SD or HDV

Toady I noticed some quality resolution after shooting HDV then SD footages with my A1, the SD 3:4 looks squeezed on my TV , I'm viewing those footages via component cable with 1080p tv .
Why would someone need to downconvert from Hdv to SD since the camera offers both options
I'm confused:bath:

HDV is tough to edit so you can do an SD cut of the film but still have the HD raw footage if you want to go HD later.

I've heard that from several sources now, "HDV is tough to edit." What problems arise when editing in HDV that don't happen with standard def?

Thanks in advance for answers.

The quality is better to begin with HD, so when you down convert to SD and when you blow the image up on an SD time line, the image stays together.

On what? I see this reeated a lot on the web, but no one has ever explained exactly what is tough about it! Please explain what you mean by "HDV is tough to edit" !

I know it's group based frames etc, but I am using FCP 6 and FCE 3.5 and have absolutely ZERO problems editing HDV !!

I just wrapped up a 30 minutes film shot in HDV and I ran into quite a bit of problems in post, most of them having to do with the amount of processing power required to edit. It's the nature of the interframe compression. I have an AMD X2 4800 processor with 8800 GT graphic card and I still can't do smooth preview with full titles, transition and CC on Premiere Pro 2.0. You may not have a problem working with a 5-10 minutes project but when you have upward of six hours of videos to edit, that's a lot of strain on the computer. I can't tell you how many time Premiere crashed on me because it couldn't handle the multiple video streams. The render time is quite long (six hours to render 30 minutes).

I couldn't even think of doing any extensive special FX with HDV because it runs too slow on After Effects.

This project is probably the longest project that I've done with HDV and it's definitely tough. If I were to do say, a feature, then I would consider investing in something like Cineform an absolute must.
 
If you use Cineform or Raylight to convert the M2T files to avi first you retain the quality of the HDV and you can edit almost as easy as SD. If you are using a 2.4 + ghz machine with a minimum of 1gb or more of ram you shoul have no problem. Real time play back in the preview monitor is not possible like with SD. I undersatnd that Vegas 8 does not require the rendering of long GOP clips when adding affects.

I saw one of the cameraman of this TV station shotting with the XL-H1 , since it has HD-SDI and SD-SDI output, dose that mean no down convert is required for SD footages in this camera ?

Thanks. I have indeed noticed that for some things, real time playback is a problem, and rendering is required, but then I see this with other HD files too and not just HDV.
 
What about ProRes? That comes with the new Final Cut and shouldn't it solve the processing problem issue?
