So 8 bit would have a resolution of 1/255, 16 bit of 1/65535 etc. All operations can be done with 4 byte integer math. Multiplying cannot cause overflows this way. Easy resolution change, too. Lookup-tables can be used if necessary - a near impossibility with floats. Possibly great speadups as integer ops can be executed in parallel, either in the CPU or the GPU. Just an idea.

Re: [CinCV] Cinelerra Build for Ubuntu 12.10
Eric: Thanks for your help. I was fionally successful. Here is whgat I wound up doing, in case anyone else stumbles down this path behind me :) I went back and uninstalled the deb package that I had build for x264. Then i also unistalled the deb package that I had built for ffmpeg. here is the url i had used to make the newest and most wonderful ffmpeg: http://ffmpeg.org/trac/ffmpeg/wiki/UbuntuCompilationGuide so anyway after removing those two home made .deb packages i went and dis a sudo apt get for x264 and libx264-dev Then i rebuild my ffmpeg deb package using the standard distribution x264 Then I wen tbakc and in clienelrra I did the ./autogen.sh ./configure --with-buildinfo=git/recompile --enable-mmx --without-pic make sudo make install as per Raffa's Granma instructions (they work for grandpa too) and it all went ok and now I have a working cinelerra on my Ubuntu 12.10 system Thanks again for your assistance and pointing me in the right direction I an a happy Vidiot today! -- Ubuntu-Head Tom Judge Ubuntu Head Look for us on the web: http://learnubuntu.org http://youtube.com/learnubuntunow http://twitter.com/#!/learnubuntu http://facebook.com/tvjudge Skype user learnubu...@skype.com Ubuntu-Head Tom Judge Ubuntu Head Look for us on the web: http://learnubuntu.org http://youtube.com/learnubuntunow http://twitter.com/#!/learnubuntu http://facebook.com/tvjudge Skype user learnubu...@skype.com On Tue, 2012-11-06 at 15:27 -0500, Tom Judge wrote: > ok I did that and it seemed to install but when i try to run cinelerra I get > this error > > cinelerra: error while loading shared libraries: libquicktimehv-1.6.0.so.1: > cannot open shared object file: No such file or directory > > i could not locate that package should I just try a rebuild > ___ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra

As of 8 bit colospaces there is native clamping to 0..255. My question are: what should happen if a result of an effect is out of allowed 0..1. Should every plugin clamp its result? What should happnen with possible results such as INF and NaN? Einar ___ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
RE: [CinCV] Cinelerra vs Cinelerra-CV
Dear All, I finally migrated cinelerra's builds to use the new name "cinelerra-cv". The name change will affect all the related libraries. The new builds are available in the main PPA: https://launchpad.net/~cinelerra-ppa/+archive/ppa If you have been using such PPA, I recommend installing the cinelerra-cv package. This will remove the old series (cinelerra) and install the new one. It goes without saying that the older cinelerra builds are no longer available nor maintained. Raffaella, would you please add a line in the webpage stating how to install cinelerra, once the the PPA has been enabled? sudo apt-get install cinelerra-cv Please let me know if you find any issue. Thanks.
