MOV files and save for web legacy not working

[Danielle39]

MOV files do not appear in photoshop, there is a checked box once imported? This feature used to work but not sure if it is a MAC or adobe update.
when using the 'save for web legacy' feature, photoshop will crash or when this does load, it shows a red/pink square. I cannot use this feature to create animated GIFs. 
Can anyone reccomend an alternative or ways to fix this?

Convert your .mov file to .mp4 first:

• Adobe Media Encoder

• Adobe Express (online)

its an animation file and changing this to mp4, then trying to use save for web there is more noise present and distortion on the final GIF output
