Thanks again.

That's VERY odd. Could you please paste the contents of that setmemorymax script?
It just tells avisynth how much memory it should try to stay within.

Ok, I think I know where the problem lies. Thanks for the report!

I feel I should really know the answer to this question already... :oops: Will I loose frame accuracy of my current scripts using an old version of the amvapp if I redo my d2v files with the new amvapp beta?

Not that it would really be too much of a problem to fix using Premiere's timeshift tool...

I honestly have no idea. I don't think it would happen, but it might.

I watched the video tutorials and I think they are pretty good and straight-forward. There was one little thing I think I saw though that new users might run into problems with. On a fresh Windows install, file extensions are hidden and for some systems the option to "Display the full path in the address bar" might be disabled. When users go to copy and paste the file path and name like you did in the avisynth video tutorial they might find these settings giving them a problem. Some sort of notice that the setting for these options are located in the Folder Option's View tab would be nice.

Pretty much everything covered in the tutorial can be followed along reasonably well in Vista. If the above information is included though, folder options for vista are not accessed via explorer's menus. Rather it is found by going to "Start -> Control Panel -> Appearance and Personalization -> Folder Options"

I think I made sure to leave the settings all at the windows defaults when I made the videos. It's probably just different in vista I guess (which I have never used).

hmm... I've always had to change these settings after a fresh install of XP. Granted, the option says "Hide extensions for known file types"

I guess the problem I had in the past was not the copy and paste thing I mentioned but rather the way I created my avisynth files; I would right click in the folder and select New -> Text Document and then change the txt to avs. Since txt was a known file type I ran into the extension issue.

Since dgindex files are not considered known file types in windows by default I guess my original point was moot.

Regarding the Bait and Switch method:
I have been told that it is impossible to use this method with Premiere Pro at this time - if anyone knows differently then let me know.


I do not have Premiere pro to test this with but shouldn't this method theoretically work if, instead of importing avisynth files directly into Premiere, you use MakeAVIs?

One last thing before I go to bed... I know you mentioned that you aren't using Vista but could you mention somewhere that the dgindex/avisynth tests at the end of the amvapp installer will fail to run properly and that even though they fail, the install likely worked? (I can post a screenshot of the error message that pops up several times during the tests if you think it would be useful.) This problem is encountered in the 32 and 64 bit versions of vista.

This is a problem I've encountered with the old amv app as well but all the applications after install so far have worked. I will try testing the updated apps in the new amvapp and get back to you if I have any OS-related issues.

Edit: I'm having some problems already, at least on my 64 bit install. I'll post more later after I test more including on my Vista 32 bit and xp pro installs.

Maybe include a short explanation for why Levels should be used for adjusting brightness and contrast? The AVIsynth guide for Levels suggests to adjust them using Tweak.

http://avisynth.org/index.php?page=Levels wrote:For adjusting brightness or contrast it is better to use Tweak or ColorYUV, because Levels also changes the chroma of the clip.


I assume when the avisynth manual says that, they mean it in the literal sense of actually changing brightness and contrast. Brightness and contrast adjustments mean very specific things, and are usually NOT what you intend to adjust on your video. Brightness and Contrast are terms that everyone is very familiar with, but few people really understand them.

Let's take Brightness for example. Adjusting the brightness is basically the equivalent of taking a solid white or solid black image and overlaying it on top of your video. It doesn't really make your video "brighter" or "darker" according to what most people's perception's are--it merely makes it "more white" or "more black". A basic "contrast" control has similar problems. By using Levels, we can make the image look more visually darker or lighter, not simply whiter or blacker.

Here are a few links with some more information about levels, hope this helps.
http://www.cambridgeincolour.com/tutorials/levels.htm
http://www.biorust.com/tutorials/detail/198/en/

Whoever decided that a television's black-level controls should be called "brightness" and white-level control should be called "contrast" should be raked over hot coals.

http://www.poynton.com/notes/brightness_and_contrast/

The resultant confusion and eventual spill-over entrenchment into other display categories makes correcting this error impossible now.

Corran: regarding bait-and-switch, the issue there was that Premiere 6.x had a feature where you could go in and replace the clips with other clips, but premiere pro took this feature away. I think you could probably do it in premiere pro though by simply moving all your files, then it should ask you to find them... at which point you can point it to your new files. I guess :\ I'd definately make project backups before trying anything like that though.

Regarding vista, sounds like it has quite a few issues. I'll see if I can do some testing on a vista system myself, but I'd still like reports on anything and everything you find that has problems though, so I don't miss anything.

That is what I currently do in 6.x. It will ask for the location of the avis and I'd point it at the avs scripts. If they are all in the same folder it would then detect the rest automatically.

An alternative to the bait and switch method that I use and couldn't find any mention of is to make two versions of my avisynth scripts and place them in three folders as follows:

AVS Scripts
|
+--High Quality Scripts
+--Low Quality Scripts
+--Copies Premiere Sees

As long as the high and low quality versions have the same filenames, frame rate, and resolution, premiere has no problem switching between them. (Don't swap the files out while the project is open, obviously.)

Regarding vista, sounds like it has quite a few issues. I'll see if I can do some testing on a vista system myself, but I'd still like reports on anything and everything you find that has problems though, so I don't miss anything.


Will do.

alright, followed the guide and it works.

I took an entire episode which I had a script for already encoded it w/picvideo mjpeg.
made a project with proper settings
imported the low-quality avi
saved and made a duplicate of the project.
moved the avi and opened premiere, re-linked

after that worked I exported a section of the timeline (using the .avs)

I then re-linked the low-quality avi and cut it into random size chunks and randomly placed them on the timeline.
unlinked then re-linked the avs again
all my clips remained the same.
exported and did a quick comparison to make sure.

to un-link/re-link in premiere pro you right click the video file in the bin
about halfway through your options you see "link media" and "unlink media"
one of the two should be greyed out

when you click unlink media, an option window pops up asking if the media should remain on the disk or be deleted, I chose that the media remained on the disk.
then the clip(s) that were made with that file go to "media offline"

right click the same video file in the bin and choose link media, and link it to the avs script.
video comes back

I didn't test it with the premiere plugin in the amvapp beta (didn't get the amvapp beta, in the middle of a project)

I'm using this plugin for premiere pro
cpu: Athlon 64 3200 (2.0ghz, up to SSE2 instruction set)

footage was IVTC-ed using TFM and TDecimate (720x480, PAR 0.9, 24.00fps)
I did not change the colorspace to rgb24 or rgb32 (left it in yv12)

Hello,
I found some point, where maybe something is wrong or some information can be added.

Colorspace:
"DV - This uses 4:1:1 YUV which has the same number of chroma samples as MPEG2 but in a different order."
Please add: DV (PAL) is 4:2:0

Telecine:
PAL-Telecine = PAL-Speedup
3:2 Pulldown = 2:3 Pulldown
See image, website (sorry only german) and doom9

pan&scan
I think it would be good to write a little more about pan&scan like:
„What is being done in a pan&scan transfer is that a part from the source frame, having an aspect ratio of 1:1.33 or 4:3 is being cut out. This is symbolized by the red square in the picture. This "window" is not fixed but flexible. So when the actor moves to the right border the window can follow him up to a certain extent. This is the pan part of pan&scan. In certain cases the window might also zoom in on the frame, hence the scan part. „
See doom9

Maybe nice info for ripping:
Which PGC is played ?
„By selecting the right PGC you can get the right version of the movie. Also.. the PGC corresponds to the Title number being displayed in your player. Here's just an example (Matrix - follow the white rabbit feature = Title 6 or in other words PGC 5 since the PC starts counting at 0 internally). „
See doom9

Best regards,
Ti
