VirtualDub-1.10.4 x86

I loaded a image sequence:

File -> Open video file -> Image sequence (the pictures are .jpg)

VD loads the image sequence and shows it correctly.

then i saved it as an avi video:

File -> Save as AVI

Windows Media Player crashes when i try to open the video file and VLC Media player shows a tilted video where the bottom right corner is cutted off and shown on the top left corner

i am kind of a newby in creating and editing video files... so if this is a stupid post i am sorry but any advice would be helpful to me

Usually:
The width isn't a multiple of 4
Most modern codecs require this as a minimum requirement - some may need 8 though
The height's usually need at least a multiple of 2

Two ways to fix it, both by adding filters to modify the size of the video
(On the video menu->filters>then click add for a list of filters to add)

1) Crop off the edges to make it the right size
Add a null filter, then click the crop button
In the new dialog, crop off the edges to make the width and height a multiple of 8
You might need a calculator to work that out :-)

2) Resize the video to the nearest right size
Add a resize filter, then click the configure button
In the new dialog box:
At the top click the 'relative (%)' dot
In the two boxes to the right of that type in 100 x100 (so it's the same size as the original)
At the bottom right'ish click on the 'multiples of 4' dot


Then click OK until you're back at the main virtualdub screen
Now save your avi

(If the is still slanted on playback, try a multiple of 8, then 16)

hi

thank you very much for your quick help

you were perfectly right... the size of the images was 301x301 pixels... i tried your solution 2 and it worked

i also recreated the pictures with 320x320 pixels and it worked without any filters

so again... thank you very much
