Prerender issue
 

Good afternoon,

Well, all was well this morning until I went to prerender a 45 second series of 3 clips that that had been heavily processed. Wanting to see them in real time I highlighted them and hit shift B. the it rendered in a few seconds, impossible. I looked at it and what had happened was the loop points jumped back to the front of the clip and were 3 seconds apart, weird!!
I then highlighted, made it a region and then hit shift B and it did the same thing.

I tried maker larger and smaller ones in differnt parts of the track and it does the same thing.

am I missing something simple here?


thank you.

Dale, this won't solve your pre-render issue but it would be a workaround: I personally don't use pre-render, but instead mark a region and do a full render in a avi or highest quality wmv file. I get a better perspective than watching throught the preview window. For faster render I render to mpg if I don't need or want to hear the audio.

Dale, you're confusing RAM render (Shift+B) with Pre-render (Shift+M).

RAM render is totally dependent on how much RAM you've assigned to this task.
The setting is found in Options - Preferences - Video.

Pre-render renders the section to a folder location that you set in File - Properties.

Jeff,


that is a good idea and I have done that the odd time when using programs like Neat.

I just thought it would be easier this way.



Mike,

Vegas says i have a gig available for this (this old machine has two gigs of ram). If i move it up farely high it says it will cause a paging issue that will slow down preview.

what would be normal usage>??

Dale, I've got 2 gigs as well but Vegas Pro 8 (XP Pro SP2) will only let me use 1 gig at the most.
I generally leave this set to 128 MB for render purposes.
If I need to do a RAM render, then I'll bump it up to 1024 MB.
Render threads are set to 4.

I don't have paging issues as I have 3 drives on my system and don't use my OS for paging purposes.
I also let Windows manage it for me.
I know that some folks say to do it differently but it hasn't given me any grief doing it this way.

That doesn't sound like you did a pre-render... it sounds like you did a render to RAM.

Pre-render (where it writes outa full AVI file to the temp folder) is Shft-M, right?

That's correct Jason.

Good evening,


In prem pro when you arre done doing some fx or cc you just hit enter and it renders for you and will play real time.


All I really want is to have it rendered on the time line so it can play at a full 29 frames/sec. it would also seem that it should hold this render , provided it is not changed, so that when you render the whole project later much of it is already finished and reduces render times as well.

I reckon the ram render is only temporary, can I do it as I mentioned above??

thanks

Dale, look up pre render in the help files, it will explain it pretty well.

Yes, this is what prerender (shift-m) does, exactly. And you're right, ram render is very temporary.

AND ram render is limited to the amount of physical ram available, where as pre-render, is jsut raw AVI files stored in the temp dir.
