I want to convert a 1080p to 720p and also lower resolutions eventually.
I have been using
ffmpeg for all my video processing activities so far, and would simply approach this task using the following command:
ffmpeg -i tos.mov -vf scale=-1:720 tos_0x720.mov
I understand that this will rescale my video to a new frame size having 720 pixels set as a fixed height and the width dynamically calculated.
What I am not sure about are the implications regarding the quality factors of the video when using
ffmpeg this way.
- Is it valid to assume that running this command will output a perfect HD 720p quality video?
- What would be a benefit of using dedicated video conversion software to accomplish my goal compared to running the above command?
