ok
so i've been trying to convert vids to avi and thanks to axeman he replied to one of my fourms and said you could just use your editor to export the file to avi. so i'm hopeing someone can help me out with this. so my editor program is sony vegas movie studio hd platinum 10, i opend up vegas and draged my clip that i wanted to convert, then i clicked render as, and these are the settings that were set as default.

Save As Type: Video For Windows (*.avi)
Template: Default Template (Uncompressed)
Description: Audio:44,100HZ,16bit,stereo,PCM
Video:25fps,1280x720 Progressive
Pixel Aspect Ratio:1.000

Then I clicked the box that said Stretch video to fill output frame size (do not letter box)
And i also clicked another box that says Save project markers in media file

I then clicked save and it rendered fine, i then watched the vid and it was good quality, i then decide to export another clip with the same settings but this time after it finished rendering i whent to watch the clip and it was all glitchy, i rendered two more clips and it did the same thing, it just clitched up. am i doing something wrong? help would be great. thankx

When continuing a discussion of an ongoing topic, its best to keep in the same thread where you started, rather than creating a new thread each time you want to post. That way all of the info related to the topic will be easy to find in a single place, rather than having to search multiple threads to find all the parts.

When working with uncompressed video, glitchy playback is to be expected. There is too much data for your computer to process in realtime. However, this isn't a problem, because uncompressed video isn't intended for playback, it is specifically for editing purposes. It will work perfectly fine within your editing and effects software, and ensures that no quality is lost. Then, once your project is completed, you will want to create a final version for viewing using a delivery codec that offers much smaller file sizes.

Delivery codecs like h.264 or .mp4 offer terrific options for final playback, but aren't suitable for editing as they can't maintain quality through multiple compression/decompression stages.

thanx axeman

all editing is going fine now.
i was woundering when it comes to my final product you said about some sort of codec. when my project is finished do i just download the codec and install it or do i need to set some sort of setting on my editing software before i put the codec on?
also which delivery codec is better: h.264 or .mp4?
just woundering seen you mentioned both of them in your last post.
thanx for your help
ps: i'll be sure to post on the same fourm when talking about the same subject

I mentioned a couple of codecs as examples, but there are many other options as well that you could use. There isn't a single codec that is always best, you have to choose one based on the specific needs you have for your project, and personal preference. The two I mentioned are among the more popular delivery codecs currently, which is why I mentioned them specifically.

You shouldn't need to download and install them, if you render to Quicktime they should be available by default.

so what your saying is when my final project is complete render to mov,
i take it that quicktime and mov are the same?
so anyway when i complete it, render to mov (do i have to render it as uncompressed mov?) and after i render it the codec should already be there in default? I have one more question (sorry if i sound a bit dumb)
if the codec is set as default, how will i actually know if it's set as default?
thankx

The codecs I referred to should be installed by default. You will still always need to choose the one you want each time you render.

Yes, .mov is the file extension for Quicktime files, they are the same. If you are going to use the rendered file for further editing, then stick with Uncompressed or a lossless intermediate codec, to retain quality. If you want to create a file for viewing, then use a delivery codec such as h.264 or .mp4 that will provide a smaller file size.

Codecs are a bit complex and confusing, so don't worry if it takes you a little while to wrap your head around them.

I'm not at all familiar with Vegas, sorry. But black bars indicate a difference in aspect ratio between the footage and the export settings you are using. Double-check the exact resolution of the footage, and of the export settings and make sure that they match.

I had something similar when importing video from that Lab apps back into Vegas, although they were fine when I originally exported from Vegas and they were fine in the Lab apps.

I ended up having to import the clip into Vegas and then right-click and pick the clip properties. Changing the aspect ratio back to what it was supposed to be fixed the problem, and I've just gotten used to doing it this way now.

Give that a try and see if it works in your situation.

Good point, if the black bars are just in Vegas, and aren't rendered into the video, then choosing the correct aspect ratio for the clip in Vegas should clear it up, as alienux says.

thankyou to both of you for replying (still having trouble though)
ok so i import the video to vegas.
click on project render as,
then i render it as uncompressed avi.
once i'm done exporting i'll add effects with fxhome and render that video.
once that is done i'll open it back up in vegas and black bars will be on the side.
so i change the aspect ratio to widescreen but nothing changes.
note that the black bars are the size of acedamy ratio aspect black bars, but the bars are on the sides of the vid.
any help from vegas users or anyone that knows whats going on would be great
ps: i use sony vegas movie studio hd platinum 10

Two things you can do, scale the video in vegas, or render it out as a Widescreen avi in Effecst lab. Try changing your render settings.

You haven't mentioned where you are at as far as ensuring that the settings I discussed in my previous post are correct. If you can explain exactly where you are at, it makes it easier for someone to suggest where to go from here.
