Why can I no longer export in H.264 and .mov when I work in Adobe Premiere Pro CS6? I had the option to export in .mov last week and now it is just gone. It doesn't show up on the list of exporting options. What happened? How do I fix this and get those exporting options back? What is making this occur? How can it be fixed?
Have you installed any new codec's?
I haven't installed new codecs I don't believe but I have installed new stuff to my computer outside of Premiere Pro
Windows or Mac?
Check the codec folder in PPro programs to see if the codecs are actually present.
If on windows, run a disk check to recover any possible corrupt files, (it's happened to me before with files that mysteriously disappear). If still no luck, then restore your PC using a recovery point to before you installed that additional software and see if that clears it up.
