Shaky blurred footage when creating DVD

Post by nealenapier »

Hi

I'm having a problem with V10 plus which I did not have with V9 (which I only had on trialware). The finished footage is very choppy and blurry on movement sequences when compared to V9, using the same DV footage imported using firewire.

I have looked through the forum and came across various articles which looked like they would solve my problem. Of particular interest were these, but they did not solve my problem
http://phpbb.ulead.com.tw/EN/viewtopic. ... 4298#74298
http://phpbb.ulead.com.tw/EN/viewtopic.php?t=20391

I also went through this tutorial on project settings andd preferences
http://phpbb.ulead.com.tw/EN/viewtopic.php?t=14542

AFAIK I am following the recommended procedure.
1 - I import a short sample of DV and put in the edit timeline. I have turned on warnings about different formats and get no warning. This is the format (I think this is correct).
Microsoft AVI files
24 bits, 720 x 576, 16:9, 25 fps
Lower Field First
DV Video Encoder -- type 1
DV Audio -- PAL, 32.000 kHz, 12 Bit, Stereo

2 - I don't bother editing anything and go to share->create video to create the complete video file. Still in AVI format!

3 - I exit Video Studio and go back in. Check all my project properties and preferences, then goto tools->create disk.

4 - I use Add Media->Add Video Files to import my complete AVI into the burn timeline. Recheck all settings and create the DVD folders. If I rename the VOB file created to MP2 and view from my PC using Windows media it looks choppy when panning. If I create the DVD from these folders it has the same poor quality when I play in a DVD player. I use maximum quality for all the settings

MPEG files
24 bits, 720 x 576, 25 fps
Lower Field First
(DVD-PAL), 16:9
Video data rate: 8000 kbps
Audio data rate: 256 kbps
Dolby Digital Audio, 48 KHz, 2/0(L,R)

Has anyone got any ideas on this? I would be so grateful. I have spent hours on this. It just seems that it is either ignoring my settings when creating the DVD. Or maybe I am losing frames when I import the DV, is that possible when capturing DV or is it impossible? I wonder about this because I did start to run out of disk space. I cleared some space and now have 40GB, but maybe I need to defragment if this might be an issue? I can't tell what the quality of the imported DV is since the file is so large that nothing will play it smoothly anyway.

My only other thought is whether 24 bits, 720 x 576, 16:9, 25 fps is correct from my Sony Digital 8 Handycam?

Regarding your last question, I too have a Sony Digital 8, but I didn't think any of them had true widescreen 16:9. So your setting for that could be one source of problems. However, I will leave that to one of our experts on widescreen to comment on.

Regarding your workflow, I am a little puzzled why, when you first go to Share > Create Video File, you choose (DV/)AVI as the output format. Why do you not choose DVD, which will produce a DVD-compatible mpeg-2.

As it is, you are then opening the burning module and inserting a non-DVD-compatible AVI, which therefore has to be converted on the fly by the burning process. This is often a source of major problems for many users.

You should first choose Share > Create Video File > DVD (using the highest quality settings), and produce an mpeg-2. Then close the project, and with an empty timeline, go to Share > Create Disc, open the burning module, and insert your new mpeg-2, build your menu and burn. That way, you should have no problems. Make sure 'Do not convert compliant mpeg files' is ticked in the second icon in the bottom left of the burning screen.

Incidentally, look up your camera manual for how to change the audio properties to 16 bit from the current 12 bit. You will get better audio quality that way -- though this would not at all have anything to do with your current problems.

Thanks Ken, that's the problem!

I'm on information overload on this subject at the moment. I didn't have to dive so deep on VS9, it just worked with minimal intervention. When I read the articles I missed the subtlety of saving video to MPEG2 instead of AVI.

I just found and read this article and that makes it clear about saving to MPEG2 http://phpbb.ulead.com.tw/EN/viewtopic. ... 1835#91835.

I now have a non-jerky DVD. I have just given myself a new problem where the clip seems to have changed properties when I re-imported it from the camera. It has all the same attributes except is doesn't say 16:9. On the test DVD the menu appears full widescreen but the actual movie appears in a letterbox in the middle of the screen.

I think I must have changed something somewhere on my capture settings. I'm sure I'll get to the bottom of it somehow.

Your correct about the widescreen on my camera. It is a simulated widescreen where it just chops the top and bottom off the picture when filming (and disables steady cam when you use it). However I don't think this is the issue as VS9 handled this with no problem.

I had a look in the manual about the sound and it says...
12bit gives 2 stereo sounds
16bit gives 1 stereo sound with higher quality

Now I understand that 16bit gives higher quality but what exactly does 2 stereo sounds mean? I guess there must be a trade off somewhere.

Top marks on this forum. There is some real quality information here. :)

Glad that you got a decent video/DVD at last.

As I say, I am not an expert on widescreen, so hopefully someone who is will jump in here quickly. But it could be that you have ticked or unticked the box on the opening screen or elsewhere in the program which changes between 16:9 and 4:3; or else chosen a 16:9 format in the burning screen.

As for 12 bit vs. 16 bit, my understanding is that 12 bit, while lower (but still good) quality, will allow you to use a second audio source instead of one (which is all you get with better quality 16 bit). You can use one channel when recording and then use the other to add music or narration later. But since most people can do this with software during the editing process anyway, it is probably better to go for the better quality of 16 bit from the start.

Thanks for that. I'm changing to 16bit now.
