[FFmpeg-user] Compilation Video

I am trying to automatically create a compilation video made up of security cam motion videos of relatively short duration (5 to 10 seconds) - kind of like a time-lapse only with videos instead of images. Each video snippet would append to the same compilation video file.  The compilation

Thanks about the USB tip. I’m trying to concatenate automatically, however. We have many Arlo cameras where we CAN connect to the internet. Otherwise, you’re right, we could just use a trail cam but the time someone would need to be spending going through assembling videos would not be

Thanks again for the information!  Sorry for the late reply . . . for some reason, I only just got this . . . I would guess that there is a way to automate that concatenating via FFMpeg and I have a nephew that codes in Linux for a full-time job.  I wanted to ask about the Raspberry Pi group

[FFmpeg-user] Limiting frame rate on encoding videos

I encode videos for Livestream pretty routinely, and I'm looking to automate the process a bit more. Specifically, classic Livestream (which is what I use) has a 25 FPS maximum to use FLVs straight and not re-encode them. I can use an FFmpeg filter to set my output FPS to 25, but that's not

[FFmpeg-user] Two-pass versus CRF: a curiosity question

I'm given to understand that, under the hood, two-pass and CRF are the same thing, just that two-pass calculates the necessary CRF to get the desired filesize. Is this correct? And if so, is it possible to see what CRF was selected in the two-pass encoding? I'm experimenting with encoding two
