[Shandeep Gurupada] “I have a Sony HDR CX190E HD video camera… But it records video in 1080i 50… in Sony Vegas, I set the project settings as Interpolate frames and 50 FPS progressive output.”
Your camera shoots 1920×1080 at 25 frames per second not 50. That little “i” stands for “interlaced” which means 50 interlaced “fields” that make up 25 full frames. You should not set anything to 50 fps because you have no source that’s compatible with 50 fps.
Your project should use the HD 1080-50i (1920×1080, 25.000 fps) template and set your Deinterlace Method to Blend Fields. Only if you have a lot of fast movement should you use Interpolate Fields. The bluring might have been caused by using 50 fps which was blending your 25 frames to make new ones so I would start back with Blend Fields at 25 fps and see how it looks first.
[Shandeep Gurupada] “In this situation, do you think I’ll get better (or same) video quality if I render at 720p 50 fps output instead of 1080p 50fps for a given bitrate (I render at 4-6 Mbps to fit 1+ hour of recording into a DVD.)”
DVD’s do not support HD video. You should render using MainConcept MPEG2 with the DVD Architect PAL Widescreen video stream template for video and Dolby Digital AC3 Pro for audio.
