I am using CapCut for Windows 10. When exporting a video file the file is very huge, increased couple of times. For example: Today I have exported mp4 file which was 1384 MB (1,4GB). The file was 1080p, mp4 and lasted about 60 minutes. I cut off the beginning and the end of the video. Nothing was added. The file was exporting for over an hour. The output resolution was the same, bitrate recommended, mp4, codec H.264, color space SDR - Rec.709, frame rate 30 fps. this is not the exception.

All videos are very huge and exporting them lasts ages. The output file was 2,3 GB. I haven't done any editing, nothing. Just cutting off few minutes at the beginning and few minutes at the end. I haven't change resolution of the video. The same issues I have when creating small files with 9:16 resolution (here I change resolution). Some files can be like 600 MB and they las 5 minutes. By this issue I cannot upload files to my channel which accepts files up to 2GB.
