Jaggies appearing after encode
on May 8, 2013 at 9:22:13 pm

This has been driving me nuts! Every time I bring a clip into Encore to burn to Blu-Ray, it results in jaggies -- mostly on text, diagonal lines, etc.

The field order is progressive all the way through. I'm using 1080 24p H264 encoding (also tried MPEG2), and the source looks great all the way up to burning the disc. I have tried multiple video files, different codecs, all the same result.

I've tried using Compressor, Adobe Media Encoder, and even Toast -- they all produce jaggies. Anyone have ideas?

Thanks greatly

Is your text moving or static? what is the bit depth of your original text files? What settings specifically are you using to encode.

Could be a number of things, text and straight lines are very hard to compress well so you need to massage your settings until you get something that looks acceptable.

A workflow tip would to just encode a 10 sec clip to use for adjusting your encoding settings. If you can upload a screen shot of your setting that might help.

Try to use the h.264 codec instead of the Mpeg2, you will get better results from that for sure. And play around with your Anti-Aliasing filters to reduce the Jaggies and use the Anti-aliasing settings in your post workflow, especially if the text is coming from photoshop, that will help reduce the Jaggies. You can also use a small amount of motion blur, and remember to render out your your text or video at the highest quality render settings.

Also make sure that the text is wide or bold enough to compress well, edges and details of small text can be problematic.

Hope that helps
