Here is a sample I've captured from a S-VHS tape.
I think the overall quality is pretty good (as a layman and starting videocapturer)
But, you guys are the experts, what would you do with this sample to make it better or improve?
I would love to hear your opinion
Here are my tools used
JVC HR-S9600 (Digital TBC on)
Pinnacle Studio Deluxe Capture Card
Captured in Studio7

Your aspect ratio is off causing the people to look wider.I think,therefore i am a hamster.
Good news, bad news.
The capture looks quite good. It is a very stable picture; the left and right edges so no signs of time base errors; you have lots of detail; and you have very little noise.
You do, however, have some pretty nasty dropped frames starting around frame 116. You should never have ANY dropped frames; even one is too many.
No need to capture to lossless because that needlessly creates huge files and will very likely increase your dropped frame problem. If you want to get a little better quality, use an intermediate codec, like Cineform. It is visually lossless and is a joy to use for editing (which is what it was designed for). It used to cost $1,000, but you can get it for free now if you download the GoPro Studio software. However, I don't know if you'll be able to tell much difference from your DV codec: PAL DV can actually be pretty good. If it were me, I wouldn't bother to change codecs and instead would concentrate on your dropped frame problem. That is a BIG deal.
I am not quite sure what is going on with the aspect ratio and also the field order. PAL SD should be TFF, but in my software, it only played correctly if I changed that flag to BFF (bottom field first).
VLC insisted on playing the video widescreen, which is what other people have noted (i.e., it makes everyone look fat), but in my NLE (Vegas) is sensed the aspect ratio correctly. Something does not appear to be set correctly in your capture software. Go back and look carefully at ALL the Studio capture settings and make sure you have them set for PAL; 25 fps; interlaced; top field first; 4:3 aspect ratio.
The aspect ratio flag of that file is 16:9, which is obviously wrong, but the actual video itself is fine.
The dropped frames are the only real issue I see.
Next thing I'd do is find out if the dropped frames are caused by the capture card struggling with the video signal (HR-S9600 has a line-TBC that straightens vertical lines but it does not guarantee a stable output signal!), or if the dropped frames are caused by some problem on the PC side of things. To do that I'd connect something that is sure to output a 100% stable signal at all times, such as a DVD-player or TV set top box, capture some random footage off it and see if I still get dropped frames or if they suddenly stopped. In case this fixes it, it means you need some device inbetween the VCR and your capture card such as the often recommended Panasonic DVD-Recorders DMR-ES 10 or 15 and some others.

The reason that TFF is in my head is that years ago I developed software that let Vegas users automatically stabilize footage using Deshaker by simply pressing one button. It involved writing a script for Vegas, and also one for VirtualDub. The two scripts interacted to get the job done. My scripts had to keep track of the type of video being sent, and if the user decided to send the video from Vegas to VD via an uncompressed PAL file, I had to switch the calls in the script in order to avoid field reversal.
So, for normal DV PAL 720x576 25 fps interlaced, the field order is BFF.
Thanks for the replies!
I know the pinnacle capturecard captures footage in a strange aspectratio (something with sar/dar?) but I can't for the life of me figure out how to change that in the Pinnacle studio settings!
If you look at the screenshots (eventhough text is in Dutch) you can see its 720x576 25 frames a second in full DV quality. I just can't change it,
Does anyone know if I can change this somewere in the install files? Or re-installing the software wil help?
The Pinnacle card doesn't show up in virtualdub
The framedrops was probably my fault, i was messing around with the computer whilst capturing, which i've learned is a big no-no.
I've added a framedropless sample and will re-capture the tape without touching anything
1. You require a frame TBC (at worst, ES10/15 as TBCish), otherwise dropped frames cannot be resolved.
2. Stop using Studio, that is buggy crapware. Use VirtualDub (original, not 2 fork).
Not with Pinnacle open, closed or whatever I do, it's not in the list. When I open pinnacle studio it works fine...
Is there something I need to change in settings or files to let it show up in virtualdub? or is a pinnacle capturecard bound to pinnacle studio?

If yes, I had the Pinnacle 500 USB many years ago and it worked fine in VirtualDub. I just installed the drivers (NOT the software) and it was available as a capture device in VD to choose from.

On another machine I have the pinnacle analog usb pro which works fine in virtualdub. But i want this card to work right.
As far as the 'stretched images' goes. Can i use Avisynth to de-interlace and force it into the right aspect-ratio?
vdub) you can deinterlace and then resize to the aspect ratio you prefer. I would bob-deinterlace ("double rate") in order to keep the motion fluidity.
In Avisynth something like
DirectShowSource("VHSample2.avi") #or a source filter of your choice AssumeBFF() QTGMC() #or a simpler bobber of your choice spline36resize(768,576) #resizing as 4:3 crop(12,4,-12,-10) #cut the crud off #addborders(12,6,12,8) #puts it back into a 4:3 overall frame, if needed

I've put a sample trough AviSynth using this tutorial https://youtu.be/C4PyyQoz6eo
Did a bit of cropping in Virtualdub and rescaling it back to 720x576 (good? Not good? how othewise?)
and exported as mp4 using settings from tutoria.l
And came up with the result in the attachment.
Finished? Or can I improve something?
End goal is to produce a 'best as possible' endresult what we can watch with the family
It's anamorphic encoded now as 720x576. The player must force the playback as 4:3, otherwise you will see it as 5:4 i.e. slightly squeezed.
When you encode it with x264 you should set the SAR 16:15 so players which read the flag will play it undistorted.
What are your intended playback devices? You encoded with subsampling format 4:2:2. While this is fine for playback via PC/SW players, this format may be rejected by your TV for example. So I would consider encoding as 4:2:0 in order to support very most playback scenarios. It's a setting of the x264 encoder (Pixel format YUV420), or add converttoYV12() to your script.

No, if the white are too hot, that MUST be fixed by adjusting the capture settings. You cannot fix blown out whites by using a script.
And the black level may be a little high too. ColorYUV(off_y=-5) or Tweak(bright=-5, coring=false) gets both blacks and whites close to right. Check to make sure that works for the rest of the video.
