    Graphics Card Problem?

    I believe that I may have a graphics card problem as I am having some display issues. On the timeline, I can put down a video track, add transitions and titles on the track above the video and all will be fine. However, after moving on with the project, I later find that where I have put a title all I get is a black screen ie no video picture. I can remove this by very slightly moving the title but when I do it that it causes a similar problem further along.

    This is not only applicable to timeline footage. If I output a DVD I get the black screen.

    I cannot see what else could cause this other than a graphics card problem. I know that it is not the drivers as it exhibits under different ones.

    What do the experts on here think?

    Bob - does the computer misbehave with other programs? I assume you are thinking this is hardware.

    Have you checked DirectX?

    Hi Jeff

    There has been no problem using other programs. How might I check Direct X please?

    Re: Graphics Card Problem?

    Press the windows key and E, then in the run box type DXDIAG. That will give you basic information about what version you are running and show any issues.

    HI Jeff

    It says no problems found.

    EDIT Just had a further look and sometimes it is only the transition which causes the black screen. It disappears afterwards and then displays the title.

    Re: Graphics Card Problem?

    I am attempting to find some common denominators and have found that my football projects are not affected by this problem. The video format for these is always from my XDCAM camera in an mp4 wrapper. The issues that I am having is with my archive motorcycle race footage in an avi format. Could it be that my graphics card is having a problem in dealing with the avi files and copes with the more modern mp4 ones? There may not be a great deal of logic but having pinpointed this significant difference, I would like to find out the source of the porble. and if necessary, install a new graphics card.

    Re: Graphics Card Problem?

    This doesn't sound like something that will be solved by a newer graphcs card to me.

    Is the AVI footage Interlaced? And if so, do the project settings reflect that? Are these transition being added in the old "Overlap video" style or the new "maintain Sync" mode?

    If you can upload a sample of the footage, or better still an AXX project that shows the issue I can test it on my system, but ISTR you don't have the internet access for that?

    Re: Graphics Card Problem?

    Hi Jeff

    The transitions are simply disolves created by dragging the edge of the titles and as I stated earlier, these titles are situated on a track which is located above the video track. The avi files were originally created by Studio using the importer to save them from tapes to external hard drives and so I suspect that Studio would have no problem in dealing with them. I will check the answer to your question regarding interlacing and project setting once an output to file that I am currently undertaking completes.

    Re: Graphics Card Problem?

    Fingers crossed Jeff, you may have 'hit the nail on the head'. I changed the timeline setting from interlaced to progressive and one title that was not previously displaying suddenly worked again. I am now going to output the entire project to a DVD and then check the result. I will report back later.

    Re: Graphics Card Problem?

    It looks as though that was the answer as it has output successfully. Would I have a problem in attempting to mix progressive and interlaced on the same timeline? I have other items that I think are interlaced and I may need to produce a mix of them when preparing a DVD for a client.

    Re: Graphics Card Problem?

    Yes, it may Bob.

    However, what I think may be happening could be something to do with how you are adding the transitions. You say that the original files were interlaced, but the problem only stopped once you had switched the timeline to progressive, or did i missunderstand?

    Re: Graphics Card Problem?

    Wasn't there an issue with transitions a while back? (can't remember whether it was in PS22 or PS23...)

    • PAL (25fps) project
    • Transition was created in "Maintain Timeline Sync" mode, and was an odd number of frames (e.g. 1 second)

    If Bob's title that blacks out is touching or overlapping such a transition, maybe he's found a new trigger for that old bug?

    FWIW I always use "overlap clips" mode here (I use a lot of manually-created scenes, which don't automatically provide any head or tail meat for a "maintain timeline sync" transition - I'd need to pre-trim nearly every scene to avoid the out-of-meat / freeze-frame during transitions)

    Regards,
    Richard

    Re: Graphics Card Problem?

    Yes Richard, that's the direction in which I'm working. An interlaced PAL clip that has been equally spread by the Maintain Sync mode could result in a transition starting half way through a frame. This resulted in black. I though they had fixed it, but perhaps not in all scenarios.

    Re: Graphics Card Problem?

    Hi Jeff. I am not absolutely certain that the clips are interlaced, I just had it in my mind that they were. It is possible that they are progressive. The files are too large to put them into Mediainfo to check.

    Hi Richard. The transitions concerned here are just dragged dissolves applied to each end of the title to fade it in and out. 

     

  •  03-11-2020, 11:20 796244 in reply to 796243

    Re: Graphics Card Problem?

    Bob - you can use a program called MediaInfo to check the properties of any clip - sometimes Studio's Display Information box can get it wrong.

    Anyway - is it working? :-)

  •  03-11-2020, 12:03 796248 in reply to 796244

    Re: Graphics Card Problem?

    Hi Jeff. These are very large files which I have attempted to put into Mediainfo before and they have not worked. I will try these again.

    Yes, I am able to successfully output a DVD using the progressive option on the timeline.

    Here is the Mediainfo analysis. I cannot see where it says whether or not it is interlaced.

    Re: Graphics Card Problem?

    You'll kick yourself. It's the field that says Scan type: Interlaced.

    Re: Graphics Card Problem?

    I see it now Andy.

    Since this is interlaced then Jeff, can it be that Richard's theory of a bug returning is correct? I can overcome it by changing to progressive as the timeline setting.

  •  03-11-2020, 14:08 796264 in reply to 796262

    Re: Graphics Card Problem?

    Yes, I still think it might have something to do with Richard's suggestion.

    Just check what Studio thinks the files are. In Display Information (right click on the clip on the timeline), check that Interlacing is shown as Bottom Field First.

  •  03-11-2020, 15:06 796267 in reply to 796264

    Re: Graphics Card Problem?

    Yes Jeff, it does say bottom field first. Is there anything detrimental in my cheating by using a progressive timeline setting for these files?
  •  03-11-2020, 15:26 796268 in reply to 796267

    Re: Graphics Card Problem?

    With "progressive" settings Studio will de-interlace the video for export (in my experience seems to do a perfectly adequate job of it); movement might not appear to be quite as smooth as you've gone from updating the picture 50 times per second (albeit half-resolution fields) to only 25 times per second (updating the entire frame).

    But, regarding any possible Studio bug , what transition mode are you using ("maintain timeline sync" or "overlap clips")? And how long are the fades each side of the title overlay? If an odd number of frames, what happens if you change the duratiion of the transition by 1 frame (e.g. from 1 second to 24 frames)?

    Regards,
    Richard

    Re: Graphics Card Problem?

    Hi Richard

    I am having something of a terminological problem here as I do not understand how to differentiate between the two types of transition that you mention. All I do is to place the title on the track above the video track and then simply 'pull' the dissolve from either edge of the title in order to achieve a fade in and out of the title. How can I determine the length of the dissolve as I do not set it precisely?
