I am not sure what is happening? I have made a time-lapse of jpeg files from Lightroom and added a music file to the time-lapse, but when i go to render it after putting in desired settings I am constantly getting (Could not complete your request because the file name was not valid.). I am not sur show to change the file name or even where to find it. i am a newish user of Photoshop so this has me stumped, any help would be appreciated.
Without any info about your system, your version of PS, exact settings, files used, storage locations etc. nobody can tell you much. Sorry, but your post is way to vague and generic to be of any use.
