Frame image Scaling in Adobe CS6
- I think I read on various webpages that downscaling and encoding within Encore should be avoided.
- e.g. http://lacolorpros.com/blog/?10176-Adobe-Premiere-Pro-and-Encore-Outputing-DVD-and-BluRay-Workflow contains an article recommending encoding e.g. via Adobe Media Encoder first, then using Encore to create the DVD file-structure etc. to a folder, then subsequently using a 3rd party app such as ImgBurn to burn to an actual DVD or Blu-Ray Disk (BD).

- CS6 CUDA-Based Scaling is Sophisticated/High-Quality:
- Adobe Media Player in CS6 has sophisticated CUDA-based scaling algorithms that go beyond its non-CUDA-based ones.
- They are so good that they are said to be broadly equivalent to AviSynth-HD2SD
- But the CUDA-based algorithms only come into play when AME is encoding direct from a Premiere project (regardless of whether that project is open).
- They do not happen when encoding either a plain media (e.g. video) file or an After Effects (AE) Composition (Comp).
- HD to SD Conversion:
- HD frame (hence sensor and screen) aspect (ratio) is squarer than PAL-SD-Wide.
- Hence to avoid distortion, one can either:
- Crop the HD top and bottom (the most pragmatic solution, but then bear in mind effects on “Safe” regions)
- “Pillarbox” the HD within the SD frame, i.e. pad the HD image’s left and right margins, typically with black.
