Problem with importing a video

Unity Engine
1

Dear Community,

i´ve tried to import a video but there are a few problems.

First of all, the import is extremely slow. My video size is about 133mb and it took Unity nearly 6 hours to import. After that, i watched the video in unity and recognized that it was broken. There appeared many pixel errors, so i deleted it, converted it from mp4 to mov and tried it again. The same import time, the same problems. The reimport button cant fixed that problem too.

No other asset tooked that much time before and im really desperated.
Hope someone can help me!

Greetings

What platform are you building for and what kind of machine are you using with Unity?

Have you also tried any other .mp4 file to see if the problem persists?

Im using and exporting for PC under Windows 8.
mp4 file doesnt work at all (no picture but sound)
Tried it with a smaller mov file. The imports quite faster, but the same pixel errors like in the big one.

Can you try uploading either .MP4 file so that i can check if there are any problems with the file itself?

Cant post the link here, hope you recieved my private mail.
Still cant fix the problem by myself…

Thanks again!

I have this same problem with Unity 4.6.1; I can’t figure out why it’s so slow. I have a workstation with a Windows 7 64-bit running on a Rampage IV Extreme Black with a 4960x CPU, 64 GB of Corsair Dominator RAM and a PCIe SSD as the boot volume, so performance really should not be an issue.

Update:

QuicktimeTools is only using 8% of my CPU; the temperature of my cooling loop is only 23 degrees Celsius, only slightly warmer than ambient. The cores themselves are maxing out at 32, 25, 25, 41, 32 and 27 degrees respectively. In other words, I have plenty of overhead. It seems like the software is just inefficient.

Does anyone have any idea how I can optimize my videos to speed up import?

The originals I received were .mp4s. They were stuttering during playback, so I transcoded them with ffmpeg/avant-gui to .movs at 4256 kbps with h.264, and 128 kbps/44.1k hz mp3 for the audio. The video is just under 5 minutes in length. These don’t seem like crazy values to me.
