[SOLVED, sortof] Video not working correctly, Audio is fine

[johncroc]

I have a movie that I watched without incident a few months ago. It is stored on my hard drive as a .mkv

I tried to watch it again today and it is unviewable. If I can figure out how to do it I will attach a screenshot that is representative of the problem. In case attaching doesn't work, I would describe the video as having the top 1/6th of the screen perfect, but below that it's as if the bottom line of pixels in the good part of the picture is just repeated all the way down to the bottom. You can see the tops of people's heads just perfectly, but the rest of the screen is just a bunch of vertical "stripes" down to the bottom.

The audio is fine, as are the subtitles etc. The video is not "frozen". I can tell the movie is playing and every once in a while I have a perfectly clear view of the action for a few frames.

I tried getting a fresh copy of this file, but the new copy plays exactly te same way.

the video codec info is: Codec: H264 - MPEG-4 AVC (part 10) (avc1)

I am playing this using: VLC media player 2.0.8 Twoflower

Any ideas? Your help is MUCH appreciated.

Thank you.

The video is too high of quality for your computer/video card?

For example: if I play a 1080p video, I have problems (sometimes it works tho), if I play a 720p version of the same video, it plays fine. My computer can keep up with a 720p stream, but only barely or not-at-all with a 1080p stream. I recently tried a 4K video (higher quality than 1080p HD): fun was had (no my computer couldn't do it!).

Since you WERE able to play that video months ago, perhaps a video card or video card driver or VLC version changed? Try playing the video in an older VLC (the one you had months ago), to re-create the past & see if it works.

Try changing settings in the new/current VLC to see if anything works better. Specifically, change the video output option...

• Tools ► Preferences ► Simple ► Video ► Display (groupbox) ► Output (dropdown)

...I recommend "DirectX (DirectDraw) video output" or "OpenGL video output"...in my case, my video card sucks, so I have to use DirectX to get hardware-assisted video. My video card can't do OpenGL, with hardware acceleration.

Note: after changing the video output, you might need to completely close VLC, re-open it & THEN play the video. Simply Stopping & Restarting the video may be enough. Also, clicking Video ► Video Track ► Disable, followed by Video ► Video Track ► Enable, may be enough to get the new selection in place, but restarting VLC is the sure-fire way.

Thank you for you thoughts and taking time to respond to my my post. My thoughts are below:

The video is too high of quality for your computer/video card?

I don't think this can be the problem. This is the only video I can find that doesn't play properly. I have many 1080p videos that play just fine (and to be clear, not 1.2G files that claim to be 1080p...12.0G files that are certainly 1080p), this file is a 4.0G 720p file.

I am running an I7-3770K with 16GB RAM, and an EVGA GeForce GTX 650 Ti 2GB video card. I built this machine specifically to be a medium/high-end video playback machine (it's connected to my TV).

perhaps a video card or video card driver or VLC version changed

I have specifically resisted the urge to update the video drivers, because everything was working so well and I did not want to upset the apple cart. It is possible that VLC changed, though. I keep my software up-to-date using software updater in Ubuntu 12.04.

I recommend "DirectX (DirectDraw) video output" or "OpenGL video output"..

DirectX isn't one of the choices in my "Output" dropdown. Output was set to "Default" when I looked (after reading your post), and I tried OpenGL with no success (video looked the same).

Can you (or anyone else) think of anything else I could check or try?

P.S. I am updating the video drivers (from 3.04 to 3.19), to see if that helps.

[johncroc]

I updated the drivers. Still, the video is messed up. Oh, well. Got a new copy (different rip) of the movie and it works fine, all my others work fine.

I'm just going to chalk it up to, "I don't care any more" and leave it at that. Was kind of hoping to learn something about codec compaitbility or something that might be useful to me in the future, but it's not worth spending tons of time on.

Thanks to everyone who read my post and especially to JSLover for trying to provide me some guidance and some things to check.

Greetings, new to this forum .

I have the problem that from all VLC versions twoflower not be played properly and smooth the image ( Linear deinterlacing mode ) . This means that when playing interlaced images there is no slowdown or jumps in the image ( or any audio works OK if very serious jump ) with all recent versions .

This my system:

IOS : Win 7 64bit
Motherboard: ASUS P5Q Deluxe
CPU : Intel Core 2 Extreme QX6800@2.93GHz
RAM: 4GB DDR2 667MHz x
HDD (main): Seagate ST3250318AS
Power Supply: " Enough " dual from total of 940W




All drivers updated .
All this in a properly ventilated tower .
Do not use overclocking.

I uninstalled the EPU Six Engine ( ASUS ) because it appeared that gave problems .

My solution is not so, now .
While my system fails to correctly reproduce the intertaced images with the current versions of VLC only 'll keep using vlc- 1.1.11 -win32 .

If You have a possible solution to get intall the VLC twoflower ...
