Finally you can achieve better bitrate accuracy and so more accurate file sizes (at the expense of speed) given the appropriate params, but ConvertXtodvd doesn’t do this in favour of speed.SVCD2DVD v2.5, AVI/MPEG/HDTV/AviSynth/h264->DVD, PAL->NTSC conversion.

That is my problem with ConvertXtoDVD....load one 700mm xvid...the "traffic light" shows excellent encoding capabilities....then gives you a 2.2gb DVD.
Load two 700MB xvid files(with movie lengths that should be too much for one DVD)...the traffic lights show yellow....and it still gives you a DVD just above 4gb...nowhere near "full".
It does do great PAL to NTSC conversion though...gotta hand it to it on that one. -

I'm not defending or attacking ConvertX: it does a great job for quick & dirty conversions and I used to use it alot. But unless something has changed dramatically (i.e. they don't use ffmpeg anymore), there is no way anyone is going to get similar quality to CCE or HCenc. And the sizing issues would suggest they are still using ffmpeg -

Agreed! It's gets you a watchable menued DVD very fast & in decent quality
btw..installed v.3.53.139 & can find no reg setting to enable 2 pass. They must have taken it out after it being reported -

very cool, thanks. Will play around with it & a couple of 720P .mkvs I have as testers

eh, set to High Quality settings, with 2-passes, it still spit out a finished VIDEO_TS folder only 2.87GBs.
Don't see much diff, the 2 pass seems to not do anything worth the extra processing time. ah, well... -

This is based on a source that contains a fair amount of action. Although there may be a slight softening of less complex scenes the high action parts should look better, obviously this is where most notice artifacts, blockiness/pixilation/ghosting whatever folks like to call it. The way they have set up their 'Profiles', 'Medium" will allow for more bitrate for the complex scenes.
More confusion. For longer running time sources 'Medium' should be used (again assuming a fair amount of action).
Also note CXD was originally developed/optimised for speedy Divx/Xvid conversions. It's now probably the most consistent converter for those who download off the net. No codec fiddling required.
All this is fully explained at their forums by a member who has done over a hundred different tests, posting many graphs and charts comparing bitrate distribution etc. -

Hi there
I m Fabrice, and co-owner of VSO Software, the company which makes ConvertXtoDVD. I don't know if I should feel good or bad about the fact you have published the hack of the 2 pass. just a quick word.. from our test for now, the 2 pass doesn't change really the quality, but there is a real difference ( maybe not visible ), till you are in the hack, you should better find the one controling the filters used to rescale the image, because in this case there is a BIG and VISIBLE change in the quality of the image. By default we are using for now a fast linear filter, but if you change it to Lanczos, the image will be sharper -
you may understand I don't want to put the information, as it is a feature reserved for upcoming v4, you could have this if you agree to keep it for you only. We don't mind to welcome new beta testers ( the top contributors got the access to very internal reg keys ), if you have a IM account to report and be in touch with technical team, and if possible a valid license for the program
-
also, we are working on multi-core optimisation, it is still under dev, but the gain ( especially with advanced filters ) will be quite nice.

I just recently ran into my first instance of a 2-pass job looking worse than the prior 1-pass for it had. (For lack of better terminology, I would call it a very fine-grain blockiness in the texture, &/or maybe a decrease in sharpness ?) No other settings had been touched. So far, I think I had found the 2-pass to be a wash at worse, and somewhat better in many cases. Not a big enough sample yet to say for sure, though. I'm thinking that your source has to fall within certain quality (and maybe format / codec) parameters to really benefit here, and I'd sure like to learn how to identify just what they are. On a reasonably fast dual-core or better, the 2-pass hit in job time is not too bad . . . but then I'm coming from several years of using a single-core P4.

you might want to gander up a few posts to see lapinou's comments on the 2-pass
-
my only concern is you are testing 2 pass with a set of filter not optimized for quality. so whatever the number of pass, you start with pretty bad condition. My only suggestion is to contact VSO to be enrolled as official beta tester and you will be able to get the best settings to "enjoy" the 2 pass later ( even if the difference isn't big )
-
MysticE: That is quite interesting, and the first I've heard of a reason to choose something other than the Slow | High Quality setting. (But I must confess that I have not read extensively in the VSO forums.) I'm not afraid of a packed or nearly-packed disc . . . and I do wish to maximize the picture quality. So, what if one's sources do not involve a lot of action ?
for lapinou: I'm very interested in that lanczos filter, as an alternative to the 2-pass. After sifting through your registry settings, I'm going to take a wild guess that this is enabled in the key for
resample_method ___________ where it currently says __________ IRM_FAST_BILINEAR
but since I don't know for sure, or exactly what would get plugged in there instead, I wouldn't risk messing with it.
I may take your suggestion and contact VSO privately, but I have some doubts as to my qualifications to be a Beta tester, or whether my limited volume of ConvertX usage would be of much value here.When in Las Vegas, don't miss the Pinball Hall of Fame Museum http://www.pinballmuseum.org/ -- with over 150 tables from 6+ decades of this quintessentially American art form. -

in this part, which can be very important and cpu consuming, we also need to make some color convertion ( RGB to YUV which is the standard for video on tv ), this step and the rescaler has been completely rewritten, and that's why it is a beta version.
speed and color should be better and faster, your comment on this part will be welcome.

Most would likely be due to content, some due to technique, etc. Anyway, I'm not digressing. One of the rather nifty ones I stumbled across recently is here:

It looks pretty good on my computer monitor screen (played normally -- never checked it out fullscreen), but if I run it through ConvertX to make it DVD-friendly and ready to show on a TV screen, it looks pretty bad. Converting the kind of video you find online is one of the main reasons for a program like ConvertX. But, in a nutshell, I think this is the problem: so much of the video you find online is just not good enough in quality. It probably won't make enough of a difference, no matter what settings you change in ConvertX, and probably no other encoder or program out there is going to give you results that would be significantly better.
I've seen plenty of cases where if I just put the .AVI or .MPG file on a thumbdrive and if the Oppo is able to play it, that is probably about as good as it's ever going to look on the larger screen.When in Las Vegas, don't miss the Pinball Hall of Fame Museum http://www.pinballmuseum.org/ -- with over 150 tables from 6+ decades of this quintessentially American art form. -
