Importing 24fps Quicktimes Into 23.976 Projects

Here’s a neat little console command to tell Avid to ignore the frame rate of any imported Quicktime. You would need this command if, for example, you’re cutting in 23.976 but your vfx house insists on delivering 24.000 fps QTs. This would also work in the reverse, if someone delivers you 23.976fps Quicktimes and you need them to be 24.000fps.

Open the console and type in this command:

ignoreqtrate true

To turn it off, just substitute ‘false’ for ‘true’.

This works particularly well in the 24/23.976 situation since there are actually the same number of frames in both types of Quicktimes, they just play at slightly different speeds. So by telling Avid to ignore the frame rate of the Quicktime, you can prevent Avid from trying to interpolate frames to convert 23.98 to 24, since it shouldn’t be doing that anyway.

  1. I recently came across this posting and I got really excited to see that there might be a way around having to create an ale for the qt import.

    Should this be working under 3.1.2?

    I assume that you change the setting before you import. When I do so my 24fps qt still doesn’t import properly into my 23.976fps project.

    Do you have any ideas what I might be doing wrong?

    Thank you for taking your time to discuss this.

  2. I’m not sure the particulars of your problem, but the only thing that this console command does is to tell Avid to take one frame of the Quicktime (at whatever frame rate your Quicktime is) and make that one frame in your current project. If there are other conversions that would need to happen, this command won’t take care of that. All it really does is just prevent Avid from thinking it has to do some kind of frame rate conversion to bring a 24fps QT to 23.976 or vice versa.

    I’m not sure how long the command has been around, but I started using it on 2.7.2 and am currently using it on 3.1.2.

  3. Thank you for you posting this. It’s very helpful. I see you posted this back in 2009 so it’s nice to see how much it helped me in 2013. 🙂

    I work in an animation company. My Avid project settings need to be 23.98 but the animators give me shots in 24. Before I used your tip I discovered all the shots were being imported one frame less. It’s was really annoying. After using your tip I happily discovered all the shots came in the correct length.

    One thing I notice though, Avid loves reminding me that I made this change in the Console. With every shot with audio I import it pops up a warning and I’m forced to click OK before I can continue. This wouldn’t be a huge deal if it weren’t for the number of shots I bring in on a daily basis. Sometimes in the 100s. Do you know of anyway of bypassing this warning?

    Thanks again,

  4. Hey Kenn-

    I’ve noticed this too, and I haven’t found a workaround unfortunately. Avid seems to have a few of these prompts that need an OK To All option.

  5. It only happens when there’s audio embedded in the QT clip. A workaround is so stripe the audio off, then import. This, in itself, is a tedious process and could cause additional issues.

    Thanks for your help!

  6. Ha, well right, I was assuming you wanted the audio attached to your clip. Thankfully for us our vfx shots always come in mute, so I only run into this when I set the command and then import something that isn’t from vfx

    Maybe check out digital rebellions’ tools. He might have a way to remove audio in batch

  7. My animators embed the audio although I don’t need it. My Avid timeline has the real audio. Thanks for the tip, I’ll look for that software.
