Corel USER to USER Web Board

Hi guys! (First of all, sorry for my english, is not my mother language and maybe I'll make some mistakes...)

I'm making my holiday video and I usually add some title showing the name of the place. The problem is when I export the project to a file, when the titles appears in screen the quality gets lower while the title is showing, showing some saw-teeth and blur, when the title dissappears automatically the quality increase to the original one. The original files are Interlaced, upper field first. I usually export with the option "same as first video clip" but I tried so many options, doubling the bitrate, changing fields order, mpeg optimizer, two pass encode... and the same happens.

The only way this doesn't happen is if I export changing upper lower first to frame based. The point is that if I do that, maybe there is a little loss of quality, right?

What can I do for not lose quality? I need necessary convert it to progressive with frame based option? Will I lose quality of the whole video with it?

I uploaded the snapshots to show you what I mean https://ibb.co/mbbseT

Hi vximo

And welcome to the forums

The saw tooth effect does seem to indicate an interlacing problem.

What are the properties of your original video file, right click a clip on the timeline and choose properties, what are they
Also tell us the Project Properties are they the same as the video properties.

What are you intending to make, if it’s a video for the internet then using Frame based / Progressive could be a better option.

Certainly Frame Based seems to produce better quality.

Does the jagged edges only show where the titles are being displayed or throughout the entire video?

There is a quality issue when using Smart Proxy files
If you have completed the editing then try removing the Proxy files before rendering.

Hi lata! Thank you for your welcome and reply!

The properties of the originl video file are
PAL (25fps) MPEG Transport-Stream files, 24bits 1920x1080 25fps
Upper Field First (HDMV-PAL), 16:9 H.264 Video
Video date rate variable (max 22000 kbps), audio data rate 256kbps

The project properties are the same as the video properties and the video is intended to be reproduced in TV and home projector theater, not internet.

The jagged edges are just shown while the titles appears on screan, when the title fade out the quality of the video increase to the original quality, it's like if you are watching a youtube video in 1080, suddenly the quality go down for a bit while charging and then get back to high quality.

---> I have made a test removing the Proxy files before rendering and the problem was fixed and the quality is perfect, I guess that was the problem!!

This is my first project in VS 2018, I've been using VS for years, since it was 'ulead videostudio' and never had that problem with titles. Don't worth the money of the upgrade... Not just this, also it seems like if this version was slower, when I click on the share button it takes ages to be ready, the program do not respond for a while (as I see in Task Manager) and about two or three minutes after it changes to the Share menu, and again when I want to change the output configuration, it freezes again for a while. Also, while editing, working in the timeline is a pain in the ass, very slow and lagged, I hope Corel fix this issues...

Thank you lata because removing the Smart Proxy files worked for me!
