Poor PIP quality

Hi Marious -

I've played around with this a few times and I'm struggling to get PDR13 to generate the difference in picture quality you posted with your "err-pd" screen shot, which clearly showed degradation in PQ.

Part of the image below is your original "hd-mac.png". Part of it is from a produced file from PDR13 - MPEG-4 1280x720 @ 16MBps Quality Mode. Can you tell where one stops & the other starts? Can you tell which is which? Is one side better than the other? (This is not a trick)



Attached is another combination screenshot. 1 = original, 2 = PDR13 produced (Tony) 3 = Adobe Premiere... 4 = PDR13 produced (Marious). It may be my old eyes, but I'm having trouble spotting a significant difference in PQ.

See what you think laughing

Cheers - Tony

Really appreciate your help guys!



Ynotfish - it looks great, as you saw in my example I am not picky here, it is bad quality, not just 1% off



Is it possible that it is Windows 8 doing it? Maybe will put a trial on Windows 7 or sth?



Or am I doing sth stupid that causes it.



Please find a clip showing how I created this project

Quote: PlaySound, is pd13.jpg the one you produced using PD13? What is mac.jpg pls?


Once I created the video similar to yours, I used the 2 mac-address.png pictures on white background..

I added this video and your hd-mac.mp4 in the timeline.

Extracts one picture of each, (pd13.jpg) rendering here (mac.jpg) your video.

Note: Now did the way the test you have shown in the video and got better results almost the same as HD-mac.mp4 video.

That's why I always ask to post the project here.

As I am doing now as an example.

It seems to me that photo extracted by MPClassic is better than extracted by PD13 here, but still sees little difference between MAC and PD.

PlaySound, thanks for that!
The quality of your PD output is unacceptable for me, it is all blurred. It is better than I got but still bad if you compare to the source file... It has to be sharp, I need it for text and screenshots with lots of text


How did ynotfish receive almost a perfect PIP?

BTW. Just tried a trial version on Win7, exported as mpeg (trial does not allow to save as 720p mp4) - still all blurred

This is fascinating! I agree with Marious79: the blurriness is apparent in the version done by PlaySound (although see note below*).

However, in the version done by ynotfish, there is no difference at all that I can see.

Mr Ynotfish, can you describe how you did it?

* PlaySound made a small mistake by using JPEG for the snapshot, which is why those compression artefacts are clearly visible. JPEG is fantastic for photos, but not suitable for non-photographic material like diagrams, etc. They should always be GIF or PNG.

Yes I saved snapshot in PNG but I saw no difference in this case in this case.


Windows 7-64 this updated video card as well.


I am puzzled why can not the same quality obtained by ynotfish.


It would be good that other members also verify that you have the same problem, download and run the project I posted is fast.

Guys could you check the clip I uploaded to check if you design your PIP in the same way pls?

Hi Marious, PlaySound, Thackery et al -

Thanks for the "pd-doing" video. It contains a step I'd try to avoid if resolution is critical - when you resized the ,png at about the 20 - 30 second mark.

Here's exactly what I did - https://youtu.be/2yzV98dyT8I - at no time is your original "mac-address" .png file resized. It keeps its original resolution.

By the way, here's the answer to the puzzle I posted above...



Thackery - I'd have to politely disagree with you about using GIF format for snapshots. If you have a look at the attached image, which is a combination of 4 PDR snapshots zoomed to 800%, you'll see why. It's when you zoom in like that, you get to see what's really there (and what's not!).

Cheers - Tony

ynotfish, great work but what you did was not PIP really? My project involves a Full HD background png file and I will have to insert 720p clips.

I have no issues producing full resolution clips, images etc. in PD. The issue is when I insert sth smaller (PIP).

And I as I saw, PlaySound did not receive sharp outputs either.


Just to complain a bit - I am disappointed as I've opened two tickets with CL and they have ignored me since.... it's been a week now.

In my opinion, if we cannot produce a perfect PIP quality output, it should be reported back to them.

BTW - to be fair - Corel X6 that I use does exactly the same thing - it is blurry. However, Adobe and Sony produce a 100% perfect output.

Marious -

I pasted the "mac address" graphic onto white to replicate what you had done. I would typically insert in onto a blank transparent canvas the same resolution as my intended output. Attached examples. The point of that is that there is NO resizing.

Well - I'd refer to it as PiP because it's a picture in a picture. laughing

I can't see that this is an issue peculiar to PDR. I've repeated the process with other NLEs with similar results (the difference is down to what codec is used in production).

You're right - Tech Support should be more "supportive".

Cheers - Tony

ynotfish, thanks!

a transparent png would work... but... what do you suggest for my project?
I will have a png background image 1920x1080 and need to insert video clips inside 1280x720

Hard to say without knowing the exact contents of the project.

Basically, if you're producing to 1920x1080 insert your PiPs on transparent 1920x1080 canvases... but if you post a screen shot of your project workspace, with annotations about what is what, members would be able to advise.

ynotfish, it is a way around but do not like that one of the most popular applications in the world cannot render good quality standard PIP videos.
