Greetings everyone! :)
This is my first post on this great board, and since I'm also a newbie I'm not sure if this is the correct forum to post in. So my apologies in advance if it's not! :) Now to my problem which I think is AVIsynth related.
Like many others I enjoy watching movies in high definition, and I recently started using WM9 to backup transport streams. It's been working rather well for me, but every now and then I encounter transport streams that give me a weird problem. Although most of the reencoded movie runs fine, certain segments are extremely jerky (feels like watching a 12fps source). The original transport stream does not have this problem. The jerky segments vary from <1 min to 15 min. I have tried to locate what causes the problem but can't seem manage this myself and now need some serious help. First of all this is the route I go when encoding:
HDTV2MPEG -> DGIndex -> VirtualDubMod
The script I use for 29fps film material is rather simple:
LoadPlugin("D:\DS\dgdecode.dll")
LoadPlugin("D:\DS\decomb521.dll")
LoadPlugin("D:\DS\undot.dll")
MPEG2Source("1.d2v")
crop(0,0,0,-8)
Telecide(order=0,guide=1)
Decimate(cycle=5)
undot()
LanczosResize(1280,720)
I have found out the following using the trial/error method:
It's not a plug-in problem
I have removed all the plugins and tried the following script just to make sure:
LoadPlugin("D:\DS\dgdecode.dll")
MPEG2Source("1.d2v")
This gives the exact same jerky results in the exact same places, although it obviously results in 29fps instead of 24fps.
It's not WM9 related
I have tried different compression methods in V.DubMod, same results.
Well, that's about it. I really don't know what to try next and this is driving me crazy, so any help is very much appreciated! :)
Regards,
Patrick
