I have been using the blender sequence editor to edit footage from a dv camera and I have never had this problem before. Now, whenever I try to use ffmpeg to render an edited video, or whenever I try to make a mixdown blender gives me either the message “could not open file for writing” with the full render or “Can’t Open output file” when I try to do a mixdown. Normal still renders work fine as do animations that do not use ffmpeg. FFmpeg still does not work even if the option to multiplex audio is turned off.
The only change that I have made recently is installing and then uninstalling ffdshow in an effort to get virtual dub to use a greater variety of compression codecs.
I’ve already tried to reinstall blender with no luck. I really need to get this to work, otherwise its straight back to windows moviemaker for all video editing projects. Any ideas would be greatly appreciated.
I really don’t know what any of this means, but if its any help…
