TT: used your scripts and all now seems to be okay. It was nothing obvious but seems to have been a script left over from my 3D mouse: it kept looking for a central rotation point. It kept repeating it over and over in the ruby console.
Many thanks - sure hope that problem is really gone. Been staying steady at 451/1000.
Thank you a lot, Chris. π π Worked perfectly. All my cameras (actually, scenes as you pointed out) are perspective ones, so I received no warnings.
No worries about not being able to undo... I save a new file version several times a day.
Good quality comes with long render times, and there is nothing you can do about it in any program you use. I would suggest you to convert the avi file to a different format to compres it, like MPEG-4 to get the best quality with the lowest bitrate. Just google for "avi to MPEG-4 converter" and you should get loads of options. Experiment what quality you can get under those 5mb. Also I would suggest you to do some reading about this topic to better understand how all of it works to get the best results.
Windows has done that since XP. Zip files act as regular folders. To zip a file (or files) you just select them, right-click, Send To > Compressed (Zipped) Archive
