I appreciate non-destructive editing, but with video trimming, I often want to trim off the beginning and end of the video permanently to save lots of disk space. What's the best way to accomplish this in Lightroom 4?

You'd have to export, import the export, and delete your original. Since this requires re-compression, I wouldn't do it.

That's too bad - I was hoping that Lightroom's trimming wouldn't require re-encoding the video. I guess I'll have to use another tool for video trimming.

If anyone from the Lightroom team is reading this - it'd be great for Lightroom to support this scenario. Video files obviously take up a ton of storage, and when you have a 3 minute video of your kid and they only did something interesting in 30 seconds of that video (very common - if you have kids I'd bet you'd agree), then being able to permanently trim the video without quality loss is a killer scenario.

There are other tools out that that, at least for some video container formats, support lossless trimming - it'd be great to have that built in to Lightroom.

I'd ask for a feature of video that is called "Direct Stream Copy" in VirtualDub. Several operations you can do to a video don't require transcoding (trimming, changing frame rate, decimation).
