editing compressed videos ( .mov-Sorenson 3)
I have been struggling to figure out why I can import some of my quicktime videos for editing in Vegas and not others.
All of my videos were originally avi files. In Vegas, I have rendered them as:
.mov uncompressed & .mov compressed ( 3 Mbps, Sorensen 3)
Then, I try to open those files in Vegas- the uncompressed is fine but the compressed file opens only with a black screen for video and the audio is fine.
I read the posts about reverting to an older version of quicktime and purchasing quicktime pro ( which I did) and but that didn’t change anything. So, I am wondering if my preferences settings are correct ( I uncheked ignore 3rd party codecs) and I am wondering, is it just not possible to edit video once it has been compressed?
I also have another machine where none of the quicktime files are opening for editing in Sony vegas at all so this question is part of trouble shooting a larger problem.
Any help would be greatly appreciated!
