  • how to replace LoRes clips with its HiRes versions

    Posted by Juan Lesta on March 28, 2024 at 9:06 pm

    I am editing a small video using stock footage.
    I used LoRes clips versions before purchase them.
    After I had the OK from my client I need to replace the LoRes clips for the HiRes versions I downloaded.
    I only find info about how to operate with proxies, but I think this is no this scenario as LoRes clips are no generated by FCP.

    Any idea to figure out how to replace the LoRes versions with HiRes versions avoiding to redo the entire editing clip by clip?

    Thanks a lot in advance

    Unfortunately, there’s no quick solution. You need to drag each full rez file over the low rez one and select “Replace from start.” If you have applied any transforms or effects to a clip, before replacing the clip, first copy it (CMD-C), then insert the high rez clip, and Paste Attributes (Shift+CMD+V). That will apply all the transforms and effects (which may need to be tweaked). If you’ve edited parts of a clip, you may have to line up each part separately.

    What I do when I’m using temporary audio or video files is first turn each into a Compound Clip then edit the compound clip. Later, when you get the high rez version, replace it into the original Compound Clip and all your edits will be preserved.

    Is the issue timeline sizing?

    Are the clips the same name?

    If your proxy timeline is different but same aspect ratio, you can just change it to whatever the final is after.

    however diff issue if the clips are not the same name.

    Thanks John.
    Clips have identical duration, but different name. If I use the Replace function the in point is not applied so it doesn’t work whatever function I select (Replace, from begging, from end…)

    Compound clip could be the better option, I will try.

    If there is any hint of the same characters in the Hi res file, you can use an app to remove/add characters and see if that works.
    Ugh that was one of the fixes back in my Avid days 😛

    I use an app called NameChanger religiously 🙂

    1st, there is no built-in way to replace your own proxies with your own originals. FCPX demands it handle everything. 2nd, it’s actually rare you need to use proxies in the first place.

    But now that you have used low res images, you’ll have to import the full res versions and manually match them up. There’s no automatic way to do that in FCPX.

    Surely there is a way using an XML editor.

    I would have to dig up some old posts to find that.

    I have the same issue, and would dearly love Apple to create an easier way to do this. Something like After Effect’s Command+Option+/. This is the best method I have found for swapping a shot in FCPX. Note, I usually edit in secondary storylines above a dummy main storyline. If you edit on the main storyline, you could lift the proxy clip from the storyline first.

    First, park the playhead at the beginning of the proxy clip. Drag the head of the proxy clip to its extent. Next place the master in a layer above the proxy clip and make sure their in points match. Drag both proxy and master in points back to the playhead. Copy the proxy clip, then Paste Attributes (Command+Shift+V) onto the master clip. Copy any transitions from the proxy to the master. Toggle the Master visibility on and off to make sure it matches the proxy. Delete the proxy. Merge the master back into the primary storyline if necessary.

    Thats a lot more busywork steps than it feels should be necessary. It goes pretty quickly once you get the hang of it though. One nice thing is that if both proxy and final are the same aspect ratio, and set to spatial conform “fit”, all transforms, KenBurns crops, color correction and effects are transferred perfectly.

    Hope that helps!
