Zoom in with pan and crop is blurry SD compared to HD
When I zoom in with pan and crop to a SD (853X480) sized frame using video that is HD (1920X1080). When rendering to a DVD (widescreen 720X480) and then playing, the zoom part is not as sharp and a little blurry compared to the native HD part. I would think the SD cropped part should be just as sharp as the HD when rendered down to the SD lower resolution. I have tried the sharpen FX. How can I make it the same quality?

Cropped and at the same delivery size? Why? You’re spreading the same amount of pixels over a bigger area? Meaning you’ve zoomed in on an area of SD and comparing it to HD. Unless I’ve got the wrong end stick?

Shoot in HD.

Graham, I thought the same thing at first so I and to read it twice. What Cody is doing is shooting HD, then zooming in to SD Widescreen resolution and rendering SD Widescreen but the Zoomed HD footage looks more blurry than the HD footage that wasn’t zoomed.
Cody, make sure that you render with BEST quality. The default is GOOD, but this assumes that you are not resizing your video (which you are). Whenever you render HD to SD, you should set the render quality to BEST so that you get better bicubic resizing. See if that helps.
Also understand, that HD video resized to SD looks better than SD video because it started with more information. When you resize your SD video to SD, it no longer contains this additional information. You are now comparing ‘SD’ to ‘HD resized to SD’ and you will see a slight difference in quality.

Ah right John …. My apologies Zack, you DID say you were doing this to HD footage, I was wrongly thinking you were mixing SD into a HD and zooming in on that “SD” footage.
