How to rotate video playback screen?

[manoa]

We have an .avi that was filmed at an odd angle. Is there any way to rotate the play screen 90 degrees?

I don't really want to change the avi - just how it's viewed for consumers.

You must reencode the avi, https://forum.videohelp.com/topic312898.html?highlight=rotate or http://www.microsoft.com/windows/windowsmedia/knowledgecenter/mediaadvice/0075.mspx#EPD

Or else must you include some special video player that can rotate...like ffdshow avisynth filter.

Thanks for the superfast response! I think it's going to be faster for us to reshoot the avi.

Thanks!

If you're going to encode it anyway, then AviSynth's TurnLeft or TurnRight filters will be faster than reshooting:

OK, real newbee question here. My objective: I have an existing .mp2 file that was recorded 90 degrees off (sideways). I want to load this file in Windows Media player upright (TurnLeft).

I have a script with one line

TurnLeft "Compressed_Video_1_1_0.mp2"

I installed AviSynth 2.58. When I run this script (drag and drop it on Windows Media Player, I get a "I don't know what "TurnLeft" means" message.

What am I doing wrong?

If your source is progressive:

DirecShowSource("Compressed_Video_1_1_0.mp2")
TurnLeft()

If it's interlaced it gets much more complex. And note that after TurnLeft() your 720x480 (or whatever) video will be 480x720 so you'll probably want to resize or crop and resize.
