How do I get “duplicate frame warning bars” (tried the obvious)

[Willie Stevenson]

For anybody with the same problem:

Not only do you have to have the SHOW DUPLICATE FRAMES option on in the user prefs but you have to go down to the little black triangle in the lower left hand edge of the Timeline Window (between the track hieght toggle and the timeline expansion slider). In the resulting menu is “show Duplicate Frames”… turn it on.

Silly me, I didn’t even know about that triangle and have must have pressed it by accident…. twice!

Anyway

I think you might be confusing user prefs with sequence settings. If you turn it on in user prefs it’s going to be on for all new sequences. But if you already have a sequence, you’ll need to turn it on in sequence settings or that little spot you found.

Also, be aware that running with this “dupe detector” on may significantly slow down your system performance to the point where it is unusable. FCP looks at ANY sequence in your project that has dupe detect turned on. Therefore, if you’ve got a dozen versions of a one hour sequence in your project, FCP is going to search every single one of them looking for dupes. As you can imagine, this will take a long time. THerefore, you may NOT want to run with this feature on at all times.

I run this feature at ALL times. I’m currently on a project and will have up to 10 sequences open, each 5-10 minutes long, sometimes more. There is no difference in performance if I have one open or 10 open, dupe detection on or off. So use your own judgement. I’m only running a G4. Dupe detection does not look for dupes in other seqeunces, but all sequences may be looking at once (which does seem silly programming wise, there’s no reason for a background window to be searching for dupes when it hasn’t changed). So just know that turning on anything in your sequence might slow it down. But I’ve never seen any slowdow with dupe frames. Now if you turn on show waveforms, that’s a different story. I don’t ever turn on waveforms.

Brett,

Just because you haven’t personally experienced it, doesn’t mean it doesn’t occur. With close to one hundred systems under our roof (all connected to X-SAN) we see alot of things that many users may never experience. Please be careful about making definitive statements (“dupe detection does not look for dupes in other sequences”) unless you know it to be absolutely true. My experience with this feature on multiple large projects with long timelines shows that “Dupe detection” turned on in ANY of your projects (open or not) WILL cause a slow down.

So even a closed project (no bin, no timeline) would cause slowdowns ? I’m not sure how this is possible. Dupe detection is contained in the project file, not media… how can a *closed* project could ever affect other projects ? Are you sure it’s not coincidence ?

btw… in my experience scrubbing and scrolling stay fast with dupe detect, but trimming can become really slow (1-2 sec lags).

i think, in this instance, the intended meaning was a not ‘closed’ but rather ‘inactive’ (ie not the project containing the currently active timeline) … thats my interpretation anyway
