Convert AVi files for compatibility with 64bit Mac OS?

[roxics]

I have a few dozen DV tapes I captured a few years ago in Premiere Pro. They were captured as AVI files which are no longer compatible with newer versions of Premiere because of Apple's change over from 32bit support to strictly 64bit software support.

Does anyone know of a way to convert these files without having to reencode them to ProRes or H.264?
In other words can they just be rewrapped in a new container or something? I don't want to lose any quality with a reencode because I'll need to edit and color grade this footage.

The AVI files themselves don't care whether the operating system or the applications are 32-bit or 64-bit. They are media files, they are not software.

If I am not mistaken, the MOV container supports the DV codec, so you could remux the AVIs to MOVs with ffmpeg (for example).
However I don't know whether the software you want to use accepts DV-in-MOV

Using ffmpeg to remux to mov:

ffmpeg -i input.avi -codec copy output.mov

Or remux to raw DV stream:

ffmpeg -i input.avi -codec copy output.dv

Also, fyi Premiere on Mac is and has been 64bit for a while. And unless I am mistaken, it no longer relies on QT/AVfoundation to parse & import into the app - they use proprietary 3rd party tools.
