    Hi
    I have try to change a file that I have recording with a DV camera to another screen size without change the sound and the movie. It is like a fake widescreen so the screen is wrong 720x576 is going to be 720x480.

    I did try with mencoder but I can't the right commander line for it.

    mencoder -oac copy -ovc copy -vf scale=720:480 -idx -o finalfile.avi capture001.dv

  2. was the DV camera set to widescreen when the video was recorded? if so the 720x576 image is using non-square pixels and everything will look tall and skinny if viewed as 4:3. change the aspect ratio of whatever player you are using to view it to 16/9. for square pixels formats the video should be re-sized to 1024x576.

    yes the camera aws set to widesscreen but when I capture to the harddrive it show tall and skinny.

    I like to change the size before I start to edit so I dont need to change the player to something else.

    ohh I have to use 1024x576 and not 720x480. Good then I know that.

  4. for DVavi it can only be 720x576 if PAL. both the 4:3 and 16x9 are recorded at the same pixel size. you can't change that. you will have to convert to a different codec if you want to edit at the square pixel widescreen size of 1024x576. for the best conservation of video quality use a lossless intermediate codec like huffyuv or lagarith.

    you haven't said what the final format is you are looking to produce. if it's dvd i'd just edit in DVavi and make sure to render to widescreen mpeg-2.

    Your DV editor should handle this properly if you flag the source as "wide" 16x9. This is all standard.

    You lose quality when you convert. Tell your editor the project is a widescreen project and that the video is widescreen and it should be OK. Even if it looks stretched in the editor preview, ignore it and when you output, output as widescreen. Resizing and re-encoding before editing is a waste of time in this instance.

  8. ed and guns - i'm not sure he has a video "editing" program. he was trying to resize the DV with mencoder. if he said he had vegas or something like it, i would go a different route too.

    I read it that he was trying to use mencoder to resize to 1:1 widescreen to make the pictures look correct in his editor. I could be wrong though . . .

    If you tell vegas to it is a widescreen project of whatever format you have shot in, and also tell it to show you the correct aspect ratio in the preview, you will have no problems.

    It shouldn't be a matter of trying, it is the way to do it. It is the way the rest of use do it, and without having any problems with the shape of the video. Any resizing and re-encoding beforehand is needless, time consuming and damaging to the video.

    Any DVD player (software or hardware) expects 720x480 horizontally squashed video for wide format.

    Or 720x576 for PAL...

  15. errr. incomplete info.

    in vegas. import one of your original DVavi files into "project media". right click on it, select properties. down near the bottom click on the down arrow next to "pixel aspect ratio". select 1.4568 (PAL DV Widescreen). click ok. your video will now display as widescreen in the editor.

    do that for all widescreen DVavi files when you import them into vegas.

    Vegas is a little strange to create a movie

    After minidv2dvd tips that I can go in to the properties and change so I can get my clip in widescreen it make it nice to see when I edit the movie.

    But when I start to create a DV PAL Widescreen I see it create movie in wrong size.
    After I have edit the AVI to 720x480 it show big fat line on the left and right of the finnish movie.

    I have get it to work when I do it in DV NTSC Widescreen everything look nice.

    And when I trying to create a MPEG file in Vegas it dont have any size in 720x480


    But so far so good

  17. PAL DVavi can only be 720x576, nothing else. don't crop it, and make sure all the widescreen settings are correct for rendering, including the check mark in - stretch video to fill frame(do not letterbox).
