Ghost Image when capturing an screenshot

candylovergirl wrote on 1/11/2020, 3:34 PM

Hello,

VMS 16 b175 on a Win10 PC

The video I am working with is an evidence for the police, they asked me for the .mp4 file first and now the Mexican police also wants screenshots of the event printed in full color.

The videos are not recording with a pro video camera, the events are save with a PVR of a Cctv system.(1080p)

  1. I need to insert an USB stick to the PVR to extract the events I want to work with.
  2. I need to convert them using HandBrake in order to work with them in VMS
  3. The video plays nice, but If I want to take a screenshot of an specif frame this is the result:

Is there something I can do to avoid the ghost in each screenshot I am taking?

Thanks

Came

It looks like ghosting caused by blending the fields of interlaced material but you state it's 1080p so it cannot be that.

Could it be resamping if your source framerate doesn't match your project framerate, or you are varying the play rate? Go into the clips Properties or Switches and Disable Resampling.

Thanks, but I can not find where I can Disable Resampling 😳

Go to the (Timeline) Event's Properties, Video Event tab. Or "From the Edit menu, choose Switches (or right-click an event and choose Switches from the shortcut menu)."

Also, make sure your timeline properties match your source properties.

Another possibility is that the ghosting may be in your source file? The PVR may have shot with a slow shutter speed, or your Handbrake settings may have introduced the ghosting. Play the file in VLC one frame at a time (E key) to check.

It's interlaced, which is still common in some HD formats. Source properties, please.

The steps I have taken in the past to enable a screen shot without ghosting are:

On the Vegas timeline, pause at the point you wish to capture.

Switch your Preview setting to Best, Full

Use the arrow keys on your keyboard to move one two or three steps to the right or to the left

Somewhere in there will be one clear ghost-free frame

Use the Save Image button to capture that frame, review it and hopefully it is ghost-free.

Don't forget to change your Preview settings back to Preview Auto, this gives best preview playback without stutters.

I hope this helps

Still waiting for those MediaInfo properties.

That said, it sounds like either a project mismatch, as was mentioned before, or you got a bad second-generation copy, not the original foitage format.

VLC and other players can do frame shot.

Do you still see interlacing when shooting progressive? I recently had a QC come back with ghosting, when the project was shot in 4K at 30P (on a phone, if that matters...) and the project was 1080P the whole time, but there was still ghosting - but not with the lines, like you see freezing a project with field orders.
