X5 rendered footage is now suddenly jerky

[stormcab]

I'm just going to supply a small clip via Youtube to see if there's a quick fix to my problem, basically my 24fps footage isn't rendering smoothly ON X5 Ultimate.

http://www.youtube.com/watch?v=OKP_DWr1 ... e=youtu.be

What i've done is put the same clip together twice, as strangely the first clip is smooth, then subsequent clips are all jerky. This has been going on for some time, so switched to 25fps. 25fps from my Canon 5D MKII wasn't as good as 24fps, so switched back and decided to try and sort this out.

I have been through multiple settings, deleted all older versions of Corel, removed then re-installed X5, made sure all patches and updates were installed - made no difference.

I can supply all the settings if necessary, but I thought i'd start with a quick post to see if someone knows if it's an obvious problem.

Thanks

Hi

Yep the sample does show the second section as jerky, Hmmmm, seems strange that it only affects the second section.

Although I own a Canon 7D which will create the same video type, can you provide the properties of the video so others may see, right click the clip in the timeline , select properties, what are they? do the same for the rendered file.

Canon use H264 Mov, unfortunately Video Studio does not read this correctly, so when you view the properties the compression line is empty.
You will not be able to replicate the H264 Mov using Video Studio.

Tell us what are you trying to create, a video for the internet or a DVD?

At the moment I just want to put all my clips into one watchable file after a day of filming - holiday, birthday, slideshow. I want it HD.

I actually don't use the footage straight from the camera, I convert the files to avi using Cineform Neoscene - the industry standard (so they say).

Another problem that has now arisen after the re-install - X5 now crashes at the end of rendering something to BluRay format. It never did that before.

There's no point also giving the details of the rendered file, as I must have tried 50 variations in the settings, all with exactly the same results.

Have you tried using the video straight from the camera into VS instead of using Cineform?

[stormcab]

Firstly I did this 3 years ago when I first bought the camera, but the footage always rendered with jerky footage then. Now if you try to open a MOV file, it says "download Quicktime to continue" even though I have Quicktime. Either that or "File format mismatch cannot open.

Could you perhaps make a short, original clip direct from the camera availalble to us for download (not through youTube)?

[stormcab]

Definitely. Where could I put the clip up? remember though I am not using the files straight from the camera as they are MOV, they are converted to the above avi video format.

On another note, i've just downloaded a trial version of Sony Movie Studio HD 11, and did a test - it has rendered perfectly smoothly. So the files don't appear to be the problem, it appears to be Videostudio.

2 sites that I have used are : http://www.upfordown.com/ and http://www.4shared.com/. There are many other sites being used by members in these forums.

What version of Quicktime do you have? Does the clip play directly in Quicktime?
You could also change the "mov" extension to "mpg" and try it in VS. In many cases this seems to work.

We would want the file straight from the camera since you should be able to use that directly without any conversion. I get HD mov files from my Canon digital camera and I have no problems using them in VS

Hi stormcab

It would be good to see your video files.

Can you confirm that the original video file from the camera used 23.976 fps, I assume so.

Being in the UK I chose to use the 25 fps option for my camera recordings, mainly because I would be creating a Pal DVD that uses 25fps.

[stormcab]

Yes the files are that framerate, as listed in the file detail above. I have found the 24fps is a better quality footage, and is smoother when panning. In today's tech world I find there's no need for DVDs or BluRays. Everything can be watched on an HD TV via a laptop, or on a tablet.

Like I said, I have just rendered it with Sony Vegas and it played perfectly smooth on both Windows media player and Centre. So the problem definitely appears to be with VS. I could just go over to Sony Vegas, but then I wouldn't be about to tansfer any previous editing files over - like footage that painstakingly synced with audio. I also like the interface with VS, it's layout makes it very user friendly.

Hi

As Canuck asked, can you make a sample available for download, then we can run the video through our program.

[stormcab]

Ok this is the MOV file straight from the camera

http://www.upfordown.com/files/download ... I_7080.mov

and this is the avi file converted via Cineform Neoscene

http://www.upfordown.com/files/download ... 80-001.avi

I chose this file as it involved a small pan which will clearly show up the jerky effect once rendered.

Please note I have deleted all the MOV files from the 3 years i've had the camera, and kept only the avi versions, as I didn't want 2 of everything clogging up my hard drives. So I really need to the avi to be the file type to work with. I downloaded Adobe Premiere Elements 11 and the files rendered perfectly fine through it.

Thanks

FWIW, I get the same problems as you with the original .mov file -- though otherwise I have no problems with mov files more generally. In fact, even having two copies of the mov file in the X6 timeline still showed some jerkiness in the first clip but much more in the second.

Unfortunately, after a very slow download of the avi file, it turned out I couldn't do anything with it. The Properties > Compression box said this was not accessible. And when I tried to insert the clip into the timeline, i got a 'Media unreadable' message. I downloaded the file again (again taking a long time) just in case something had happened to the first download, but I got the same message. I suspect it is because the relevant (Neoscene) codec is not installed on my computer (but see below).

I also confirmed your test with Sony Movie Studio -- though version 12 in my case. It worked perfectly, as it did on both Cyberlink PowerDirector 11 and Magix Movie Edit Pro 2013 -- so quite obviously something is not working correctly in VS with the .mov file at 24 fps. But what it might be is another matter... Sorry.

Curiously, I got the same inability to play the avi file with both Cyberlink and Movie Studio. The latter simply refused to allow me to drag the file to the timeline, whereas Cyberlink returned a long message saying essentially either that the file was damaged or otherwise corrupt. However, even more curiously, Magix played it perfectly well. But if Magix has access to some relevant codec, I would have thought the same codec might have been available to the other programs.

Hi

Well I have managed to download the Mov file, looks like standard Canon file, it would use H264 compression, however Video Studio does not recognise that format H264 and Mov that is. This has been brought to Corels attention in the past, whether they do anything about that is debatable.

I am able to play the file ok using Smart Proxy, well it seems ok.

Downloading the Avi failed a few times, I will try again but is taking a very long time???

[stormcab]

Yeah once it is rendered to Cineform avi, it usually triples the file size, so will take a while to download. Maybe you do need the codec on your computer. There is an option in VS to render straight to Cineform codec, but it gives the same jerky results. Curiously, if I go to render and choose "same as first clip" it goes to do it at 30fps NTSC! VS really doesn't like these files. It was several people on this forum that directed me towards Cineform back in 2010 when I got the camera, and it works perfectly well on 25fps clips, AND, AVCHD clips that I took using an HD Panasonic camcorder. Cineform told me the program was specifically tailored for the Canon DSLR files, not AVCHD, so amazing it could still convert them. Videostudio's problem is obviously the handling of 24 fps.

On another note, I noticed with the Sony Vegas, the HDV 1080 I did a test render in, was actually 1080x1440, not 1920. I couldn't say I could see a difference, but I did then try a BluRay m2t setting at 1920x1080 and there was no sound! Looks like the only thing i've tried that has rendered properly is Adobe Premiere Elements 11. I have also noticed that Adobe will accept the MOV files without conversion to avi. So this will in the long run save me a lot of hard drive space in converting.

Oh well, i'm sick of mucking about with VS. As it's less than a year old is it possible to get a refund because it doesn't work like it claims to? I downloaded it straight from the Corel website?

Thanks for all taking the time to look.
