Basic Question... Convert to ProRes422?
on Nov 28, 2012 at 8:53:35 am

I will admit at the outset that I've never really gotten the hang of various codecs and broadcast formats, and I think I would finally like to settle the issue and know what I'm doing in this regard.

I am editing a great deal of DV NTSC footage that sampled as .AVI files.

The resolution is only 720x480, but I am doing a fair amount of titling, roundtripping to Motion, some sound filtering, and so on.

Anyway, I am ending up with TONS of rendering and re-rendering and, in some cases, it is taking a long time and demanding re-renders if all I do is move the files one track up.

Is this a situation where converting to ProRes422 would be wise?

Could someone please outline the drawbacks and benefits of doing so in my situation?

Thanks.

[Bryan Mailer] "I am editing a great deal of DV NTSC footage that sampled as .AVI files."
Don't go the Prores way.
There is an easier and faster way to make your AVI/DV working well on FC and without any quality lost.
You just need to rewrap them as QT/DV.
You can do it just by using the "Save as.." in QT player or in MPGStreamclip.
That just rewrap the A/V information inside the AVI, without any rendering.
You get plain DV/QT.
Of course, when you "Save as.." do it as a "Self-contained movie", no "Reference Movie".

Would just opening the source file in QT and simply Ctrl-S (Save) do the trick? Is it necessary to Save As a new file? I have a number of clips, all 60 minutes long and if "Save" will work, it will be nice not to have to re-link all the editing files in FCP.

Thanks for the tip.

[Bryan Mailer] "Would just opening the source file in QT and simply Ctrl-S (Save) do the trick?"
"Ctrl-S" is not any function (may be on PC).
"Cmd-S" is "Save", but you need "Save as..". That's: "Cmd-Shift-S".


[Bryan Mailer] " Is it necessary to Save As a new file?"
Sure.
You can't change all the "envelope" without writing a new file.
Is not just changing the file extension.

[Bryan Mailer] "I have a number of clips, all 60 minutes long and if "Save" will work, it will be nice not to have to re-link all the editing files in FCP."
The new file will have the same name, length etc, but different extension and probably some other metadata (reel number?). Not sure if FC will re-link it.

Thanks for the advice. Will probably save me about five years of converting, compressing and rendering.

If I have Quicktime .MOV files and I am still running into these ridiculous re-renders, is there something else that can be done? Is .MOV the ideal format for heavy editing?

If you have to render QT files, is because the footage and the sequence setting don't fully match.

[Bryan Mailer] "Is .MOV the ideal format for heavy editing?"
Qt files (.mov) are the only directly supported by FC.

Meaning...you MUST make the sequence match the clip format. To do that make a new sequence, drop a clip into it, when FCP asks "do you want to make the sequence match the clip settings?"...click YES or OK.

If you put a clip into a timeline and you immediately have to render, that's your first clue that something isn't right...and you need to fix it before you proceed.

Thanks for the tips.

It now seems that if I want to experiment with upscaling the footage to something playable as "HD or the best facsimile" that conversion to ProRes422 becomes necessary.

If I understand correctly.

If you are upscaling, the best option is to go to Prores to avoid further compression.
When you use Compressor with the "Frame Control ON", the process is done in Floating Point, so makes sense to put out a 10b codec.
