I have the same thing in preview but not in a rendered version I don't think. I am doing a video now so will render and see. Doug On 11/15/2011 07:03 PM, Ichthyostega wrote: Am 15.11.2011 18:12, schrieb Francisco López: I have a problem when I zoom in or out still ima

The only one solution that I've found to this issue is to resize the images until 2000px (width), so the value used in Camera Z is lower and the problem is imperceptible. Hope this helps someone. Thanks all of you. El 15/11/11 19:54, Francisco López escribió: I've downloaded some photos from

I've downloaded some photos from internet and the issue is seems to dissapears (or it's too low to see it). I don't know what difference can be between my photos and the ones of internet... just the resolution (200 vs 72) El 15/11/11 19:24, Francisco López escribió: The rendered video is not

The rendered video is not interlaced and I'm displaying it on my own PC (Ubuntu 11.04). I don't know if a PC it's a interlaced device or not (I think not). I'll test to interlace the rendered video and I'll post the results. Thanks. El 15/11/11 19:03, Sean M. Pappalardo escribió: On 11/15/

I already use YUV4MPEG and pipe to ffmpeg to convert to DVD format. Anyway, I tested to render without pipe and the problem doesn't dissapear. Can I attach a video example in this maling list? El 15/11/11 18:47, Michal Fapso escribió: Maybe the problem is in your rendering settings. Try to ren

Maybe the problem is in your rendering settings. Try to render to "YUV4MPEG stream" and pipe the output to ffmpeg where you can encode it with any codec. Rendering directly to quicktime + MPEG4 caused artifacts in my case. Your pictures' resolution seems to be ok. On 15 November 2011 18:37, Franci

Hi Michal. Thanks for your quick reponse and for the OpenGL trick. I use camera's Z value and my pictures are about 1056x792 for 720x576 frame size. The shaky effect appears on rendered video. Can the images' resolution be the problem? I think most of my pictures are 72x72ppp. El 15/11/11 1

Hi Francisco, I use still image zooming in Cinelerra without such problem. How exactly do you zoom? You can apply zoom effect or set Z for projector or camera. I zoom by changing camera's Z value. My pictures are 5184x3456 for 1920x1080 frame size or 640x360 for 640x360 frame size. You should nev

Hi all. I have a problem when I zoom in or out still images in Cienelerra. I get an ugly shaking effect that I don't know how to avoid. I think that this happens only when the image size is greater than the frame size. Any ideas? Thanks and I'm sorry for my english. __
