Nothing too complicated - put the position data into an array, and depending on the frame number, pull out the correct data and create a poly that is used to blit the source image to dest. But unfortunately things aren't that simple and I'm seeing problems. Using BlitRect, produces strange 1px wide notches at the top of the image. http://img.skitch.com/20100225-eju98ny9eki68bpwyskmigbbsd.jpg When using Blit, the notches are gone but there are now near-horizontal missing lines on certain frames, depending on the corner coordinates of the poly. http://img.skitch.com/20100225-kqwcghsxfc4h264uwksagnx9kd.jpg So then I thought I'd workaround it and create a separate alpha channel, using FillPoly but that won't work because it seems to ignore subpixel values as the poly moves around. It's a long shot but anyone on the list ever seen these issues before and got any handy workarounds? I did try drawing the top 5% of the image using Blit and the remaining 95% using BlitRect :-) but the antialiasing is slightly different on the vertical edges so you can see the join.

Re: Final cut pro 7.0.1 using the wrong data ref for media segments when there is more then one in track

site_archiver(a)lists.apple.com Delivered-To: Pro-apps-dev(a)lists.apple.com Yet another interesting piece of data: If I render the time line to a QuickTime MOV, the output is correct. It is only while editing that the first media segment is missing or using the wrong data references. Also, all other QT compatible applications I have seem to work fine.

Final cut pro 7.0.1 using the wrong data ref for media segments when there is more then one in track

site_archiver(a)lists.apple.com Delivered-To: Pro-apps-dev(a)lists.apple.com Hi All We have a import/export component for FCP/QuickTime that is working very well in general, but there is one issue we cannot resolve. For one of our formats we need to stitch together multiple video and audio files to make a complete A/V clip in FCP. If there is only one video file and one audio file per track, everything works perfectly in FCP and QT Player. If there are multiple video files and multiple audio files, everything works perfectly in QT Player on OS-X and Windows, but in FCP the video media segments are missing the first one, or more likely, FCP is using the dataRef from the second segment for the first, the third segment for the second, etc. The result looks like this: QTPlayer: Track 1 | -- video 1 -- | -- video 2 -- | -- video 3 -- | Track 2 | -- audio 1 -- | -- audio 2 -- | -- audio 3 -- | Track 3 | -- audio 1 -- | -- audio 2 -- | -- audio 3 -- | Track 4 | ---------------------- time code ------------------| FCP: Track 1 | -- video 2 -- | -- video 3 -- | -- black --| Track 2 | -- audio 1 -- | -- audio 2 -- | -- audio 3 -- | Track 3 | -- audio 1 -- | -- audio 2 -- | -- audio 3 -- | Track 4 | ---------------------- time code ------------------| I have tried adding a fake dataRef to another file with no media in the video track, but this does not help. Does anyone have any idea what is going on?

site_archiver(a)lists.apple.com Delivered-To: pro-apps-dev(a)lists.apple.com Certainly - improvement is always the goal. I'm just curious from a "what else might we witness that's unexpected" standpoint. As I mentioned, my calls requesting XML data to my tools have been successful, so I'm not affected by the sending issue either way. I'm just curious - and that's what helps me improve MY work :-).

site_archiver(a)lists.apple.com Delivered-To: pro-apps-dev(a)lists.apple.com Tim, We made it much more robust. My description can't really get more detailed since I didn't do this work an it was over a year ago, so I don't remember the exact details of what all we changed. But the point is that we tried to anticipate places where people would run into trouble and route this error cases into non-failures if we could. I don't really see what is wrong with having improved something over 2 releases such that more things work.
