Vegas Video discussions from 2004 (Q1Q2)

I suppose you could add a text generated media and paste pieces at a time. I definitly wouldn't try pasting the whole thing into ONE text media.

Edward Troxel · February 29th, 2004, 07:27 AM

It is NOT advisable to edit in MPEG2 format. This is more of a final format than an editing format. Capture through a convertor as standard DV-AVI and then render THAT to MPEG2.

If you render to MPEG, it will ALWAYS be recompressed. So you gain no advantage by capturing MPEG and, in fact, insert many problems.

Edward Troxel · February 29th, 2004, 07:29 AM

It varies depending on how you do things. If you just shorten a clip, the keyframes at the end may be chopped off. If you CTRL-Shorten a clip, they will be moved.

You can vary the curve by right-clicking the keyframe and picking from the various choices (slow, fast)

Yeah I knew I shouldn't be capturing to MPEG, but I had a bunch of old low quality VHS-C tapes to convert to DVD. Space was an issue. I found a couple of programs that won't rencode an MPEG when cutting and joining.

Thanks for the help.

Neboysha Nenadich · February 29th, 2004, 11:23 AM

heh, too bad...

I hope they will implement this in future versions.

Neboysha Nenadich · February 29th, 2004, 11:42 AM

hmmh, sorry if this is a lame question, but I did a search through the board, and I did not find the answer to my question...

why pixel aspect ratio for my PAL DV project in vegas is 1.093, but in Premiere and After Effects it is 1.067 ... The picture LOOKS the same, but is there any difference Vegas is interpreting footage?

Edward Troxel · February 29th, 2004, 01:48 PM

This HAS been a long drawn-out discussion in the past. Basically, Sony (Sonic Foundry) went to great pains to get the math correct while everyone else seems to use "common standards" that are "close".

i can't tell if your swiggles are from having quantize off or it is from the camera movement and the mpeg 1 just can't handle the info ??
now some of the swiggle i see on your posted video i've seen on clips that were dropped into TL that has Quantize off so the 1st field is NOT at a frame line .. make sure you have quantize ON before you drop a clip in TL

if quantize is ON - i sort of wrote it off that mpeg 1 just can't handle the finer detail of good ( slider at 31 vs normal 15 )

i see an improvement by doing the following .. render as mpeg 1 DEFAULT .. CUSTOM - Video .. change the size from 720 x480 to 352 x240 .. this will put the bit rate at 1,700,000 VS 1,100,000 and the I frames every 15 vs 17 .. also slide the slider to 31 ...
the higher bit rate will improve motion/movement ...

What's the story behind I-frames? How do they affect compression?

What are all the differences between an MPG Default vs MPG VCD templates?

Btw, thanks for the input!

John Zwinck · February 29th, 2004, 06:44 PM

The subject line says it all--is this possible?

Also, can Vegas make use of .PSQ or .PLB files (clips generated by other programs)?

If this is possible, how is it done, and how easily?

Thanks.

Rob Lohman · February 29th, 2004, 06:56 PM

The VCD template just takes certain restrictions (like resolution,
datarate etc.) into calculation to make sure your MPEG will be
compatible with the official standard. Personally I always render
everything at best.

Rob Lohman · February 29th, 2004, 06:58 PM

To the best of my knowledge none of this is possible. You might
perhaps export an EDL from Premiere and load that into vegas if
both support it.

Peter Wright · February 29th, 2004, 07:19 PM

Don't drag the scroll bar - just drag the cursor across the Trimmer display, and you will see each frame as you pass it.

(The mouse wheel is the best way to zoom in and out of Trimmer and Timeline)

Fernando Vidal · February 29th, 2004, 07:35 PM

Hi, I have just recorded voice over using the looping/takes technique that I learned from Spot's book, what a great feature. From what I've seen, this creates an audio file with several regions, one for each take. Now, when I put the audio event on the timeline, the event is fully extended with all the regions instead of presenting itself as an audio event with several takes. Is there a way to drag this audio to the timeline and that vegas recognizes it as an event with several takes? thanks!

Jeff Toogood · February 29th, 2004, 07:37 PM

Ok, that makes sense.

My next question, does Vegas do anything in particular when printing to tape that is superior to other programs?

I can use DVIO to send the file back to the tape and it is super simple and quick, just press record on the camera and send the file and then stop record after it has played.

Is there any reason why I shouldn't use DVIO to send DV-AVI files back to tape?
