video on youtube, it got me to start on my own little version by making a small app that converts GPX(/TCX) to SRT(etc) that can be played as a subtitle with the video. Sadly not many timeline based post processing applications will retain the subtitle once it is cut up (including Windows Movie Maker).

Bit more info in the youtube description.

Not too much hassle to do a raw output "burning" the subtitles into the video, and then post-processing (that's if you want to do that of course), but it's not exactly what even I would want to do every time.



I have a question for anyone that wants to do this...
How would you want to sync the video to your GPS stream?
On mine above I saw myself in the video press the start button, sometimes I hear it beep, could also press start on video and GPS at the same time, since the GPS time needs to be offset for the subtitles. Unless you are lucky enough to have a time code on your video (but I think time codes printed on the video is ugly and I would never rely on the creation time of the file, although this is an option for people with decent units).



I don't see there being many "professional" solutions for this, as any serious person wanting to do this, will use a unit to overlay it directly onto the recorded video.



Anyone know of post processing software (editing etc not just encoding) which will accept any kind of data stream?



/edit
The Java app, I think is VOBSUB (like dvd subtitles, they aren't actually text, they are images) overlaid onto the video like I am doing with my text srt ones (I just lack the graphics).
I think it's vobsub because it's "ugly", the jagged edges are hallmark of rubbish dvd titles.
