Re: [PD] pix_film and readsf not in sync....
we had three different videos 4 to 6 mins length. Format was mpeg video, and the audio was standard 44100 16 bits. The video rate was 29.97 and yes I think this was the problem I finally solved it using line to ramp the number of frames+1 in the time duration of the video. Unfortunately my solution came too late to use it in the exhibition, and I did not have wireless connection at the place I was so I could not read this until today, that would have solved lot of trouble and stress ... thanks anyway, On 8 March 2012 18:59, IOhannes m zmoelnig zmoel...@iem.at wrote: -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 On 2012-03-08 17:44, tim vets wrote: [step]? from maxlib iirc: step :: output sequence of numbers (similar to 'line') sorry, I forgot one thing, it takes a list of 3 values, the third one being step (which would be 1 here oh, you mean [int]? fgmasdr IOhannes -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk9Y84wACgkQkX2Xpv6ydvTVHQCg99lFkjkuEDsuE9ZYL3SYkFZw 7Z4AoNd1frKcVID/6hXS7aXoyB5AlzAA =uL1p -END PGP SIGNATURE- ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] pix_film and readsf not in sync....
For synced playback of video and audio, you might try my 'framesync' library. Its a bit raw, but the core playback stuff works well, and I've used it in a few projects: http://puredata.info/downloads/framesync .hc On Mar 9, 2012, at 5:08 PM, altern wrote: we had three different videos 4 to 6 mins length.

Re: [PD] pix_film and readsf not in sync....
Could it be possible that your soundfile is being played back with the wrong samplerate? Like 48k instead of 44.1k?

This is ok for a while but after some time they go out of sync. The sound goes faster than the video. Any simple solution to this? or do I need to construct my own system to play the video passing the frame number to the pix_film? maybe using a line object with the total num of frames and the total time length of the video ... thanks enrike ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] pix_film and readsf not in sync....
Hi, I think I would try it this way: generate frame numbers instead of using auto. [0, m n( | [step] | where m is the number of frames in the video, and n is the number of sample frames in the audio file, divided by 44.1 (or your samplerate) gr, Tim 2012/3/8 altern alte...@gmail.com hi I am reading a video with pix_film and trigger it using auto, at the same time load a sound file with readsf ~ .

Re: [PD] pix_film and readsf not in sync....
depending on the length of the audio/video there might be different techniques. how long is your clip? have you looked at those examples? http://www.uni-weimar.de/medien/wiki/Audiovideo m.
