HDV slow in Vegas 6

btpmusic wrote on 8/8/2005, 1:34 PM

I have captured 1440X1080 both in avi and also m2t formats via Cineform HD into a P4 2.8 with about 750 megs of Ram from the HVR-Z1. I have seen on the cineform website that this is within the necessary range to work with HD via Sony Vegas, yet the play is extremely slow, event if I use Draft (Auto) as the viewing mode. What can I do? Neither the AVI nor the m2t files are better over the other. I would prefer to keep in the m2t mode throughout, for file management reasons. Any help would be greatly appreciated.

I don’t mean to sound like a commercial... but get GearShift. This is exactly why we developed it. Forget about the CineForm files. GearShift will allow you to make DV proxies from the M2T files and then do all of your editing with the proxy files. When you are ready to render, use GearShift again to swap in the M2T files. You can swap between the DV Proxy and M2T files as many times as you want.

Also, make sure your video drive(s) are performing good. You should have drives that allow for at least 100 MB/s (The free SpeedDisk program will tell you what your data rate is). This is easily achievable with a pair of the WD740 SATA drives in RAID 0.

You Definately dont want to edit M2t files. its really a transport stream and not really good for editing. No matter what ,you will have slow frame rate on the timeline, theres many reasons for this if you do a search on this site. The Cineform interm are big files for sure, when I use them I usaully delete them after the project and just archive the m2t for storage puposes. With 2.8 gig processor you should get close to 27-29 fps on auto if you keep the preview window small, try setting you dynamic ram down to 16mb. that works for some peoples system better. If you add effects it will abviously slow down big time.
GearShift is a great way to go, lots of chioces for proxies, I often use dv widescreen allowing you to work with effects and keep frame rate up.
But beware of Vegas' m2t file limitations when using more than 20-50 m2t on the timeline- render crashes.
search other posts on this by both myself, Wolfgang and others.
But w/ GearShift you there is a workaround.
(especialy in the up coming release...... so I hear.)

the 1.5 version of Gearshift can be found

It's a free upgrade for current GearShift users. There is also a WEVA discount code up this week during the WEVA show.

Great that there is the new Gearshift finally.

What are the new features?

GearShift will now allow you to convert directly from the timeline. So many people were adding their clips to the timeline and then trying to run GearShift that we just made it work this way too. That means you can do some rough edits before you render your proxies.

Also it now allows you to render Regions. So you can go through your footage and place regions around what you want to keep and GearShift will only render those regions as proxies. (no sense converting all of the footage if a lot of it won’t be used anyway).

We also moved the CineForm Intermediate template to the HD drop down. It’s really not a proxy format because it can be used in the final render so we moved it out of the proxy dropdown.

These additions should streamline your editing task even more. As Spot said, it’s a free upgrade for existing customers so go get it! Please uninstall the previous version because we have moved to a new installer technology and all older versions should be removed first.
