Multiply all keyframed motion by a constant?
Hi,
I have several clips with extensive keyframed motion at 480×720.
I would like to see how some of it plays out if I change the sequence settings to HD, which would basically require me to zoom everything in at 225%.
Is there a way to do this all at once with the various keyframes? If not, I would basically have to redo every single point from square one.
Thanks

It’s 100% critical to know your deliverable before starting in Final Cut. If you’re finishing in 720 HD work in 720 all the way through. Slow computer or otherwise, this is the way to work.
Since you’re started you can nest the low res sequence into an HD sequence. This will perform all the moves/scales at low res, then blow the result up to HD, which will be soft. Redoing everything in an HD sequence is the only proper way to handle this situation.

Hi Jeff, thanks for the reply.
Would the best practice not then be to select the highest resolution that your deliverable might be and then edit at that resolution?
The best analogy I can think of is if you were Werner Herzog with the Timothy Treadwell wilderness tapes. Would it be wise to size them all to HD and then do your titles at that level?

Nope.
When you’re hanging pictures on the wall a sledgehammer is overkill. Sure, you’ll get the nail in the wall with a sledge, but you’ll waste a lot of energy in the process. You can build everything in 4k if you like, but if your deliverable is 1080p you’re wasting render time and disc space.

I appreciate your helping sort things out.
While I am working with a lot of originally 480×720 footage, I just feel like that is not the highest resolution deliverable that might come into play down the road.
I guess maybe I should ask…if you were making Grizzly Man, what settings would you do your editing at and what do you think the highest resolution deliverable might be?
I just want to make sure I make the best decision at the outset and have to duplicate any more work than absolutely necessary.

The basic rules:
Shoot to the deliverable (1080i broadcast, shoot 1080i, not 1080p not 720p, etc.)
Edit based on what was shotIf you have a bunch of SD media (720×480) it would be best to edit in SD, then upres at the end.
If you have mixed media edit to the highest quality deliverable, then convert for the others.

I guess the only other thing I’d take your time to ask is that if you were doing some extensive titling and effects in Motion (and at a pretty high quality), and they were compromised by pulling them down to 720×480, would that make you consider up-resing the footage before the edit to maintain the integrity of those effects?
If I shrink the titles and effects down for editing purposes, and then up-res everything at the end, those titles will just be blown-up/zoomed-in low-quality, when they were designed at high quality in the first place. Does that make sense?

the answer to the original question is YES, you can “re-size” all your key-framing if you run the sequence though Media Manager.
Create Offline > Set Sequences to” (you flavour of HD)
gives you a new sequence that you can reconnect to existing HD mediaif you are simply re-conecting to SD media, then i don’t know what the point is,
and maybe it wont workOR
Recompress > Set Sequences to” (you flavour of HD)
this will blow the media up as well.im talking about Video Media.
still image media.. well, i’m not sure what will happen there,
other than to say just use “Create Offline”
that will carry any media that doesn’t have a TC track, like stills and music.if you really want to up-scale your SD media AND motion effects, you might need a 3 step operation:
1 use FCP MM to recompress,
2 do a good quality blow up (FCP MM would probably not be the best)
3 reconnectbut try the simplest way first.

Thanks for the advice. Appreciated.

You mentioned doing a ‘good quality blow up’ and that FCP MM wouldn’t be the optimal tool.
Do you have any recommendations?
And are you aware of any filters and/or plugins that can be used with FCP that produce a better result than just ‘225% zoom’?

As a test, I took one of my 480×720 sequences and customized the setting to 1080×1620, then expanded everything to 225%.
Then exported it, which took FOREVER, and the exported product’s file info says it is 1080×1620, but it plays “actual size” at 480×720…
Trying to figure out why has given me a headache, so I’ll take a run at it tomorrow, but maybe somebody has the obvious solution due to experience…
