fix upside-down divx without re-encoding?

[vonzippa]

I recently created a Divx .avi, and due to a known bug in the Divx 6 YV12 pass-through, my video is flipped vertically. I am aware that there are options to make the playback flip the video, but then every other video that is not flipped, will then be flipped, therefore that is not an option. I also know that Virtualdub has a 'vertical flip' filter, but that requires full-processing mode, and after spending 9 straight hours encoding this video on the 'insane' setting, I don't want to do it over. Is there any possible way to flip my video to the correct orientation without re-encoding it? Or some method that could flip the video without degrading the quality of it? Any help would be greatly appreciated.

Flip your monitor over?

Alrite alrite enough nonsense. Not sure if it will work with your Divx encoded stuff, but ffdshow has a 'flip video' switch in the settings (worked for me before actually). You may want to give it a try.

I appreciate your reply, however ffdshow is, unfortunately, not going to solve my problem. It does have a playback filter that can flip the video during playback, however, as I stated in my original message, this is not going to work. First, I would have to manually change the flip option in the ffdshow options for this particular video, and then change it back for everything else, or else every other video would now be flipped, when they shouldn't be. I don't seem to be wording this very well, but I need a more permanent solution. Second, if I wanted to send this video to other people, it would play upside-down on their systems as well, and then they would be sharing the burden of how to get this thing right-side-up. I'm not looking for something that flips the video as it is playing, rather I need to find a way to edit the video itself and make it be vertically flipped. I really don't want to have to re-encode this video, as I spent a great deal of time encoding it, and would hate to do it over again, and it seems to me that flipping the video should be something that is possible without re-encoding the entire video, but perhaps I'm wrong.

The answer is no. You cannot permanently flip the video without encoding.

There is one method though. Load the file in avisynth with
Avisource("yourfile.avi")
Flipvertical()
Then save the avs script and play the script instead of the avi.

Thanks to all who replied. I guess I have no choice but to re-encode. -_-
