Shoot HD or SD?
on Mar 17, 2011 at 5:48:57 pm

Hey Gang!

I shoot and edit a 1/2 hour weekly show. Tv station takes a beta SP tape but the producer needs the content for his website as well. For this reason i shoot in HD. I have HVX-200 on which i shoot 1080i60i & on T2i i shoot 1080p30. Most of the time i am intercutting between these two cameras.

I edit this all in a pro res(1920X1080) sequence. T2i footage is all transcoded to pro res 422. For tape delivery, I downcovert realtime through Kona Lhi. For web use, i just make a H.264.

I watched this week's episode & it did not look all that crisp to me. It made me wonder if i am doing something wrong in my editing setup or should i not shoot in HD & just stick with SD.

I would stick to your HD workflow. You might be able to improve on the web version by enabling frame controls in Compressor and setting resize to the best setting and deinterlace so your 60i ends up progressive for the web.

There have been lots of posts about how to get the best out of Compressor so a search of the forum should help with that.

you didnt say if it was unsharp on one format or the other (or both).

I find that Beta SP does look less sharp than more modern delivery formats. Getting tapes in on Beta SP - they always look much softer and noisier than Digibeta. It may just be that you are used to seeing clean crisp digital video and when seeing the beta sp back, its limitations are more obvious.

Michaels right about learning your compression tools and sticking to your HD workflow.

I was told an interesting fact a while back - The better your hd image, the smaller and cleaner your compressed image will be. In essence, the more noise in an image, the more data the compressor will try to retain, thus bumping up the file size, and noise in your web output. He went on to say that was one reason many people are shooting web video on cameras like the Red.

Did you "Render in High Precision"?

[Sohrab Sandhu] "should i not shoot in HD & just stick with SD."
Shooting HD when going SD or Web has advantages (reframing, panning, etc) but downscaling is always an issue, and 1080 may end up complicating things.
I shoot 720.

Yes, its high precision rendering.

When i say video is not crisp, by that i mean that beta tape version being run by the tv station. The content for web looks great. I don't have any issues with the web content. If anybody is interested in taking a look, here is the link.

For downcoversion to beta tape, i was using centerpunch, do you think letterbox or anamorphic is a better option?

That may be one of the less valid reference.
what you need is to make sure that your program looks well on a pro monitor and don't forget to put some proper Color Bars in case the guys of the TV station care about quality and check everything before going to air.

This is up to your client specs. I think big networks do not accepts LetterBoxed. LetterBoxed reduces definition.
