352x480 Resolution Compatibility

[nyijedi]

I heard that when using a low bitrate (I am using 3700 to encode tv eps) it is better to use half D1 resolution than Full D1. These play fine on my t.v., DVD-Lab did mention that some t.v.'s have trouble playing half-D1 resolution. Is this true? From people's experience, at what bitrate should I switch from half-D1 to full-D1 resolution?

Also, I have read that if you are using an external capture device (I am using the ADVC-100) there is no noise pickup during captures. Does this mean I should not bother with any filters? Can anyone recommend any good VDub filters to remove noise/blurriness from captures? Thanks for all of your help guys.

I think you have been given some bad info and half truths. TVs have no problems with full, three-fourths, half or one-fourths resolution. This is more dependent on your DVD player's compatibility. Just about all recently released (2-3 years old) DVD players can handle full and half DVD resolution. As for bitrate, it is again dependent on your DVD player. But I would venture to guess that 3700 kbps should work just fine. I would suggest doing a small 5 minute clip and test first. On my DVD player half DVD resolution (aka Chinese Video Disk - CVD) has a max rate of about 4500 kbps. But that resolution is overkill for half-DVD. I would say your average bitrate should be 3000-3500.

Again, the info about the ADVC-100 is not correct. It DOES NO FILTERING. All it does is capture uncompressed video (and VERY WELL I might add). If there are artifacts in the source video the ADVC-100 will grab that too. Filters?......... Dynamic Noise reduction / Smart Smoother / Temporal Smoother / Sharpen or XSharpen. There are so many, it gets confusing after a while

Missed part of your question. What bitrate for full DVD? Well put it this way, Hollywood uses an average of 4500 for the bitrate. There is some give and take here that will depend on what is most important to you. Quality vs Quantity on a disk. I have found that a ripped 2 hour 15 minute DVD can use a bitrate of 3500 average and will look much better than that of say 1 hour 40 minute soccer game captured from TV at the same bitrate. It wil be dependent on your source video and how much you want to fit on a disk. You can max out at about 9000 at full DVD.

I know I just confused even more ..............sorry

Regarding the "problems switching to half D1" issue.

The example, if memory serves, was having full D1 menus and half D1 video content can cause some players to have problems, the TV wasn't really the issue. DVD-Lab won't stop you from mixing menu/movie res, but it gives you a warning.
