Bad quality after render

[svens82]

Hi,

I created a short clip in Blender and finished it in Premiere Pro. But the result, after render, is not the same as shown in the Premiere Pro Preview. Left picture is after Render and right one the preview in Premiere Pro. The wall in the background looks so pixelated. Later in the clip, the table looks also pixelated in some scenes.

But why is the result wors than the preview?

Blender (images) and Premiere Pro are 25 fps and 1920x1080

Render Preset: Match Source - Adaptive High Bitrate

Are you rendering a high quality image sequence from Blender?  

[svens82]

The images are HD (1920x1080)

That's just the frame size.

What is the file format and compression type?

Or... are you rendering a PNG image sequence at either 8 bits per channel or 16 bits per channel as recommended in the Blender user guide "if you intend on-screen output or encoding into multiple video formats."

Blender Manual > Supported Graphics Formats

Ah, sorry.

It's 8 bit PNG (RGBA)

Compression: 15%

That should yield pretty good results.

Try using "Match Source - High Bitrate" instead of "Match Source - Adapative High Bitrate".

Also, try exporting a second PNG pass where there is no compression.

If you decide you want to try a different encoder, Shutter Encoder is donationware with several options for MP4.

Sorry for my late responce.

It also does not work. I changed the settings from "Adapative High Bitrate" to "High Bitrate" but it is still the same bad quality.

I haven't ried to change the compression settings in Blender. In my opinion, not the PNG's are the problem, the quality is perfect. Premiere Pro is the problem. Why do I get a wors quality after export than in the preview. I had a similar problem in the past

It was closed by an admin, but my problem is still the same. Maybe it has to to with...?!
