Jerky playback on external monitor

VIDEOGRAM wrote on 4/14/2003, 10:16 AM
Hi,

I finally dumped my DV300 to put an OHCI card yesterday.
It went like a brease. I now have V4 and Premiere 6 feeding my external monitor.

My problem: with ordinary footage( no rendering required), the playback from V4 is jerky (something like 15 fps) but the same footage in Premiere shows perfectly on the external monitor.

Any thoughts from the experts?

Set your preview mode to Best-Full, if it is still jerky, then there are probably some parts that may need to be rendered before you can get a smooth playback.

This didn't do the job. I still have about 15 fps on the external monitor ... and no rendering required: I just captured a clip and put it on the timeline.
Although I have a slow processor (PIII 500), it should show on the external monitor at 30 fps like Premiere 6 does?
This is the only bug I have with V4.

try setting the preview mode to draft(full), see if it helps.
i do have similar problem with my P4 2.0

ALso just becuase you capture a clip and put it on the timeline, doesn't really mean that it doesn't need to be rendered, sometimes Vegas still has to render certain parts of clips.

I always thought that a captured clip, with no effect, no nothing would playback directly from the timeline as the file is the same captured. This is the way I had it for years ...

But changing the resolution of the preview didn't change anything. Still have this choppy playback from the timeline on the external monitor.

Very disappointed. Any other suggestions?

I'll try this during the week-end.

Videogram:

I have a system which is not much faster than yours (P3-600), and I can obtain full-frame playback via firewire and pass-through camcorder (most of the time) through the external monitor (as long as no FX, transitions, etc are in the timeline - these require frame recompression). Also, make CERTAIN the video levels have not been inadvertantly changed (easy to do).

Also, the KB is a good reference. Search for external monitor"

Seems strange. Primere won't even play real time preview to monitor and Vegas will. Primere won't play MPEG on timeline even on computer let alone monitor and Vegas will play both to Monitor (Mpeg is often bad with drop outs but it plays). Stright AVIs should play just fine unless there is something funny going on. Playback to monitor on my old slow Athalon 1000 is just fine.

I've still got the same problem. I'm hoping that there is a cure.... everything else is so close to perfect!

Well, I think I found the solution to my jerky external monitor problem: I have the habit of keeping the scopes open to monitor levels. When I close them, playback becomes flawless.

Hope it helps someone else.

Scopes do suck RAM. Regarding playback, feel fortunate because we bought a Canopus RES 100. Capture with the weird Canopus Storm thing, edit in Vegas, render to AVI then have to playback via Adobe 6.5 to tape. Not a major problem except the Canopus box has no slots open for a 1394 card so all editing is done with the Vegas Preview window on the computer screen. Sure am glad I got the Canopus for real time MPEG1/2 capture and the now deceased PIII 500/256 mb RAM box is being replaced with a more modern unit. BTW: Adobe 6.5 comes with this popular turnkey system and crashed (as in simply disappeared) about two hours into a simple cut project. Beats me how anyone can like any manifestation of Premiere.

Easy - it works great. With version 6.0 and up I have had no crashes or problems with editing using Premiere. But keep in mind I did not buy some turn key system, actually I use a Gateway re-maunfatured system and it has been the best PC I have ever purchased. After i got it I just upgraded the hard drive, added a generic type firewire card and some more ram. Not a problem ever on the Premiere side.

Before I get slammed - as I always have to say in a situation like this - I love SoFo as well. Love it more now with 4.0b and 24P.

Others have said this about VV and I will say it about Premiere as well - most of the complaints seems to be system based. Too slow, lack of memory, too many running programs etc etc etc. I always feel lucky when I read or hear about someone spending 3,000 - 5,000 bucks or more on a system and all it does is fail. Excluding software the Gateway was under $1,100.00 and I could get a faster, comparable, system today for under $800.00.

When DLR was still in Van Halen he told this one story that sort of applies here. The story went something like "So we were in Florida and rented this car. Man I tell you is was the nicest car we could get, but after a while it stopped working so we called the rental place and I tell them 'awww man the car won't start, the headlights broken, the left rear tire is flat, the radio stoped working and the left doors won't open.' So the guy goes 'Wow! what is wrong with it? Why won't the doors open?' and I go 'Because the car's upside down man!'

I have a PIII 450 and plays with no jerky motion as long as the original capture is not modified. A couple of important factors consider:
1. Make sure the drive that clips are stored in is a fast 7200 ATA 100 minimum.
(I have an Western Digital external firewire/USB 120G drive and works fine.)
2. You have enough RAM - 512 Mb minimum

Hope this helps!
