use -ss for start time

ffmpeg -ss 00:06:22 -i tmp.webm tmp.mkv

For Amelie:

ffmpeg -i deskshare1.webm -vf "movie=webcams1.webm, scale=210:-1 [inner]; [in][inner] overlay=10:10 [out]" tmp.mp4

ffprobe -v error -select_streams v:0 -show_entries stream=width,height -of csv=s=x:p=0 tmp.webm

Extra

Convert files using ffmpeg adding in the webcam (right justified):

ffmpeg -i deskshare.webm -vf "movie=webcams.webm, scale=330:-1 [inner]; [in][inner] overlay=940:-1 [out]" tmp.mp4

Reversed audio try

ffmpeg -i deskshare.webm -i webcams.webm -vf "movie=webcams.webm, scale=330:-1 [inner]; [in][inner] overlay=940:-1 [out]" tmp.webm
