Does file size of an encoded video scales proportionally with FPS if a video is encoded in H265 ?
20 juin 2021, par user482594If I encode a raw 60fps video with an H.265 encoder, one with 30 fps and the other with 60fps, would the file size of a 60fps encoded video be as twice as big as 30fps H.265 video ? (assuming all other parameters are the same. e.g. Same CRF/twopass parameters)


In other words, if I happen to encode the same source video with 10 fps, would the outcome encoded video has about 1/6 the file size of 60 fps encoded video ?

How to increase video quality of combined video and audio file using ffmpeg
29 juin 2022, par jettzeongI have a scraper script that I am using which utilizes PRAW module to scrape reddit for media.


To downloaded reddit videos, I have written the code below :


video_url = submission.media['reddit_video']['fallback_url'] 
 audio_url = submission.url + "/audio"
 print('Video: ' + video_url)
 print('Audio: ' + audio_url)
 video = requests.get(video_url).content
 audio = requests.get(audio_url).content
 videoname = "D:\\Bot\\reddit_scrape\\" + submission.id + '_video.mp4'
 audioname = "D:\\Bot\\reddit_scrape\\" + submission.id + '_audio.mp4'
 filename = "D:\\Bot\\reddit_scrape\\" + submission.id + '.mp4'
 
 with open(videoname, 'wb') as handler:
 handler.write(video)
 with open(audioname, 'wb') as handler:
 handler.write(audio)

 os.system(f"ffmpeg -i {videoname} -i {audioname} -map 0:v -map 1:a -c:v copy {filename}")
 os.remove(videoname)
 os.remove(audioname)
 save_to_dict(id = submission.id, ext = filename, txt = submission.title)



What this code does is that it fetches the video and audio seperately from reddit, and combines them via ffmpeg.


However, the video created by this block of code is very blurry and has low resolution.


May I know what kind of argument I can use to make my video file play with higher resolution ?

How can i burn in the current video playback percentage on to a video stream using FFMpeg
25 mai, par David ClewsI've taken alook at the drawtext filter in ffmpeg and it offers the ability to burn in the current local time directly on to the video stream. I would like this sort of behaviour but for a integer percentage value and the percentage symbol % after the actual value. I don't know if this is possible using FFMpeg on the command line. The formula should be something like.


ceil((t/duration)*100)
