We have no idea what program you are using or what you are rendering, so its very hard to offer suggestions. If you can provide at least some general details such as what software we are discussing, what resolution the original footage was in, and what resolution it rendered to, that would help. Some more extensive details such as more detail regarding what the poor quality looks like (preferably with a link), what render settings you used, what codecs are involved, etc. would make this even easier.

I use Visionlab Studio (which I use just for a few weeks, never done movie editing before) and an 8.0 megapixel phonecam, makes very clear shots, and highest resolution (720 480 ) For display on PC it makes no difference if settings are in PAL or NTSC I guess.

Maybe the " what resolution the original footage is
rendered to"- remark by you, is something to consider....

thanks

If the footage looks good at 720x480 before it goes into VLab, and the project settings in VLab match the footage (when you start a new project you define the ratio etc), then the problem could be the exporting?

Can you, in VLab, render a frame (hit the HQ button bottom left somewhere) soomed to actual size with the canvas set to 'full'. Does it look right? If so, the problem is the rendering.

On render, you have a load of options (containers and codecs) to choose from - what did you try? Try a high bitrate H.264 Mov, I think that's one of the options, but I'm answering you from my phone, hard to check.

If you're still having trouble, put a 5 sec clip of the original and of how it looks when it comes out, and it'l give clues which bit's causing your problems smile

Hi PDRG

you mentioned one option I got check oout to resolve the problem is:
<if the project settings in VLab match the footage (when you start a new project you define the ratio etc>
But these setting are about PAL and NTSC and because I'm still not yet to the DVD burn phase and just checkin it on the computer in divers mediaplyers this could not be the problem ?

you mentioned also exporting(-same as rendering?) and yes I think I need to tweek something cause that seems to be main cause of decreasing quality, but I already had Composite quality as High but Image Scale as Third, maybe thats the problem?(edit:was the problem at Full much better quality, only still small screen)
Also had Filetypeat:Directshow Uncompressed avi

No matter what I try to experoment withProject Settings I keep gettin a small screen
I have tweeked on Template, Widt and Heigh, Sampling etc.
No satisfying result, screen gets smaller and smaller in media player after rendering
but at least the quality has gotten better:)

We're missing something here...

I think we need to see a clip or screenshot from your original movie and the VisionLab output... Make sure when you start your project you do so with the "Select video clip" option to ensure you have the correct resolution.

You should probably consider getting the full version of VisionLab rather than the demo so it renders without the massive watermark as well.

I think I see what ou mean,
with the "Select video clip" option
I see it's possible to customise the Template and
withe "Blank Timeframe" option thats not possible
But,then why would anyone start a project with the
"Blank Timeframe" option ?

The next dialog which pops up after "Select video clip" or "Blank timeline" is the Project settings, which you can edit in both cases. The only difference with "Select video clip" is that the settings are mainly filled in automatically and your clip is already imported.

but that doen't help me to have normal display size in a media player
Funny thing though if I put in Width and Height a LOWER number and render it I get a bigger screen/ display in a mediaplyer only the movie becomes unsharp/vague
I first tried by putting high numbers in the Width and Height boxes to get a bigger screen but on the contrary it became smaller
I guess I'm confused:)
and gettin a bit frustrated too

What size does VisionLab say your video is when you import it using "Select video clip" in the Project settings?

That is a very tiny video. I see you are using a camera phone - while some phones can take fairly high quality still images, they are nearly universally terrible when it comes to video.

For comparison, a basic DV video camera has a resolution of 720 x 480 (over 4 times the size) and HD works at either 1280 x 720 (12 times) or 1920 x 1080 (27 times).

If Windows Media Player is playing the video any larger than the black box below then it is scaling the video to make it easier to watch - this might be something to do with the format it is recorded in. It may even be an option in your Windows Media Player settings. VisionLab is loading and exporting the video at its real size (not scaled).



If you import your video with "Select video clip" and don't change the sizes it gives you, then export again, I expect it appears about the size of the video above which is correct.

My phonecam can getup 740X480, which I have rendered in VL
but I get the same relatively small screen.
When I play the original movie directly (without rendering it in Visionlab) I get a normal big screen display

After rendering it's about 4 times the size of the 320X240 black screenshot you send with your reply,
but it still covers about a third of the total normal display

Please provide a link to a clip of this footage. I'd be interested in messing about with it a bit to see if I can figure out what's going wrong.

You said that VisionLab said your video was 320 x 240, not 720 x 480? crazy

When does it tell you the video is 720 x 480?

my phonecam settings are 720 x 480
and when I play an unrendered/unvisionlabbed video straight from
my phone in a media player like windows or vlc player I get a normal big display/screen (even if I have sometimes record the movie with 320 x 240 setting)
but after rendering in visionlab it has shrunk
to about the size of a 320 x 240 video (meaning about the size of the screenshot
you sent with a previous post of yours in this thread)
