It looks like it is the CMOS shutter issue. Here is a snippet from wikipedia about it:

Partial Exposure. If a camera flash goes off in the shot, the quick nature of the flash may only be present for some of the rows of pixels in a given frame. So as an example, the top 1/3 of the picture may be brightly lit by a flash, while the bottom 2/3 of the picture is dark and unlit as the time it took for the flash to occur was only sequenced in a short amount of time as the CMOS imager sequences a frame. The difference between the two distinct parts of the frame can look odd. Similar problems can arise with emergency vehicle lights, some fluorescent lighting, or any extreme situation where very fast motion or very fast bursts of light are seen in the time between when the CMOS chip sequentially records a frame.

Wow. Now, is there anyway to get around it?

I found a (workable) solution. I had to go to the Presets folder and DELETE all of the WMV presets (I just CUT and pasted them to a new folder). It will now allow a WMV export without a 0:42 crash. I will start putting the presets back in one at a time to find the offending preset.

I have tried nearly all codecs from within premiere pro and have been unsatisfied with the results when compared with the original footage (with the exception of uncompressed AVI which is untenable)

I still to try QT with PNG. Thanks for the tip on that one.

I am PC user and the proud new owner of a Canon 7D. I know that on the Mac side most convert their h.264 to ProRes for editing.

Does anyone have a similar recommendation on the PC for a frame-accurate transcode stream that preserves max quality?

90% PC.

Dave–

Thanks for that reminder about inter-frame encoding. I hadn’t even taken that into consideration as a possible source of the artifacting. As far as 300%, I have had good results with even up to 400%, as long as the footage was intra-frame.

Maybe transcode the H.264 into a more robust stream and try again?

I just found an excellent, and inexpensive solution.

P2Forge. It allows for batch convert of all MXF files into any other format you have codecs for (mostly). But what I have found more exciting, is that it allows the simple rewrapping of an MXF into a simple AVI file WITH the audio files included. Also, this gives you real thumbnails when viewed in normal windows explorer.

This would appear to be the solution I have been needing. You do lose your metadata, but I usually keep that in an excel spreadsheet anyway.

I understand the structure of the P2 file system, and why it exists, but it is a difficult workflow in terms of sharing clips with other end-users. To be able to select a p2 mxf and then output it as a single clip with audio and thumbnail, with no recompression or quality loss is a real timesaver. There is a lot to be said for everything to be contained in one file, i.e. an AVI.

Alex:

Welcome to the (undesirable) club of those suffering from this same Adobe nightmare. It is about to make me miss an important deadline.

Here is one solution. Download a free Mpeg split program to look at your captured footage and then it will “chop” it up into scenes. Re-import the new files it makes into premiere. The audio then should be in sync within each scene.

Here is a link to the program:

Here is answer I found on another thread:

I have had this same issue, and here is the only cure I have found (with help from Adobe tech support) other than going back to CS2.

Re-import your source clips that are currently showing “offline” (perhaps to a different folder). Reimported clips should come in “online” without issue, but of course, they are not on the timeline.

For each clip showing “offline” on the timeline, load the reimported source clip into the source viewer. Right click on the clip on the timeline, and select “Replace with Clip from Source Monitor – Match Frame”. Timeline clip should now be online. Rinse and repeat for your other offline clips.

For added realism for the 3D look (since AE is not truly 3D) add a WARP effect to each page, and use the ARCH mode with the orientation set to horizontal (I think). Keyframe the amount of warp from 0 to 10 (or -10 depending on the direction of motion) for opening, then keyframe from 10-0 when closing (could put in an expression that increases warp based upon angle of opening)

I just did this for a book animation with fairly realistic results.
