I just rendered a large file (1:15 hrs). When done I do to the folder and all I see is the .tmp file. Did a search on my computer and can't find it. Do I really have to render (about 10-12 hours) all over again ?
To which codec did you render? DNxHD for example will create a temp file; once the render is finished it will convert it to a .mov file and depending on size and your system it can take a long to do so or even fail. Try renaming the .tmp file to the extension you need.
