bonjour
c la premiere fois que je me sert d'une camera numerique pour le boulot.
Je suis allé en deplacement et ai fait une video en mode... portrait au lieu de paysage.
Je croyais que je pourrais facilement retourner cela en mode paysage sur iMovie mai je trouves pas.
Qui peut m'aider à renverser cette video dans le bon sens?
merci

A: If necessary, open the clip in Q...: PAL/NTSC with the following other settings:page :
How can I convert vertical video to DV or rotate DV (and preserve interlacing) [

vertical, square pixel progressive video from a still image camera. When I import it to iMovie, the clip is stretched horizontally. How can I maintain the aspect ratio?
A: If necessary, open the clip in QuickTime Player Pro 7 and
rotate it 90° (via Window/Show Movie Properties/Video Track/Visual Settings/Flip_Rotate) so it is displayed vertically. Then do a File/Save As... It is possible to add a 4:3 mask to the clip with the QuickTime Player (see
here,
here and
here), but using
MPEG Streamclip could be easier for most people and it is also more flexible. Open the now vertical clip in MPEG Streamclip and export it via
File/Export to DV... with
Compression: DV (DV25) and
Standard: PAL/NTSC with the following other settings:
For a 4:3 iMovie PAL project: Export a vertical 480x640 clip as PAL-DV with Aspect Ratio:
4:3 and
X/Y aspect ratio 0,5625 [=(480/640)/(702/576)/(128/117) -- you can calculate the X/Y factor for other input ratios as well]. To remove the letterbox with
vertical input, you can use a Zoom factor of 182% [=(720/576)/((480/(128/117))/640)]. (702/576 is the actual active picture size and 128/117 the
pixel aspect ratio for PAL DV).
Conclusion :
Payant : Quicktime Player Pro 7 et MPEG Streamclip... ou alors
Gratuit :
Qtcoffee en ligne de commande (Faut aimer !!).
Il y aussi un
plug-in imovie gratuit.
Cependant et suivant la même page citée précédemment :
(BTW, there is a free
cf/x turn clip iMovie plug-in, but it has some limitations: It doesn't properly work with interlaced input because also the interlacing lines are simply rotated and this doesn't look good on a TV! So you should use it only for progressive material or deinterlace the input. It can't rotate the material without cropping and it doesn't preserve the correct aspect ratio when rotating rectangular pixels).
