So far it's looking good, but I can see no way to output keyframes on the second field of a frame. I've tried adding 0.5 to the frame number but that didn't work. but one of the keyframes was silently ignored. Is it possible to do this? This email sent to site_archiver(a)lists.apple.com

The FxTimingAPI allows to to query the duration of your item in the timeline, but we don't currently provide a way for you to change the duration. In case it helps, the user can make filters shorter than the clips they are applied to in Final Cut, as well (but not longer). Almost nobody knows this is possible, but you can do it by dragging in the time bar in the Filters tab. No, there's no way to do that. It sounds like what you actually want is a filter. It will always be the length of the item to which it is applied by default. (In Motion you can make it longer or shorter by dragging the ends of the filter item in the timeline.)

Canvas view of FxGenerator, scaling issue

As long as it is displayed too large fully fit into the canvas (scroll bars come up), it is displayed correctly. But, when that same output is viewed in the Canvas viewer at 27% or less, it looks wrong. Basically, as soon as the image fully fits into the viewer (the Canvas scroll bars go away), it becomes dramatically incorrectly viewed -- like a cropped image. For example, when viewed at 25% the resulting image in the viewer is a zoom in (not zoom out) view of just the upper left corner of the image. (First 25% of X, 25% of Y, blow up to fit the Canvas viewer image). My code is just a dumb copy of the Reference Image directly to the output image. Very straightforward loop of y,x through the height, width of the output image. I'm just testing my parameters out, before I start writing the rest of the plugin. Am I doing something wrong? Is this my bug or a Canvas viewer bug? -- Brian _______________________________________________ Do not post admin requests to the list. They will be ignored.

What is strange is that file extension for dragged image file is shown on the FCP's project window, while that of dragged mov file is not. If the same image file is dragged and dropped from the Finder, it doesn't show the file extension. isStillImage = [[mClipArray objectAtIndex:indexInClipsArray] alpha_id]; if( isStillImage ) { NSString *fileNameInStillImageFolder; NSString *currentFileName; NSRange rangeForFileName; currentFileName = [[mClipArray objectAtIndex:indexInClipsArray] longName]; while( fileNameInStillImageFolder = [dirEnum nextObject] ) { rangeForFileName = [fileNameInStillImageFolder rangeOfString:currentFileName]; if( rangeForFileName.location != NSNotFound ) { // Found it!!!! fileName = [NSString stringWithFormat:@"%@%@/Stills/%@", fileNamePrefix, configPath, [fileNameInStillImageFolder lastPathComponent]]; break; } } } else { fileName = [NSString stringWithFormat:@"%@%@/MOV/%@.mov", fileNamePrefix, configPath, [[mClipArray objectAtIndex:indexInClipsArray] longName]]; } if( fileName ) [fileNamesArray addObject:fileName]; I also used DragPeeker X for debugging D&D.

If this file is opened with the QuickTime player, it shows that timecode track is added. Also, it shows TimeCode Start and TimeCode Stop information for a video tack. However, when I tried inserting a timecode track using QTKittimecode sample program from Apple, the QuickTime player doesn't display TimeCode start and TimeCode Stop information for the video track, although it displays a timecode track. Can anyone tell me what the differences are to have those information for video track or not? When I have FCP open the two file, the FCP correctly displays the starting part of the videos using the timecode. Of if they are different and have different purpose, can anyone explain me what TimeCode Start and TimeCode Stop information in a video track are for?

But I wanted to point out one small problem with your code snippet below. The value returned by -getBitmap::::: is not whether or not the control has an image assigned to it. It's whether or not the call was successful. There may be no image assigned to the image well, and the call will still return YES if no errors occur (which should be always). If you're using that variable to determine whether to use the returned FxBitmap, you will likely crash before there's anything in the image well.
