I do hear both channels after trimming though and both channels show up in the Audio Mixer as well. This "Channel Mapping weirdness" happens to me as well when i tested it. The workaround is to do all my trimming in the timeline, but what a hassle! Anyone else, or has this been discussed ad nauseum and I just missed it? (Not only that, only the LEFT channel can be heard after trimming.) A check of channel mapping settings will confirm this, at least on my system. However, if you send it to the source monitor AND apply either an "in" or an "out" point, the clip changes from a one to a TWO channel clip. Drag this same clip directly to the timeline and get your expected results. Select "mono" and deselect the left channel (leaving only the right channel checked) and hit OK. Go to clip>audio options>source channel mappings. In the project window, select a clip with 2 channels of audio that has not yet been placed in your timeline.
If I take an image that flickers, the anti flicker filter will stop it at. Thats essentially what the anti flicker filters do anyway. If the anti flicker filter doesnt work, just apply the gausian blur filter in a small dose. Perhaps some filters cause it not to work. Turns out that image had a color correction filter on it also. I used it in a recent project and it appeared to do nothing on one image out of 50. I think the ppro 2 anti flicker filter might have a bug in it. Simply select the opposite of what you want to get what you really want.
That seems to allow you to open them in Pro 9 and 10 but not the reader 10 version. We have had a work around by saving the document again and back saving it back to version 6 Pro. We ahve had this error for two generations of Adobe starting with Pro 8 with long maps above 200 inches. The only work-around is to convert your Photoshop files to another graphics file format before importing them into Premiere Pro.
