Im trying to import videos into my project, every time i try to do it a little popup comes up that says quicktime tools.exe has stopped working and then tells me to close it. I read somewhere that installing quicktime while unity is open can be the problem, and uninstalling, then reinstalling when it is closed will fix it. It did not whatsoever. I know ive seen games and apps from unity that use movietextures so i know this is possible. Ive tried it with all of the different compatible file types, i get the same result every single time. They are not big files and they play in quicktime just fine if i just double click the file. I cannot find any information anywhere on how to fix this as i dont think people use movietextures in unity too often. HAS ANYBODY SUCCESFULLY IMPORTED VIDEOS IN THEIR PROJECT??? im using unity 5 free btw and windows 10 (i was getting this same error on windows 8.1 as well).
If the QuickTime plugin walks on your nerve, Read this
Don’t use it anymore, Simply use this application to convert your videos to OGV (with any quality you’d like) and just copy and paste the new OGV file in your Unity3D folder:

I literally hate the QuickTime plugin, It better stay away from me (: 
.
File types didn’t have any effect for me. MP4 files behaved the same as MOV files.
Spent a long time banging my head against this issue. Here’s what worked for me:
-
WAIT 10+ MINUTES. When importing my files, Unity became busy and “not responding.” I thought something was going wrong, but it’s just doing a lot of work to import the video. So just sit back for a bunch of minutes and see if it works. The longer the video, the longer your wait.
- If you’re getting the error “QuicktimeTools.exe has stopped working,” it’s because you have two instances of the EXE running. Open Task Manager, find the Background Process called QuicktimeTools.exe and delete it. Then try importing your asset.
- There are two ways to import assets into Unity. You can click and drag a file from outside your project folder into your Unity window, or you can manage your file system directly by moving a file from outside your folder into your Assets folder. If you’re only trying one approach, maybe it’ll help to try the other approach?
Hope this helps!
FIGURED IT OUT, need to run unity as administrator. dont know why but it works now

Videos need to be a specfic format for unity to be able to bring them in.
.mov files work great. If its not a /mov file i would suggest converting it.
There are a few other types it can import, but i find it degrades the video quality.
once done, it will take a while to import depending on size of video. a 30 second video can take a good 5 mins.
Hey @Krides for me it didn’t work to run Unity as administrator but manually running the conversion tool from command line did the trick as described here Converting videos to .ogg manually with QuicktimeTools.exe « Unity Coding – Unity3D
To others running into this problem on later Unity versions the “Movie Texture” import version had been deprecated.
By default a mp4 that is imported is set to be a VideoClip import version.
The VideoClip can’t be dragged on the material like the “Movie Texture” can. Instead you need to add a “Video Player” component onto the object containing the mesh that you want to play the video on.
Hopefully this will save others headaches of trying to figure out why the movie can’t be used with the material.
