Hi everyone,

 

   So I was having trouble with laggy video playback so after clicking around through forums, I discovered that it was due to the fact the my voice-overs were recorded in 44.1khz as opposed to 48khz, which is what the rest of my audio is.

 

I was happy to discover the solution to my problem, but now have another to solve. I will record my future voice-overs in 48khz but I already have a good deal done in 44.1khz and need to convert them (hours of voice-over work done there).

 

Sooooooo.....

 

What is the best way to convert 44.1khz audio to 48khz?

 

I am currently sending the files to compressor, converting them to AIFF 48khz 16-bit, and then re-importing them into my timeline. This process is very time-consuming, especially due to the hundreds of files I must convert.

 

Is there an easier/more streamlined methd of converting 44.1khz files into 48khz files?

 

 

I hope someone knows the answer to this and maybe will solve others' questions about why their video is so laggy.

    If your sequence settings are set for 48khz, then all you need to do is render the non-48khz audio as you have placed it in your sequence/timeline.

     

    Make sure your render options are checked to include rendering audio (I usually turn all rendering options on):

    Once you have rendered the audio, as far as the timeline is concerned, the audio is 48khz. If you have rendered the audio and still have "laggy" playback you have other issues.

    Actually, I think you're wrong on the MtD.  I seem to remember people reporting problems with 44.1 audio in a 48k sequence.  Probably a good idea to replace it. 

     

    You could try reconnecting to the 48k material.  Might work, might not.

     

    If all your 44.1 material is on one track, you could duplicate your sequence, delete everything else. and media manage to 48k and then replace the original track with the media managed track.  I think this will work.

    media manage didn't work.  Material was still 44.1

    ah, come on.  You're supposed to insult my mother now.  I guess you're in a good mood cause the weather's nice where you are.  NY is effing cold.

     

    And what's with your avatar or whatever they call it.  Have you gone over to the darkside?  Can't say I blame you.

    I'm so far over on the darkside I can't even see the monitor.

     

    Yes, beautiful weather here today - and for the last several days. Kind of cool, actually - with a high of 73 degrees.

     

    One of my daughters lives in Manhattan, she keeps us posted on life in the great frozen north.

    Just watch out for problems down the road.  More than likely, if the audio's fully rendered, you'll be ok, but if you have weird audio issues, this is the first place I'd look.

    fwiw - you can roundtrip the audio to Soundtrack Pro for resampling. This ought to keep things connected.

     

    Also, If you are using Compressor for this purpose, make sure you take advantage of the batch function.

    If you have FCP7, you have the Final Cut Suite. Which means, you have Soundtrack Pro.

    The official line is this:

     

    1. FCS 3 (aka FCS 2009) was sold only as a suite of applications. The applications were not available individually. You either have them all or none.

     

    2. If you purchase a used version of FCS and you did not receive all the original material (DVD install disks, license numbers, etc) you were scammed and do not have a valid copy.

    fwiw -  I really don't care how you came to be in posession of the software. If you paid good money for it, you were taken. If you pirated it, we don't want to hear about it.

    Just use compressor to batch convert the files.  Threre's a preset in apple:  formats:  audio for 48k 16bit aiffs.  If you need help with compressor workflow, post back.
