Is there a way to cut movement "dead air" on a screen recording ? [closed]
16 mai 2023, par RaelbeI have got a couple of screen recordings of a painting I've done, and I've managed to concat the files together.


Unfortunately, there is a lot of "dead air" in the video (where I have left my desk, so there is no movement happening on screen) is there a way to cut out this down time ?


I found an example that another artist uses for his screen recordings, so I plugged it in with my file directory's. This is what I used :


.\ffmpeg -f concat -safe 0 -i "merge.txt" -vf npdecimate=hi=64*12:lo=64*5:frac=0.33,seipts=N/30/TB,"setpts=0.25*PTS" -r 30 -crf 30 -an Illu_Test.mp4


I got this error message at the end :


[AVFilterGraph @ 000001cadfe5b1c0] No option name near 'N/30/TB'
[AVFilterGraph @ 000001cadfe5b1c0] Error parsing a filter description around: ,setpts=0.25*PTS
[AVFilterGraph @ 000001cadfe5b1c0] Error parsing filterchain 'npdecimate=hi=64*12:lo=64*5:frac=0.33,seipts=N/30/TB,setpts=0.25*PTS' around: ,setpts=0.25*PTS
Error reinitializing filters!
Failed to inject frame into filter network: Invalid argument
Error while processing the decoded data for stream #0:0`


So I chopped it up a bit and this is what I used to concat the files and it worked perfectly.


.\ffmpeg -f concat -safe 0 -i "merge.txt" -crf 30 -an Illu_Test.mp4


Now, I'm looking to cut out the seconds of no movement. I'm unsure what the -crf command does (as stated I am brand new to this) OG artist states that :


"This is the tolerance level that determines whether there has been enough change between frames or not to be considered as detected motion."


Any help would be appreciated.

How to fix the "No working C compiler found." problem for compiling x264 in Linux ?
27 février 2023, par gc xuFirstly I have read all other solutions related to this problem, including adding path and reinstall yasm, nasm, gcc...
I git clone the source code from https://code.videolan.org/videolan/x264.git.
Then, I run command ./configure, it shows


./configure: line 169: conftest.log: Invalid argument
./configure: line 169: conftest.log: Invalid argument
./configure: line 169: conftest.log: Invalid argument
./configure: line 169: conftest.log: Invalid argument
No working C compiler found.


I check the file "config.log". It shows :

I have read all other solutions related to this problem, including adding path and reinstall yasm, nasm, gcc...
I want to install x264 to configure it in ffmpeg. Thanks for all your answers !
