Re: [CinCVS] still pictures out of a video
Thanks, Joe. Is it clever to try to take a nice and sharp still picture out of an interlaced video? :-/ transcode has worked for me in the past what about the quality of your still pictures?

Re: [CinCVS] still pictures out of a video
Ciao Joe! I guess just try it and judge it for your needs :-) Well,... I tried to take a single frame out of my video (rendering a single frame, with freeze frame effect, with loop effect set on one frame only) but anyway I judge the quality of the picture much lower than the quality of the video (sharpness especially). Too low. I only suspect it being caused by interlace. So I'm going to have a desperate cry for half a minute and to grieve over the loss of stills in my poor video for the other half of the minute. Unless I'm missing something...

Hey hey! On 2/11/07, Raffaella Traniello [EMAIL PROTECTED] wrote: Unless I'm missing something... Hmmm, mplayer offers a few filters for working with interlaced video. If the ones in cinelerra didn't work, you may want to try those. mplayer video.avi -vo png -vf pp=fd There are heaps of post-processing (pp) filters that deinterlace. From man mplayer: lb/linblenddeint Linear blend deinterlacing filter that dein- terlaces the given block by filtering all lines with a (1 2 1) filter. li/linipoldeint Linear interpolating deinterlacing filter that deinterlaces the given block by linear- ly interpolating every second line. ci/cubicipoldeint Cubic interpolating deinterlacing filter deinterlaces the given block by cubically interpolating every second line. md/mediandeint Median deinterlacing filter that deinter- laces the given block by applying a median filter to every second line. fd/ffmpegdeint FFmpeg deinterlacing filter that deinter- laces the given block by filtering every second line with a (-1 4 2 4 -1) filter. l5/lowpass5 Vertically applied FIR lowpass deinterlacing filter that deinterlaces the given block by filtering all lines with a (-1 2 6 2 -1) filter.

Re: [CinCVS] still pictures out of a video
a) you don't need to do freeze frame, just render only one frame to jpg b) you have plugin to do deinterlace... use it bye andraz On Sun, 2007-02-11 at 18:38 +0100, Raffaella Traniello wrote: Ciao Joe!

Re: [CinCVS] still pictures out of a video
Thanks Andraz, thanks Joe. Eventually I've found my way out of the labyrinth of the countless Cinelerra deinterlace option combinations. My still pictures are clearer. My mind is too. So it seems that instead of a minute of deep sorrow I'm going to have a minute of great happiness. :-) Ciao Raffaella ___ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
