Final Cut Pro X 10.4.1 randomly deleting clips.

I had the same problem. Another user of this forum gave me the advice (in another thread) to only use command + clicking to select multiple clips. He received this advice from the apple support. They told him not to use shift select or dragging to select multiple clips as that seems to cause the arbitrary selection of more clips (sometimes not all the time). It seems to be a reliable workaround. At least in my last editing session I had no more suprisingly deleted clips. An the user I got this tip from told me the same. So I hope this can help you to avoid more nightmares.

Nevertheless I really hope that Apple fixes this soon.

The latest version of Command Post, beta 28, provides a solution for the clip selection bug. The plugin has a clever solution. It monitors when you are selecting clips and, if it detects other clips becoming selected, it deselect them. I have only been using it a short while, but it is very fast - I haven’t noticed any slowdown during the selection process. Check it out at commandpost.io.

FCP 10.4.2 update is supposed to fix the problem.

The 10.4.2. update solves this problem completely.

This is a major bug when dragging to select clips. It's occasionally selecting additional clips elsewhere in the project other than what you highlighted. Then anything you do will also happen to those other clips too -- like deleting, for example. This was driving me crazy and then after complaining on Twitter, someone shared this great video showing off the problem:

I spent some time on google searching for a 10.4 download link until I found one that worked. Not having any issues with it, the clip deletion issue isn't happening so I'm happy. Any projects made in 10.4.1 wont be able to open in 10.4 but new projects work great. I'll switch back when they fix this issue.

Update to 10.4.2.

Me took when editing in multicam. I have lost hours and hours in the edit trying to reassemble sequences! I have worked out that it is much much worse if I use any dissolves in the sequence, and so now avoiding any transitions. Ridiculous! Can't wait for a solution!

I'm having the same issue too. Sometimes I'll select a clip in the timeline to delete it and then I zoom out and a random set of clips in my timeline also get selected. So when I delete the clip I intended the other clips are going with it. It's driving me crazy!

I have exactly the same problem, I don't know after which editing operations other clips in the timeline are selected and deleted. I use multicam clips as well in my actual project and have arbitrarily deleted clips in each editing session, which cost in total a lot of time to recover.

I talked to support yesterday and they tried to blame it on me editing off of an external hard drive... I just “found” an old copy of 10.4 online and was able to install it. I’m hoping that’s a temporary fix until they update.

I have this problem too. Editing a feature film, randomly clips and scenes disappear in a completely different section of my two hour timeline, than the section I was working on - deleting or moving clips. I must triple check everything before viewings with BBC and BFI and other coproducers. Complete nightmare.

Apple! Solve this quickly! I stood by FCP all along the way, did already 10 feature films with FCP X, managed to work around all the little bugs and hick ups, but this bug is too BASIC. I need to trust that as long as I didn't touch any scene anywhere in the timeline, it will still be there. If I lose that basic trust, you will lose me.

I use no plug ins in any clip.

It's happening to me too. Simple single-cam project, no plugins used. I normally place the playhead somewhere, press shift+cmd+b to cut, then click+drag to select a chunk and press "delete" to delete. After I spent a few hours editing my project, I noticed random clips were missing through the timeline 😟.

Please fix this ASAP Apple!

Anyone know if there's a way to downgrade to 10.4.0?

I have this problem.When import clips into a timeline and use ripple cut,random clips delete.This problem only in the 10.4.1 version.It's a big very problem
