Videosource Problems with VPT 7 on Win 7

[Vici Hanckius]

I like to use VPT 7, its an nice tool, but i have the following problems with the Videosources:

-When I load a Video in to a Slot it has only 50% Intensity

-When I load a seconde Video in to the same Slot both are mixed together, but not synchronously
-the FPS of VPT 7 is only round 4 Frames

I found the similar Problems in this forum, but no satisfying anwser.

-I use VPT 7 on Win 7 64 bit
-1 AMD Radeon R9 270X
-(no second GraphicCard)
-QT installed
-Video driver checked and reinstalled

Hi,
thanks for the detailed report. I wish I had an answer for you, but since there are no obvious errors in the log I am not sure what´s going on. Hopefully some windows 7 users can chip in on this?

Hello Vici,

This is a "guess" as I have never had this problem in VPT7 under win7.

I see in your screenshot that the video (1) is not triggered (the T button 2 to the left of the preview window), and you have a half second X-fade.

It is likely that the videos are just not running.  They need to be triggered when selected so as to run.  So you probably have both videos frozen in the X-fade between the two, and as they have not "run" you have an incorrect frame-rate.

Please let me know if I am wrong, and then I will look at your problem again.

Good luck,

David.

[Vici Hanckius]

Thanks for your help,
i tried the same project without problems with another old win 7 notebook, but its to old and bad for big video files.
I also activated the trigger button and set the x-fade to "0","1","2"and"3", then i reloaded the video files, but it doesn't solved the problem.

I can see nothing wrong immediately, and I cannot reproduce the error. At the moment I have few ideas.

Do you still have the VPT7 folders and all of their contents exactly as they were downloaded, or has something been moved?

What is the content of the prefs.txt file, and especially what is the frame rate?

If you click the "current" box above the sources, is there anything wrong in the table?

If you save one video (shift-click a source button 1) to source 1 and do the same for the second (saving to source 2) does that then allow you to switch between them correctly (by clicking the source buttons).?  Or do you still have 2 videos loaded into the same slot?

David.

I have the feeling this is another graphics card issue since it shows the same symptoms as the ones with dual output. I guess the only way to find out is if there are other VPT users with the same graphics card.

[David]

Yes, you are probably correct.

I just googled "your card" opengl problems and there are a few gamers complaining of low frame rates/ bad drivers etc.

But are you certain that you have only one card?

Has your machine an intel cpu with an on-core HD3000/4000/? gpu?

David.

[Vici Hanckius]

I also tried it with the original folder from the website.
Saving in to the source presets still have the same effect.
:(

Extraxt from the "current table":

The fps problem is solved, but i don't know why?
Now the fps is about 30.
The Video-source-overlay-problem is still there.

I don't have an integrated GPU on mainboard or cpu and i only using one R9 270X

I googled too for problems...
Could this be a framebuffer problem?

Vici

[David]

Hello again...

The only difference in my prefs.txt file is that fsaa is on (1 instead of 0)... but I think that has to do with anti-aliasing so I do not think it would change anything.

In my "current" table the path to my videos (videopath) is default, unlike yours which has the whole path.

I think that is because I changed my projectpath.txt contents to........ project "defaultproject" 0 

Otherwise I see no differences,

I don't know much about video cards, but there are a lot of "gamers" that do, and you might find help on their forums.

Good luck,

David.

[Colin Bryson]

Do you have any further insight to your FPS problems?  I also have an R9 270X, running Windows 10, and I have the same framerate issues.  A single 720p video runs at 3-5 FPS, while the exact same setup runs on my Surface Pro 3 at 30+.  I have the latest drivers, QT 7.7.6, and have had no luck.

[David]

I do not know the absolute truth, but a few gamers have had problems with this gpu.  Some have reported that a firmware update fixes the framerate problem and I have attached a screenshot of a post that gives a little more info (especially win8).

However, win10 is far from a "finished" product, and you could have driver issues affecting the gpu, or even affecting fan control (heat issues), motherboard comms etc.

So I have sacrificed (temporarily) my MacBook Pro (Bootcamp win7).

I had cloned a working win 7 with VPT7_01 to a new 3rd generation HD4000 and updated all of the drivers before running VPT.

The max window declared a fatal error for ad_mme.mxe and for sure.....no sound...........and the horrific double half brightness video syndrome!!

I had recently noticed a similar (but midi) error on my working version of VPT, so with great confidence I removed ad_mme.mxe from the "ad" folder of my mac and ran VPT........

Exactly the same symptoms.

No problem.  With great confidence I put the file back and started VPT again...........AAARGH.

Ok, no problem, I reinstalled VPT7_01...... AAARGH

Ok, try VPT_02 again with a reboot.......AAARGH

Remove and reinstall quicktime...........AAARGH

So Vpt7 (max 32 that is) writes to the registry, or replaces some dll's or does some other thing to windows when it is run.

And when (if) there is an error it cannot afterwards recover...... no matter how you try.

The system, the drivers, everything is identical but it fails to run as before.

When I get time I will (maybe) clone a working system prior to this experiment and then bit by bit compare with the broken system...

Unless one of the cyclists can tell me what is going on?

To follow.

David.

thanks for taking the time to explore this David!

SOLVED>>>>>>>>>>>>>>>>>>............!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

It's an audio problem (the half brightness double video) or just simply VPT not running properly.

I had noticed (often) similar problems in Pure Data.

I was about to write suggesting that you include "Dsp status" in the next standalone release, but it is already included in SoundTrigger_VPT7_win.

I opened that from VPT7 and went to audio settings.  Audio was off.  Once I had set audio to the correct output (mme for my system without an external card) I was able to get the sound working again for my videos AND THE VIDEOS ARE BACK TO NORMAL!!!

Please excuse the capitals, but I am rather excited.

I might try to write a tutorial.

Maybe DSP status should be a part of the VPT7 standalone?

David.

[hc]

Sounds weird that the audio driver affects the the blend level of the video, but if that solves the problem that´s great!
Here is a small patch (unzip first) that you can open in VPT that lets you access the audio status window.
Let me know if this works.

[David]

Hello hc.....

Thank you for that.  As I was looking for where to put the file I found that the audiostatus patch was already in your release, along with an audio channel patch and a Gl graphics status patch as well !! Brilliant! I had not fished around in those folders until now.

I am not surprised that an audio error could cause this video problem (as it has for me on two windows systems, only one of which has 2 graphics cards).  Max is a close cousin to Pure Data, and in Pure Data an audio error will wreak havoc... to the point where the program will just bounce in the dock on OSX or hang at startup in windows.  A slight mismatch with the sound card could also cause the occasional frame-rate problem, as audio is normally given priority and if the audio is held up then the video will be as well.

David.

[Vici Hanckius]

Hey HC,
Thanks for the audiopatch.
Now, it's working, without phantomvideoproblem.

VH

[David]

If you have come to this thread because you have a problem with.......

Phantom video

Video at 50% (50 per cent, percent) overlaid on another (even within the source monitor)

Overlay of two videos in the source

Double video in source

Dim video

and you try to solve the problem by resetting the audio settings for VPT7.......

Please post here again to let us know....... whether you managed to solve the problem or not.

Then HC will know whether the problem is solved and whether the solution should be added to the FAQ.

David.

I was having the issue awhile ago and gave up..started using an older single card laptop. I fired up this again with the audio patch and it seemed to have solved the issue....at least for the first test. Difference tho is now I am using win10 and not win7/plus new updated Radeon drivers..so it's not the same setup as the initial issue. (i think?). I have Radeon HD 7976m +an onboard intel 4000.
