"When I watch the original files versus the final edit, the edit suffers from a dramatic loss in image quality over the original. The new edit appears to have less saturation and contrast and the overall picture seems less sharp." from an Adobe User.
As an Adobe user, I know you have a rough ride in editing videos of 4K resolution, especially when you finally manage to finish editing, but get quality-degraded videos after exporting. According to users review,quality degrading involves lower resolution, less saturation, contrast and sharpness, and image jerky. And this is what users can't stand most, so let's take a close look at this issue.
Adobe Premiere Pro is a professional video editor, and there are plenty of parameters and settings you need to pay attention to. If the output quality is different from what you expected, there must be something wrong with editing presets or exporting settings.
1. Sequence resolution is different from exporting resolution.
To edit different video materials freely, users incline to set sequences to edit clips separately. And if the sequence resolution differs from the output, like, lower than the final output, it will be first down scaled, and up scaled when exporting. In the process of changing resolution back and forth, it finally upscales the resolution from the lowered video, not the original 4K video, and thus results in bad quality after exporting.
2. The output video settings don't match the 4K source.
Adobe has default presets for exporting settings, so you'd better check the settings by yourself, whether the width, height, and frame rate are the same as the source video, in case that it down scales the 4K video to 1080p, 720p or other lower resolution.
3. The bitrate settings are not proper.
Bitrate is the number of megabits per second which decides how much data it processes per second. Different formats present different bitrate options. Rendering a high-resolution video needs a high bitrate to keep up with the information stored in the video frame. So quality loss occurs when you have a low bitrate to compress 4K videos.
Solution 1: Preset in Sequence Settings
Follow the instructions to match the sequence resolution to the output resolution:
Step 1. File> New> Sequence> Sequence Presets>Digital SLR>1080p 24
Step 2. Switch to Settings from Sequence Presets, and set Frame Size as 3840x2160.
Step 3. Hit OK to save sequence preset.
This method is to check and fix quality loss caused by sequence settings. If it doesn't help you out, please turn to the next solution.
Solution 2: Set Exporting Options
Step1. After editing, open File> Export> Media>Basic Video Settings. Set the width and height of the video to 3840 and 2160, and change the Frame Rate to 60. You can refer to the summary info in the upper place if you are not sure about the source frame size and frame rate.
Step 2. Choose VBR 2 pass in Bitrate Settings, and set the target bitrate to 40, and maximum to 60. If you are uploading a 4K video to YouTube, you have to set it much higher, because online video platforms will compress your video again.
Tips: If you mix videos of different resolution, like 4K, 1080p, 720p and others together, please select Use Maximum Render Quality to avoid quality degrading, saturation and contrast losing.
Solution 3: Keep 4K Resolution Throughout the Process
Adobe Premiere Pro is a powerful and comprehensive video editor when editing 4K videos, but it changes the video resolution to meet to different editing requirement, so it is hard to handle the resolution properly.
