Here's the situation: I have a nice video recording (on video tapes), but it was made by someone who didn't realise that turning the camera by 90 degrees is not a good idea. I know that it should be possible theoretically to edit this into a good recording that can be viewed without turning your head (or the TV). Because you can just rotate the video back, right? Frame by frame, hopefully automatically. That's what this topic is about... if you may be able to help, please read on.
Now this recording is to be turned into a VCD that can be played on DVD players common in Europe. That's probably PAL, right? I think the video camera was also PAL. Will have to check that out.
But if I understand this correctly, rotating every frame will swap the resolution XxY into YxX. And since X and Y are not equal in PAL (as far as I know) the rotated frame will have to be resized to fit into the PAL resolution, leaving black bars (either horizontally or vertically). Am I right so far?
What I mean is, suppose the resolution is 352x288, which I think is VCD PAL (not sure). Then if you rotate the recording it will become 288x352, but a VCD PAL device cannot take that: it wants 352x288. The Y needs to shrink and the X needs extra pixels (the black bars). So you will have to resize the 288x352 video to 236x288 and add black bars to fill up the empty X space 352-236=116, so two bars left and right, of 58 pixels each.
The final question is: is there any software that can do this rotation and resizing? For someone who knows video programming it shouldn't be that hard, I think. Each frame is a picture: and even I could rotate a picture, then resize it and fit it into a certain resolution. Manually, with mspaint or IrfanView. But a video is thousands of frames...
The only video software I have available is Pinnacle Studio 10 (which I have never actually used myself) and VirtualDub (played around with it).
