Hi experts.
It's been years since I last used VD so kinda forgot most about it.
I'm trying to crop a video, but my result is very odd...
The video was recorded in WinUAE Amiga-emulator with Xvid MPEG-4 codec and PCM 44,100kHz, 16 bit stereo.
I'm using the filter Null Transform, and saving as segmented AVI
Here is how it looks after save

The colours are actually fine, don't know why they are not in the snapshot but the video is all warped.
How do I fix this?
Thanks |

Is the video a weird resolution? I sometimes have troubles with some decoders if it's like 1278x720 instead of 1280x720. Maybe try using FFInputDriver:

Yes it's the width of the video that's the problem
Best practice is to make sure you're cropping to a multiple of 8 for the width and 4 for the height
Many decoders can use 4/2, but 8/4 covers practically all of them
PS
Newer ffmpeg versions than the above link are available in my sig or from the List Of Input Plugins page

The original size is 800x600. The FFInputDriver didn't help.
The cropped size is 573x343.
Trying to make it 8parts width x 4 parts hight 686x343, didn't help. Same result, only now in black and white.
Since you said it is a width/hight issue I figured 800x600 is 4:3 so scaling to 600x450 should be the same and that did the trick 
Now I have to fine tune a bit.
EDIT: forund this http://size43.com/jqueryVideoTool-4x3.html and ended up with 572x429.
Thanks for your input guys |

Instead of the Nulltransform filter you can better use the "Resize" filter.
It allows you to combine cropping AND resizing.
When you have select it, via Video > Filters... > Add... "Resize" > OK, you can set the
- New size to "Absolute" 640x480 (4:3) / 640x360 (16:9),
>> Please try to use these default sizes if possible. If not, then please use multiples of 4 or 8...
- Aspect ratio to "Disabled",
- Filter mode to "Lanczos",
- Framing options "Do not letterbox or crop",
- Codec-friendly sizing "Do not adjust" + OK.
This was the Configure... process for the Resize-filter.
Now, you can click the "Cropping..."-button, to crop unneeded pieces.
Click OK to confirm. |
