Video Looses Quality After Export - Gets Blurry & Pixelated - Why?
I am using Hitfilm Express for over 2 years now and the problem I am going to describe never happened before until a few days ago. Nothing has changed on my setting or on my computer. Still the same as usual. Suddenly the videos are loosing quality after the export. Not the whole video though, always just a few seconds here and there within a 15-20 minutes video. The video is pixelated & blurry then. Looks like when you are watching YouTube on the lowest quality, liken when you have a super slow internet connection. (See attached screenshot)
This error occurs a few times in each video now, always a few seconds. The original video file does not have this problem and also when I edit the video inside hitfilm you don't see it pixelated. It only occurs after the export.
To export I am using the Youtube 1080 preset, 30 fps. Like I said before I havent changed anything, neither on my camera nor on the settings within Hiftilm or on my computer but suddenly every time I export a video, there are always a few seconds within the video that look very low quality.
I already re-installed Hitfilm new, installed the newest driver for my graphic card, cleared space on my laptop (free space is over 30GB now) and nothing works. Does someone has an idea how to fix this problem?
Intel Core i5 7200U 2.5 GHz
8GB DDR 4
NVIDIA GeForce 940MX
(Not the best to edit, but no problems with this system for the past 2 years)
Thanks in advance for any help :)
