VideoStudio :: Smart Proxy Slow And Not Fully Using CPU And Disk?
May 26, 2012
Given my problem with jerky video in VS4 (see this thread), I decided to give Smart Proxy another try and switched it on. To my dismay, not only does it take ages to render the proxy videos, but the computer seems to be rather underused during rendering.
VS4 took two hours to create the proxy of a 20-25 minutes 1080p file, 4GB in size. During this time, according to Task Manager, only four of my eight CPU cores are significantly busy (though still below 50%), and disk I/O is in the area of 6-700kB/s for either direction. I took care to put the proxy directory on a third disk - away from the operating system and the source videos. 25% of the 8GB memory is used.Would the smart proxy rendering process make more efficient use of the available resources, it wouldn't take half the time.
VS4 configuration
VS4 service pack 2, version 14.2.0.23
Hardware acceleration is set for both editing and file creation
The video material is 1080p, 59.940 frames/sec, variable bit rate (max 26000kbps) and comes from my Panasonic camcorder. I used the tool that came with the camcorder, HD Writer AE, to copy the files to the hard disk. Audio is Dolby, 48000Hz, 256kpbs (I have no problems with audio).
Project properties:
NTSC drop frame (29.97 fps)
MPEG files
24 bits, 720 x 480, 29.97 fps
Upper Field First
(DVD-NTSC), 16:9
Video data rate: Variable (Max. 8000 kbps)
LPCM Audio, 48000 Hz, Stereo

HD 3000 integrated graphics
OS is installed on a 128 MB SSD
Project target file is on a 500GB WD Blue.
I have ripped a Blue Ray DVD as an .m2t, at an average bit rate of about 18.5 Mb/sec, with a resulting file size of over 16GB. Needles to say this file bogs the machine when not running the proxy. When I finish a session and close the program, the proxy file is gone the next time I open the project. The same thing happens when the machine goes to sleep with the project open. I have to either slog through working directly on the project without the proxy while it slowly rebuilds, or wait a couple of hours for the rebuild to complete.
Any way to stop the file from being deleted? I went to power options and selected never, but the next day it was gone again.
Another thing would be to increase the speed of the proxy creation, as it only uses about 20% of the CPU. Better to get it done faster... I have tried raising the priority of the process to high with little if any change.

When I ingest tape, I always turn off as many resources as possible, internet, virus, etc. When capturing with videostudio pro x5, if i select smart proxy prior to capture, i get skips that appear like dropped frames. If i turn off smart proxy, then capture, than start smart proxy queue, all is fine.

Is there some reason why Smart Proxy files would not be generated with .MOV files?

Using Smart Proxy ,to show the Smart Proxy have been created , a small double icon is placed within the thumbnail in the folder and also in the clip on the timeline . The clips in the project are playing smoothly. But when I close the project and re-open it later on, I notice that the small double icons have disappeared and the clips on the timeline are no longer playing smoothly but jerky.It seems as if they are no longer smart proxy files although they are still in the Smart proxy folder.

I have heard it takes some time to make a smart proxy file, It seems to take a very long time although I dont know what is reasonable with my computer, intel2.2g proc-4g ram-64bit-win7. The files are h264 mp4 720x1280HD 60fps. Is it because they are mp4 files? I use WMM6 and have to convert to .wmv but editing is fine afterward. I have also tried Video Pad and there seems to be a short wait for loading but nowhewre near as long as VS. Is there a better format for Video Studio than mp4.

I did some filming today, using my Canon 5D MK II, converted the MOV files to AVI using NEOscene, then ran them through smart proxy in Videostudio PRO X3. When I started editing, I noticed some files were causing the project to freeze and stutter on playback. On closer examination I noticed that about 10 of the 40 or so files had not had smart proxy files created, and that all of these were above 1GB in size. Is this a glitch, or is it just something Videostudio can't do for files that large?

I've been a happy user of VideoStudio for a while now, up until the X2 version. Hesitating on upgrading to X3, I tried the trial version on his launch (now expired and removed, so, I can't speak for the latest SP version). Reason I decided not to upgrade, aside from the apparent lack of really new features from my point of view, is the smart proxy configuration, which seems to have been downgraded.
When overtime I started editing HD videos, I decided to push smart proxy in VSX2 to best fit my needs. For that I evaluated the speed of the various codecs available, and came to the conclusion that the free commercial DivX codec (which really doesn't have my preference for any other purposes), configured in low quality settings and reasonable res, was the perfect candidate to generate my proxy files (poor rendering quality but fine for editing, and amazingly fast at generating my proxy files while taking the best out my quad core CPU). For the final rendering I could then use the compressor of my choice (x264 in general).
Did I miss something, or has the possibility to manually select the codec and compression settings for smart proxy simply disappeared in VSX3? Has this been corrected in a SP since the initial launch, or is there any plan to change that in future update?

As I updated to a new camcorder (Sony HDR-CX130) and computer, I have a question about VS X4, that I am using.VS X4 is presented being a kind od ideal editing HD/AVCHD. I started to edit my MPEG-2_TS files with the presumption that I really was editing in HD. It goes quite well on my new PC, without Smart Proxy turned on! In the future I want to burn them on BlueRay-disks. Therefore I want to save my new projects in HD-mode.
But then I took a Look at the Project Properties and it is defaulted to MPEG-files 720x576 pix; SD-resolution. It seems that it is not possible to insert a Full-HD template or Full-HD-matching parameters. Media-type can't be changed to anything else then PAL-DVD.
One other issue then is that I use to use slow-motion and stills in my video-projects, for action-shots. Then I saw also that the stills (Snapshots token using 'Edit>Snapshot' (Correct? I use the dutch version)) don't have 1920x1080 pix, but 1024x576 pixels instead.
I searched the forum and found this topic about the project properties vis-a-vis HD-editing: URL....As far understood, the projectproperties don't matter that much, all material will be rendered Full-HD (upscaled?) in the share-step when selecting BluRay-disc or AVCHD-Video File. Then my questions:
- What is then the use of Smart Proxy and the Project Properties-Dialogue?
- Will the stills be upscaled, so they integrate seamlessly in the endresult?
- Is there a way to change the videostill/snapshot resolution to Full HD?

I have VS 12 installed on Windows 7 computer. It worked so far fine, but yesterday evening I wanted to upload my mpg files from the hard disk to the library. And guess, the system is very slow, it took almost 20 minutes to upload about 10 mgp files, after each file nothing happened for almost 2-3 minutes. Each clip is about 10-20 sec long. The files are stored on an external hard disk (Buffalo 500G) which is connected via USB 2 interface. It did not do that before, it was much quicker. Could it be the recent Windows updates?

I've been using Video Studio X2 with proxy enabled to edit my HD video.When I had my HD video files on USB hard drive connected to my laptop, everything worked fine.Last week I bought a QNAP NAS to store my files and share them throughout my home network. My HD files are now stored on this server.My laptop connects to QNAP through a WiFi router with real maximum bitrates of about 20Mbps (DVD video files have bitrates of about 10 Mbps).
I've created proxy files stored on my laptop local hard drive.My playback method is "Instant playback"
2. Problem:When I play a clip that as a Proxy file associated, Visual studio connects to QNAP and tries to download a large file (I suppose de original HD video file).Connecting my laptop to QNAP by Ethernet cable and monitoring download bitrates, the result is 40-50Mbps (in line with HD video file bitrates), above WiFi speed!Connecting my laptop to QNAP by WiFi, Visual Studio plays with annoying frequent gaps!!Why does this happen? Is not proxy file intended to play instead of the original file?I supposed that playing a video clip with a proxy stored on my hard drive, Video Studio didn’t needed to download anything from QNAP!

that is having really slow performance using AE CS6 or AECC and possibly AE CS5.5 I think i might of found out what the problem is.My System specs are below:
Dell T7600 Dual XEON E5-2687W 3.1/3.8GHz w turbo / Dell M6700 i7 -3940XM 3.9GHz
64GB Ram / 32GB Ram
Nvidia Quadro K5000 / Nvidia Quadro K5000M
Windows 7 x64
Here are the issues I was having
- Really slow performance when scrubbing along the timeline.
- Adaptive Resoltion wasn't working at all super slow previewing
- Multiprocessor rendering not working, or taking forever to start up, and sometimes it would work but still not the way it should it was hit or miss
- Disk Caching not working
- many others that I can't think of at the moment
SOLUTION for slow scrubbing of the timeline for Quad, Six and Eight core systems
Here is what I figured out after hours and hours of testing and configuring. I even went back to AE CS5.5 to see if all these problems existed in that version. Although some did but not all
From what I can tell it looks like certain plugins are not compatible to Quad, Six and Eight Core machines. The main plugin that has the problem is Keylight 1.2 that comes bundled now with CS6 and CC.
If you turn off the plugin on your layers scrubbing the timeline speeds up and works like it should. If you want to use keylight then do the following:
- under screenmatte, set the screen softness to 0
- shrink and grow to 0.
If you use any number other than these settings it causes scrubbing and rendering of the timeline to go extremely slow.
SOLUTION for all the issues above for Quad, Six and Eight core systems
After hours and hours of testing I have come to the conclusion that AE CS6 and CC don't work well with Quad, six and eight core systems in general and especially with the keylight plugin.
FIX: Go into your Bios of your computer and set your multiple core to either 1, 2 cores, theis will give you 2 thread or 4 threads. This will fix all the issues as stated below. I haven't tested 4 cores yet but soon will.
But I know that 6 and 8 cores definitely does not work it causes all the major issues above.
After setting my system to 1 or 2 cores, Ae is extremelly fast and responsive. Timeline scrubbing is super fast now even with keylight 1.2 and all it's settings. Adaptive resolution now works, Multiprocessing starts up
immediately and disk caching is working.
Conclusion
I am not able to set my system to use 8 or all cores in my bios, This causes so many performance issues in AE CS6 and CC and some in even CS 5.5. I need to use either 1 or 2 cores. As you might no this really sucks when I am limiting myself to only 4 threads when I could be using 32 threads. Pleas Adobe look into this issues with these systems that have 4, 6 or 8 core systems. This could possibley just be for Dual core systems too since that is what I have here.

Since a couple of weeks, processing Smart Sharpen has slowed down dramatically. A full frame EOS1Ds MII at about 4000x3000 px, 16 bit, takes more than 70 seconds when it used to take maybe 15-20! My computer runs Windows Professional SP2, has an AMD Athlon 64 2x, 4800+ on an Asus A8N SLI Premium mobo with 4 Gb ram. I have an identically equippped machine in another location and it is considerably faster. Any hints as to what might have happened or what I can do to find the problem? Btw, the efficiency is 100% according to the status bar.

Corel videostudio does not create proxy files.I bought pro x3 in february, but did not install it before yesterday. I installed the version linked in the purchase email from february 2011. I have not installed any updates or patches, so the version i use is Corel VideoStudio Pro 13.6.2.36
Settings:
- Corel is installed on c drive
- proxy folder is set to a folder on my d-drive
- Just to be sure to create proxy files, i've set: "Create proxy when video size is above 352 x 240"
- I have checked "auto generate proxy teamplate"
- i have checked settings-smart proxy manager-enable smart proxy
I have created a new project and added 2 files.
file1.AVI
video compression: MJPEG compressor
attributes: 24 bits, 1280 x 720
total frames: 340
file size: 41 738 KB
file2.AVI
video compression:Microsoft DTV-DVD Video Decoder
attributes: 24 bits, 1920 x 1080
total frames: 222
file size: 13 061 KB
I select both files, right click and choose "create smart proxy file"I open the "smart proxy queue manager" and i see the two files dissapear. However, they just fly through as nothing is really done with the files When the files are gone from "smart proxy queue manager" i open "smart proxy manager", and there's no files here. There is neither files in the proxy folder i've chosen.
I've also tried to play the video, hoping the files will be created automatically. I've tried to create the proxy files after installing the patch for pro x3.I've tried to reinstall videostudio.
I still can't get the proxy files, which means i can't edit the video either. When i preview with the editor, it stops all the time. The thing is, i managed to create the proxy files a year ago when i first tried the x3-version, and that's why i bought the product.how i can make it work?

Videostudio has left a lot of large proxy UPX-files. What happens if I delete these files to recover the disc space? Will VS create new ones if necessary?
Hopefully I can delete them, but if not can I move them to another disc?

I change my clips to proxy files and editing goes fine but if I am making a video that goes on over a period of time and I have to load the partly made video again the clips no longer show as proxy files. If I look in my proxy folder they are still there but do not seem to have been loaded into the edit. I am using XP.

When I found that X2 totally cannot handle my 720p clips, I upgraded to X3, and was happy to see that all my 1280x720p 60fps clips can be imported without a hint of complaints from X3.
However, as I started working with those clips, something does not work quite right.The main issue is that I could not get smooth slow motion out of those clips. 60fps clips when played at half speed should give you very smooth slow motion at 30fps. Instead, it stutters badly.
On further investigation of a straight render 60fps video output from VS with no changes made, I found where the problem was.VideoStudio coverted the 1280x720p 60fps clips to 30fps when importing the file. So every other frame from the 60fps clip is dropped, and previous frame duplicated.
Interestingly, it does NOT do this with 1080p 60fps file. You can get very smooth half speed playback at 30fps, even though you cannot create a 1080p 60fps output file.
Do I have to wait for X4 for proper 720p 60fps support?

I've been doing some MTS editing for my boss, and have been using the proxy file feature as my PC doesn't run the videos properly without using DXVA (would be a nice feature, by the way. my media players use DXVA just fine but VideoStudio won't let me use it's hardware acceleration.)
Anyway, when I finish up for a day and save my project, render the final files, and close out the program, my proxy files get deleted by the next time I load it up. I can use these still, as I often need to go back to change things in the edit, and remaking them every time is kind of a waste of time. Is there a setting somewhere I am missing, or does VideoStudio just always delete these files when it decides to? I'd like to keep them around and have them selectable and usable as long as I say, not how long as it says.

I prefer using the proxy workflow for fullhd editing because it allows fast timeline scrolling. My video rushes are all on external disks. Creating a project and proxies is no problem (takes some time). The problem however is, when I re-open VS with a project for which I created the proxies before, while the related external disk is not active (removed), I still get the tumbnails in the VS library, but I lose the proxies even after the external disk is being restarted. The strange thing is that the proxies (.upx files) are still in my proxy folder (local disk) when opened in Windows, but the VS proxy file manager doesn't see them anymore. Is this normal?

I use proxy files for my AVCHD editing. One of the options in the compression settings relates to " quality vs speed". Imo Proxy files are working files which content is not used for the final rendering. what the meaning / consequence is of the quality vs speed choice?

Loaded a MPEG-4 Media File 3Gb, went to setting, clicked on Smart Proxy cue manager, waited 40min and clicked ok. I check my Smart proxy file manger and it was there. My power went out, when I reload CV my files in Proxy manager were no longer there, and my file is back to being slow and jerky, that means I have redo this again.
does this mean I have to cue manger every time I wish to work with the same file?

I just today discovered how to generate proxy files from already existing clips that were loaded into my timeline.When VideoStudio ProX5 was done rendering all these timeline clips to the 'file manager' list as proxies, I closed the program and re-opened it.Everything was still in there but I did not notice any difference in resolution(it was still hi res) and the playback of the preview window was still very 'laggy'. Any way to allocate these newly created proxy files into my timeline as the workaround for smooth editing where I can later finalize/render the project down to hi res using the original source files?The project is very clip intensive with lots of overlays and effects.
As a note, I've made these proxy clips at a very low resolution so I would notice a big difference if they were being used instead of the current clips >all sliced (already in my timeline.)

Unfortunately, in my project which includes HD files, proxy files are not created automatically after capturing, even the "create proxy files" is checked. So to get the proxy files, I have to select all the clips in the timeline and right click to check "create proxy files". What I have to do in order to get automatically the proxy files.

On my current system and on my previous system smart sharpen runs PAINFULLY slow. It happened in CS3, CS5, and now with CC it often causes the Photoshop to stop responding and I have to force quit.
I currently have:
MacBook Pro Dual 2.5 GHz i7
8 GB 1333 DDR3 Ram
dual SSDs running Raid 0
OS 10.8.4
The rest of Photoshop seems to run OK, it's just Smart Sharpen that bogs down I'm usually working on 16 bit files that have gotten to be around 800MB-1.2GB by the time I get to sharpening.

If I have project properties set to anything but the default, I am unable to scrub through a clip when in clip mode if the clip has the second icon indicator, as shown in the screen grab below. This second icon (double diagonal frames) does not appear immediately. Before it appears, I can scrub in clip mode, but after it appears, I cannot. What that icon represents? My video files are from Canon HV20 (m2t 1440x1080) and my project properties match them.
I have a suspision that it has something to do with proxy files, and that once the proxy file is made, I lose clip scrubbing.
I just tried turning off smart proxy, and wouldn't you know it, I can scrub in clip mode.
I restarted X4 and clip scrubbing is fine. I enabled Smart Proxy, and clip scrubbing doesn't work again.

This evening I wanted to import a series of images from my card reader using LR (just updated to 5.2 from the 5.2RC); I have ~240 images to import. I always have LR set to convert to DNG on import, and also to save a backup of the original raw file (NEF) onto a separate HDD at the same time. LR has always been pretty fast to carry out this process: normally just a few minutes are required for that amount of images (not including rendering previews once the DNGs are imported). However, today it's suddenly become painfully slow - as I type this, it's so far managed to import a mere 58 images, having so far taken about an hour and twenty minutes! Each image is being added one at a time, with a long pause before the next one clocks up in the 'current import' folder. I've never seen such slow performance with LR before.
I wonder if this is a bug connected to the final release of 5.2? I doubt it, as I would have expected to have heard about this by now, but you never know...
I have recently - in the past few days - set up a number (at least 80) of new smart collections that pick up raw images taken at specific focal lengths, as well as another set picking up specific apertures used for each raw shot in the catalogue (unlike the majority of my pre-existing smart collections, these new collections are purely there for interest really - nice to see which focal lengths are the most used for example - but don't serve as an aid to any specific workflow). In short, I've greatly increased the number of smart collections running in my catalogue. Would having a significant number of smart collections slow down the image ingestion process? For example, is LR updating individual smart collections on the fly as images are imported, and thus having to pick through each collection in order to complete the import (I'd always assumed that this would all be added to a central index in the catalogue that the smart collections feed from, but perhaps there are multiple indexes, one for each smart collection)?
I guess the other possible cause could be a corrupt catalogue, although both the catalogue integrity check and optimisation complete without a hitch and everything else seems to be fine.
I'm on Win7 x64, running the LR catalogue and previews from an SSD (with images stored on a separate HDD), with an i7 3770K CPU, 16GB RAM, and an AMD 5850 Radeon graphics card.
