Can't get video cropping to work in CS8.6

  • Question
  • Updated 3 years ago
I have videos that I want to crop. Let's say for example the video is 960x400 and I want to crop off the left and right 80 pixels (160 in total) leaving me with 800x400. So, I toggle crop mode on, get the blue border, adjust it to lose the left and right pixels and all looks good, and I toggle crop mode off. I then click Produce but instead of getting an 800x400 video, I'm left with a 960x400 video still but it has black in those left/right pixels instead of cropped content. I want the cropped size to be the output size, but I don't see anywhere showing me an option to do that. Imagine I didn't know it was 80 pixels I was cropping from each side, I'd have no idea that the output video should be exactly 800 pixels.

I just want to crop. It should be easy. It's not.

I'm currently having to export uncropped to avi, load into virtual dub (which needs avi), doing the simple crop and saving (automatically to the cropped size, because that's what apps do when you crop something).

set your editing dimensions to the desired output [cropped] size

What if I don't know what the desired output size is? I've got a video loaded up in CS right now where I've dragged all four sides inwards to remove the black borders that were all around the content. I've no idea what the size actually is, and CS isn't telling me. I'm looking for a button or menu item I can click to select "adjust output size to cropped size".

I really shouldn't have to take a screenshot and load it into photoshop and crop it to the visible video and then ask photoshop to tell me the size and then go back to CS and enter the size. CS knows the size.

Hello,

You know that your desired output is 800x400? Try that in the editing dimensions.

Timbre4's comment is on point

but you can easily check the post-crop video's dimensions by exporting a frame, and checking that image's dimension properties in Explorer

you could also un-dock the canvas, and, with the cropped video at full size, use Recorder's "select area to capture" function to measure the dimensions; then, set editing dimensions to those values

after you set editing dimensions to that size, do a custom production to MP4 with controller, then, you should be good to go

When you go to produce your video, set the output size to the 800 x 400 in order for the video to be the same size as the cropping

Thanks to all for their suggestions. The way I actually did it is to use Windows 7's "snipping tool" to take a screenshot which I loaded into an image editing program and found the dimensions there and entered them into CS as the new video size.

Half of my aim here was to report that it should be way simpler. If the following two were available it would almost be too easy:

1. Something showing the current crop-box dimensions in real time as you're moving the lines of the blue box in and out.
2. A button (while crop mode is active) to change the output dimensions to the cropped size which you can click before exiting crop mode.

Surely it can't be a rare use case to want to trim some pixels off of the edges of a video and not be sure what the size is now you've done that. After I'd done it, my current crop size was something like 813x369, so obviously I had to crop a bit more or less to get to even numbers.

Hi DeeDee,

Thanks for the feedback. This is an interesting process. Can you tell me what you were planning on doing with a video that is 813x369? Are you delivering it as-is? Using it in another video?

I should also advise you that sometimes producing a video (especially .mp4) at dimensions with odd numbers can cause slight quality loss, usually seen in text fuzziness. So if possible, try to edit videos with an even-numbered height and width canvas.

You missed the second half of the sentence where I said "so obviously I had to crop a bit more or less to get to even numbers" ;-)

That video wasn't going to be "delivered" to anyone, it was something that was given to me but had a green line on the right edge of the video, 4 or 5 black pixels on the left, 60something at the top and bottom, and had sections at the start and end that needed trimming. To get it to even numbers I had to trim 1 pixel more than I needed. The use case for this is that it's a video that will live on my computer and be "full-screened" to watch. It's not going to youtube, or dvd, or blu-ray, or to be delivered to anyone.

Ha, yep! Totally missed that. Sorry. Must have had jingle bells on the brain.

It does seem like a "crop canvas to media" function would help you there. Or at least something that tells you the dimensions of your newly cropped media. I could see the latter being helpful in other cases as well.

Thanks for posting your idea and issue. Sorry I couldn't be of more help.

you are correct in that this task should be much easier to accomplish

here is how to do it quickly using Recorder ...

if you have Snagit, here is another very fast way to do what you want ...

if you do not own Snagit, this technique may also work with TechSmith's free Jing capture tool ?

hope these can work for you
