I have a project with 2 tapes shot HDV 1080i 50 by mistake and 4 tapes shot HDV 1080i 60 which is the intended format. Can I use compressor to recompress the 1080i 50 to 1080i 60. Has anyone tried this and how clean is the compression. This is not a high profile project just a simple 3:00 promotional DVD and a few :30 web spots. Considering the usage I would prefer not to use an expensive external box conversion.
