Why convert DVD to 720p or 1080p?

Produce macroblocks

Very poor deinterlacing

AC6 and 6 channels forced

disappointing.

Hi,

* "Why convert DVD to 720p or 1080p?"...
Converting DVD format to 720p or 1080p is usefull for users wanting to see DVD Videos with an HD installation (720p/1080p TV screen).
If you try to display a DVD Video on a HD installation (DVD home player plugged on a HD TV), the resize process from 576 to 720p/1080p is done by DVD player (or TV) hardware chip.
After a lot of tests (more than 30 DVD home players tested on HD TV), we realized the final quality was very affected by hardware upscaling.
When you convert a DVD format to 720/1080p with DVD Converter, the resize process is done by our resize filter resulting by a better quality than hardware process. (VSO resize filters are selectable in step 2 with "video quality" setting)
Like HD TV doesn't need to resize the converted video, the video quality will be greater.

Maybe have you an HD TV screen/DVD Video player having a very good upscaling chip, in this case 720p/1080p output profiles are useless for you (but Ultimate version have another usefull output profiles...)

* "Produce macroblocks"...
Like resize process is done before encoding the frames, converting 576 to 720p/1080p will not produce more macroblocks than another input format.
Macroblocks are related to encoder settings or average bitrate requested (too low).

* "Very poor deinterlacing"...
Maybe can you give me more details? If you have a problem with deinterlacing, I'm ready to fix it...

* "AC6 and 6 channels forced"...
Same as previous!

"disappointing"
For sure, if you thought converting DVD to HD format was useless, you could not be happy.
For my case, if I think a program will not be usefull for me, I don't use it

Thanks!

This is just guessing, as I haven't really tried this with DVD Converter or even newer versions of ConvertXtoDVD, but ConvertXtoDVD 3.x always had an issue with interlaced MPG2 streams since it ignored the field order stored in the stream and applied interlacing even if a lossless progressive conversion was possible resulting in pretty terrible artefacts. I don't think this was ever fixed in ConvertXtoDVD, at least the developers where not very enthusiastic about fixing it at the time I reported it: http://forums.vso-software.fr/wrong-han ... t9767.html
So maybe this old issue has sneaked into DVD Converter as well.

Hi,

Deinterlacing support has been added since 1.2.2.6 version.

Thanks.
