I am deriving gradient and distance from the gpx. Rlv is the mapping from distance to video frame.
#Using rlv in goldencheetah software
I'm using golden cheetah for training software so not limited by some tacx software.Īll I'm doing is creating a new rlv for the old video. I figured these old dvds can still have a life if I could resynchronize them and they sort of do now.
#Using rlv in goldencheetah full
I am simply riding gpx files so I have full location data. I'm not a fan of the re-routed at the end of the stelvio climb from Bormio. I'm a little worried that if I ever visit these places I'll be disappointed by how things have changed since these videos. Lots of interesting older cars looking sparkling new. Im kind of curious to see what he has done, those early RLVs were made with very primitive tools really, it was before strava & accurate GPS data etc, now we use incredibly accurate inclinometer data, our grades are I think by far the most accurate you can have as we even record those grades often at incredibly slow speeds now. Obviously, if you ride a film & using your recorded data this will never link up again with the actual film as the original film will have a very different speed then you & thus it will seem massively out of sync. The grades should be in sync with the film if you run it inside Fortius software but there will not be any map data. Mike if he has a pgmf file for it it must be for the old Fortius Software, so the film in the question of the Mortirolo must be older then 2007. Seems to work well at that point and lets me ride the actual gavia pass instead of something a bit too short. I'm replacing the pgmf with my own gpx (gps route file) and rejiggering the rlv so the distance->video mapping matches the gpx. The tacx files for the a consist of an rlv (distance to video frame mapping), a pgmf (distance to slope mapping) and an avi (video). I'm not talking about making a new video but adapting older tacx video to work as a more 'modern' virtual ride simulation, like when you're done you could upload your ride to strava. The dvd I'm using now is Giro Del Mortirolo from tacx. The older tacx dvds that I have don't match reality. His are great because he recorded the gpx when he made the video so all the data agrees. You may find that making videos is a heck of a lot of work. There are some very old videos used with early versions of the older Fortius and subsequent TTS1 and TTS2 software that were more basic. Not sure what specific videos you are referring to. Those old crufty tacx videos are fine, its just all the auxiliary data isn't so great. I'd love it if someone had already done this.
Nothing bursts your bubble like seeing a steep climb but the trainer thinks youre descending.Īt this point when I want to try a new ride I must creating a gpx for the route then repair the video sync so it works for me. I don't know that it needed 21 but I put a mark at all the places where I'd care if it was out of sync. The benefit of this over a simple linear interpolate is that it retains the relative speed of the recording vehicle between the fact points.įor the tacx gavia ride I was able to bring it into sync with 21 points. I give it a set of points that I consider facts: and it interpolates all the points in the rlv so my facts become true.
I played with some route editor from cyclops for a whole day but it was hugely frustrating.įinally I just wrote a small command line program to rewrite existing rlvs distance/video mapping. I've seen references to "RLV Studio" and "RLV Workbench" but the sites seem to be gone now. What is bothering me now is that the tacx video has gaps and the 'tacx distance' doesn't map to reality which cause the videos to fall out of sync. I also added a kinetic energy model to golden cheetah so the climbs are now properly difficult.
I created a gpx for a ride by consolidating strava rides which means I can now see my route when I'm done, as if I'd ridden it with strava. The tacx rlv only have a distance/slope map and a distance/frame map, which isn't so satisfying for me. I recently was given a few old tacx dvds and thought I'd give them a go. If so can anyone point me to a better place to discuss this stuff? Seems like this is the best forum on the web for this stuff. I'm completely new to the virtual ride community.
