HDV 1080I to SD DVD


Until recently I hadn’t had to make a high quality DVD which had been shot on HDV. This hasn’t been an easy time working out the best workflow.

Footage shot on a Sony z1 at 1080 50i
Captured as HDV
Edited as HDV with rendering set to proress in final cup pro 6 using a late 08 macbook pro.

Initially I was doing the following workflow, completing the edit rendering the time line exporting a self contained quick time file using compressor to make the DVD authoring files.


The issue I was having was all the video on v2 or higher in fcp was showing artifacting that looked like it was over sharpened, and had aliasing when the final SD DVD was played. I’m making the assumption that there’s some issue with the way video is rendered on tracks 2 and above and must have something to do with the long GOP structure of HDV? Or it’s the mpeg 2 compression to mpeg 2 compression?.

I’m now using the following workflow.


Film capture and edit in HDV. When the edit is complete select the files in the time line then go file>export>quick time conversion.


Select proress and check interlace.


Once the file has been completed go to compressor and render the authoring files and your DVD should look a lot better!.

This method is the same as the one on ken stone web site except I check the interlace box. I have tried it with and with out and it dose make a difference!

Just in case its me I’m going to look into the settings of compressor!.
