M100 to FCP Follow Up
I had entered post on Friday regarding an FCP DV50 quality issue. I forgot to ask something else though.
I know that when you edit DV25 footage captured through firewire it can start to fall apart when graphics and other renderable items are placed on top of it (technically that is. I know it can be hard to notice). Is this also true for footage shot and captured with DV50?
I’m doing broadcast spots with this footage & want to make sure I maintain good quality as I’ve had with Media 100 for many years.
Thanks, Bugsy -

The same is true for DV50. You lose quality when the video is re-encoded for anything that isn’t cuts-only.
There is a way to avoid this though. Once you’re done editing, you can render everything on an uncompressed sequence. This process does not re-encode the DV25 or DV50 codec. It reads the orignal pre-effects media directly and creates new uncompressed media. So if you master to BetaSP or Digibeta, this is the way to go.

This will happen to some extent no matter what, because in the end, you’re mastering to a vide tape that has some kind of compression and the video will get compressed again even if you edit totally and utterly uncompressed.
However, DVCpro50 is pretty nice compression and will provide a video quality that’s visually losless.

True, it is a good codec, but he’s mastering to BetaSP. So it’s best to render everything to Uncompressed beforehand.
If you master to DV50 over firewire, then you do not want to render it as uncompressed. Use a DV50 timeline and that way only video with effects get re-compressed.

The picture quality difference though will be utterly negligible.

Thanks for the help.
I guess my only decision now is whether or not it’s safe to try FCP with this client or take it back to the trusty Media 100 and its codec. It’s a great codec but I want to go back to the old M100 7.0 interface (dual stream) as opposed to the multiple stream capability of FCP, and other things I’ve fallen in love with, like I want to kick myself in the stomach. (I don’t recommend trying this by the way!)
One question: do I take the finished edit to the new uncompressed timeline and unrender all the titles & effects so they can be re-rendered as uncompressed? Or is there a different way?
Thanks a lot! Bugsy
