Is Rendering/Saving suppose to take THIS long?

Post by ConfusedUser »

Hello all,

First time user to VS10 and new to all of this A/V editing stuff. I have a 21GB DVR-MS file recorded in HD, which VS had to pre-process into a MPEG file. I edited the clip using Multi-Trim Video. When I go to Share -> Create Video, my first test was to save it as a NTSC DVD 16:9. I knew it was going to take a while so I left it on all night. 10 hours later, it was only at 19%. The preview images of the background showed verrrrryyyy slow rendering, like literally milliseconds being done every few seconds. Is this normal because I don't have a video editing rig (P4 2.8, 2GB memory) or is there something else going on?

Thanks!

Depends if you did any editing and made changes to the video/audio properties of the original video file.
Being the fact your using VS for the first time you may have some settings that could be wrong for smart-rendering the video.

MF6_Plus is also nice program for working with HighDef. Providing you do not edit the video and only multi-trim it MF6+ has a fast_export feature. It does all the thinking for you and smartrenders the video using the source videos properties. It's very fast.
Before attempting such a long render/conversion I first run a test by trimming the video down to 1 minute. Then render that 1 minute video and take note of how long it takes. Then multiply that times the length of your real project.

Using MF6+ I rendered a HD 3Gig file to other HD video & audio properties. This took about 1hr 10min on a 2.8HT P4.

You are making a big conversion because your changing every parameter related to the source video/audio except the frame rate (I hope :) )
I believe this may be normal to take so much time because you are changing major formats.

The length of your video after you edited it is important. You didn't post how long the video is.

etech, thanks for replying. The video is over 3 hours long. I read another post about converting times and it confirmed my fears. I didn't realize it would take a leap year to produce a trimmed video. I found I can convert the 21GB MPEG into the DVD-DL first. So you're saying MF6 is a fast way for trimmed conversion?

Right now MF6+ works with the HD-mpeg2 files very well.
If you convert HD-Mpeg2 to SD-Mpeg2 Dvd Compliant this takes time because you are changing the framesize of the video.

In MF6 it's very fast to multi-trim or trim any file SD or HD and then fast export the file to a new video file keeping the exported file in the same format as the source video.

In MF6 this is the "Fast Export" Feature and it's using "Smart Render" to do this.

A 3 hour HD to SD conversion on a 2.8 machine does take a long time.
I haven't used VS or MF to convert HD to SD. I'll use the down convert in my cam and use dv.avi format for SD video.
I have converted HD to SD in mpeg format using other software. A 20 Minute video takes about 6 or more hours to convert on a 2.8Ghz machine.
I don't consider mpeg conversions to always be reliable and it depends on what program your using to perform the conversion.
Converting HD to SD via software is very time consuming. It's much easier for me to use the down_convert feature on the HC3 cam and capture dv.avi, then convert that to DVD mpeg or record directly into a dvd recorder.

According to MF6+ calculation on a 2.8 Non-HT Laptop 500fsb to convert HD to SD is approx 2 to 2.5 times the length of the video.
Maybe you should try MF6+ trial.

Ok, I used WinAVI to convert the HD DVR file to DVD format. Using VS10, it was formatted/converted into MPEG format for editing. After multi-trimming the video and letting it run for 10+ hours, the rendered video comes out! Problem is that the audio is totally screwed up. It is stuttering and repeating a section of the video like 5 minutes at a time. Is this a common problem with VS10? The source file had no such issues.

Thanks again

sjj, I meet the minimum specs and the video was rendered. My question is now pertaining to why the rendered video is displaying stuttering/repeating audio?

you need a dedicated rig to do video, no games no work and other junk !!!

I have P4 3 Ghz Northwood and using top of the line software Mpeg2 encoder, i reencode a DVD-9 to a DVD-5 in 6-10 hrs, when similar riggs can do in 90-180 min. i have games and work and Anti-virus running in the background is the reason.

An then u are working in HD as well

I disagree. I have everything but the kitchen sink on mine and I have no problems, renders are 1-1.5 times the length of my project. As you can see from my system button I do not have a workhorse machine by today's standards. But I do follow the suggested workflow and I only work with dv-avi (no divx, wmv, mjpeg, etc). Granted, I haven't yet made the leap to HD.

So there is no consensus on what could be causing the audio abnormalities?
