Happy Bokeh Friday

some Hamburg Flickr people There is a nice tradition of showing a bokeh image every Friday.

Now I thought I would use the possibilities of the D7000 and create a bokeh film. I was then able to test how the really old AI-S 35mm f/1.4 performs in video mode. This lens does not have autofocus, but has 9 aperture blades for particularly beautiful blurring.

Speaking of film: mine Kickboxing film was discussed quite critically in many discussion forums. I was able to learn a lot from the contributions. Filming is different than taking photos. I find it very useful to now have a camera with which I can use both media. There are stories that can be told better with a picture - and stories that work better as a film.

I'm slowly getting closer to the requirements of films. There's just one point where I'm still not making any progress - and I hope you can help me with that. In the bokeh film you can still see a slight jerking in the moving elements - especially the cars. In my opinion this is due to the encoding of the film, because the jerking is not visible in the original. Even after editing, no jerking can be seen in the Quicktime movie. Only when I encode the film for vimeo does the jerking occur. That makes perfect sense to me. After all, the original as a Quicktime movie has almost 500MB and on vimeo it only has a good 30MB. But which settings do I have to choose when exporting the film so that the jerking is no longer visible on Vimeo? If you have any tips for me, I would be really grateful if you would share them with me.

  1. Hello Stefan, very cool film, cool shots! The reflection in particular is really amazing.

    Regarding the jerking: in the last fade-out I think I can see that the film was coded interlaced. That would of course be fatal. You have 1080p (p for progressive) material that you should then output exactly as 1080p24 in the encoding.

    VLG,

  3. A really great film. I really like the colors. The jerking, well, I don't think it's that tragic, but there are certainly enough experts here who can help you.

  4. Very nice shots with the D7000.

    Yes, I have the jerking on my D90 too. So far I haven't been able to find a solution for this. I noticed it extremely when I was driving my self-made camera dolly.

    Is the number of images per second when exporting the same as the original?

    Greetings Henning

    ps: If you would like to see the video that was made with the D90, just look here :-). (http://www.henning-witzel.de/video/campusleben)

    1. @Henning Witzel, nice video with the D90 - of course I watched it straight away.
      I now also think that it is the number of images that is responsible for the jerking. I've been playing around with mpeg Streamclip, but I still need a few tests before I have a solution...
