    Default DSL shooting issue

    Hey guys, new here!!! Excited to meet a group of people that shares the same hobby. (Some of you might even be profession)!

    I am a decent video editor but my weaknesses come from using the camera to film.

    Here is a video: You will see the image is terrible, any idead of what it could be?

    http://www.youtube.com/watch?v=mtaPA...ature=youtu.be filmed at 720p 60 fps Just look at the shirt or anything that has lines in general.

    Thanks a lot guys!You rock!

    That looks like a combination of noise, bad codec compression and moiré. The coloured moving pattern is called moiré and is a result of fine lines in the material being sampled (and down scaled) differently as it shifts across the sensor.

    What camera did you use for the 720/60p? Nikon & earlier Canon DSLRs were well know for this problem and shooting at 720p instead of 1080p made it even worse!

    David, I used a 600d yeah. I have to shoot in 720p as I shoot a lot of action sports with high movement and 1080p only allows me to go 30fps.

    Thanks for the quick reply I will look into a fix for it.

    Thanks!

    There is no 'fix' for this problem on a crop sensor DSLR as far as I know.

    Mosaic Engineering made a filter for the 5D2 that fit over the sensor but I don't think they ever make one for the crop cameras.

    The best you can hope for is to reduce the in-camera sharpening to minimum, reduce the contrast by a couple of notches and see what happens. You'll need to re-adjust the colours and sharpening in editing, but hopefully that's not too much of a problem for you.

    DSLRs, even at 720/60p are not really ideal for shooting sports. Proper video cameras (e.g. the HF-G30 etc) which can do 1080/60p are a better solution.

    For the moiré issue try shooting a little bit soft (in the camera settings, not focus) then sharpen the image in post, it seems to help with my Nikon.
