Replacement for MPEG Streamclip: A/V Passthrough Option Needed

Previously, I used MPEG Streamclip (MS) to extract small clips from larger GoPro and BlackVue dashcam files, prior to FCPX import.  With the new laptop (M1), that's no longer an option since MS is a 32-bit app.  Any suggestions?  HandBrake does not support video passthrough.  Thanks in advance.

FFWorks is my go to app for conversions: www.ffworks.net .   See if it can do what you want.

Thanks.  I saw a reference to FFWorks elsewhere online earlier today.  I'll check it out.

Another option is Shutter Encoder. Free, but donation requested. I'm not sure about passthrough, though. Telestream Switch does offer passthrough, but it only encodes one file at a time - no batches. It's also a bit pricey.

QT Player is an option as well.

Thanks all for the suggestions... I downloaded ffWorks [...finding and installing the correct ffMPEG file was somewhat of a challenge...] and did tests with that and QT. MediaInfo indicates slight differences between ffWorks, QT and MPEG Streamclip, but the sizes of all three files are very close. I liked MPEG Streamclip because everything could be done with keyboard shortcuts (about a half-minute workflow per file). ffWorks and QT workflows are not (apparently) supported by kb shortcuts. No big, as they say...

Doesn’t Apple Compressor do that too? Pretty sure I have used pass through on Video and Audio before. Been a while.

Yes, you are correct...

I might consider getting that in the future.  At $50 (the price of a typical plug-in), it's fairly reasonable.

Having Compressor as part of your FCP workflow is absolutely essential. I would potentially consider Motion to be an 'optional' add on, but Compressor and FCP are crucial for so many workflows.
