See all Show me
Sunday morning in Rotterdam. Once again a dog tried to attack us. This time it happened in front of the camera (from 0.40). Do dogs hate trikes, or what?

No music this time. Just the sound of the city.

Some shots were done with the camera mounted on the trike, others handheld.

The photos were taken by my wife Trudy.

The movements in the original interlaced footage are fluid. Unfortunately once compressed (using vimeo guidelines for uploading) all fluidness is lost. Does anybody know how to improve this?

Edit: new upload with a bitrate of 3500.

    That doggy almost got you...
    Beautifull moving camera shots from your trike: it's a great dolly system. The ratling of the chain is great sound and doesn't ask for music support.
    On my computer movements seem to be fluid. Maybe you can lower the bitrate the remove the shakyness with slower computers.

    I passed the dog with the cam without too much trouble. But then he came very close to the one riding behind me.

    My Mac is not too slow, but still I have this stroboscopic effect. After Vimeo compression it's worse.

    I'm now rendering a new movie with a bitrate of 3500 (instead of 6000). Maybe I'll buy a new Mac and see if that helps :)

    I would render at 3000kbps if the strobe effect persists. The HD quality will remain.
    I have some strobe in the second scene when filming through the fence. That could be normal for the Vim-compression with the vertical lines at 24P.

    Next time I'll try 3000. I've just finished the 3500 kbps upload and no time left to do it all over again.

    The lower bitrate did little for me (just some more artifacts than the 6000 kbps version). But maybe on other computers it will help.

    I have been looking at your other HD vid's.
    'Cycling' is also jittery, not by the handshake, but on quick cammoves and pans in the image. Statics are good.

    And you say that the original 'interlaced' images are fluent. Is the intermediate QT h.264 version OK?

    If yes, then it must have to do with the V-compression at 24p. I know 24p and 25p is a bit jittery on pixelmovement. More tests will be necessary to find out...lol.

    Edit: when looking carefully at my bridge video, you will also see the 24p jitter.

    I see the effect in all uploaded vids with fast movement. It's characteristic for progressive video, especially when heavily compressed.

    The interlaced footage is fluent, both on the computer screen and on a tv set (even if the footage is downsized and burned on a SD DVD).

    When I compress using (very) high bitrates the quality is acceptable. Lower bitrates bring the mentioned effect.

    You're right: I will keep testing. Thanks for all the advice.

    maybe its because the trikes leave you with the same height of the dogs.
  • 2MAKEMOVIES 5 months ago
    It must be something like that. Maybe the dogs are not afraid because we seem so small.

    Next time one attacks I will ask him ...... :)

    Very nice light,I like the low angle of view!
  • 2MAKEMOVIES 5 months ago
    Yeah the light was beautifull. Well noticed.

    On a big screen the low angle shots are impressive. Gives a little bit the impression of F1 footage :)
