Corel Video Studio x7 slow rendering

[lata]

Hi coupernst

Did you try activating Smart Proxy,??
Then right click all files in the timeline and choose create Smart Proxy, may take a while.


You are using Gopro.mp4 video files. A highly compressed hd video file.
Video Studio may have difficulty in reading those types of files, hence the slow juttery playback.


I don’t use GoPro but there are forum members that do, can you ask a new question regarding editing GoPro mpg4 files, maybe those responses will address your playback issues.

I have used AMD 8320(8 real cores) with % cpu when rendering often ramdom from (30-50%). When I changed to Xeon X5650 (6 cores - 12 threads) almost time my cpu only use 22-40% ,its very slow.
However,the benefit when I change from desktop to workstatition is that my computer haven not auto restart ,blue screen and crash...
ps: corel need to optimize our system for general purpose (speed)

Looks like your HDD is the bottleneck...

Hi...hard disk as bottle neck is nonsense.

When you render 50mbps sources to a 40mbps movie and the rendering time takes longer than the playtime of the movie...the harddisk gets booooooored...even the slowest one...my harddisks have a load smaller 10% while rendering (and doing other stuff in the background)...., CPU is jumping between 20-70. GPU has 0%....so: VideoStudio really sucks...it is a waste of money and I regret I spend my money for that...was the first and the last time.

Sure Proxy-Settings help while using the program, but it doesnt makes sense that video stutters with a PC like mine. (FX8350@ stock or mostly @ 8x4,3Ghz with 8gb DDR3@1866 and 280x GPU)

I use
- 1080p50 28mbit files from gopro hero 3+ BE
- 1080p50 50mbit files from Panasonic HC-V757
in the same project which is set to 1080p50 with 40mbit (100% quality, 2-pass,...)

Sometimes I render the actual video/project status for my dropbox/friends to the mobile 1080p25 5mbit profile...even that takes nearly twice the playtime to render (example: Playtime 25minutes, startet 20:20, now 20:46 and 64% rendered)

wondering why noone has a problem with that..

Hi coupernst

I have a modest pc which does its best to render, depending on what it has to convert obviously changes the render times.
At best I do it in real time, generally with a modest amount of edits.
With no edits a one minute clip takes approx. 25 seconds.

I set my project properties to match the video files properties, then Share Same as First Clip
I normally work using 25 fps but have on occasions used 50P, properties below,

I just ran a quick render test on a short 40 second clip, render took 26 seconds.
Using 25 fps a 60 sec clip took 28 sec.
I then converted the 50P to 25 fps that gave it something to do my CPU running at 90%,(all 4 cores) render took 124 seconds, and if I reduce the data rate the times reduced to 85 sec, to be expected as the file size will reduce so less data to move.

MPEG Transport-Stream Files
24 bits, 1920 x 1080, 50 fps
Frame-based
(HDMV-PAL), 16:9
H.264 Video
Video data rate: Variable (Max. 26000 kbps)
Audio data rate: 384 kbps
Dolby Digital Audio, 48 KHz, 3/2(L,C,R,SL,SR)

coupernst do you match your project properties to your video files being rendered. Use the Show Messages option set via F6 should match your properties, start a new project then add one of your video files, if the properties are already correct then the message will not show. Check your project properties.

Now Share Same as First Clip, how long does that take.

100% quality and two pass rendering is gonna be the slowest as you are telling the encoder to take its time and be accurate, whether you notice a difference in quality between 100% and 80% is in the eye…

If you are not bothered about file sizes to fit to disc then use Constant bit rate rather than Variable that should improve render times, file sizes may be larger?

I record 1080p50 files and I render them to 1080p50. Since I use many effects and overlays in my movies "smart rendering" isnt used that much anyway. Since I use two different cams with different codec settings "smart rendering" is even less possibel, so it makes no sense to use that function (which is unstable anyway).
Whatever I am encoding: same codec, other codec, same fps or half fps....that all doesnt matter...my CPU can calculate 125 millions instructions in a second...and not even 20% of this possibility gets used when I render a movie with VSX. I dont mind large files, drive space is cheap and every less compressed pixel is worth it when you watch it on a large screen / Beamer / whatever.

The fastest CPU on the planet is not worth it, when the software is not able to use the power...another example...a boy (VSX) doesnt need to drive a formular 1 car (highend CPU...or my not high end but quiet fast CPU when all cores are in use)....Just dont bother about codecs and fps, resolutions, whatever...you can render everything to anything, results may be bad, but the CPU always has to get loaded by 100%

I am not complaining that it takes longer to render a movie when I choose a higher quality of the result...I complain that which setting I ever use, my cpu load is way to low, so the hardware is used not effectively by the software.

Again:
When I use free tools to compress a bluray to a lower bitrate (also 2 pass)...I get 100% load (even a very high GPU load), when I am unzipping files...I get a high load...when I am running superpi for benchmark...I get 100% load....when I use VSX...I can even play fu...ing battlefield in the same time without having a loss of game performance (thats just irony...but I hope you get the point).

I realy like the handling of the program (VSX), but I dont understand why this dumb program is let my being waiting for my movie instead of pushing my CPU to the limit.

wow...new move...VSX crashes when I edit Bandicam AVI Records...f..ing programm. First and Last time I spend money in that sh...t

Hi

It may be Bandicam’s encoders that is causing the problems, there are approx. 800 different types of AVI, most being tweaked by the software.
You don’t say what codec is being used?

Bandicam as far as I know can record raw AVI, uncompressed avi, at 63 Gb per hour is quite large.
Not sure if Bandicam gives other recording formats, maybe MP4

You may be best to choose AVI. Mjpeg as the compression to use during capture, I think Video Studio may cope better with that format.

The recorded frame resolution may also cause problems, try setting a standard size 1280 x 720 or 1920 x 1080.
you don't give any details regarding the videos properties?

So don’t be to upset with Video Studio, tomorrow a new phone will be launched, super video HD recordings, great for internet playback, but rubbish when trying to edit.
And if you wished to edit the phones manufacturer will advise to convert to a more editable format.

not all files have problems. The large files (3-10tb) make problem

[canuck]

"3-10tb" files? That must be an error!

Hi

Yes I had problems with that video, seemed to play very slow, crashed program whilst rendering. Not sure that VS liked the Avi - MP2 Audio combination.
VS does not do mp2audio renders since VS 12 (X2)

Did you try recordings using Mjpeg + pcm audio as recommended earlier.

[coupernst]

* 3-10tb files a problem...why, ram isnt used more then 50%
* I can play the full project inside VSX without a problem, when I render the project, then it crashes
* when I start the problem-maker-file in the project as a "clip" (double click it on the timeline, so VSD switches from project editing to clip editing, then press play)....then VSX crashes too...funny thing...
* audio might be a problem of bandicam files. new records with pcm audio got rendered without any problem. Testing now the problem project with all audios muted...rendering is running in that moment

[coupernst]

looks like that mp2 audio is the problem with bandicam, thanks for that tip, but also pcm audio bugs while rendering....it gets unsynch, at least while live recording inside the game. I will test Replay records....

[coupernst]

no, vsx gets unsynch between audio and video when I render bandicam movies to another codec.
