Make sure that each still‑image file
name contains an equal number of digits at the end and has the correct
file extension—for example, file000.bmp, file001.bmp, and so forth.
Choose File > Import.
Locate and select the first numbered
file in the sequence, select Numbered Stills, and click Open. When
Numbered Stills is selected, Adobe Premiere Pro interprets each
of the numbered files as a single frame in a video clip.
Note: Changing the default duration of still images in the
Preferences dialog box does not affect the duration of numbered
stills imported into a video clip. Each still becomes one frame
when imported in this way.
