Playback performance issues in V7.

Justin Young wrote on 9/12/2006, 5:59 PM

Sorry to open yet another V7 thread.

Just downloaded the V7 trial, opened up a PAL Widescreen DV V6 project I have been working on as a test. I am only getting 12-13fps playback. Back to V6, 25fps without a problem. Anyone else noticed any playback issues? I will check my settings again when I get home from work. Using the default V7 settings at the moment. Not using the new preview scaling feature or an external display. Preview window is set to Preview (Full) in both V6 and V7. I can't think of what setting might cause this kind of problem off the top of my head. Of course V7 may have introduced something I am not yet aware of.

I noticed a reference in another post to lowering the number of rendering threads on older PCs. Will try that and see if it makes a difference.

I'm using Vegas 7 on a very fast PC and have just seen an MPEG-2 file dropped onto the timeline (no edits or filters) drop to about 5fp/s playback.

In a word, terrible.

I closed and reopened Vegas and the same file now plays back at the correct frame rate. It must be a bug or some other sort of hiccup.

SR? - "Just downloaded the V7 trial, opened up a PAL Widescreen DV V6 project I have been working on as a test. I am only getting 12-13fps playback."

Did you go into Project settings and change from the Factory default - NTSC - to PAL WD?

The default settings in a brand new Vegas 7 are NTSC - I think here Grazie is right.

Generally, with a brand new version it is always worthwile to check the project settings - I also had to change that to PAL Widescreen for my 16:9 PAL projects.

Yeah, Wolfie - I've embarrassed myself on more than one occasion when demoing in front of people - from a newly installed version! One time I had 25 teachers in front of me .. all sourcing PAL media at the Factory Default of NTSC . .. well, just shows the FIRST virtue of Vegas - that it being Format Agnostic!

Woulnd n't it be wonderful if one could export settings to a text file. Shear bliss!!

Yeah, that was the first thing I checked. It carried over the Properties from the veg file. I also created a new WS PAL DV project and imported some footage with exactly the same results.

Just opened the HDV sample from my V6 disk and am getting between 13-17fps playback using the Draft (half) setting and 7-9fps with Preview (half). I was getting 29fps using Draft scaled to half resolution in V6.

Can you tell us something about your PC?

Justin Young wrote on 9/13/2006, 9:00 PM

Its a fairly old PC now.

Athlon XP 1800.
768MB PC-133 SD-RAM.
80Gb System Drive.
2 x 120 Gb 7200RPM IDE HD set up as Striped RAID 0 array.
Generic Firewire card. Unsure of brand.

Its done me well for DV projects for a few years now. V7 may trigger an upgrade frenzy though. Keen to get into some HD projects.

I should point out that I have also logged a support job with Sony. I will let you know if I hear anything.
