Any way from MKV back to DV?

[enonod]

Really final...
I converted the same MKV using XMedia Recode direct to ProRes and obtained the below.
[Edit] Note the pixel size is NOT 720x576.
Then used ProRes Proxy and the pixel size IS 720x576 bitrate 15.1Mbps size 6.63GiB
That confuses me.

What is the difference between ProRes , proxy, LT?

Any comments to sum up my results will help me and actually get rid of me.

Thanks

DV ALWAYS has to have 25Mbps (or 50Mbps for DV50, or 100Mbps for DV-HD). A codec trying to follow the rules in creating a DV would use that rate. Same with resolution: DV & DV50 only allow for 720x576 (PAL-land). DV-HD only allows for (thin raster) 960x720, 1280x1080 & 1440x1080.
Not sure about resolution requirements for ProRes...

If your source is already only 352x288, that's a shame - much quality is already lost. That would explain a lot. Going to DV or ProRes ought to bump those to proper SD resolutions, but I cannot vouch for those process/apps/settings used so it's a crap shoot. Things would probably be a whole lot easier for you if your source was already proper 720x576, then relying on the app to control the process automatically wouldn't end up as wrong. The alternative is taking control & specifying yourself, but then you must know the proper #s & settings (and WHY...).

I am so grateful for your knowledge and help Scott. I cannot imagine how I ended up with 352x288, I have others at 720x576 and all were taken with the same JVC camera and that size is not an option. In the days when I knew even less than I do now (is that possible?) and used MakeMKV thinking I was changing only the container, I wasn't. Spilt milk comes to mind. On with the motley!
Thank you again.

Yes indeed, keep in mind, DV is a very fixed format whilst other formats like MPEG-2, AVC, Xvid, etc are quite flexible. (However, MPEG-2 has to follow rules to be DvD/BD compatible, and likewise for AVC to be BD compatible).
