Garbled preview/export with AVC source files in project
-
Other than personal recordings, I have some VHS tapes that were purchased from a rental store during their closedown, which are not available anymore. My VCR didn’t have AGC and would be able to record tapes with Macrovision’s analogue protection, possible with the cards that you mentioned?
Edit: forgot to ask about GPU – planning to upgrade to nvidia gtx 700 series but heard that sony doesn’t support nvidia’s new architecture which is making lots of problems for gpu acceleration in vegas, using gpu GTX550Ti and cpu Intel i7 2600k @ 3.4Ghz, would GPU acceleration matter? With 2 working projects, I noticed both had decreases of around 2-3 minutes with GPUA on.

Hey John, have you ever came across this error message in Vegas?
==============================================
Title bar: Different depth or BPP
Description: Warning
Button: “OK”
==============================================
During rendering on one project (settings @ 8-bit for pixel format), this message
popped up several times when rendering segments where source media of color depth
24-bit(bob-deinterlaced from Avisynth) and 12-bit(original source footage) overlapped
(e.g. crossfade transition), the crossfade in the render output was glitched. The
only filters I used in AVIsynth were SeparateFields and “bob-field“,
compressed with Lagarith codec, I assume lagarith is the one saving at 24-bit
color, any way to use video source media with 2 different color depths in a single
project? -

The ADVC-300 doesn’t care about Macrovision. 😉

I don’t know what to say about GPU. You are correct that the new Kepler cards are slower than the old Fermi with Vegas Pro. It looks like AMD/ATI Radeon’s might be the best card for Vegas Pro right now. AMD has a better OpenCL implementation than NVIDIA right now and Vegas Pro uses OpenCL.

Despite transcoding media sources from delivery to editing formats, most projects I’ve done needed the GPUA off because the preview window gets messed up often, going to have a look at the CPU parking technique to try speed rendering up.
I rarely play video games, not really play but emulate the old platforms like PS1 to study on their game engines, so I don’t want to go upgrade my GPU for some features that I don’t use and if it doesn’t improve Vegas’ performance.HDDs or SSDs for Vegas use? Will it improve performance? I’m still reluctant on how SSDs have limited read/write like USB flash, Windows OS already reads/writes a lot to storage. My 2 HDDs have been running well for 8 years, considering that they have done large amounts of large file transfers.

This is exactly why I said “I don’t know what to say about GPU“. It seems to be hit and miss whether you will even be able to use the GPU you have purchased, never mind will it give you a boost or slow you down. I have a Quadro 4000 and I keep it on because it works and it’s pretty stable, but I don’t think I would buy one again just to use with Vegas Pro. Too much money for too little performance.
[Rick Anvican] “HDDs or SSDs for Vegas use? Will it improve performance?”
Only if your problem is I/O bandwidth. Otherwise it will have no affect. I’m assuming the biggest bottleneck right now is CPU performance so buying faster HDD or SSD will have no appreciable affect since most of the time you are waiting for the CPU or GPU.
[Rick Anvican] “I’m still reluctant on how SSDs have limited read/write like USB flash, Windows OS already reads/writes a lot to storage.”
I have an SSD for my Windows boot drive and with 16GB of memory, I turned off the swap file. Swap files are a thing of the past when real memory was expensive. My swap file is turned off so Windows doesn’t write anything to my SSD except temp files that running programs create. Im not worried about the life on an SSD because when it reaches it’s write limit it’s read only. So you buy a new one and copy your data over. Having an SSD as a boot drive will make Windows faster overall, not just for Vegas.

I’ll just leave GPU to do accelerated rendering in cinema4d then, the Quadro 4000 is really out of my budget.
On Vegas, the max write speed I’ve seen was 3 MB/s, back when I used FRAPS, I’ve seen write speeds of 35 MB/s (1920×1080@60). Once I had a new Hitachi HDD that became unusable but I couldn’t determine whether the cause was sustained 35MB/s writes or was it just plain faulty, replaced it with a Seagate. I don’t think Vegas will ever reach that speed because like what you said about the CPU bottleneck.
Guess defrag’s a thing of the past too, I’ve seen Vegas used up to 2.5GB of out of my 8GB physical RAM, how much would it use on your 16GB RAM?
Like I mentioned before, my current cpu is i7 2600k running max 3.7ghz (not overclocked), I find rendering speeds very reasonable considering that my projects use a lot of effects, which CPUs would be good Vegas now?

Same here. Vegas Pro only uses a few GB. I’ve never come close to using 8GB never mind 16GB. The reason I have 16GB is because I run a lot of virtual machines so I need the memory for that. But fort video editing, 8GB should be plenty.

Other NLEs I’ve tried like Adobe’s Priemere can adjust RAM usage but eats it up quick.
By the way, do you use dynamic RAM preview? How much RAM would you allocate? Currently I’m on 600MB, it would be pretty useful if you can save the DRAM preview for later viewing.(In Preferences–>Internal, what do the 2 RAM preview limits(MB) do? Haven’t touched them yet, non-64-bit is at 1024MB, 64-bit is at 32768MB)
I’m not sure if this problem affects a lot of Vegas users but I’ve found when I sometimes close Vegas after around an hour or so of editing any project, process “vegas110.exe” stays in memory with 600-1500MB occupied at times with CPU usage at 0% or 13-25%, usually I leave the process for 10 minutes to see if it closes by itself along with “FileIOSurrogate.exe” and “sfvstserver.exe”, if it doesn’t then “End Process” it is, occasional “Sony Vegas has stopped working” message pops up.

[Rick Anvican] “By the way, do you use dynamic RAM preview? How much RAM would you allocate? Currently I’m on 600MB”
When I use it,I usually set it to 1,000MB. When not using it I keep it at the default 200MB.
[Rick Anvican] “it would be pretty useful if you can save the DRAM preview for later viewing.”
Use Tools | Selectively Prerender Video… (Shift+M) to have Vegas Pro save the pre-renders as files that you can do whatever you want with. This doesn’t require any RAM preview at all.
[Rick Anvican] “(In Preferences–>Internal, what do the 2 RAM preview limits(MB) do? Haven’t touched them yet, non-64-bit is at 1024MB, 64-bit is at 32768MB)”
I don’t know but you should not be messing with the internal settings.

Yup, big problem with Vegas Pro 10.0. I don’t seem to have this problem anymore with Vegas Pro 12.0.
