720p vs 1080p to fit on a dvd9.

[wallace4793]

Hi

Im currently backing up my bluray collection ;-) and was wondering if there is much difference in quality to a 720p and 1080p rip used at a bitrate to fill a dvd9. My tv can only support 1080i so i know i will not get full 1080p anyway, Anyone any thoughts?

Well if you're only playing it on a TV, and the TV doesn't support 1080p, there's no point in doing 1080p.

On the other hand, 1080p looks pretty damn good on a DVD9 if you're using H.264. Heck, you can get a good rip on a regular DVD depending on the length of the film and the level of motion.

How are you going to view your backups? PC connected to TV? Or maybe PS3,XBOX360?

What is the native resolution of your TV? A lot that advertise 1080i actually have 720p panels (not exactly, but close enough for government work ;)).

It's likely IMO that resizing to 720p will probably get you better results. It's more vertical resolution in motion scenes than 1080i anyway.

My screens native resoloution can go up to 1080i. Im using an xbox360 to stream my samples at the moment, checking quality etc. I can stream 8mbit files but it jutters at anything over 10, im not sure if its the xbox360 or the stream that isnt being streamed fast enough. ANyone any experience with this? Im using devolo av adaptors that plug in to the wall.

What is your real resolution 1920x1080 or 1360x768?

[wallace4793]

The real resolution of the screen? It is a hitachi pd7200. It states in the spec as 1024x1024 but i assumed this was for the vga and dvi connection, I assumed that the screen can handle full 720p and 1080i as per spec

Sounds like a plasma ? The reason why we are asking for the native resolution is that your display will look best when the content fits the native resolution.

[Atak_Snajpera]

for 100 percent you've got plasma. I've got sad news for you:( It's not even standard HD resolution (1280x720). Your display can accept 720p and 1080i signal but it will be converted to 1024x576 (16:9) resolution. It means that you loose many details. If I were you I would buy something more common like 1360x768 LCD instead of plasma. Good advice for buyers is always look at the REAL resolution not at 720p or 1080i values!

I think the TV has non-square pixels, so all contents would be scaled to 1024x1024

Thanks for the help guys so basically 720p resolution will be as good as 1080i for me? With regards to the tv i bought it 18months ago and it was rated as one of the best hd models at the time trouncing the sony bravia in all the tests and reviews i could find and xbmc looks amazing in 1080i so im happy with in for the moment. Again thanx for the help :-)

[woah!]

actually the 1024x1024 res plasma tv's is better than the 1280x720 ones. more vertical lines of resolution will give it a more crisp picture.

i would go with 1080 backups if you can get a good encode result. if its a long movie, then 720p would help the lower bitrate.

i do all mine at 1080 even tho i have a 1366x768 50" plasma, as i never know what i might get in the future.

I am curious to know what program/utility you are using to rip at 720p? The few blu-ray to mp4’s I have made @ 720p look great on my 46” 1080p. Probably would be hard to tell it from the 1080p source.
