digitalFAQ.com Forum - Large flash and red lines problems?

Hello,

After reading this forum and it's numerous "How To", I gave it a try using my far from good workflow :

Daewoo VQ431S (SECAM-L, PAL-B/G; NTSC) -> Magix Video Converter 3 -> VirutalDub 2 (I have just seen that 1.9 is better apparently...)

I have followed the tutorial on how to setup VirtualDub (YUV2 encoding, etc).

Apart from the few dropped frames (2 to 3) I have a lot of inserted frames (1000+ sometimes. I guess it's not as bad as having a lot of dropped one), 2/3 of my S-VHS (21 out of 34) appears to have a lot of artifact.

I know I should buy a correct setup, but I was wondering if this kind of artifact will disappear with the appropriate hardware.

You can find attached what I call a "good" video versus the ones of bad quality. These video are x264 encoding from Huffuyuv RAW (no filter added). You can find the encoding settings at the end.

The two major problems (for me at least) is that if the "flash" artifact is present, it is on the whole video.
As for the "red lines" that you can clearly see on sample n°4, if I adjust something called "PR" on my Daewoo, I can make the lines go lower and practicaly hide them, but then the top start jiggling a lot.

Here are the images when the "flash" and "red lines" artifact appears. There are two version as I found out that they are not the same picture when I capture them using the built-in tool of Sony Vegas Pro, compared to the preview that it displays.

Well I though hotlink would not break on edit and that I could not attach more than 5 files :smack:

Here we go again.
