I am completely new to Photoshop. Can Photoshop be used to clean up video and to crop videos?
Yes, you can import a video into a timeline and work with as video layer, performing basic corrections (cropping, adjustment layers, effects, etc. The number of available corrections can be increased by converting video layer to a smart object) - this is will be applied to the entire video as a single object. It is also possible to split the video into separate frames and work with them as regular layers (this means that all Photoshop tools are available to you). After processing, you can export the video.
What do you mean by 'Clean up videos'? If you are asking about cropping out unwanted sections and rendering out to a new shorter video, then absolutely. You can also perform similar functions to those you might use on a still image.
Cropping videos might be problematic, as the finished video that you render out has fit the format you are using. A 1080P video is 1920 pixels wide and 1080 pixels high, so cropping your video will reduce that. You can choose to render out to a different format, like 720P, ans scale the cropped video to fit. This approach works best if the original is 4K so you can crop and scale to render out to 1080P which will still look sharp on a TV screen.
Cleaning up video could mean to fix interference, and Photoshop can't do that. Apps like Handbreak (which is free) might make a difference, but in my experience, it won't perfectly clean up poor quality video.
Does this help? If you need more, then the more information you give us, the better the reply that you'll get.
Good luck .
Yes, You can perform any task related to photoshop. You can also use some video editing apps which are very poplular in the market these days. Like kinemaster. But there is no replacement of photoshop.
Yes, Photoshop can be used for cleaning up images. Still, it's not typically designed for video editing, so it might be complex for video editing because it has professional tools that require some better understanding.
If you're on macOS, I'd recommend using iMovie to clean up and raise the image quality; the Enhance button in the toolbar works wonders with just one click.
Now for Windows users, I've had good experiences with Movavi, as it allows removing objects from the background with their AI tool, and the interface is super straightforward. If you need more options, you can [link removed by moderator] to find more alternatives.
