BD 15mb/s Vs DVD 9.8mb/s

[VideoChunkster]

Has ayone tried this out as of yet?. With the higher bitrate of blu ray converting vhs, does the extra bitrate make any difference over the dvd specs without any restoration treatment done, just straight transfer? Look any better than the same vidz transferred on basic dvd?

Not I.

It easily could make a difference, a big one. Especially if the source is interlaced, especially if it's very noisy (as 'unrestored' VHS material often is), and especially if the material is complex (doesn't compress well). One of the great complaints against DVD is the low max bitrate allowed. However, if you really care about your videos you'll 'restore' them as best you can because a higher bitrate mitigates only one of the problems with VHS sources.

Thanks for your reply. I wonder how many people have tried this now. How many hours of vhs content would fit on a BD at 15mb/s bitrate?

You can use various BD bitrate calculators. Assuming 15Mb/s, 192kb/s audio, about 206 minutes on a BD25

You can actually use higher than 15Mb/s and h264 for SD blu-ray . But by far the better alternative is to "improve" it first. Cleaning VHS transfers significantly reduces your bitrate requirements . In the end you'll be able to fit more footage on the disc and have better visual quality if you filter it

I don' t know of anyone who has transfering without filtering because it's a pure waste . Even pristine VHS footage benefits from light processing . If you have noisy footage, your extra bitrate is wasted in attempting to preserve the noise

for BD you are not limited to use mpeg2 only:

less and less people actually put their videos on BD, but just on hardisk so videos are ready for streaming, ready to be dealt with in bulk (copy, paste),
but if I had to do it I'd encode H.264 using CRF, not mpeg2 and give it some basic denoise at least

Thanks for the replys guys, good info.

If you denoise and use x264 to get H.264 be generous with bitrate, use CRF15 or 16 to avoid banding. SD resolution is blown up on the screen and those bandings, pixelatizations in dark areas are much more visible on HD screen. But you still should be under 15Mbit you mentioned using CRF 15 or 16.

I know it sounds kind of counterproductive to denoise to supposedly obtain lower bitrate for certain quality and then demanding more bitrate to avoid banding, but overall result is much better. This is SD resolution situation, every noise or banding is much more visible on bigger screen.
