I want to download a video (.mp4) with curl but the file is too big, I can't download it in one go. So I try to download just a small part of the video with the --range option of curl, then I want to convert it with ffmpeg to get a lower quality and repeat the process until I get all parts. Unfortunately ffmpeg throw an error : "moov atom is not found". It seems that I need to have fragmented mp4, is curl able to do that ? What other solutions could I try ? Thanks.

UPDATE ffmpeg do the job alone, no need to download the file in several parts, it can reduce the quality of the video as shown here

You can't convert part of an mp4, You need the entire thing. You can download all the parts, recreate the file in whole, then convert.
