Some Cropping help??

Brolli12 · Post by **Brolli12** » Sat Jul 12, 2003 12:54 pm

Ok Here's the deal:
For some reason ( I don't care why), my DVD adds some annoying lines (about 4 pixels wide) on top and on the right of the picture. Of course I don't want that in my brand new AMV so I try to crop it.( I use V.Dub for this). But for some reason I keep getting an error massage when I try to save the avi file. (The video used is the raw I get form premiere using Huffyuv). Sometimes I don't get an error but the video I get is screwed up playing diagonically(I mean like Italics In a font ).
I am very new to cropping so any help would be welcome!!
Thanks in advance

Ok, it would be nice if you would please include the error message you're getting.

But also usually with video compression there are some resolution restriction. Such as the video has to be a multiple of some such number.

I believe for huffYUV, you need to make sure that both the height and width are even numbers.This is just from fooling around right now. It may be different.

If you're saving it as a DivX or MPEG1 file, then you need to make sure it's divisable by 16 for DivX or 8 by MPEG1.

You can accomplish this by cropping, then resizing up or down to a proper resolution. To find proper resolutions you can use <a href="http://kproject.home.comcast.net/Misato ... -Aspect</a>, instead of inputing the actual height/width of your video, enter in the aspect ratio of your anime source. It's either 4:3 or 16:9, depending on if it's anamorphic or not.

I'll just post some here anyways

in case you're feeling lazy:

Resolution: 640x360 Aspect Ratio: 16:9 / 1.77777777777778:1
The following resolutions are valid:

256x144 512x288 768x432 1024x576 1280x720 1536x864 1792x1008 2048x1152 2304x1296 2560x1440 2816x1584 3072x1728
--------
Resolution: 640x480 Aspect Ratio: 4:3 / 1.33333333333333:1
The following resolutions are valid:

64x48 128x96 192x144 256x192 320x240 384x288 448x336 512x384 576x432 640x480 704x528 768x576 832x624 896x672 960x720 1024x768 1088x816 1152x864 1216x912 1280x960 1344x1008 1408x1056 1472x1104 1536x1152 1600x1200 1664x1248 1728x1296 1792x1344 1856x1392 1920x1440 1984x1488 2048x1536 2112x1584 2176x1632

So crop your footage, then resize it to the closest resolution you want to distribute your video in, from the list above.

this must be it for the error because it is about image size when I try to crop and compress with X-vid at the same time!
The funny part is That I hade these disturbing lines with "Nightmare" one of my vids ) last time but didn't have these problems cropping following the same steps!
Anyways thanks a bunch!!!

If anyone else knows about something refering to V.Dub or another program, without having to resize please share the thoughts.
Thanks

What?

Just add a Null Transform, cropp off the edges. Add the Resize filter after that, set it to one of the above mentioned resolutions.

For 4:3(which is most likely what you have). Set it to either 512x384 or 448x336.

For 16:9, set it to 640x360. Make sure you set the filter mode to BiCubic or Lanscoz resize.

Hit OK. Then all should be well.

Not true. Dimensions for DivX files must be a multiple of 2 in one direction and 4 in the other, or so Vdub told me.

Actually I did my cropping with null transform without calculating the multiples and then added a resize at 512x384.
Turned out pretty sweet!!!

Thanks
