Using kdenlive v23.08.5 in UbuntuStudio 24.04 LTS.
I’m new to video and kdenlive. I am trying to produce a short video for a brand ad on Amazon. I’ve made a 20 second clip using project settings HD1080p 25fps which seemed to be ideal. After rendering, Amazon rejected the video because of a video bit rate < 1Mbps.
Investigations lead me to try using a command line tool ‘melt’ to operate on the video.kdenlive file. My first attempt after checking the presets in /usr/share/mlt-7/presets/consumer/avformat/hdv_1080_25p/HDV was:
melt file.kdenlive -consumer avformat:output.mp4 vcodec=mpeg2video vb=3500k acodec=mp2 ab=384k
This did indeed produce a video with a high enough bit rate as evidenced using ffprobe on the command line. This video would display on VLC and Haruna but not on Windows media player. Amazon rejected it again because for their brand ads, they require the video to use H264 or H265 codec (mpeg2 codec is acceptable in other ads but not brand ads).
I tried replacing ‘vcodec=mpeg2video’ with ‘vcodec=libx264’ and this gave me an output video using H264 codec but of only 423 Kbps bit rate. Clearly, my choice of vcodec was wrong.
I haven’t been able to determine how to define video bit rate inside kdenlive. I’m hoping someone can help me to turn my 20 second video clip into one using H264 codec and with a video bit rate > 1Mbps.
