    Hey guys!

    I have recently been trying to compile a few videos and am having trouble trying the process a section of the video. I have been following the guide on the GoPro forums (tutorial-exporting-with-vegas-for-vimeo-hd-and-youtube-t472.html) and this was exactly what I was after for my timelapse videos (see my link http://www.youtube.com/user/Squidald and let me know what you think). But when I have come to render some videos I took, I am getting the 2 black lines to the left and right of the video. I would prefer the render video to be full screen instead of letter box if possible.

    The other issue I had is I have tried to make a kind of track and zoom as I was filming a friend of mine but was moving at the same time so it requires the footage to zoom and follow him. When the video is rendered I noticed the lines would appear and disappear.

    Anything you guys can suggest?

    If it helps I would mainly just like to able to render the video at fullscreen, the zooming and tracking can wait!

  3. "fullscreen" has different meanings. It can indicate 4:3 aspect ratio content. So in a 16:9 display like youtube , it will be pillarboxed (black bars to the left & right). In this context it means "fullscreen" 4:3 vs. "widescreen" 16:9

    "fullscreen" can also mean expanding the display to the maximum of the display panel. In this case it would depend on your monitor aspect ratio whether or not you get bars

    You don't have any black bars at the small youtube display on your 1st video, which indicates your video is 16:9 (you probably exported a 1920x1080 video) . So if you do not have a 16:9 display panel, when you expand to full screen you will get black bars , otherwise image will be distorted

    Which example had pillarboxing or letterboxing? and what are your display panel characteristics ? What were your source file characteristics, project settings , render settings ?

    I am after a simlar outcome to the timelapse videos when fullscreen is selected, or like GoPro have on their youtube channel (http://youtu.be/GUEZCxBcM78?hd=1).

    I think the issue I am having is the properties between the photos used for the time lapse and the videos are different. Click image for larger version

    These are the project settings I am using to process the video.

    And these are the render settings I am using, these are also what I used for the timelapse videos.

    I have tried to stretch to letter box size but it alters the video and everything is squeezed and look silly.

  5. But what kind of monitor resolution are you using ? If you have a 16:9 monitor, the footage for the go pro demo will fit 100% perfect. They resized that video to 1280x720 which is exactly 16:9 AR . On anything other than a 16:9 monitor, you will get black bars

    If your source videos are 1280x960 with square pixels, you will NEVER get it to fit in a 16:9 window without black bars without cropping or distorting the image

    Your export settings don't match your project settings, you are exporting 1440x1080 with PAR of 1.33 (non square pixels). On youtube this won't look right either

    Post mediainfo view=>text of the source files copy & paste back here

    That's because you moved the crop box over the edge.

    There are several techniques for zooming and following within a video. Here's one of mine: http://www.youtube.com/watch?v=Sv2rgj0pxO0&. This was shot with a GoPro too.

    You have to use a smaller crop box.

  9. As budwzr says, your source files are 1280x960 4:3 aspect ratio (square pixels)

    The youtube display is 16:9, as is your monitor

    You're trying to fit a 4:3 "box" in a 16:9 "rectangle" , so you will ALWAYS get pillarboxing

    The only way to avoid this (without distortion) is to crop off 240 pixels: 120 from the top, 120 from the bottom . Because (960-720)/2 =120

    When you export, use 1280x720 settings, that is a perfect 16:9 display. That's probably what the go pro demo used.

    To add on to what PDR is saying, think of your desired video render as a 16 X 9 picture frame, and you want to put a 4 X 3 picture in it.

    You either enlarge the picture, and crop off some of the top and bottom, OR, you have to use a matte.

    The GoPro's still image is WAY oversized, so when you crop, you're not losing any detail. Like if you crop a square paper photo with scissors. What remains is still full detail, even if you zoom in on it.

    Not to belabor the subject, but if you use "Track Motion" instead of pan/crop, and lock the AR to 16:9, you can zoom and pan much easier, and the keyframe points will be visible on the timeline so you can get the timing more accurate.

    Poisondeathray and budwzr sorry for wasting your time, I didnt realise it would as simple as cropping the video by 240 pixels, just tried it and is exactly what I wanted! Now to give the track motion a go!
