I have a big problem here that I hope someone can help me with. It's a bit complicated so will try and keep as simple as possible.
In 2008 I copied some family video tapes (PAL VHS) to DVD. I used a Sony DVD recorder (HXD770). This has a hard drive so I recorded them to the hard drive and then burned them to DVD. At the time I had a CRT TV and I remember watching them back and they looked pretty good and was happy with them. It's now 2015 and the CRT is long gone and we got the DVD's out the other week to watch on our 1080p HDTV. I still have the Sony HXD770 and a PS4 for gaming and BluRay watching. I decided to watch the DVD's on the Sony DVD recorder. It is connected via HDMI and the output is set to 576p.
I turned on the first DVD and within a few seconds I noticed that on any movement I was getting pretty bad interlacing lines! I tried other output settings (720p, 1080i and 1080p) and they were just as bad. I was getting thick black interlacing lines on the edges of things and finer lines on other things. In desperation as to what was going on I tried to output using 576i which was greyed out on the menu. I had to change the output colour settings to allow this to be selected and then played the DVD using this output. The quality of the picture wasn't as good overall but the interlacing lines for the most part were solved.
I then decided to put the DVD in my PS4 in case the Sony DVD recorder was just doing a really rubbish job of de-interlacing anything above 576i. The PS4 only allows me to output in 480p (I am in PAL land so that's a shame) 720p, 1080i and 1080p. I selected 480p and the playback seemed to be 95% okay with only minimal interlacing lines on fast moving scenes. However (and this is what is annoying) I noticed that on many brighter parts of the picture it has fairly thick grey lines. These are hard to describe but are like thicker interlacing lines. If I select 720p, 1080i and 1080p these lines are not so thick but the interlacing problems are back with loads of fine lines appearing on scenes with movement to the camera.
So, my question is what is going on? When I recorded these DVD's to the Sony DVD recorder I used default settings (PAL 720x576) and the bitrate was set to HQ (maximum). This gives an average bitrate of around 9.3mbps. I know from reading around on the net that this is considered high but they seem to play fine without stuttering. I have checked the video settings and TMPGENC and Restream both tell me that the DVD's are upper field dominance which I believe is correct for PAL SD video.
I have tried playing these DVD's back in VLC media player and if i de-interlace using blend then I get the normal ghosting on fast moving scenes but I also get these jagged interlacing lines. The DVD's seem to look okay using the discard method of de-interlacing though. They aren't perfect but they are okay.
The tapes unfortunately got badly damaged when moving house a few years back so I can't re-capture these and need to try to get these DVD's to play on an HDTV above 576i without looking like an interlacing mess. Can anyone tell me what the problem may be as it's a bit upsetting to know that these DVD's may be screwed up as they have precious footage on them.
