Hvx and rendering 1080i footage then....

[Steve McClean]

I have some quick questions that somebody on here can easily answer. Say I film this movie in 1080i 24/pa and the movie is about 1 hour 25 mins. I have all the footage edited together on my computer and render it as a avi file. Wouldn't it end up being about a 1tb file?

Which brings me to my next question how would you begin to put that movie onto a dvd? you would have to have a blue ray disc and burner right?

But doesn't the blue ray only hold around 80gbs? So would you have to take 1tb file and compress it to something else? what would that format be?

I'm just lost on the whole HD rendering process. Would this have to be professional done on a some kind of deck.

thanks

AVI is just a container format. What's inside (audio, video or both) can be encoded using your choice of formats and bitrates.

If you encode using DV or DVCProHD then parameters such as the dimensions and bitrate are fixed. If you encode using DivX/XviD, then you get a boatload of options you can tweak. You'd only wind up with a huge file if you don't compress, or compress very little.

Blu-Ray disks hold 25GB per layer. There are three supported codecs: MPEG2, VC1, and H.264. Encoding and authoring a DVD or Blu-Ray disk is well within the reach of most people with a little bit of tech savvy.

I just thought that compressing something wouldn't make it HD anymore. So compressing has nothing to do with the resolution. I mean you have all these clips in your timeline and you want to render them out but your saying it is useless to render it to a avi file because that is just another container format. So straight from the timeline you would want to compress to what type of file? Would it still be the same resolution or HD.?

I just seem a little bit lost on file types and rendering to make it a legit File for a DvD.

An AVI file is never DVD-legal -- DVDs always use MPEG2 for Full D1 resolution, so if you create an AVI file, it must still be converted.

The only reason for outputting an AVI file would be to do further processing in another application, or if the MPEG2 encoder of your editor produces poor quality MPEG2 files.

Thanks for the info THoff!

So I will just convert from the timeline to a mpeg2 file. Anymore tips or things you think I should know for making a legal file type for a DVD.
