    I tried shooting at night time today and got pretty bad results. It is kind of strange, because there is more noise on the blue sky than on the darker trees. I have uploaded the videofile so you can see here:
    https://f1.creativecow.net/6156/lowlight-shoot

    Videofile information:
    Camera: Canon 7D
    Lens: Canon EF-S 55-250mm
    1920×1080 24fps, Shutter 30, ISO 200, Aperture 4.0

    Picture
    The photographs also had noise. Link to one of the photographs: https://tinypic.com/r/33b1tax/5

    Thank you.

    What I meant by picture styles was, does these affect the image quality itself? I really like the Cloudy option in setting the white balance, but this same effect can be applied in After Effects if your original shot is taken with auto white balance.

    I noticed that you turned everything all the way down without tone. I tried this, and I thought the difference was not that huge. I might just be too inexperienced to notice the differences. So far, I have the impression that you could change a shot taken with standard picture style and Auto white balance to anything of the other picture styles and white balances that are available, in After Effects later. Is this true?

    I have some experience with After Effects, so my priority first and foremost is to get the best video quality possible and least amount of grain and noise. Changing the looks, warmth, contrast, color and so on of the picture would be easier for me to do in After Effects.

    Hi again, and thank you so much for your time.

    I tried your recommendations, and it worked out very good. Thank you so much for your advice. The quality overall is great. I didn’t change the shutter speed from 1/50 and only played around with the ISO and aperture to get the right exposure, and switched to manual focus on the lenses.

    I do have some questions though, for example, why would you recommend shooting at 24fps 1080p instead of 30fps 1080p? If i shot at 30fps on 1080p, then I should set my shutter speed to 1/60, but when would I choose to shoot at 30fps instead of 24fps?

    Why I wanted to shoot in 720p at 60fps in the first palce was because of a super slow-motion effect I wanted to apply to the clip later and because the file sizes are smaller. Would you not not recommend shooting at 720p 60fps, 125 shutter speed on the entire project, instead of cropping the 1080p clips to 720p afterwards? In terms of image quality itself, there should not be any too noticeable difference between 1080 and 720p should it?

    One other thing I would like to know about, is shooting in low-light outdoors and indoors, and how much of a difference these picture styles make. I know both of these subjects are quite heavy.

    Thank you so much for your time and answer.

    I tried what you said, and I got good results. What would you recommend for low-light shooting? However, I didn’t quite understand what you meant by exposure indicator, I know what it is and I know it is below the battery icon on the information screen on top. However, it didn’t move at all even when the scene was too bright. I changed the shutter speed to decrease the over exposure.

    (My wide angle lens can’t go below 4.0 in AP.)

    Shutter speed
    One other thing I noticed was that the shutter speed stopped at 60, but could go lower if I was in a brighter environment. I didn’t know this was possible.


    Focus

    Another problem that I don’t understand is focusing. Why do I need to focus at all? What If I don’t want a shallow depth of field, but want everything in the image to be equally detailed and focused on? I know the aperture must be higher, but what then do I need the focus for?

    For example, I am highly inspired by this video and will hopefully learn to master these kinds of projects in a couple of years:
    https://vimeo.com/22439234
    I know this timelapse is made up of individual photographs and not video, but still, even in the photographs he had to focus on something? My point is that the entire image in this video is equally detailed.

    I know this all sounds incredibly noobie, and it is. I will try uploading my videos as soon as I get time and show you more precisely what I get.
