jumping video after authoring

[smokiespliff]

Hello!

I think this would be the right place to post this (as opposed to the capturing section).

I've successfully captured video to my hdd using PowerVCRII. It plays fine in media player/PowerDVD from the hdd, but when i author and burn to dvd, the video is ever so slightly (but annoyingly) jumpy in places.

I've run comparison tests and it's definitley not like that in the captured files, but remains the same from the dvd, no matter if its on the standalone or through the dvd-rom.

I've authored first with NeroVision Express 3, and then with WinDVD Creator which returned better results, but was still slightly jumpy.

Then I tried with DVD-Lab Pro, but I've yet to get to grips with that one, and couldn't even get the sound in sync, even though I didn't tamper with it (apart from de-muxing and audio transcode from 41khz-48khz).

Basically I would rather use a simple authoring program like WinDVD Creator or Nero to easily author (I don't really need menus) and burn without much input from me, so would anyone have any suggestions regarding the above programs, or recommend a different one?

Thank you!

You may not be able to get rid of every bit of jumping. This *may* help...

I'd start with capture, making sure you're capturing both fields (interlaced) at the highest quality possible. Playing back a captured file on your PC won't always show a problem with interlacing -- one way would be to go through some of your video in VirtualDub frame by frame to see what's happening. Problems like reversed or broken field order should be apparent as stalled or reversing motion.

IVT might make the picture look better, but will not add to smooth playback -- deinterlace might work either way depending on content and personal tastes, so something you might give a try on a test file.

If the captures are OK, try a separate encoder, though you may have already done this if you used DVDLab. Make sure the encoder knows the correct field order of your captured files. Also try a short length video test so you can encode at max DVD bitrate if your authoring program doesn't give you a lot of control over mpg2 settings. Make sure you're encoding NTSC or PAL interlaced -- not 24p with pulldown.

This sort of thing might help re: smoothness, or give you some clues to get better results -- good luck

cheers, i'll give it a go. i think i'll modify my capturing method and see how that turns out so i'll know if its the capture or the authoring.

cheers

Try burning at the minimal speed of you disks. I use CopytoDvd as my burning driver and I have set the max. writing speed to 1, that way when I burn the driver always requests the lowest possible speed.

Since doing this I have not had to throw away messed up disks.

Hope it helps.

As an alternative (just to see if you obtain better/different results), you might want to try authoring with easy-to-use "TMPGEnc DVD Author". You can obtain a FULLY functional free 30 day trial version of this commercial program at:
