What's the advantage of frameserving?

[videocheez]

I've been reading that frame serving an avi virtual dub to TMPGE is an efficient way to encode the avi to dvd. Why go through the extra effort? Why not just load my avi and wav into TMPGE? Is there some reason such as reduced quality loss or more speed? Any help would be appreciated.

thanks in advance,

Frameserving is a more flexible way to feed video sources (of possible different formats) to the encoding application.
Most frameservers (AviSynth or VDub) have a lot of functions/filters, which acn enhence the output.And you can make an edit script, which only presents chunks of the input (for example cut/replace bad frames), which need temporarly files without frameserving.
IMHO frameserving is an elegant, flexible way (and only slightly slower) to render videos.

Can I use vdub filters in addition to TMPGE filters. Also is there a guide that tells how to implement vdub filters? I couldn't figure it out by clicking around.

Thanks in advance,

You can use VDub filters during frameserving any time you like.But speedwise, I'd recommend using AviSynth: it's much faster and the filters are nearly the same. And you can use VDub filters additionally.
There is a tutorial within the VDub FilterSDK (if you want to implement you own filter).The same goes for AviSynthSDK.

To be honest unless you are going to use some exotic filters that aren't included in TMPG, I wouldn't recommend getting into the whole frameserving thing at all. TMPG will accept most files "as is" without the need to frameserve from other applications, and it is the quickest way to get things encoded ... CCE on the other hand is virtually useless without a frameserved file - one of the reasons why I wouldn't touch it with a barge pole!

How do you edit an avi then, when not with frameserving?
I don't know any way to join or cut avis with tmpgenc before encoding!
Or are you suggesting temp avis (made with a NLE)?

To fully answer the question - the advantage is that it stops unecessary intermediary saving of the file and most importantly the inherent losses in quality by compressing it , decompressing and finally recompressing it in TMPGenc , and it saves time as well .

BUT if you have the hard drive space you can just save it in a lossless codec (HuffyUv or uncompressed video) without the loss in quality , BUT this increases total filtering/encoding time .

If you join/edit with Vdub you can save using Direct Stream Stream Copy, no re-compression, no loss. It does take more diskspace however.

TMPGEnc has basic editting functions within the Source Range window as well.

TMPGEnc's filters are extremely slow and increase encode time by huge amounts.

If I have big files to edit or if I'm using Vdub filters (Logoaway, 2-d spatial etc.) then I frameserve.

If you want to capture a 60 gig AVI file on a FAT32 system, and want to feed the file to a mpeg encoder, frame serving is the only easy way to do it. I could not live without frame serving on a Windows 9x system.

Frameserving helps alot on downloaded files since they tend to have bad frames from transfering them--thos bad frames can mess TMPGEnc up and cause ausio synch problems and other things. Using Vdub filters would make it faster to encode then using TMPGEnc filters.

I highly recommend frame serving I used to just load the avi and click encode but too many corrupt things here and there forced me to look into it plus I like to edit films for example if I want the 58 to the 60 and another part 101 min to 112 and I want them together I write a script in avisynth to say so

another exampl if you capturer broadcasts and you get ads/commercials you can get rid of the adds with out having to resave etc....saving time

The best way to frameserve is with avisynth I have only being doing it for about 3 weeks now but I would never go back plus it's alot of fun writing a really long script and the test it out in vdub to see if what you wanna do works then load it up into your encoder then encoding it....that's the joy....
Frameserving is fanastic if you know how to do it....Sure you can load an avi up and use internal tmpgenc but there's no fun in that....

Framesering is fun.....I gotta get out more......... I used to be a rave dj now I am a computer nerd

Does anyone know under which conditions tmgenc doesn't like avisynth scripts?I have one script, which plays perfectly under VDub and WMP, but tmpgenc doesn't like at all.Other avs file can be opened by tmgenc.Any idea?

[2573]

Can it use frameserve from vdub in procoder?

Is there any way?

I found the erroromehow the registry entry for avisynth.dll was changed in such way, that it pointed to the wrong path.After correcting that, everything's fine now.

Lots of people frameserve when its not needed.

It takes extra time.

Some people need it, some don't.

I just transfer VHS to DVD mostly. Nothing needed here other than MPEG2 capture and a dump to disc.

Only when I restore video do I get fancy and frameserve and call up filters galore.

Are you sure you need this? What is your source, and what is your desired result? And what kind of hardware do you have to work with? Those are the really important questions.

[energy80s]

My point exactly, unless you are getting into a lot of filtering or editing, just load the file directly into TMPG and let it do its magic!
