MP4 video distortion: green flickering

[cilcards]

I was delighted to find the Prism software, which appeared to be straightforward and easy to use. However, when I tried to convert a short video in m2ts format to MP4, the result was a screen with green flickering all over it. I tried a couple of files, but always with the same result. I downloaded the free software from the NCH Software website, and I'm using Windows 10. The first video I tried was 131MB in its original, but I've also tried with another which was only 29.2MB - which converted into 17.3MB, I notice. Please could anyone tell me where I'm going wrong? Or could there have been a problem with the download? Thanks in advance.

Hello, please try this: 

Try adjusting your settings to the following and converting the file again.

1. Click the Options button on the toolbar
2. Go to the Conversions tab
3. Under Decoder Options at the bottom of the window, select the checkbox for Use FFMPEG decoder
4. Click OK to save the settings

If the issue persist, please open a support ticket here: https://www.nch.com.au/support/supportcontact.html?software=Prism&support

Thanks for replying, but I checked the settings, and they were already set as shown above. However, I now find that just re-naming it .mov or .mp4 seems to work! I'll keep the link though, just in case. Still a shame that I had a shimmery green video after using the software.

I'm having the same problem with Prism for Mac. Latest version. Converting AVCHD files which Prism imports at .MTS files. Get green flashing and big green pixels all over the screen.

I have no green spots appearing but i have a few dvd's in a set that refuse to rip with other software, when in normal playback it works flawlessly, However when playing back using Prism or any other software i get error boxes like files corrupted somehow, I think its got some sort of code that stops programs from ripping.

I have found Prism to actually convert the files which is a massive plus but the error blocks also more than an 30 mins though i get this high pitched wine noise in the audio which i know is not meant to be there.

With those options enabled playback before ripping still has the video blocking at top and bottom sections of video.

Is there a way i can tell the ripping program to slow down when ripping a video that might have errors on it, or even a correction error point please ?

Thanks.

Hi,don't see your update. If the issue still remains, check out the subsequent guide :Compress & Convert M2TS to MP4 . Hope it helps.

There was never an update because i have been waiting for feedback on this issue.

 

I have a DVD that i would like to rip, but when i do get it to rip i have to use the load files feature instead of the quick load dvd from the program.

 

ONCE  i have loaded the files it detects the VOB's which are on ALL DVD's But once i rip them i get Green screen Blips though the dvd, The DVD comes up with a Secruity warning saying this DVD may not be ripped. 

 

I want a copy for my self, But a few select DVD's a blocking my access to progress. What can i do ?

Hello

It looks like the DVD you're trying to rip is DRM-protected. There is no way to rip this DVD without breaking the DRM protection. Prism doesn't allow to do this.

[Andrey Sverdlov]

As for the green flickering/squares or any corruption of the output video. Could you share the input video(upload to Google Drive or any other cloud) and encoding settings you're trying to use ?

[lemonrev]

Andrey, It looks like your first guess was correct, The DVD is DRM protected with a new protection.

However I thought your program had to BREAK some DRM in order to RIP / Convert / Add to other devices in order for that progression to happen ?

If your Package doesn't Do DRM then can you send me to a place that does That doesn't cost the earth ?

The settings im using is a standerd DVD look up / Rip to MP4 or another format it doesnt matter what, Then rip, However most of the time it tells me that it cant rip the dvd, EVEN though it ripped the first season just fine.

Thanks.
