MPEG Streamclip and ProRes 422

OK, it's not strictly FCP but I'm tapping the wealth of knowledge here, also not so much of a major problem as a moan...

I've been using MPEG Streamclip to transcode several camera angles from a concert recording. All other cameras were AVCHD and came in fine through log & transfer and I transcoded to standard ProRes 422.

In Streamclip I used the batch export function and chose the first 422 (there are 2 entries and I assumed the latter was HQ although it's not marked, it just shows as 2 x 422 entries.) In all other apps that give you this codec choice, 422 is first, 422 HQ is marked as such and is second. So I've ended up with a shed load of HQ files and now of course because of the mismatch I can't make my multi clips and I've got to transcode again from the originals, a 2 day process :(

Does anyone know why this is the case and is there an update or any way to clearly see what version of ProRes you are encoding to BEFORE you set off a batch?

Also do you have to have FCS3 to get your hands on 422 LT? Is there a way to get the standalone codec and then will it show up in FCP 6.0.6? Surely if it's just a codec, it should be seen in V.6 if it's on the system?

I've just found a way to sort this problem out. It appears that it's the codec labels themsleves and how they show up in Streamclip that is the issue.

In order to get these to show and also to have access to all the other georgeous 422 codecs and other goodies, download the new QT codec pack:

Then use the little app UNPKG ( ) to unpack the contents by simply dragging the downloaded PKG codec pack onto the app window. This then unpacks on the desktop. Inside navigate the folders until you get to the QT .component files.

Next, drag these into your Library/Quicktime/ folder and then you'll have the LT codecs ( and many others) to use in FCP 6 and all other apps like Streamclip, QT Pro etc. (I would recommend renaming the existing ones in case of problems of course)

I've done a test with it and it works like a charm on my Mac Pro running 10.6.7 and FCP 6.0.6. I'm not able to create an LT sequence but if you create a new one and then drag the material on with the prompt enabled to match settings it will make an LT sequence. I was also able to render out a 422 LT clip from QT Pro and Streamclip to use in the project. All the correct 422 labels also show in the codec lists in all encoding apps.

If you try and install the QT pack on anything not FCP X it will give you an error but this manual installation gets around the Apple Police and their insistence you buy everything new the minute it comes out! You can keep FCP 7 and X, I'm quite happy with 6!
