Choppy video when panning after render

[thegasgranny]

Hello,

I hope someone can help me here as I've spent many hours trying to sort this out I'm using VS x5.

Basically, I have a Sanyo HD camera which I've used to capture quite a bit of holiday footage. I've edited some together but when I output the project to either mp4 or mts the picture is choppy when panning.

The camera was set to 1080p @ 30fps (there's no option of 25fps even though the camera was bought here in the UK) which I have matched by choosing the "Custom" option when creating the movie. I've matched the bitrate (16789bps on the source) but this ends up being 15540bps on the output file. (??) According to the properties on the source file it's 29.97fps which I have also matched in the Custom settings option.

I understand I should expect dropped frames if I was trying to output the file as PAL compliant, but I've got VS set to NTSC so I don't think this is an issue.

The source file is mp4 and looks fine when viewing the panning scenes.

Can anyone shed some light on what I'm doing wrong?

Many thanks in advance.

TGG.

Hi TGG

And welcome to the forum.

There have been a few posts relating to panning and the Sanyo, and Ntsc v Pal
I did a search of the forum and found this post

http://forum.corel.com/EN/viewtopic.php ... o+ntsc+pal

Can we assume the camera is a NTSC model, I ask as we had some posts referring to Pal cameras producing NTSC video.

Can you give us the properties of the original video file, right click the clip in the timeline and select properties, You can copy the window as an image and attach to your post, or simply type in the details.

Do the same for the rendered new clip.

Now tell us what you are trying to make, a DVD or a video for the internet?

You do appear to be doing everything correct but maybe its just a setting that’s wrong.

Hi Lata,

Thanks for the quick reply

It's a Sanyo Xacti CG10 See here for specs: ---> http://www.play.com/Electronics/Electro ... tails.html

I believe it must be the NTSC model as it gives me only 30 or 60 fps to capture in.

Here's the video properties...

Original MP4 https://mega.co.nz/#!kIBAWYIB!AvMPQyX0q ... uJWYa4GQSY
VS Rendered MP4 https://mega.co.nz/#!FJJTUTRA!BrxSlUM_u ... 6XXOTUYpMw

I'm just trying to produce an MP4 that will play on my media center, but I'll also want a DVD copy once I've got this issue sorted.

Many thanks again.

That's an incredibly cumbersome way of posting those photos. You can post them much more directly using our own Upload Attachment function which can be found in the tab next to Options directly beneath the window where you type your posts.

More to the point, though, the images you posted were taken from Windows Explorer and tell us nothing really. Please follow lata's instructions and right click on the original and the rendered clips *within either the Video Studio timeline or library windows* and then take an image of the Properties box.

I sort of expect, though, that we may find that though your original video is NTSC, you are outputting using a PAL template... Or did you use Share > Create Video File > Same As First Clip?

[thegasgranny]

Oops! I didn't see the upload attachment button :-S

I'm 91% through rendering the video as an NSTC DVD to see if it's smooth all the way through. I tried this with a small clip first and although the quality wasn't HD, it's more watchable as it's not choppy.

I'll post the video properties from VS in the next 30mins once the render has finished.

I tried doing the Share > Create Video File > Same As First Clip but VS just complained about the size being different (???). I tried to find what the error meant but I couldn't find anything useful. I've changed the project properties to NTSC and the output file says it should be 29.97 fps.

I hope you are right and it's just a setting somewhere.

Thanks and sorry for the mixup.

Hi Ken,

The DVD has just finished and it's much smoother.

Here's the source file properties from within VS:

Source:

Rendered:

Hmm. There's some differences. What do you think?

Thanks.

I do not see a difference between the original and the rendered file properties.

The 3rd properties image is of course from something completely different. What is it supposed to be ?

[thegasgranny]

If i do render Same As First Clip on a single mp4 on a new project, I get the specified output as:

NTSC drop frame (29.97 fps)
MPEG-4 Files
24 bits, 1920 x 1080, 29.97 fps
Frame-based
H.264 Baseline Profile Video: 14695 Kbps, 16:9
48000 Hz, 16 Bit, Stereo
MPEG AAC Audio: 256 Kbps

Which I think is right.

But then I get this error:

Thanks.

Sorry, it's my first time uploading images and it's gone a bit odd. The first image is the source and the third image (the attachment rather than inline image) is the rendered file properties.

Thanks.

Hi TGG

The properties you show seem similar but the last image shows using H264 Main Profile.
The H264 Baseline Profile is not available using Video Studio and 1920 x 1080 frame size, hence the error message you are seeing.
Camera manufacturer do tweak the video codecs for their needs leaving the video editors to play catchup.
I do not know if this is a Video Studio problem or the camera manufacturer wrongly using that combination, (H264 Baseline and 1920 x 1080)
Certainly video studio does not seem to read the properties correctly giving the difference in Data Rate, when doing “same as first clip”.

OK, hope that makes sense…………..

As you mention requiring a DVD then you should try converting the video to Mpeg2, that is the type of file used to burn a disc, it will also play on the pc.
However you will have to make a template as the file is NTSC.
Using Settings - Make Movie Templates Manager create a template using these settings.
If you haven’t used MMTM before, some info here may help

Hi Lata,

Thanks for the reply

I now understand why I can't render the file as "same as first clip" which would have been ideal.

Thing is, I'm unsure what to do now. I'd like a HD and DVD version of the video but all of the HD options I've tried leave me with a choppy movie

What would you do?

Many thanks.

Hi
Are you able to upload a sample to a sharing site, SkyDrive is free, allows for upto 2 Gb. 4Shared is another option.
But a short original sample may help as we could test the video for ourselves.

If you need DVD disc then you have to use the settings or similar settings I gave earlier (Mpeg2) I assume you mean a standard DVD and not bluray.

It may be that you will have to use a video converter to create a more editable format?

[thegasgranny]

Hi Lata,

Again thanks for the reply, I really appreciate everyone's help with this

I'll upload some video tonight when I get home from work.

Thanks.

Hi Lata,

Here you go, a couple of slow panning source files taken from my Sanyo CG10.

I see what you mean after downloading your clips. Nothing seemed to work. The nearest I got was using Custom then choosing mpeg transport stream, set to produce AVCHD. It was fairly smooth -- much smoother, say, than using mp4 -- but still had little jerks not visible in the original clips.

I recall that when the standard definition Xacti models first appeared on the market several years ago, it turned out Sanyo had tweaked their mp4 codec(s). The same could still be happening with the high def versions. So can I ask if the camera came with an installation disc? If so, did you use that disc? It could contain the relevant mp4 codec...
