I recently began importing JPEGS as sequence footage into Adobe After Effects CS4 at my school. It works fine and had no problems following these steps:
Import>File Select file Format JPEG Import as Footage JPEG sequence checked.
Downloaded CS5 Installed it worked fine using the above settings. Used for 24 hours. The next day I tried to do the exact same thing and the dialogue box will not remain checked for JPEG Sequence. No matter how many different ways I try the same exact steps the dialogue box simply refuse to keep the JPEG Sequence checked. Weird thing is I was at a friend's house who has CS5 and his would not allow the JPEGS to be imported as a sequence either. This worked totally fine on my copy of CS5 for 24 hours..I changed no settings from one day to the next. Can someone with this?
