weird effect on hair rendering

Hi,

Sorry for my bad english, it's not my native langage.

I start with daz and I have a strange problem with rendering.

the hair is more swollen in animation than in the picture yet these are the same images used in the video.

First image is the last picture of my animation when I play it, the second is a transition picture after the animation. it's the same image as the one used in the animation, but the rendering of the hair is not the same.
the animation is encoded in webm format with Shotcut.

If anyone can help me solve this problem, I thank them in advance.

    Looks like the eyebrows rise to so it might be a morph that is being added during the length of the animation which is also affecting the hair. Another thought is it might be a Dforce simulation running on the hair.

    thank you for your quick reply, it's not a morphing problem, it's normal for the eyebrows to rise, there are 3 extra frames in the animation but I wasn't able to take exactly the right screen.
    On the other hand, it's quite possible that this is due to the Dforce simulation, which I ran before making the animation.
    I'll do a little test to see if it's really coming from there. I'll keep you posted and thank you very much.

     

    Edit:I've just done a test on a new scene with just a movement of the arms but I have the same problem.

    Webm is an format that compresses the file so I am wondering if it is compressing each image as it renders it to video so losing some of the stray hair that is in the first image.

    In fact it's the other way round, I'm having trouble expressing myself (bad English) image 1 is the one in the video.
    The video is perfect, it's when I use the same image as a picture that I have this problem.

    Basically, when I look at my renders, they're like my 2nd picture, but when I encode my video, the video is like picture 1. And if I use them as a simple series of images, they're like my 2nd image.
    it's crazy !

    But thanks for trying to help.

    Hi,

    I've figured out how to avoid this problem, even if it doesn't suit me.
    I have to render my animation in jpg instead of png.
