(This is similar to a question I asked in 2014 but I'm hoping there are better options available now, plus we have to take the lack of 32-bit apps into consideration now.)
QuickTime 7 will no longer work in macOS 15 "Catalina" so the time has come to find an alternative.
Playback is no problem, as there are many apps that can playback videos in more formats than QuickTime 7 could.
However, one of the best features of QuickTime 7 "Pro" was that it was able to make simple edits to video files (not just trimming from the start or end, which is all QuickTime X can do).
It also did so without re-encoding the videos, at least for .mov files.
I'm hoping to find GUI app options, rather than, say, some kind of magical ffmpeg
invocation. Bonus points for being easy to use and not having an atrocious UI, but at this point I'm open to just about anything.

QuickTime X seems to be able to open a
.mp4
file, trim it, and re-save as.mp4
with no re-encoding.This was surprising to me, as the only way to
Export
the file is via a filetype change to.mov
.If you take other actions such as
Add Clip to End...
, the menu item forSave
will become greyed out and you will be forced to export as.mov
if you wish to save. If youSplit Clip
more than one time without deleting a segment it similarly prevents the save.But this does enable easy trimming and re-saving without
.mov
conversion using Quicktime X.Trim .mp4 video file:
.mp4
with QuickTime Player XSplit Clip
CMDY to cut the video into two segments.Note: You can also use the
Trim
CMDT command. But I find it is almost impossible to accurately set the In/Out markers without keyboard arrow controls, which do not function in the Trim UI. Instead, useSplit Clip
to delete each end of the trim.Save without re-encoding
Save
CMDS.mp4
. Default value:Export As: Untitled.mp4
Export As...
Note that the
Export As...
menu does NOT contain "pass through" or "original" or any good option.When you select
480p
you are only able to export as a.mov
file.Use
Save
rather thanExport
, which will allow you to re-save as a.mp4
.
