I have Studio 11, latest version on an AMD 64X Dual Core 2.4 system with 2 gig ram. On conversion from m2ts (Sony SR11) to WMV HD sometimes the converted video will have video glitches. In these glitches its like a millisecond scene from the video just flashes during the playback. It does this, again sometimes, regardless of which WMV HD output I select. THe convervsions are straight from the m2ts file with no titles, transistions or cut. I always start a fresh project and delete the aux files. I have done a 1 hour covnersion that was fine throughout and then do another or the same one again and it might glitch 3 or 4 times. I just completed one that glitch approximately every 10 seconds. I did it again and it ran fine the first 3 minutes then the glitch started and continued approximately every 10 seconds for the 2 minutes of remaining video.

This is not a playback issue. It is in the conversion as I have confirmed the glitches on 3 computers. I took not of the time of each glitch during playback and on the other computers, using that same video, the glitch times are the same.

 BTW... I have made sure my drive is degragmented, closed down all unnecessary programs, disconnected from the internet, shut down all protection or any scanning program, screen savers, etc..   After this failed I formatted the system and with the exception of the latest drivers, windows updates and Studio 11 itself, I installed nothing else so this problem happens on a CLEAN system as well. 

This makes Studio 11 completely useless if I cannot make a video without this problem.

I'm sorry I have no solution for you.  However, if it is the same bug, there is more discussion here and here.

Socal,

I have gotten rid of glitches going from AVCHD mts files to standard def by watching an encoded movie, then going back and adding an effect where the glitch was. This forced Studio to re-render the effect. I then promptly delete it and then make a new movie. A slow and painful process. You can try deleting your aux files and then allow Studio to completely rerender the effects in the movie using background rendering.  In this case, I make a point of not to use the computer for anything else during this time. This also seems to mitigate the glitch issue. My glitch symptoms are:

• 1 frame of a previous clip or photo (often zoomed - just a portion is shown)
• 1 frame of a green background

 

 

That would not be logical option in this case. The glitches are being caused by the conversion and there are far to many to go back and use a transition to mask them.

I ma not suggesting adding in a transition. For me, there are typically around 3-5 per hour of video. I will typically add an effect, allow to background render and then remove the effect and allow to background render. This has never failed to remove a glitch (for me).

Im sorry if I missunderstood. Im not catching exactly what your doing. The glitches started at 3 to 4 per 5 minutes of video and increased the past day or so to as much as 6 per minutes of video (every 10 seconds). My first few videos did not do this. I did a system restore lastnight back to the date of my last known good video render and I was then able to do a 5 minute video without the first glitch. That tells me something changed in either studio or on my system however I have not made any changes on either knowingly.

 I tried again today and although I had the one 5 minute video without any glitches, the videos after this started doing it again. Again the glitches are every 10 seconds.

Would you be able to supply us with a sample video that has this prevailing glitch/corruption? What's the model of the video cards that were used on the this and other computers that produce this issue?

Here is a sample...  http://www.socalsurfs.com/glitchtest.wmv   Im running two Nvidia Gforce 7950 GT video cards (SLI) .  I dont have the specs for the other systems.

Are the other computers also in SLI?

No they are all single video card systems but not sure what model cards. One has an ATI, another has Nvidia and not sure about the last. Regardless trying it on 4 other computers now, besides my own, I have to believe its the conversion and not playback.

We must be talking about different glitches. Mine are different than what you show.

I also thinking the same. Let me try to look around and post here when I find something to try. Can you post the exact specs of the input video (resolution and compression used) and the the tested formats and specs that you tried. It might also be a good idea to post a sample raw clip that always end up with this glitch in all the 4 computers that you tried.

The source files are imported directly from a Sony SR11 at full quality (1920x1080). I have also tried at lower quality settings and different audio settings (5.1 and just steroe) with the same results.

I decided last night to uninstall studio and reinstall. I did another video using the same source file as the video linked in my last post. If you compare the two you can see a big difference in outcome. The first one has very noticable horizontal lines and its especially noticable when the camera pans. Not sure what is going on there as no settings have been changed. 

This is yesterday before uninstalling http://www.socalsurfs.com/testglitch.wmv

This is after uninstalling and reinstalling http://www.socalsurfs.com/test2.wmv

So my first video after reinstall came out flawless as did my first few videos on my first install. Glitches started shortly after and got progressively worse. Im going to do a few more and see if the problem resurfaces and if it does I can only think that something in Studio 11 is "breaking"  so to speak.

In addition to the above problem, if that were not enough, Im still getting the random 4:3 output. Even though the source is 16:9, the output selected is 16:9, sometimes the final video ends up as squished 4:3. I first thought starting "New Project" each time corrected this but it does not. All these issues are making Studio 11 more of headache rather than a tool. Coming back to view a 2 or 3 hour conversion only to find out the aspect ratio did not take or you have flickers just sucks. Whats worse is Im not even doing transitions and titles, just conversions.

I got three conversion that had no flicker. The first one output as 16:9. The other two output as 4:3. After this I have not been able to get a flicker free output. So the way it looks if I want a flawless video I have to uninstall and reinstall S11 for every video I do. The only thing keeping this software on my computer is I paid for it and want to get at least one full movie conversion out of it. Im moving on to the next available solution as soon as its available. So far I have not seen the use of even attempting a full movie conversion because its highly unlikey it will be flicker free and a pretty good chance it will come out 4:3 squished video. I have no desire to even begin to use the editing features since it cannot do a simple conversion to begin with.

I'll bump this up with engineering and see what they find out. Any chance to get a sample raw clip that converts to with this issue?

  Sure.. any raw clip from my SR11 (m2ts).  http://www.socalsurfs.com/00003.MTS  

 

Thanks for providing this. I'll be back with my results.

Hey Mark can you do a short conversion with this as well?

I'll try, but it will have to be tomorrow.

Thanks!

No worries, I'll be doing this on a P4 system so that might not be the fastest method as well.

I have rendered the raw clip with the following settings:

WMV
High Quality HD 720/60p 1280x720
(5Mbit/sec) with Audio stereo sound 16bit 48kHz (192Kbit/sec)

Here's the outcome.

I have rendered it twice and extended it by copying and pasting it 3x in one project. It came out with the same result as the one above.

This was created on the following system:

P4 2.4Ghz (single core)
1GB DDR 400
FX5200 128MB (lacking for HD) I had to test the output file on a HDCD system.
Windows XP SP2
Studio 11.1.2
Normal processes running and no disabled startup program.

WMV High Quality HD 720/60p 1280x720 (5Mbit/sec) with Audio stereo sound 16bit 48kHz (192Kbit/sec)

Rendered once (1920x1080 project) to wmv as above.

E6700 C2D, 4 GB RAM, 7600GT/256 MB, Vista Home Premium 32, S11.1.2.

I got 2 glitches. See here. Are they at the same times as yours? If so, I would guess it is the raw file. If not, it is likely just due to some issue with the encoding and computer (search indexer was on too?).

Thanks for lending a hand Mark. Im interested with these glitches that you found as my converted file played back normally. (I shouldn't ask while downloading the file.)

Update: Saw it. Strange. I played my version of the file but couldn't get it to do a glitch. 

I see the glitches in Marks conversion at 29 sec and 39.

I dont think its in the raw file otherwise I would get the problem all the time. I was able to do a few conversions of the same raw file without a glitch. Also note that the glitches in Marks conversion are 10 secs apart, which I have found to be the case in most of mine as well. Sometimes I might get  along convesion with just a glitch or two but usually the glitches are plentiful and every 10 seconds.

The plot thickens...

• Not an Intel/AMD issue
• Not a RAM issue 2 vs 4
• Not an OS issue XP vs Vista
• Not video card specific 7950GT vs 7600GT (both Nivdia)

 Anyone see the same issue with an ATI card?
