RLV (Real Life Video) HowTo

How to make your own RLV

(Pls. send me a mail with correct English, and I update the text)

A sensible resolution is 1280×720 – 25p (30p) (P-progressive not I- Interlaced)
It is an advantage if the camera can be run manually, so that one can set a fixed shutter speed of 1/500s, for example. This is to freeze out the details at the edge of the image where there is much movement.

Example of Camera:



The upper camera is a professional camera that takes good pictures and can use a fixed shutter speed. The other is a sports / action helmet camera that can also be used(NO_Tytlandsvik2). Not possible for fixed shutter speed, but since it is an action camera it has fast build in shutter speed. Both use 32GB SD card. So you can film for about 2 hours of HD quality.


My recommendation is Garmin Forerunner or Edge. You can use other GPS systems as well. It must be suitable to add GPS to log in once a second. You must have the ability to edit the track, and you must be able to save as gpx file. And remember you need good quality GPS tracks.



GPS is set to log with 1s interval. Not smart logging.

Garmin included software. Download here.
RLV-Studio: (need login for download)
Virtual Dub:
Sony Vegas Pro – or other video editing program
Xvid codek:  download

BaseCamp (for cutting GPS tracks)
Logarith losless codek:
Deshaker til Virtual Dub:
Rlv-patch: (needed to place avi’s on another location)

Installation of equipment:
Mount the camera equipment so that it is most possible in one with the car. It creates the least vibration. Make sure that both pan and tilt is correct and provides natural cycle view when it is played.

GPS mounted on the roof of the car with the antenna with the best possible sky view. Let be on for 10 min with no car movement in good satellite conditions for calibration. You depend on the quality of gps track.

Place the camera in the normal head height as a cyclist. When you attach it to the vehicle remember the position, for example over the passenger seat. When you drive, and record, it is important that the camera goes where it had been natural to ride a bike. It is most natural. Make sure you get the right exposure. Please start to shoot 200-300m in front of a bridge/river/junctions or something that is easy to recognize on the map. You do not need to start recording at the start point of the film. Start recording before and have a normal cycling speed at the starting point.

Drive speed when recording
Run as near the real cycling speed as possible. Max 10% faster. Be careful especially on uphill. Remember that downhill, you have 40+ km/h on trainer. This could mean that you must have great speed on the car in tight corners / roundabouts and the like. It may be sensible to have a poster on the back of the car telling people behind that there is video recording in progress. They then understand why you running so slowly.
If you are new and not experienced, it will be a great advantage to drive the entire trip without stopping. Add route out traffic lights and the like. If you have to stop somewhere, there will actually be easier to cancel the trip and restart. If you are going to cut together several recordings and have many stops you can not use this HowTo’en. Then RLV must be made  in a different and more sophisticated way.

Preparing the film:

GPS Track
Load the track into the Garmin program. Find a starting point that is easy to recognize in the movie. For example, a bridge. In the GPS track find the end point where you want to stop the movie. It is important to find the starting point again in the movie. When the track has the desired length, save the track as a gpx file.

Start the RLV-Studio and load the gpx-file:


Use the settings above. Use 30fps if your camera records 30fps


Then go to the Create Files RLV-studio. Enter the RLV name. Use country code at the beginning of the filename. NO_(Norway)



Hit Create PGMF and Create RLV. In the RLV-studio Created files dir there is also a cut directory. Open that file.



Your file should look like the one above. From start to finish in one sequence. Without stop. Load the video file into video editing program. Find the exact starting point. Cut the film here. Go to “Remove from frame” and cut the film here. Now you have the correct length of your movie. Save your movie with lossless codec. The file prodused is large, but it is without loss of quality. Load the video in VirtualDub and run Deshaker. (google to figure out how to use deshaker) Use the settings below pass 2. Use the default pass 1


When deshaker is finished. Save again with Logarith lossless codec. You now have a video that is deshaked with full quality. Load that avi back into the video editing program. Make any adjustments to the color / contrast. Add text or other things you want to include in the video. Export the movie, use Xvid 10000kbps. You now have the movie and managing(rlv, pgmf) files. Install into Tacx Fortius, bike the track and carefully notice any altitude error. Load gpx file into 3D Route Builder. Select the problem start and end of problem. Right-click altitude smooth. Make the changes which is needed. Produce as new rlv and pgmf files in RLV studio. Ride again, new notes. Into 3D rout builder, change, then to the RLV studio, producing new pgmf and rlv. Until you are satisfied.

Congratulations, you’ve created your first rlv!

    Hi all,

    I am new to the RLV world, and I would like to create my first RLV video.
    I am still in th testing phase, and I encounter the followin problem:
    I made a short video (HD, 30 fps) of less than 1 minute, just to test how it works,
    and my first task is to set the rlv, pmgf and avi files to the same length. For example
    I want to remove the first and last frames. Following the instructions, I expect
    that after creating the rlv and pgmf files with rlv studio, in the cut file I find
    the number of frames of the movie, so I can then edit the video file and select the
    same number of frames, by cutting where it is necessary. However for 32 seconds
    of recording I get round 900 frames in the video, which is consistent with 30 fps, but
    many more in the cut file of rlv-studio. Now, my simple naive question is: where can I find or how can I calculate the real number of frames to cut the video file?
    Thanks to anybody for the help.

    This might be a bit late but here goes. The .rlv file that RLVStudio makes links the frames in your video to how far you have travelled on the trainer. If RLVStudio is saying that your video has a different number of frames to what it actually has then your RLV will be out of sync.

    The first thing I would check is how many frames per second your video really is. As I understand it, 30fps is actually 29.97fps. The problem arises because RLVStudio only works with integer frame rates, ie. 29fps or 30fps. So you either need to reencode the video or adjust the time stamps of your GPX data (reencoding to an integer frame rate is much easier).

    The second thing I would check is whether you have correctly calculated the sync of the video and the GPX data.

    In short, your RLV will only be in sync if you cut the video where RLVStudio tells you and that these cuts are in the right place.

    Good luck…

    Thanks Adam.

    In the end I started using RLV workbench, that gives me the possibility to adjust
    the speed or the time span between points by hand. So in the end as first I cut
    the video in the way I like (not only following the suggestions of the RlV studio),
    and then I synchronize with RLV-workbench, according the the video.

    Reults look promising anf I am almost done with my first RLV, which I hope it will soon appear here.



    J’ai 1 Racer s Kettler et je voudrais faire des Rlv avec video moi-même;
    J’arrive à faire des fichiers GPX mais je ne comprend comment intégrer la vidéo dans le fichier.
    Pouvez-vous m’aider et m’expliquer comment on réalise l’ensemble pour avoir une vidéo qui tourne avec Kettler World Tours.
    Merci d’avance.
