Not enough disc space?

WiggumSD · Post by **WiggumSD** » Tue Apr 19, 2005 2:32 pm

I've created a project on Video Studio 9 with a running time of about 1.5 hours including titles, images, video and transitions that comes out to about 5.8 GB.

When I go to burn this project, it shows that I need 5.8 GB of disc space. Obviously, I don't have enough space on a 4.7 GB disc to fit this project. So I went to the options, and changed the MPEG settings, and now it tells me that the required disc space of 3.7 GB so I figure problem solved. Nope. It still says that I don't have enough disc space.

For what it's worth, I am by no means an expert, but I have used prior versions of Video Studio with little trouble. What am I missing? Why won't a 3.7 GB project fit on a 4.7 GB disc?

Many thanks in advance.

Hi,

Computers lie. You likely have enough space, but the machine doesn't see it or can't use it.

It sounds like you are using an MPEG CODEC, and I would suggest that you edit in the least "lossy" CODEC you can. I use DV AVIs for most things.

That might be important when *Encoding* to MPEG content in the final phase of disc preparation - it will look better to encode to MPEG from the least compressed source.

A good encoding calcuator is located at:

Since you already have edited with MPEG, make sure that

You select the *gear* and in the Project settings, you check the box for 'not converting' compliant files.

Actually, if the existing MPEG files are too large to fit on a 4.7GB disk, you would want UVS to convert the files, just so they get re-encoded at a lower bitrate.

Perhaps that is the only way the poster can do it, but to encode MPEG from MPEG is not going to be pleasing.

I would always suggest using the best CODEC possible on the timeline, then encode that to MPEG2 for the disc.

I had a very similar problem not long ago: The program kept telling me I only had 2.7GB of free space, even though I deleted material on the DVD-RW, and after that reformated it! Still only 2.7GB of free space! Darn Video Studio glitch!!!

When I calmed down and looked again, I realized it was talking about my hard drive! I'd practically filled it.

WiggumSD,
When you changed the bitrate property, did you create a new video file with that new bitrate? If not, try it and see if the file size actually comes down. Then select that video file (with empty timeline) in Share/Create Disk. Be sure to manually set burn properties to match new video properties.

As an alternative, you can be the first to try the new "Shrink to Fit" feature in VS9 (see the last screen in the burn DVD sequence).

I don't disagree, I just wanted to point out that UVS' idea of what is "compliant" is flawed.

UVS 9 still has some rough edges in that area, last week it managed to create a DVD for me that contained a mixture of two LPCM and two AC-3 videos. You'd think that if the chosen template specified LPCM audio (for compatibility with computers that don't have an AC3 filter), that it would convert AC-3 audio as needed -- not so. I guess just because the video was already in MPEG2 format at the correct bitrate, it used the file as-is, even though two files didn't use the selected audio format.

After I discovered the problem with the disk I burned, I turned off the option not to convert compliant files, and was able to create an all-LPCM DVD. The video was indistinguishable from the first disk.

Hi,

That might be more that NTSC and PAL DVD specifications are different when referring to audio.

PAL can be complaint with MPEG audio, NTSC isn't.

Bummer.

Problem solved.

I actually had to go into "Change MPEG Settings" and "Customize", and change my Compression down to around 5800 kbps. It was a pain, because it had to Render it, which took forever, but worked nonetheless. I'll have to create a video file of my project to 5800 kbps to avoid the rendering issue for the next time I want to burn.

Thanks for all the responses.

UVS 9 has a "Fit to disk" option that will automatically lower the bitrate to fit the project onto one disk...

THoff,

Yeah, I tried that, but I don't think VS9 likes me too much, as it didn't work. In fact, I tried it several times to no avail. Not sure what the problem was, but I'm just glad I was able to do it manually.

Thanks.

Wiggum,
If Shrink to Fit doesn't work, please report that to Ulead Tech Support.
