what are the benefits of frameserving

[magnus]

I'm still a little confused on the frameserving issue. I know it will allow tmpenc & vdub use different formats but what other benefits does it offer?

Hi,

The largest benefit to me was that it allowed me to feed segmented avi files into a mpeg encoder, since win98SE has the 2G limit on avi files. If one uses avisynth tho, the frameserving from vdub is not needed.

Hope this answers your question.

Avisynth->CCE...speed speed speed. Not mention the quality gains as well.

[Randy64]

Exactly.. Kdiddy. That's the way to go..

So when should you frameserve and when shouldn't you. What are the reasons for the quality gains you speak of. Sorry in advance for the ignorant questions, just trying to understand all this.

I find frameserving is the best way to pass video from application to application without having to save a huge uncompressed/huffyuv file onto your hard drive.

hmmm good one, well seeing as how I always frameserve, I can not think of a situation where you wouldnt. I think it was born out the very needs that Dave B spoke about.

What are the reasons for the quality gains you speak of.

Well, for starters, Frameserve allows you to add more filters that most encoding applications do not come with that in some cases can improve or help maintain quality. Alot of speed comes from resizing the video BEFORE the encoding application gets it, therefore it does not have to waste time resizing (in most cases with a poor resizer at that).

No need, it is the Newbie Forum, this is the main purpose of this forum.

Let me throw out a couple of examples so I may understand a little more. Say I download a file from sharereactor already in mpeg format. Tmpenc accepts it but vdub doesn't should I fserve before burning.

Example2: I download an avi & want to encode it to burn. Vdub & tmpenc recognize it. Should I fserve it to edit or encode before burning?

Thanks for all the help guys. This is all new to me and I'm the type of person who doesn't like to do something until I feel it's the best possible.

Let me try and explain the logic behind when to frameserve in a couple of examples.

Lets say you have a capture file (MJPEG/HuffyUV/Whatever) and before you send it off to TMPGEnc you want to apply one of VirtualDubs wonderful spatial filters - or you want to put a logo on the screen.

One way of doing this would be to load the video in VirtualDub apply the filters and (because we don't want to lose any detail or quality at this step) we save the video as Uncompressed or HuffyUV avi. We then load the Video we just saved into TMPGEnc and convert to MPG.

The method above is absolutely fine if you have acres of harddrive space to save two copies of your video. Frameserving eliminates this requirement by allowing two applications to talk to each other. In the example above VirtualDub can pass the video stream directly to TMPGEnc without having to save it uncompressed first - provided its frameserver software is up and running.

Now, for the second example lets say you have a DVD Rip and you want to convert it to a VCD thru TMPGEnc. You are perfectly happy to let TMPGEnc do the resize and apply filters (if necessary) on the video. There is no need to frameserve in this example as you do not need to involve another application in the process apart from TMPGEnc.

There you go.. clear as mud
