Running Length On Disc

[ADNL]

When looking over the 'Features' of this product I came across this point:

 

"New! Burn up to 60 minutes1 of high-def video on standard DVDs using your existing DVD burner - watch it on your HDTV using a Playstation® 3 or other Blu-ray Disc player"

 

So if I burn HD it'll only be 60 minutes I can record onto the DVD. However, if I author the disc not in HD but in an 'ordinary' format for an 'ordinary' DVD, how much running time will I have approximately? 2 hours? More? Less?

 

Need to know if I can burn long-enough discs...

 

Thanks in advance!

Basically, for any single layer DVD, you can burn one hour in high quality (about 1 hour 50 on dual layer)

 

This is down to the discs themselves really.

 

You can squash more on, but the more you put on, the more the quality will drop (up to a maximum of about 3 hours)

 

However, for HD movies - you would need to consider Blu-Ray really (HD is not the same thing as 'high quality)

 

The suite will burn AVCHD on a DVD - but the encoding takes a VERY long time

.... and, as you can probably guess, having higher quality (higher bit rate AVCHD) on a standard disc may give you less than 60 minutes on the disc. I have seen differing guesses on how much actual time.

HD on Standard DVD uses the AVC codec which compresses the video much higher than MPEG 2 on standard video DVDs. When I create a AVCHD on standard DVD project with menu, here are the estimated times given by MyDVD:

 

HQ 1920x1080p 40m24s

SP 1920X1080i 50m16s

LP 1440x1080i 1 hr

EP 1280X720p 1h24m31s

 

Thanks for that information.

 

So, if I'm reding that correctly, at best quality (HQ) I can get about 40 minutes on a DVD (1080p).

 

Do you have any comments about the apparent quality of the files (ISO file, DVD) with the different settings?

Unfortunately, the bitrate is not given and I don't know of a way to test a file to find out. Is there anything out there like GSpot that reads AVCHD files?

 

I've only done a short 5min test AVCHD to DVD. Quality is very good played back on Cineplayer 5. I don't have Bluray player and don't know anyone that does.

So you can go more quality the less length your project is... unless you're Blu-ray when it gets way better anyway. So something like a 70 minute DVD would be pretty decent quality then... cool.

 

Thanks for the feedback guys!
