Pump It Up 1st to 3rd intro FMVs (*.ANI and *.DAT)

[latent bear]

Hi everyone. I'm looking to rip the files from the MK3-era Pump It Up arcade games (1st Dance Floor to The Prex 3), but for now I'm focusing on the intro movies that play during the demo loops of the first three PIU arcade games. The first two games have the opening in the .ANI format, while the third game (O.B.G) has the file in the .DAT format. Opening up HxD (or any hex editor for that matter) reveals that these files have a "PTX" header every few bytes or do; perhaps they make up the frames? Regardless, how can I go about ripping the frames from these files and by and large converting the .PTX files to a readable image format like .PNG? Thanks in advance.

Below are what the introduction FMVs look like:

ADDENDUM: The ANI files used in the first two games seem to be Andamiro's proprietary video format that stores the PTX frames. They are not the usual "animated cursor" files used by Windows. The INTRO.DAT file in the O.B.G also stores the PTX frames in a similar fashion. The PTX format itself may have also been Andamiro's proprietary image format. The way the intro videos are presented in the game may indicate that the resolution of the PTX frames are way smaller than the 640x480 resolution these games run at, so the files may have been scaled in a way that it looks as if a scanline filter was applied over the video.
