Full Version: Necessary!?1 hour videos takes 20 hours to render.

I had this experience to output roughly 30mins which takes around 7 to 8 hours to the MPEG2 format which is 720x480.

Now this 1 hours video takes 20 hours to complete render. and I only applied the basic crossover transition effects.

Is there any FASTER way & Maintain the video quality method for Sony Vegas?

Normally, I set to "Best" quality & Two-pass. I found dat setting Two-pass, the rendering hours is almost the same when without Two-pass checked. So, i prefer the Two-pass.

I got too many videos to render. I couldn't just let my PC runs a whole week to render the videos days by days.

Please shares you best rendering setup without dropping the original video quality from the DVCAM and make into DVD.


thx alot. flex.gif

What is your source,i mean your original file . Best is to stick to your original source size. This will reduce time too. The format 720x480 is D1 (DVD) NTSC.

With a slow P.C. (Pentium 3) i had once spent 13-15 hours converting a RAW VHS capture (720x576 - PAL) to VCD with HIGH quality setting with rendering softwares. So yes if quality is want you want then it can take many hours depnding on your P.C. speed and settings.

If your end MPEG file is to be DVD NTSC, then its best to capture in NTSC but i beleive most likely you may have a PAL type capture 720x576 (PAL). Also the DVD audio file should be in 48khz.

To overcome all that hours on convertions and not too mention high eletricity bills, i got my self a good hardware encoder long ago. I just feed (play) the video on the camcorder and capture the end file into an DVD Mpeg file with a 9Mbs setting. If you have a ready DVD mpeg file even with adding transitions and effects the rendering time is very short. Not sure if Sony Vegas can edit Mpeg files but all new softwares must be able to do it nowdays.

why not process everything first in raw video format (the one that you log and capture from the DVCAM).

after u've done with the editing, only then you convert it to a compressed video format.

i am using AMD 64 3000+, 1.43GB RAM. Forgot to mention i am rendering the original files from the portable 3.5" HDD. And the saving destination is the PC HDD.

My original source file is also 720x480. Dat's the reason i choose NTSC format at the first place.

Soulfly,

I am straightly using the Raw format from the HDD camcorder which is MOD format. I checked it as 720x480 format. Maybe MOD is AVI ?!

Yeah, i should really try to convert into UNcompressed format such as AVI first and see how much times i can reduce. Seems like the 20 hours is taking double processing steps (RAW->AVI->Mpeg2).

My video is 50% now and 12 hours to go... wonder should i just cut it off and render into AVI. Then AVI to Mpeg2. Hopefully, it won't takes like 20 hours to make RAW to MPEG2.

thx to both of the replies.

amd 3k+ is quite an average computer and shouldnt take so long ler...i am using the same proc as you with half your RAM...running smoothly..

How smooth? Can yours 1 hour videos rendering out within 1 hours to 2 hours something?

I just asked my brother his JVC HDD cam gave a program inside CD which allow 1 hours video being rendering out with around 1 hour too. Plus the text & transition effects somemore. Output format is 720x576 , PCM Wave.

Next week, i can have the copy.

My works inside vegas is working very smooth & stable than ever before i was "addict" in Pinnacle Studio.

The bothering issue is Output Rendering hours as i stated. Nothing wrong wif the Vegas or my OS.

What's the file format after you capture from your HDD cam ?

I have an impression that the file format store on the HDD cam is already in MPG 2 format. Why do you still need to render it ? adding cross over transition ?

Perhaps try to put a few clips of your source on your PC HDD then do a try see if that will improve.
