Topic: Vegas Pro Experts - A Few ?s

Dieses Thema ist veraltet und kann veraltete oder falsche Informationen enthalten.

I downloaded the trial of Vegas 9 platinum today and managed to put together a video. I rendered it at mp4. It is 3:52 in length and is only 17 - 18mb. Does this sound about right?

What are the recommended settings for a high quality mp4 and vob?

I obviously have no clue as I'm a newbie to this area so thank you for helping :)

One more question...

how can I use an mkv video as source for editing?
 
It depends on the source of the video and the use of the finished file.

Are you editing a DVD extract? VOB or MPEG2? ITunes video?

Usually you'd set up the project settings and render settings to reflect those in the source file, i.e. resolution, aspect ratio, frame rate and approximate bite rate etc.

Your file size sounds too small for high quality, generally you’d want a file of 60-100mb for a video of that length (MP4).
 
my test file was a vob from a dvd.

how can I tell what the file settings was to match the project setup in vegas? does it set it up automatically? Does it matter I'm using the demo?

I wanted mp4 so I chose that as the "save as" type but when I played it tonight thru vdj onto the plasmas and projector it did look a tad grainy.
 
I don't use mp4 much these days now that DriveSpace has gotten so cheap. I can tell you I did a lot of experimenting with h.264 /mpeg-4 and I was a never happy with a video that wasn't at LEAST 50 megs or better in file size. I don't have newest version of Vegas but in my version the mpeg-4 template defaults to very low setting. (Frame size 320X240) and (128 bps audio). You certainly don't want to compress a video to that level for a public performance.

A nealy 4 minute video with less than 20 megs would not be a good thing. So you need to bump those if you haven't already. For the video bit rate I would generally go for about 4,000.000 or a little less depending the quality of the original. (This is all done in the custom settings area assuming your version is the same as mine)

There are many VDJ users here who know 100 times more than I do about this and probably only 2 that know less but hopefully this will give you an idea if no one else chimes in. Deciding how much to compress a video really is personal taste. I read in here all the time some people are still ripping audio at 128.... blows my mind.
 

When you import a video you can see the video details when you click on it in the media manager.

Change your project settings and render settings to reflect these.

Render using VBR, with an average bite rate of 3000-5000 and MAX of 10,000. Do a two pass.
 
Thanks Renee. I wanted to give mp4 a shot since smash is like that and the quality and sound is good but 17megs seemed a little too small which is why I posed the question what are the recommended settings for a high quality mp4 file as well as vob?

Can someone answer that question in simple/video newbie terms? :)

The other question remaining is...is it possible to use a mkv file for editing purposes? If so how do I get it to appear. I read about mkvtoolkit and extractor but I can't get that to work.

MOST original DVDs are recorded at 7000-8000kbs with either LPCM (.wav) audio or 320kbs AAC audio. If you use either of these settings, regardless of the format (mp4, mpg2, vob) you will get a virtually indistiguishable copy from your original dvd.

I rip from the DVD in mpg2 (VOB) using the "same quality" setting on my ripper which gives me an exact 1 to 1 duplicate of the DVD video. After doing my editd in Vegs (I have version 7) I render using the main concepts mp4 codec at 8000kbs video and 320kbs AAC audio. I was then compressing them using the h264 codec AFTER I was satisfied with my edits and compressing them to 4000kbs video and 192kbs AAC Audio and they are pretty damn close to the original visually and audibly...certainly close enough in a club environment no one would ever know the difference.

Like rene though, hard drive space is so cheap now I quit compressing my videos at all about a year ago.

How do I set those settings? That's where I am lost.
 
Assuming version 9 is still similar to version 7, after you have completed your editing in vegas then go to FILE>RENDER AS in the drop down for "Save as type:" and select the file type you want to use (in my case the MainConcept AVC?AAC .mp4)...if you have it I would recommend you use an h264 .mp4 type. In the right of the window select the CUSTOM button. There will be three tabs on the bottom, on the PROJECT tab in the drop down window for "Video rendering quality" select BEST. On the VIDEO tab change the "Frame Size" drop down to 640x480 (or set a custom size, I use 720X480). the bottom drop down enter 8,000,000 in both the MAXIMUM and the AVERAGE (use lower numbers if you want to compress the video). Type these settings in the "description box above so you will always have them available. On the AUDIO tab cnage the "Bit Rate" to what ever you want, remember that in AAC the audio quality is twice that of mp3 (i.e. if you typically use 384kbs mp3 the 192kbs AAC will give you slightly better quality....conversely if you use 384kbs AAC your files will be at the same file size as a 384kbs mp3 but the sound quality will be FAR SUPERIOR than the mp3. Type your new audio settings into the description box, type in a new name for the TEMPLATE and then save the TEMPLATE and then hit okay.....thn each time you want to render out of Vegas just select this template and you are good to go.
 
Jaymsy,

You also asked about mkv.

I don't believe Sony will import Matroska. (But I could be wrong, it's happened before)

I suggest converting it to MPEG-2 or 4 then you can edit it in Vegas.

~R~
 
Thanks DJ E and Renee.

DJ E...Did you get my PM yesterday?? The MainConcept mp4 custom box is grayed out. The Sony AVC one isn't though so I'm guessing I should try that one?

Renee, how do I convert?

I really appreciate yall's help. I've never done "the video thing" before..just played others vids so these step by step instructions are helping a ton!
 
Got the PM Jay, Thanks, I will email tomorrow.

As for the box being grayed out I don't know. I will PM you my phone number and if you have time on Saturday or Sunday afternoon call and i can help you out...(not too early as I work both Friday and Saturday night and sleep in those mornings.....oh who am I kidding, I sleep in every morning!
 
Hi, the mainconcept mp4 thing will probably be greyed out because it's just the trial version. I think they have to pay a license fee or something to mainconcept (whoever they are) to use the codec, so because the trial is freeware they won't let it be included. It's just a guess, but it makes sense.
 
When I called tech support yesterday they told me to use Sony AVC mp4. I did and was able to set custom settings like DJ E dictated above. The file came out HUGE but I noticed the video was a half second behind the audio. It looked fine on my computer in Vegas before rendering but last night when I played it at the club it was off and drove me up the wall. LOL I re-rendered that same video using Mpeg2 and will see how that works tonight.
 
For re-rendering mkv files to .mpg, I like AVS Video Tools ($30). I've also gotten useable results with a freeware program called "Super".

For the past two years, I've used mpg2/vob files, but I may be leaning towards mp4 for the future, because the files seem to be more universally useable, and more importantly supports ID3 tagging, which the other formats do not.
