Clips Collection for Broadcast

garo wrote on 10/31/2006, 11:04 PM

The news broadcast folks want me to group my .avi clips into one single file. I drop short clips into Vegas, each no more than say, 20 megs. Four or five together (about 10 seconds) gives me a file size of over a gigabyte!! This isn't practical since I need to send larger clips ovewr broadband and it would take days to send proper length of clips.

What to do?

TIA! Garo

DV is 13 GB per hour or about 225 MB per minute. If you're working with 20MB files, then they are very, very short. clips. If you're rendering to DV, then 10 seconds shouldn't be more than 50 MB.
To what codec are you rendering.

I loop the clips then Render to "Video for Windows" Default Template (uncompressed)
Gettiing ENORMAS files!!
Stupid thing it the silly Microsoft MovieMaker did it brilliantly ...

"uncompressed" - bit of a clue there?

not for me - but I'm in the dark here - uncompressed shouldn't be any larger than what the originals are together or what do you mean?

The originals probably are compressed. If the source footage is DV format, it is much smaller than the "uncompressed" avi format. We tend to think of DV as being uncompressed -- compared to MPEG -- but DV video is compressed as it is encoded. The difference between DV and "uncompressed avi" is kind of like the difference between a JPEG photo and a BMP (bitmap) photo.

Try using the NTSC DV template (or PAL if appropriate) -- widescreen or normal as needed.

I do the same thing for a local cable co. What I found best is to render to MPEG-2. The final broadcast image quality is VERY good and my 30 minute TV production is only 1.7 GB in size.

I don't have the luxury of actual render times in this case. As I mentioned the silly XP MovieMaker does this just fine - I place all ther clips on the time line and "Save as ..."
No render times and comes out .avi just like the producer asked for. Go figure, must be a Vegas way of doing the same thing?

What codec is used for the original files? Do you have the same output settings for Vegas that you have for Moviemaker?

I am capturing from a Canon XM2 - you don't see any settings in MM - "Save as .avi" - works super! :-)

no other suggestions/tips? Can MM really do this better than Vegas?

IF you are capturing from a DV camera, then the output of Vegas should be a DV AVI. Anything else it will have to render. You mentioned in an earlier post that Vegas was creating uncompressed files. If you are using DV AVI files, you don't want uncompressed or it will have to rerender.

MM is probably defaulting to a DV AVI file.

XM2 is a miniDV cam (PAL format).

If your video is untouched -- no color correcting, no overlayed titles, etc. -- and you "render" using the PAL DV template, then your output file should just be a copy of your source files, joined together. I believe Vegas handles this almost like a file copy (source DV to output DV) -- should be pretty fast.

avi default no ,,dv yes

.AVI is a wrapper than can contain different codecs.

You don't want uncompressed because that gives you enormo files. You want DV. You just need to choose if it is PAL DV or NTSC DV.

DV is a compressed format. In the camera the files are compressed at a 5:1 ratio.
