[FFmpeg-user] converting yuv directly to Apple Final Cut Pro

[Roee Kashi]

Hello,
In order to convert my YV12 video into apple pal-dv format (in order to be
supported in Apple Final Cut Pro) i'm using the following command:

ffmpeg -y -i aud_file.mp3 -s 528x384 -vtag YV12 -i raw_vid.yuv -target
pal-dv outdv.mov

it creates a dv-pal mov file, which works fine in a player like VLC.
( * note to users who tries this command and it doesn't work: in older
ffmpeg versions -vtag YV12 was applied for both input and output file, and
in newer version the vtag can be added as an input option )

so this mov file looks ok, but the final cut don't accept this file.

in order to solve this (i found it out by mistake) i'm adding this command:
ffmpeg -i outdv.mov -vcodec copy -acodec copy -sameq -strict -o outdv2.mov

this time the file outdv2.mov is accepted in final cut.
i don't understand why are they different.

1) ffmpeg -i outdv.mov

to this kind of mov file?
Thanks.
