If possible, could someone help me understand why my video will lose some of its quality during rendering of the project?

please describe what project specifications you are using ...

media type, source, and dimensions

project editing dimensions

zoom values applied to any media on timeline

production dimensions and file output type

Media type: WMV

Source: Citrix GoToMeeting that has been sent through the Microsoft Encoder

Dimensions: 640 x 359


Not sure how to find zoom values (where should I look?)

re "zoom values" ... did you zoom any timeline media [visual properties] to larger than 100%?

as James says below, producing to a larger size than editing dimensions will usually regrade quality

best practice is to capture, edit, and produce using the same dimensions

I hope that I am answering your question. I have three zoom values, that all zoom or expand my screen to 33%. Looks fine in the edit, but still gets grainy after rendering is complete.

OK; as I understand it, your media in project is 640x359; you are producing to 640x359

please try setting editing dimensions at 640x360, and produce at 640x360

I have seen some instances where a 1 pix change in editing dimensions and production dimensions can make a big difference

try doing a custom production to MP4 w/controller, with video quality set to 70%, and H.264 set to high

does that help?

can you post a full-screen screen capture of your project on timeline at ctl-F9 zoom?

also, could you do a quick produce and share to Screencast.com and share that link here so we can see the issue?

the problem might be some incompatibility between the WMV and its encoding, and the CS editor/production engine

thanks;

it looks very good to me, viewing in Chrome; if I full screen, it will get a little blurry, but that is to be expected when expanding so much; my monitor is 1920x1080

I even tried zooming the browser; it still looks quite acceptable

does it look bad to you? if so, what browser?

Hi. I am viewing in chrome as well. There is a section when we do a demo from our website. That sections looks really unreadable. As a side note, could you remove that link from screen cast. It is not a publicly shared video. 

Thanks

It seems all of my problems is during the viewing. 

Are there other settings I should try?

first, I [personally] cannot edit your posts; there should be an "edit" link [for you] on that post?

second, I looked at the section where the web demo is; it definately looks blurry; it looks like that section was captured at full screen, then downsized; downsizing that much will yield bad results

what dimensions are the web sections?  do you have the actual screen capture clips [at full screen size]?

if so, I would try using editing dimensions and production dimensions that equal the web capture section

you could probably zoom the power point like section to a larger size as it is just graphics?

The biggest improvement to my own publishing quality came once I was sure to make my editing dimensions match my output dimensions. If you set editing dimensions (the size of your canvas) to match the recording's dimensions, then you may get some reduced quality once you output, assuming that output is probably a larger dimension than you were editing at.

In otherwords, if you're going to output at 1280x720, make sure you're editing in 1280x720.
