What if the screenshot from the video taken by GoProom is blurry?July 26, 2020
There are several possible reasons why, from a video taken with an action camera, it is not possible to take a single thumbnail of the video that will represent that video.
I have one video taken with a GoPro camera. It’s a tandem parachute jump. The team processed the video and sent it in MP4 format; as far as I understand, he saw it at 60 FPS. How can I take a screenshot of the video? I’ve tried Photoshop, Lightroom and literally everything is blurry and blurry. Is there any other way, at least that the quality is OK?
A very precise description of the problem is important here. As far as can be read from the question, this is a recoded / processed video composed of recordings taken by GoProom, ie you do not have access to the original recordings, the original files made by GoPro’s camera.
If it is motion blur, therefore, the blur caused by movement, you can’t help yourself too much. Motion blur is a consequence of the relationship between the shutter speed and the speed of movement. Eventually, you can try to use the Smart Sharpen effect with the Remove: Motion Blur option in newer versions of Photoshop, for which there is a good tutorial on YouTube, at https://www.youtube.com/watch?v=US8yI3ymZEE.
Alternatively, you can look for some static frame. If the static frame is also blurred, then it is not a problem at all motion bluru, but then the problem is either in the recording itself or in that recoded file.
Problem with the recording
If the problem is in the recording itself – there is not much help here either. Maybe the lens was dirty, damp, damaged or whatever … You can get some sharpness by sharpening the image, which may be OK for thumbnail lower resolution, if necessary, but it all depends on the “nature of the blur”. We need an example of a problematic video thumbnail to see what you’re dealing with at all.
It should be taken into account that it does not matter which camera was recorded and whether it was recorded in 4K, 1080p or 720p, and framerate can affect the final quality because higher framerate requires shorter exposure time (faster shutter speed). Light conditions should also not be ignored – it does not matter whether it is shot under a sunny or cloudy sky or on the eve of sunset.
If the recording is well, correctly recorded, then the problem is in the processed, recoded file. It may have been used too low bitrate (for the codec with which the video is encoded) – for dynamic scenes at 60 FPS, a very high one is required bitrate, probably with two-pass coding, to keep individual thumbnails as sharp as in the original shot. When watching a video, this may not be so noticeable, but if you try to extract a single thumbnail, the encoding quality can very well have a significant impact.
Maybe the resolution is lowered, maybe the conversion was done improperly frameratea… Ask for the original files from which you want to extract thumbnails, or ask the person who has the original files to extract the desired thumbnails from the original files.
