Interlacing Issues
Im having an issue with my graphics and an interlacing problem. We are recording to a Tricaster 300dx and laying hq graphics over top. The initial output is beautiful… and when I pull the MPG files it looks good but when it is converted to the xdcam format (which is the only losless conversion from the tricaster to a Mac FCP system according to NewTek) it interlaces.
Is there a way to prevent this interlacing… I assumed that since the original file was not interlaced and the graphic is not interlaced… and I am still selecting the deinterlace function when rendering that there would be no interlacing but its there.
Is there a fix to that?
Here are examples

Don’t know what the Tricaster can or can’t do but surely it can output an uncompressed 10 bit 422 maintaining the 1920 x 1080 ratio of the original.
XDCam is a highly compressed format, plus you are changing the pixel aspect to 720. It is far from lossless.
If uncompressed is too tough to play, then convert that to ProRes in Compressor once you have bought the file into you FCP Mac.

can you NOT select the de-interlace function?
720 shouldn’t be interlaced anyways. its a progressive format.
my other advice if I read you correctly is to just play out from the tricaster
and capture the component or sdi output from it, into another final cut system. -
I will try the Pro Res idea… I haven’t tried that as a format yet… and hopefully that will work.
As for the deinterlace option…. I select that and the graphics still come out looking interlaced…. the video portion is fine… only the areas covered by graphics seem to be affected.
As for capturing to another fcp system on the fly… we will be going live for 9 hours and will have to capture for 9 hours straight… the tricaster allows you to make breaks on the fly and will make the file sizes far smaller… so unfortunatly going to another system is not an option… but thanks for the suggestion.
I will let you know if the pro res helps…

and if you de-select it does the same?
