... well, if you have to "animate" a 1000 km track with a resolution of ONE POINT every 1000 m ... this makes something like ONE THOUSAND lines to edit!! ... not to bad
It's a very easy file to write a trivial program to do the "additions" automatically - reading in a text file looking for certain entries. each "point" starts with a "<trkpt" and ends with a </trkpt>...
Thank you, that saved me from making a less informed response.

RELIVE DOES IT but as I said above you must feed it with a "real" track recording and not just with an "artificial" generated gpx file (like the one that you can gety from basecamp/ridewithgps/openrunner/etc.
You can definitely do this with GPX Animator as I've just tried it out with a gpx from RideWithGPS. You have to use the "Forced Point Time Interval Option" which I set to 10 minutes for a ride of 100 miles, although other values didn't seem to make any difference to the final video.
Documentation for GPX animator is poor at present but the app is superb and in the UK I can (legally) incorporate Ordnance Survey maps and OSM maps using official API keys (which are free) and change the zoom level of the overall trail. Well worth the effort to get to grips with it.

I had a play using Google Earth to animate a gpx track and it can be quite pretty except it really highlights altitude issues. I even tried removing the altitude from the gpx and letting Google Earth tie the track to ground but that must be interpolation based so sometimes still flying above ground level then ducking below ground level. So works best on flat and level rides.
It seems very interesting, I'm trying to register but something for some reason is going wrong!!
Do you know whether it's possible to download an mp4 or anything alike?

.. thank you, maybe the "go-premium" version can do the mp4 straightforward!!
I have paid for premium access (well worth buying) but I can't see any way of downloading an animation. There are options to download as various image formats but nothing animated that I can see.
FWIW, using the Plotaroute animation & using an Android phone app called Screen Recorder, here is a Twitter link to a route animation I recorded as an MP4 on my phone. Works ok I think. https://twitter.com/geomannie531/status ... 58594?s=19
