[PD] Videos don't loop smoothly on Mac
Hi, I've found out that on Mac OS, pix_film doesn't loop videos smoothly, that is, every time you jump from the last frame to the first, a little delay occurs. This doesn't happen on Linux nor Windows with the same video files, and I've never observed it on Window nor linux with _any_ video file (or maybe only with some codecs with a lot of inter-frame compression). Also, these files are coded with the Apple Animation codec which shouldn't give any such problem. Has anybody found a workaround or solution? (I guess somebody has been using video with Pd on Mac OS...) It must be a general problem with quicktime, as I've heard people using Mac have the same issue (people seem to assume it is just something you have to live with), however if I play it with the Quicktime Player it loops fine (something I wouldn't even expect from a standalone player).. Has anybody faced this problem and found a solution? (other than generating a long video wit the loop repeated a lot of times)... thanks m. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Hmm. Can't say I've noticed that but I usually recommend photo jpeg codec to ensure cross platform playback I usually use pdp-yqt Patrick Pagano B.S.,M.F.A Digital Media Engineer UF Digital Worlds Institute (352)294-2020 On Jun 23, 2011, at 12:15 PM, Matteo Sisti Sette matteosistise...@gmail.com wrote: Hi, I've found out that on Mac OS, pix_film doesn't loop videos smoothly, that is, every time you jump from the last frame to the first, a little delay occurs.

I haven't tried with auto 1, only tried by explicitly sending frame number. Even if it worked fine with auto 1 it is not an option for me. i never experienced or noticed something like that.

It's been a long time since I did it, and I don't have a mac to test on, but I recall that there are settings you can make to the file, then save, which solve this. The 'full' paid quicktime player could make and save the changes to the .mov file in the GUI, but you could also do everything through scripting. Maybe just set the file to loop automatically so that quicktime does the work for you. There was also an option to buffer some frames. It was certainly possible to loop smoothly. Sorry I can't add more detail here, but I don't use OSX much any more. Simon ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
