I just need to see if someone can validate what I'm seeing on my system.
I'm transferring some laserdiscs to DVD (stuff I own that will never be released on DVD or which have been altered between the LD release and the DVD release). The setup is the LD player connected voa a BMD Intensity pro 4K card. The project is set for NTSC 30i. I capture using the capture tool, and expectt he ingested media to be NTSC 30i (720x480). However, the media tool shows it to be an image size of 1440x1080 with a raster dimension of 720x480. The encoding is correctly marked as DV 25 411 (NTSC). The LD is connected over S-Video, and there are no conversions in the BMD desktop software.
Even better, I round trip the video through Resolve with a 30i project and deliver to as 30i using MXF Op-Atom and the Avid NTSC 1:1 8-bit CODEC. This gets written to a separate numbered directory and linked into a new bin. The media in that bin shows up as 1920x1080i, so when dropped into a sequence it gets a FrameFlex applied, forcing another render. If I look at the media created by Resolve using MediaInfo, it's actually SD 720x486 (should be 720x480, but I forgot to change that setting).
So there's two parts to this; First, can someone with a BMD capture card capture an SD source into an NTSC 30i project and then look with the Media tool to see what are the image and raster sizes.
Next, using that media, export an AAF to Resolve, create a 30i project (remember to set it to interlaced in the project settings), do any sort of color correction, and then send it back using the AAF option with the format as MXF OP-ATOM, codec NTSC Avid 1:1 (NTSC), resolution 720x480 DV, PAR 4:3, Flat pass OFF. Send it to a new numbered directory in the Avid Media Files directory tree. In MC, create a new bin and drag the msmMMOB.mdb file to the bin to populate it (you'll have to restart MC to get it to create the database file). Check the Media Tool for image and raster sizes.
A bit of a process to be sure, but something odd is going on and I think it's MC, but I want to make sure.
