I've been using MC5.5 on my current computer and everything's been smooth and easy, however upon upgrading to MC6 import times have shot from anywhere between 5 hours to 15 hours.

I have gone to past projects and tried re-importing footage (to the same project/settings) that once took 10minutes-an hour, now it takes 6 hours+ which is why I've narrowed it down to either MC6 or my Avid settings (which I have also checked thoroughly and everything seems fine).

I guess my question is what can I try from here? Is anyone else having/had this issue before?

My PC is above and beyond the necessary hardware required to run Avid MC6, this shouldn't be an issue. Sorry if I'm missing necessary information, it's my first time using these forums. I have found one or two others with this issue around the net on past versions of MC but no answers.

Hi,

Importing what kind of footage (format/frame rate) into what kind of project?

ciao,
Carl 

Hrm, it seems to just be .mp4 formats since I've been importing them a lot recently, though I was importing the same files fine on MC5.5...

For example:

Project:

Type: 25p PAL, Aspect: 16:9, Colour Space: YCbCr 601, Raster: 720x576

File: 720x576, 25p, mp4,

 

I've tried pretty much all import formats/import res settings.

 

 

If they're .mp4, I'd bet they are H.264 and RGB.  That doesn't account for the time you're seeing, but it will affect the look of them after they are imported.

When you open them with QT player hit CTRL+I and tell us what info it gives you.

What version QT do you have installed?

Quicktime:
Version 7.7.1 (1680.42)

QT says the file is 25fps, 1024x576. Different from its 'properties' tab.

What happens if you first ama link them and then transcode them ?

The whole program freezes up and runs extremely slowly, I can do other things but MC does nothing for a minute. Then when I try running through the file in Avid it varies from slightly choppy to freezing up.

So much that I can't transcode them.

Again, my computer runs Avid fine with other files (including HD).

I have seen that in some .mp4 files downloaded from Internet.

I convert those files to Avid DV codec using TMPGEnc and they import by fast import then.

Sounds like it may be what I'm looking for though it doesn't really explain why it worked fine on MC5.5, I've got some stuff to do today but I'll try it out tonight.

Thank you all very much!

I am seeing this at MC 5.5.3.1 though.

I converted to DNxHD using MPeg Streamclip which resulted in a 300gb file (the file is roughly two hours long, original file 3.5gb). I can now use AMA to edit the file but obviously it still takes forever to import. Is this sort of file size normal?

This doesn't sound right at all.

What is the original source?

And what the file produced?

DNxHD but what resolution.

Hi Stephen, the lines above do not help very much for helping You out, You'd be better off clearly listing Your hardware and software configuration; the fact that Your system ran MC 5.5 well doen't mean that it would run MC 6 as well: the new 64bit code allows for more data to be managed, but this may put an underpowered system on its knees as it will also require more computing power. Sorry for potentially being the bearer of bad news, Luca

You have a 2 hr long QT file that is only 3.5GB?  I'm really interested to know what codec was used!
