HTML5 PAL Scrolling Text, Flicker Issues

Postby automatical » 25 Mar 2017, 15:00

I'm currently working on a project that involves having a collection of scrolling text on the lower third of the video output.

We have spent a considerable amount of time trying to ensure that this text is as smooth as possible, but we still see some flickr on the edges of the text as it scrolls to the left.

Although what we have may be acceptable, I'm still hoping to produce the best quality output possible.

Is there anything that we may be able to do to improve this.

We are using:
* HTML5 Template
* Current Stable CasparCG

Apologies for the late response on this. Unfortunately out template requires our backend to exist (and push it data) to be able to run correctly.

We managed to diagnose and resolve the issues after some experimentation and investigation

For future reference - this issue down to 2 separate (but related) issues:

The font we were using was too fine for the interlaced output - I've updated this to use a more suitable font.

The SVG font was failing to load correctly.
