DVCPRO hd to offlineRT HD recompress
I have a project that originated on HDCAM – 1080i 29.97 that was digitized with KONA card at DVCPRO HD 29.97. I am trying to use the media manager to make a proxy version at offlineRT HD format for use on a firewire drive with my laptop.
When I open the recompressed project on my laptop, an existing sequence will open fine, with existing clips in that timelne displaying properly. However, any new clips that I try to add to the sequence will display in both the viewer and the canvas at the wrong aspect ratio. I need to uncheck show as sq. pixels in the viewer for it to display properly in the viewer.
The strange thing is that if I match frame out of the timeline from an existing clip that displays properly – it will open in the viewer – squeezed from top to bottom, and if I cut this in to the time line right next to the same clip that was already in the timeline, this clip will display squeezed, while the pre existing clip displays properly. Strange since both clips are referring to the same piece of media.
I believe it to be a mismatch of settings somehow related to the clips generated in the recompress? Square / non square?
Has anyone had this experience, and know how to troubleshoot it?
Thanks,
Jason Lelchuk

Load the squished and unsquished clips into the viewer and compare what you see under Distort in the Motion tab. Sometimes FCP changes or adds a number in Distort without a logical explanation.

David,
Thanks so much, this was indeed the problem! Final cut added -50 adjustment to the aspect ratio settting under the motion > distort tab for all of the new recompressed clips.

Update:
When I open a clip from the browser into the viewer, it displays squished but has no adjustment under the motion tab. Only when it’s put in the timeline, and then reopened to the viewer, is the -50 aspect ratio change noted and correctable. This seems like quite a bug. I was hoping to fix it globally by changing all the source clips in the browser, but if it is only correctable through the timeline it will become quite tedious. Has anyone else encountered this bug, and found a work around? Thanks.

Jason,
Like a number of other things in our beloved FCP, its easy to tell you what’s wrong and how to work your way around it, but a way really fix it, that’s a compeletely different kettle of fish.

For anyone who also has this problem:
The best solution I can find is to right click a clip in the browser, and select item properties > format. Then right click on the current pixel aspect setting. In my case it is reading HD(1280 x 1080) – change it to square and press OK.
This will allow the clip to be displayed properly in the timeline, and will no longer scale the aspect ratio under the motion tab when the clip is added to the timeline.
best,
Jason
