Compressabilty Check

[Jbrohms]

I'm trying to setup multiple jobs to encode but after you start one you the now button on the compressabilty check is grayed out. Can I setup mutiple jobs and run the compressabilty check on all of them

[MaTTeR]

I'm not sure this is possible as I tried the same thing a few weeks back and it didn't work. It would certainly be a cool feature though.

i'm not sure either, but isn't the idea of doing the compression check to SEE how the movie compresses? if you're going to go to bed or to work or something and want GKnot to encode a bunch of different jobs, then who is going to check the compressibility test after it's finished and before the actual job starts?

...or do you want to do all of your compression tests first while you are away from your system (which would require cueing them up in GKnot) and then setting up the group of full encodes after you've checked the compressibility tests.

...come to think of it, that's not a bad idea! :) you could do multiple compressibility tests, say with soft, neutral, and sharp bicubic filters, and then pick the best one.

I found another guide on gknot.

www.doom9.org goto guides pick divx3 goto gknot and this is the one I have been using but then I went to

www.doom9.org/gknot.htm

And it's a little different when it comes to the compressabilty check

after you have check use for compressabilty you just save the stat file and open another nandub and press F8 the will run the compressabilty check. then finish your settings save and encode and just don't say yes to it right away. I havn't tried this yet but I think it will work.

How come there is two different guides? Which one is the better way?

I understand what you're saying.

It's more a question of naming the files with the different compressibility checks.

This way we could open the d2v and load the different compressibility checks.

For me: IT would be AN USEFUL FEATURE

if we could set up a few compressibilty tests with different settings and name them accordingly.

It's a pain (well not that much.. but... anyway it wouldn't harm anybody) to have to repeat for the same movie several comp. tests but it's something that many of us have to do for the best results.

I would say in average I'm doing 3 comp. tests per movie.

All the best,

<Name>_<Resolution>_<Bitrate>_<Filter>.avs ??

I'm not in front of GkNot (Work...WOrkkkkk...dam'nd work) but if we choose instead of "Now" the save, and we did this procedure for different settings... can't we queue them all at the same time???

All the best,

I've just thought of something myself and thought I'd come drop a thought in here and see what the verdict is but he goes. I thought to rip the movies you want and then then compression check them all and then load one video and then while the first video is encoding load your second .d2v file and then load the compression check that you did before cuz the compression check is saved is it not for each one you do. And that way you can queue that movie without having to worry about compression checking it as it were done before??

just a thought, tell me what you guys think cuz I wouldn't mind doing it if it works. as you can tell I haven't tried it yet but I will and if I do it before I get a response i will let you know how it went.

[Dionysus]

also have a question for those who read this post. AFter I've done the compression check is the video file size predictable cuz I was doing enemy at the gates and it is telling me that it will be way under a two cd rip yet it still had two hours left of encoding, and then i accidentally aborted it, but it was already at 1,000,000 approx. and there's no way with 2 hrs left of encoding it that ti wouldn't go over by lots. And how good is a one cd rip, cuz with a two/three cd rip you have to have sucha huge resolution after compression to stay around 65-75% but with a one cd rip the resolution is reasonable but I'm too impatient to have to do a rip twice just to see.

Anyways, I'm almost done my test of the enqueuing two compression checks. Almost positive that it iwll work.

with gknot it's not possible to start multiple instances of vdub/nandub. that's why it's not possible to run a comp-check while encoding.
but i could put a "queue"-button next to the "now"-button...?

of course you would have to "load" the result manually later on.

wef.

@TheWEF

The queue idea would work great. I would like to run several compression checks on different movies, come back later and load the stats for each and start my encoding journey. Thanks man!

[Dionysus]

how come my suggestion wouldn't work. Just do teh compression check, and then load the compression check before you encode your movie. check this:

1. compression check all movies before hand

2. load .d2v file

3. load compression check file

4. encode movie

and then go back and start at one and it will encode it as if you were just finished the compression check will it not??

YES YES YES!! great idea..

MaTTeR, i agree. that's exactly what i'd like to do too!

[Sharro]

A QUEUE BUTTON next to the NOW button?? GREATTTTTT!!!!!!

The WEf and about naming them?

:-))))

Thanks God for all the Wef's of the world ...

Take care

That would work fine, mof that's what I do when I am leaving for the weekend and would like to encode 4-5 movies.

Just do the comp-checks on all the movies first, get your settings right, then load the jobs into the queue.

Unfortuneatly you cannot do a comp-check automatically, but do you really need to? As I use it, the comp-check is used to select the correct resolution with regards to the compressiblity of your movie. Even if this was an automatic option, you would still have to be there to select resolutions, unless you trust Gknot to do it for you. I know I don't (no offense Wef).

Better to do the compressibility checks first before you start loading up your job queue. You'll get better results.

One nice feature would be to have a seperate queue just for compressibility checks, that way you could do multiple ones while you did something else. Then just load each result manually, set your job queue, and be done.

If this has already been suggested, pardon me...
