you can record this as a time lapse. If you are recording in PAL you’ll need 750 frames to make 30 secs, so set up your camera, then every 24 secs capture a single picture to your hard drive (every 20 secs if you are recording in NTSC). After that, import it into premiere as an image sequence. If you have a copy of premiere 6, you can capture to images straight through premiere, but I don’t believe you can capture from a dv camera as a still in premiere pro. It might be a bit of work to capture like that, so I’d suggest you get valiscam from https://www.valissoft.com/ You can set it to capture per 24 or 20 secs, and it will automatically save the pictures for you, and it’s only $5. It’s designed for webcams, but it can take dv cams and resolution. Set up your camera, make sure autofocus and auto iris and any other settings like that are turned off, set the picture quality to high, then click on start time lapse, make sure you don’t touch the camera and check on it in 5 hours. The pictures might need some deinterlacing, but with a lava lamp, it should be fine. Each pic should be about 1MB, so probably unger 1GB total. good luck
