Any ffmpeg recipe to clip off those TikTok/Instagram logo/noise from the end of videos? : foss

I can think of one: it's FUCKING annoying, I'd be quite fine with the creator watermark in the video itself (and many do so), but that extra tacked-on logo clip, usually at 2-3 times the volume of the clip itself, is EXTREMELY annoying, i understand what you say but this is also a legitimate reason

Since the primary complaint is unbalanced audio levels, perhaps the better question would be how to construct a command to normalize the audio of the clip rather than removing the attribution to the creators.

For both platforms, the uploader's username shows throughout the video when downloaded, not just at the end. Removing the part op wants to get rid off does nothing to prevent knowing who the original uploader was.

I would try the -to option with a negative duration. (I'm assuming negative duration counts from the end of the file instead of the beginning.)

I think this is the easiest. But, -to can't do negative times. You need to nest a different comment inside the FFmpeg command to to the math.

I think this might work to remove 2 seconds from the end of a video

ffmpeg -ss 0 -i in.mp4 -t $(( $(ffprobe -v error -show_entries format=duration -of default=noprint_wrappers=1:nokey=1 in.mp4 |cut -d\. -f1) - 2 )) -c copy out.mp4

I would recommend checking out LosslessCut. Behind the curtain it runs ffmpeg, so you should be able to find the perfect command.

In the features list:

View ffmpeg last command log so you can modify and re-run modify recent commands on the command line

This is my (controversial) tip: ask an LLM. It works wonderfully for these cases. "Give me an ffmpeg command that cuts the last X seconds of a video in a lossless manner, stabilizes it and speeds it up 200%".

You can then checkout those commands on the manual/online to verify.
