Image Quality

Question

I have tried using uncompressed and compressed video files (3D animation) but after encoding in Toast, the image quality drops unacceptablly - TEXT screens are absolutely terrible.

 

Using H264 or MPEG-4 codecs, I start out with great image quality but even though I turn off "re-encode" in Toast it still sems to be adding another layer of compression and degrades the quality regardless of file size (the starting video file size - compressed - is only 1.7 GB so there's no need for Toast to compress any further to fit on a DVD disc).

 

Ideas?

If you want the result to be a video DVD capable of playing on standard DVD players then the video must be encoded as MPEG 2. That's what Toast does when you choose the video DVD format. If you go to the Custom Encoder window you can increase the average and maximum bit rates as well as mark the Half-PEL box to increase quality.

I've had the same experience with Toast - perfect quality 640x480 H264 (actually AppleTV standard) - gets re-encoded by Toast and looks about a quarter of the original resolution. Text looks particularly poor with very visible jaggies.

 

I've burnt the same MP4 files using VisualHub and the quality is extremely good so I don't understand why a premium product such as Toast should produce such awful quality.

 

Anyone having better luck burning AppleTV files with Toast?
