Aurora dose not work with the Apple codec. You need to use either Aurora's or Avid's codec.

thanks...but i have another one that already is reg. motion jpega and that one works. are they somehow different that i can't see in QT PRO? one was from after effects, the other from FCP.

I'm sure you have the manual but hears the link:
http://www.auroravideosys.com/suppor...alsdrivers.php

My experience is with the LT cards and they don't support playback of Apples codec, witch is usually what the picture editor delivers. I don't remember what page it was on one of the Appendixes I think.

hope this helps

hey craig,

yes, i do have a manual which i have read, but i don't take offence to your suggestion. and, i remember aurora saying that the apple motion jpeg-a functions virtually the same as aurora's mjpeg-a.

perhaps, the problem lay in the fact that the video i had had ONE field and was not interlaced. from the appendix:

If a 720 X 480 frame of video was created using the Apple™ MJPEG-A Compression Option settings or similar process, but was not interlaced (contains only one field), it would result in a frame that was incapable of being displayed on a video monitor. This is one reason why you could have a movie that looks correct, but won’t playback out the video output connectors.

i solved my problem by putting the QT on another cpu and exporting it to apple motion jpeg-a. then, it worked. i think the eidtor did it as one field because he was trying to fit it onto a DVD-R.

This is not correct. I tend to use the Apple codec more often than the Aurora because id encodes a lot faster. I have never gotten anything with the Avid codec to play, probably because it doesn't come with anything I have. So while it may work for those that have an Avid product it's not a solution for those that don't.

Aurora dose not work with the Apple codec. You need to use either Aurora's or Avid's codec.

Noiz2 is right. aurora confirmed that my problem was that the editor output a single field movie. and he reconfirmed that apple's motion jpeg-a works (almost) like aurora's martian jay-peg-o my heart-ay. when i (re)exported it using QT Pro, it gave me 2 fields.

thanks for the video help in an audio forum!
