How to rotate .mov 180 deg

Hi folks,

I have .mov files taken in digital camera. The files are 180 deg rotated (upside down). Please advise how to ran Unix command to rotated them 180 deg back. TIA

Avidemux can read some mov files (provided you have the necessary codecs installed). Once you've loaded the video, you can just encode it to any of the available output format, applying the Rotate filter, which let you rotate the video by 90, 180 or 270 degrees.

Sure, try:

Code:

mencoder input.mov -oac copy -ovc lavc -vf flip -o output.mov

Hi colucix,

Thanks for your advice.

I don't have avidemux installed. I have mencoder running on the box.

Hi H_TeXMeX_H,

Your command works for me. Thanks

I have following points not very clear.

1)

Code:

$ mencoder input.mov -oac copy -ovc lavc -flip -o output.mov

also did the job.

2)
On man

2a)

Code:

-oac mp3lame
Encode to MP3 (using LAME).

Whether converting the file to .mp3 format with only sound without video?

2b)

Code:

-vf <filter=named_parameter1=value1[:named_parameter2=value2:...]>
              Sets a named parameter to the given value.  Use on and off or yes and no
              to set flag parameters.

What is the main function of this flag? TIA

yeah, they are synonymous, '-flip' = '-vf flip'.

Well, you choose what the output audio should be, if you want it as mp3 you can use '-oac mp3lame -lameopts q=2' and that should change the audio to mp3. If you wanted no video output just do:

Code:

mencoder input.avi -oac mp3lame -lameopts q=2 -ovc copy -of rawaudio -o output.mp3

'-vf' = video filters, basically just various filters you can apply to video, like flipping, cropping, scaling, deblocking, etc. See:
