Poor resolution and flickering of still image renders
I'm noting a very poor resolution of images that are rendered, even at high bitrates.
I'm also noting an odd flickering of rendered images.
My project is simple - a single image on the timeline, followed by a video clip, followed by an image.
This is the image I am using - Dropbox - original image
There are some oddities in the render. This is a screengrab from Window Media Player, showing the first frame. The quality of the image is as I would expect, no issue here.
After that, subsequent frames show a significant decrease in quality. This is even apparent in the scaled down images embedded into this post, note the artifacts in the shadows under the shelves.
You can show the same thing by pausing the Youtube video and rewinding to the first frame.
Then, if you playback the video render, you will note flickering of the still image in the render. This is a CBR render at 50mbps, 59.94 fps.
I tried the same render at VBR, 50mbps, 59.94fps
In the middle of the video there is a video clip. When transitioning from the still image to the video clip during playback, you will note the first frame of the video clip also suffers from the decrease in quality
Thereafter, subsequent video frames get an increase in quality (in particular pay attention to the detail on the center rock)
My export settings are as follows for CBR, VBR is as below both target and max bitrate set to 50:
Scale Mode: Keep Aspect Ratio
Frame Rate: 59.94
Aspect Ratio: Square Pixels
Bitrate: 50.000 mbps
