DaVinci lagging so much with .PNG graphics

PostThu Jul 22, 2021 8:12 am

Hi,

I made simple dance video with just 2 cuts (3 clips).
Recorded with BMPCC 6k with 6k BRAW format.

I added little watermark graphic in the corner of video in .PNG format and after stretching this graphic on whole video (1:30 min) all the playback and render slowed down like 900%. I can't playback because it's 0-0.5 FPS. Render slowed down from 0:56 sec to 3 hours (JUST FROM ADDING SOME PNG GRAPHIC!).

iMac Big Sur 11.2.3
Retina 5k, 27-inch, Late 2014
4 Ghz Quad-Core Intel Core i7
RAM 16 GB 1600 Mhz DDR3
AMD Radeon R9 M290X 2GB

I know all the tips about making DaVinci working fast, so it's not the case.

Why PNG graphic slows down everything so much?

Thank you very much in advance!
Best Regards

What is the resolution of the graphic?

Ohhh just checked.

12548x12548

That's the case. I didn't bother with it because I saw that the file was only 900kb, but still resolution plays key role here.

Thank you!
