FFMPEG fit 1920x1080 video in 1080x1920 video (Instagram Reels)
10 mars 2021, par tjalloI am trying to post a video on Instagram. My current video is 1920x1080, but for Instagram reels it needs to be in 1080x1920 resolution (Basically Vertical). But instead of posting the video on its side, I like to post it with black bars (see image below). But I don't know which transform commands I need to use in ffmpeg to make this work (and also couldn't find any relevant posts).

Overlay a video with rounded corners - FFMPEG React Native (Like Facetime or other Video Chats)
25 février 2024, par Christopher GabbaI'm trying to overlay one video on top of another using FFMPEG, in the exact same format as FaceTime, but the video would have rounded corners. I've tried the commands on other posts but they all generate unexpected results or errors.


Here is the command that overlays the videos decently :


-i main_video.mp4 -i small_overlaid_video_in_lower_left_corner.mp4 -filter_complex \
 "[0:v]scale=iw:ih[main_scaled]; \
 [1:v]scale=iw/2:ih/2:force_original_aspect_ratio=decrease,format=yuva420p[reaction_resized]; \
 [main_scaled][reaction_resized]overlay=x=40:y=H-h-40:format=auto[final]" \
 -map "[final]" -map 1:a? -c:a copy -c:v libx264 -crf 18 -preset ultrafast -t -y output.mp4



The problems this has is that the main videos resolution varies from video to video, so sometimes the overlaid video is super small and sometimes its too big. Three questions :


- 

- How do I make the overlaid video the same size in comparison to the main video every time ?
- How can I apply rounded corners on the rectangle ?
- How can I modify it to include both video's audio ?
