AviDemux: which Resize? / Edit + Recode?

[coyote2]

Two questions:

1. In AviDemux I see two "Resize" video filters. Would I be correct in guessing that (the one called "slow",) "Resize" is better than (the one called "faster",) "MPlayer resize"?
2. Before I do the recoding (which along with the above, will also change the audio and video codecs), I also need to edit out parts of the source video. Does it make any difference if I Save the file (with both Video and Audio in "Copy" mode) after editing, and then do the recoding on that saved file, or is it somehow better to recode immediately after editing, and only Save once?

1 - the fast resize is fine, I use it often. Choose bilinear of bicubic. bilinear is a softer picture.
2 - If you can edit out the parts as you like and it looks right in the time line, encode it directly.
not really any need to save it in copy mode first
