VideoStudio 10 audio problem

[lata]

Hi

And good morning

This a link to the missing file rather than the folder.
Hopefully should work
Be aware that the file is 3.3Gb quite large

Hi Donald

I used Video Studio X4 and have not had a problem with your project.
I rendered the project to same as first clip, that created a new video file.
Add that to the overlay track and play, both tracks will play together the audio was an exact match to the original.
The last comments at 01:30:32:00 Looks Good is spot on.

Some observations regarding the video files.

The original seems to be 16:9 widescreen, I assume to be HD.
This has been rendered converted to 4:3, black borders being added top and bottom to achieve the 4:3 frame.

The Project Properties are set correctly for the 4:3, the video displays as widescreen because of the black borders.

Audio
Original clips….
First clip …. I do feel that the audio sync is out a little, maybe a few frames, that’s from the beginning opening scene, not really a problem, maybe I am being ultra critical.

I have not noticed any clicks or problems with the audio playback that does not show on the originals. I must admit to not playing the video throughout.

Back in Aug 10th 2013 I tested a similar video sample with no problems, Ken also confirmed this in his tests.

It could be Video Studio 10 but I doubt that, for me uvs10 was probably the best of the bunch at that time.
You could try getting hold of the X7 trial, don’t waste time trialling X8 it does not do Mpeg2?
I would suspect your pc is at fault? are you using XP?
Have you tried re-installing the operating system, sorry but that may be the next step,
Unfortunately XP is no longer supported by Microsoft so no Windows Updates will be available.

Hopefully others will test your files and find the problem, but for me they work ok?

That for testing the files Lata.

I assume that you did not use Smart Render. When I don't use Smart Render to create a videofile, it looks like the video and audio are in sync but then I always get the popping and cracking audio.

That's fine.

When playing the original clips (recordings) on my television they look perfectly in sync to me at least.

I seem to remember reading older posts on the forum regarding popping and cracking audio with VS 10 when it first came out. I wonder if it is because I am using the upgrade version from VS 9 that this is happening? Perhaps I will look for a trial of X7. Do you think X7 will keep a rendered videofile's audio and video in sync if using two different recordings (both recorded in SP mode on two different DVD recorders) but each having a slightly different bit rate? The project editing would be similar to the project I uploaded.

I am still using XP and my PC specs are the same as before. Yes I have actually re-installed XP last year, yet these problems remain persistent. On VS 9 I don't get the popping and cracking audio but am getting OOS on videofiles rendered from that very same project, even when I don't use Smart Render.

Hi Donald

I used the default settings, I used Smart Render, I rendered using same as first clip, that used the original video files properties.

I do not get any audio popping, the audio sync is same as original.

I do not have a problem with those video files, maybe others will be able to replicate your issues.

Upgrade from UVS9 to 10 is merely a licencing issue, the program is the same as purchasing the full version, you get a discount to buy UVS10, I guess a loyalty reward.
I ran UVS10 and was very pleased with the improvements especially from UVS8.
UVS9 was on a par with UVS10. No audio issues with either of these.

Audio drivers, I did a google and it appears the Realtek ALC880 Audio Driver is the one required for your motherboard, do you know if that is the one you have installed

Hi Donald

I have installed my version of UVS10 and can now see a little out of sync after rendering. Only a few frames.

The beginning is out by 2/3 frames, but that is enough for the audio and video to be annoying.

The file rendered using X4 had 165,780 frames with UVS10 having 165,780

I will do a few more tests to see if I can fix this, but your best option may be to use a newer program?

While I couldn't confirm this in Device Manager, I checked the HP website. For my computer model it states...

Onboard audio or audio card

Integrated Intel High Definition(TM) audio (Azalia)

Realtek ALC 880 chipset
THX certification support
8-channels for Full Dolby 5.1/6.1/7.1 surround sound support with Dolby Pro Logic IIx

Interesting. With my videofiles using Smart render, the out of sync issue is not really as noticeable at the beginning of the program compared to the end. From what I understand, that is typical when OOS issues occur anyhow. By the end of the program it is annoying, just as you have said.

I will do a few more tests to see if I can fix this, but your best option may be to use a newer program?

I sent a message to Corel tech support asking if it is possible for them to send me a trial version of X7.

Hi Donald

Running Windows 7 required I install the Vista Patch.

I have now installed SP1 (UVS10_SP1_5in1.exe)

This seems to have fixed some issues, at least the files are the same length.
The audio unfortunately is still OOS.

It does appear that the 163449 video clip causes the most problem, mind you it may be random.

I have now added a 1 second Crossfade to all clips.
Its rendering now, however render times are very slow.
Without the crossfades renders were extremely fast, more so than I remember when actually using the program.

I’ll update this post when the render completes.

Hi

Using a crossfade between each clip seems to have changed things for the better.
I placed the rendered file in the overlaytrack and switched to Audio View where I can view the wav form, seems the easiest to view the two clips together.

So I have managed one good video, whether other clips + crossfade will render out ok is the question.

Good idea to ask Corel for X7 to test, I did look on my PC but did not have a trial copy.

Hi

I have just completed another test rendering the project.
First I added a Crossfade transition 1 second duration to each clip.

The rendered file again showed no audio problems, Smart Render was used.
I compared the wave form from the project to the new clip which showed in sync.
Obviously I don’t understand why this should make a difference but it does.

Have you tried using Fades?

[Weeination]

Hi Lata and thanks for your efforts.

It is both interesting and odd that the Crossfade transitions seem to correct the problem. However I would prefer to not have them in the final result as I want to keep the program as originally broadcast.

Corel responded to my message two days ago. They said that the links for VideoStudio 10 have been deactivated.

I was also informed that they no longer offer a link to an X7 trial. Instead I was given a link for the trial on filehippo.com.

Before I install the trial, I needed to increase the amount of RAM I have as per the system requirements, both the minimum and recommended amount. As my computer is around a decade old, additional RAM is not readily available except through websites like eBay. Even then I was told by a local technician that if I were to install 4GB of RAM that XP may only recognize around 3GB. He also mentioned that he has about a 50/50 success rate purchasing older computer components on eBay.

I see that X8 won't even work on XP. Of course Microsoft no longer supports XP.

Therefore given the results you have had with the files using X7, I am strongly considering purchasing a new computer and then getting X8. I am in the process of looking for one now.

I assume that you didn't notice any degradation in the picture when comparing the videofile to the original files.

Hi

As an update to the render tests, although Crossfade did seem to cure the issue, the out of sync was a little strange.
Playing the video did not show any problems, well not enough to worry about, difficult to identify the problem.

Viewing in Sound View showed the wave form out of sync part through.

Seemed ok at the beginning and at the end, at the 163449 clip area about 3 frames out, however even stranger that the oos was first upstream then downstream depending on where I played from.

But as I say much improved.

I will render again using X8, this time I will be more critical in what I view.

Hi Donald

I have rendered the project using X8, unfortunately although better than UVS10 it still shows some out of sync issues when viewed in Sound Mixer (Audio View), these are extremely small, maybe one frame. Not really noticeable when played back?

But getting mixed results, some better than others, I would have expected better results, I am not convinced that the problem is 100% Video Studio, I think there is an underlying issue with the original video files. Is the original source copyright protected, just a thought?

I could upload my X7 rendered version to your sharing folder but will take some time.

Video Studio X7
I had some problems opening the VSP using X7, I think it’s a 32 / 64Bit issue.
I have managed to open ok going through X8 first.

Rendering using X7 was similar if not the same as X8

I think your best option is to install the trial X7, and if it does not work because of the ram then you can always uninstall.
When you get a new pc you can then install the trial again, giving you the trial period over again.
Its best to run X7 as it’s a little different layout to UVS10

While the out of sync issue remains, it's still a significant improvement. Perhaps it's not noticeable during playback if it is just one frame in the difference.

The original recordings are likely copy protected in their original HD format. I was told this from a representative for the company that manufactures the DVR. However the files I sent you were made from recordings onto a Panasonic DVD recorder off of that DVR. They were of course downgraded to standard definition using an S-Video cable. That is apparently the only way to record off of that brand and model of DVR.

This is the computer I am thinking of purchasing.

ASUS M32AD 3.2GHz Intel i5-4460, 8GB RAM, 1TB HDD, Windows 7 Pro.

Then I'll test X7 and TMPGEnc Video Mastering Works 6 to determine whether I will purchase X8 or the latter. For timeline editing with Video Mastering Works 6, the recommended requirement is "Intel Core i7 2.66 GHz or parallel processing capable CPU. Functions faster with a multi-core, AVX2 instructions-equipped CPU." I contacted the company to see if the specs in the computer I am thinking of buying will be sufficient in case I go with that program over X8.

Lata, before I get that new computer I am trying one last thing. I have obtained a trial version for VS 11 Plus.

So far with two videofiles rendered I am still getting OOS, at least during the end of the program. I will try rendering one more videofile but this time not using Smart Render.

Do you know if the trial version for VS 11 Plus is in any way a stripped down version of the full version or is it identical?

The reason why I ask is because all of my imported files recorded with that Panasonic DVD recorder have a bit rate of 9558 using VS 9 and VS 10. On this trial version of VS 11 Plus, the bit rate varies and is much lower. The largest file has a bit rate of 5000. The other smaller four files having bit rates of 5600, 5200, 5200 and 4500 respectively.

It was not a stripped down version but the same as the full version. Corel has only started stripping things out with the trial version of X8. I can't explain why you would be getting different rates from what you got in VS 10. How are you reading those bitrates -- by right clicking and reading the Properties box? Or from the project properties?

Regarding VS 11, IIRC there was at least one update pack and Corel eventually issued a new version which they called VS 11.5...

Hi Ken.

The lower bit rate appears in both. I first noticed the lower bit rate in project properties.

Regarding VS 11, IIRC there was at least one update pack and Corel eventually issued a new version which they called VS 11.5

I wonder if VS 11.5 would give me the same bit rates as VS 11. When I placed the largest file imported by VS 11 Plus (bit rate reading of 5000 in VS 11 Plus) into VS 10 then it reads as 9558 which seems strange.

Anyhow I rendered one more videofile but this time not using Smart Render. It took around 2.5 hours to render. This time the audio and video were finally in sync. I even compared the project (the original files) and the videofile by putting the videofile in the Overlay Track and playing both simultaneously. The audio was identical. The waveform in Sound View looked to be pretty much the same throughout, at least the parts which I checked.

Now I'd like to try VS 11.5 to see if I get the same results but with the proper bit rate reading. That version appears to be the last of the VideoStudio line for which my computer still meets all of the recommended requirements.
