Using Camtasia, I captured a short screen cast with dimensions 853 (w) x 480 (h).
After importing the .camrec file in Camtasia studio I use "recording dimensions" everywhere.
Then I produce the file:
- Custom production settings
- MP4 / FLV / SWF
- No Controls / MP4 / 853x480 (Editing dimensions)
- the rest all default settings
After production is complete, the Production Results dialog tells me :
- Video Dimensions : 853 x 480
- Total Dimensions : 853 x 480
When placing the movie on our website, a black vertical line appears at the right of the video (video is mainly white and the web page background too). Closer inspection reveals that the MP4 file that was created is not 853 pixels wide but 854 pixels wide. Height is ok at 480 pixels.
The black line is two pixels wide, I assume one pixel is caused by the fact that the video is one pixel too wide. There appears no horizontal offset to the left, it seems that the right most column of pixels of the original is turned black, when I compare to the original.
I verified the dimensions of the avi in the camrec file: 853 x 480.
What is causing the output dimensions to go wrong and the black line to appear in the video and how can I avoid it?
Thanks in advance,
