Vegas 10 won’t play my AVI file
Hi, I know this has come up a few times in the past but I think I have a slight variation on the theme.
I create an AVI File by writing a sequence of png files (as bitmaps). This all works very well, Windows Media player can play it and Expression Encoder can read it and convert it a wmv file (which Vegas can Play, but …). I can add the media to the project list but Vegas will not play it, not in the trimmer, on the timeline or as rendered (to another avi file). Vegas just shows the first frame for the duration of the event. GSpot says CVID(_RGB) and BI_RGB Raw Bitmap (no codec required). Which sounds about right as it was just raw bitmaps.
Any ideas why Vegas 10 Pro (x64) W7 would not like to play this? or any ideas where further information might be found? As you can see I aleady have a part solution but the AVI file can preserve the transparency in the clip.
thanks

All of this, and more, can be done in Vegas. Why fight with an intermediate file? Just do the whole process in Vegas.

If the PNG files are numbered sequentially, just load them into Vegas as an image sequence.

thanks Bob and Stephen, alas I’ve misled you slightly. The png files are created on-the-fly, saved to a png fle, added to the AVI file as a frame and then thrown away. It is an animation. So for 15 secs at 24 fps, that’s quite a lot to add as pictures to the timeline.

What does “created on the fly” mean?
I’ve had animators give me (and done myself) animations that are much longer than yours.
I always use the image sequence option that Steve mentioned as it works like a charm 🙂 -
Mike, in this case the animation is a Wpf/SilverLight animation that is stopped 24 times a second and a “snapshot” is taken and written to the png file. Each snapshot is then “appended” to the avi file (using an api). It would be the easiest thing to keep every frame and name them in some way that gives the order.
what would be the workflow to add them to the timeline?
thanks

Dave, that’s a strange of doing things but you work with what you have I guess 🙂
Make sure all the images are in the same folder and are properly sequentially numbered (i.e. 001-image.png, 002-image.png, 003-image.png, etc.).
This numbering scheme will work for up to 999 images. If you have more or less, add more or less leading zeros.
File – Import, browse to the folder where these are located, click on the first image, click the Open Still Image Sequence box at the bottom left of this window and make sure the range covers all your images, click Open, make any desired changes in the Properties box that comes up and click OK.
Your sequence will now be sitting in the Project Media tab ready to be dragged to your timeline.
Good luck with it. -
This is how I do time-lapse.
Here is a stage build that I did a few years ago consisting of 9,540 still images. This is the whole musical from set construction, rehearsal, performance and strike – in about 5-minutes.
