Downconvert

َQ: why/When would someone need to downconvert the A1 footages ?
In camera? Or in post? There's a lot of reason. Most computers can't run 1080p well, so I downconvert all my final HD output to 720p. Sometimes there were stuff shot HD that I prefer not to edit in HD, so downconvert in camera. Or when my output is to DVD I would downconvert in post.
How to maintain the 1080p quality to be displayed in any TV?
You don't. The "normal" TV you're talking about probably only have composite input which by nature limits the resolution you're streaming through. Only HDTV have analog component input that allows you to display full HD resolution.

The type of input is a secondary factor. Main reason is that a "normal" TV only supports SD resolution. My old SD plasma has component inputs but it will always be SD resolution. If you think about it it makes sense, because if you could have the HD picture quality on an SD screen there would be no reason to move to HD.

Right, that's the other thing I forgot to mention.

Nasser, all you can do is maintain the quality as best as you can. Usually, that would mean capturing and editing in HD resolution and doing the downconvert right at the end. Other people will say that they have a different workflow that gives the best results for them, so it's difficult for someone new to this to know what to believe.
Best thing to do is try out for yourself different ways of shooting (e.g. HD/SD), editing (e.g. HD/SD timeline, HD timeline with intermediary codec) and downconverting (in camera/post edit), and seeing what gives you the best results. Of course, try to use a short project so you can do this quickly and without spending a lot of effort on it.

Highly appreciated :love4:, any recommendation for basic post gears:happy:

Hi Nasser. I'm using Vegas and Edius. They are quite different, and both have their strong and not so strong points. A lot depends on personal preference as well.
What do you have at the moment? Sometimes an upgrade would make sense, but not always.

Vegas doesn't need hardware, in fact there's not many hardware solutions that are even useful with Vegas.
So assuming you shoot as HDV (highly recommended) you can choose to capture as SD (in-camera downconvert) or HDV.
For HDV you have 2 options as well. Stay in native m2t format, which is what you get from the camera, or convert to Cineform intermediary codec which stands up better to processing because it has higher colourspace and less compression.
I suggest you try out these options for yourself and see what works best for you.
