 Posted: Tue Nov 22, 2005 4:15 am Post subject: How to rotate a video |
 |
|
I took a short movie with my Canon camera. I copied the file onto my Gentoo box. The file created is an AVI. The file plays fine with mplayer, xine and totem. The problem is that the video is sideways. I need to rotate is 90 degrees.
Totem says it is a motion Jpeg.
When I try to load it with Kino it says "Failed to load media file".
I can load it into Cinelerra but there is no video playback.
How do I rotate this video?
Thanks

Kino is designed for DV streams, this is the same format but far more restrictive than just Motion JPEG.
I would use transcode or, if you are not so good with cryptic command line options  avidemux2 |

Excellant!!!
I already had avidemux2 and didn't know it.
Thanks

Hi guys,
I am trying to do the same and I would like to use transcode since avidemux is masked for my amd64. The ~amd64 package is file with a bug and I dont want to install it since it is not considered stable and it has known bugs.
Does anyone know what to do to rotate the movie using transcode?
Thanks! |

Sorry not to answer your question completely, but who knows it helps... (Since I don't know transcode)..
mplayer both has a version in AMD64 and ~AMD64 and it does support rotating..
from the man page:
| Code: |
rotate[=<0-7>]
Rotates the image by 90 degrees and optionally flips it. For
values between 4-7 rotation is only done if the movie geometry
is portrait and not landscape.
0 Rotate by 90 degrees clockwise and flip (default).
1 Rotate by 90 degrees clockwise.
2 Rotate by 90 degrees counterclockwise.
3 Rotate by 90 degrees counterclockwise and flip.
|
Both in realtime playback (no need to turn) and in recoding if you want to distribute...

Actually I tried that without success. I did a mplayer rotate=1 movie.avi
And all it displayed was the same movie as with mplayer movie.avi.
I read many posts and many how to to use mencoder but I dont have that with my mplayer. I also tried to rotate the movie with mplayer and several other options that didnt work either. So I decided to try transcode.
But thanks for the suggestion anyway. Will continue looking. |

The manual page I quoted is refering to the video filters sections, I guess it would have been handy if I had mentioned that...
So,
| Code: |
$ mplayer tmp.avi -vf rotate=1
|
will do the job...
Likewise re-coding... (using default settings)
| Code: |
$ mencoder -oac lavc -ovc lavc -vf rotate=1 inputfile.avi -o outputfile.avi
|
I assume the use flag encode is needed to get mencoder...
But really there are many settings and the manpage is usefull...

| Thanks! The mplayer command worked. And I emerging mplayer again with the encode flag. I didnt know I needed this flag to have mencoder. |

Hi SZwarts, so I installed mencoder using the encode. I dont know if you can continue helping me thoug 
When I ran mencoder I got a sampling rate error. Do you know what it means?

I think you need some more encoding options, something like "-lavcopts acodec=mp3:abitrate=96:vcodec=mpeg4:vbitrate=500". They are all listed in the man page under "lavcopts".

Daniel

It cant find the "mp3" encoder. I compiled my mplayer/mencoder with mp3 set. Do you have any idea what is missing?
This is the output:

The error you are seeing is actually that mencoder can't open the mp3 codec at a bit rate of 96 kbps and a sample rate of 11024 Hz. But the error message conveniently leaves out that last bit.
I have the same problem, also with stuff from a Canon camera. The camera generates a mono audio stream using a sample rate of 11024Hz, which is non-standard, and the lavc mp3 codec barfs. The standard rate is 11025Hz. Somebody at Canon was off by one that day, I guess. Luckily, you can force mencoder to resample using the -srate option:
| Code: | | mencoder -oac lavc -ovc lavc -lavcopts acodec=mp3:abitrate=96 -srate 11025 file.avi -o file.out.avi |
Unfortunately I've found that the result has really, really bad audio/video sync (out by seconds at the end of the video). I don't really know if this is to do with the resampling or not. I suspect that getting the sync right can be tricky in general because I've seen quite a few videos people have made with bad sync. But I'm new at this too. The best audio sync I could get was by telling mplayer to simply copy the incoming audio stream, like this:
| Code: | | mencoder -oac copy -ovc lavc file.avi -o file.out.avi |
But that leaves the original 11024Hz audio in the file, and some players have trouble... mplayer is fine, but totem with the xine back-end really hates it, lots of audio distortion. And even then, the sync isn't too good, it still gets noticably out in places, although it's not miles off at the end.
Let me know how you go! |

Hi kimmie,
I tested your suggestion here and you are right. It does work when I resample the audio stream but then the movie only playback with audio using mplayer.
BUT if I copy the audio stream:
mencoder -oac copy -ovc lavc -vf rotate=1 in.AVI -o out.AVI
Then I get a useable file. If there is any delay I couldnt appreciate it with my short length movies. I have some longer ones but it will take me some time to go over all my movie collection to find one of my 3 minute movie.
Thank you for your input! It probably solved my problem! |

Glad that worked for you.
I found out a way to improve the sync and get a file which works with both mplayer and xine:
- Extract the audio from the original file as a .wav file
- Encode the .wav to an .mp3 using lame
- Recode your video, muxing in the audio you just encoded
| Code: | mplayer -vo null -vc null -ao pcm:file=IN.wav IN.avi # note 1
lame IN.wav IN.mp3
mencoder -oac copy -audiofile IN.mp3 -ovc lavc -vf-add harddup IN.avi -o OUT.avi # note 2
# Notes:
# 1. It is normal to get the "Your system is too SLOW to play this" message here (see mplayer man page)
# 2. harddup video filter improves a/v sync (see mplayer manual section 14.1.12).
# I tested this, it did help in my case |
I've tested this with 3 minute vids, and the result is fine. |
