Advice On Approach: DVD-> Deinterlace-> Edit-> Back to DVD
Advice On Approach: DVD-> Deinterlace-> Edit-> Back to DVD
Greetings. I have a project I’d like to work on with FCP, and eventually author to DVD. Here are the specifics:
1) Extract 4:3 interlaced NTSC from a DVD (non-copyrighted home movie).
2) Deinterlace the stream.
3) Import into Final Cut Pro and edit
4) Re-author the edited content back to DVD.Regarding 1, I have successfully used MPEG Streamclip in the past to demux to M2V and AIFF. This would be an option. Another option would be to transcode to another format. If I choose the second option, I am not sure what that format should be. It seems, though, that keeping the stream in its original format or as close to it as possible would be a good idea. More on this in a minute.
Regarding 2, technically, since the destination media is DVD I don’t really need to deinterlace, but playback will definitely be on progressive TVs so I would rather have tighter control over the images during the editing phase. The video is noisy and was shot poorly with an older camera so it will need a lot of work; this is easier if the content is not interlaced. Here’s the real problem. Final Cut and Compressor (and Streamclip for that matter) all offer simple deinterlacing options. I want to take advantage of more sophisticated deinterlacing techniques like the adaptive blending option in the JES Deinterlacer (https://www.xs4all.nl/~jeschot/home.html#DEI). I cannot find any such deinterlacing methods in Final Cut or Compressor that use both upper and lower fields like this. Perhaps Motion has something. I tried running JES directly on the M2V stream. Unfortunately, JES cannot output the video back into M2V, so I selected DV. The results were disappointing and the file was huge. I’ll concede that my understanding in this area is still weak so perhaps I set the options wrong, or perhaps DV was not the right output format for my purposes.
Regarding 3, this is really the same as 1 and 2. If I am deinterlacing I will obviously need to re-encode. So what is the best format to encode to given that my source is DVD, I need to edit the content in FCP, and my final output is DVD – and I want to limit encoding artifacts to the greatest extent possible?
Any thoughts and suggestions would be greatly appreciated.

Hi Mike,
Transcode your MPEG-2 with MPGStreamclip.
if you want to get the best, do it to 8/10b Uncompress or Proress.
NEVER use “Export to DV. you get a DV Stream, the kind of files used by iMovie.
Export with the very setting of the MPEG-2: Field order, size, pixels..
If you need a good de-interlacing in FC, you need Nattress. Is the only one that works in 10b and have “Smart de-interlacing”.

2. Ripped the video from the DVD to Uncompressed, ProRes or DVCPro50, do not use DV. When you deinterlace save it to that same format.
3. encode back to m2v, that is the only DVD codec. Make sure you encode the new video as progress in Compressor.
