Control bitrate of video generated using opencv VideoWriter
20 mars 2023, par darthVI am generating a video from a set of images using

cv2.VideoWriter(filename,fourcc,fps,size)


I want to use a particular bitrate for my output videos to reduce the file sizes. I am trying to mimic a ffmpeg command which generated videos with smaller sizes. One prominent difference I noticed is the bitrate. Resolution, codec, video length are all similar.


How do I change the bitrate when I generate videos using opencv in python ?

ffmpeg drawtext RGB color codes
19 janvier 2018, par Manish JhaI have an ffmpeg command which overlays an image and some text on a video where arguments are :
-i "C:\exports\blue.mp4"
-i "D:\Manish\Videos\logo.png"
-filter_complex
"[0:v]drawtext=fontfile='C\:\\Windows\\Fonts\\arial.ttf':
text='falana dhimaka':
fontcolor=AntiqueWhite:
fontsize=20:x=1000:y=10[text];
[text][1:v]overlay=140:5[filtered]" -map "[filtered]" -map 0:a? -codec:a copy
-preset ultrafast -ac 2 "C:\exports\blue_wm.mp4"This works well, but I want to be able to supply RGB Hex instead of AntiqueWhite. Any help is appreciated.
