Aviutl Tips, Tricks and Support thread

[poisondeathray]

I'm trying to load a 720p 60fps 1.5GB file into the editor and it's not responding? Ok, I waited and it finally loaded, nice!

It creates an index file with L-smash upon importing (if L-smash is set to the highest priority in the settings), so it might take a few seconds (Longer for larger files)

Once index is created, you don't have to do it again for that file (but new files will still need to be indexed)

[tyee]

Ok, I'm hanging in there. I know this program has lots of potential to make things easy. Regarding my mini problems, I had to change the max number of frames in the ini file, then of course it stays put. When the project window comes up, I should just let it take the settings from the file it just read instead of manually entering the info. I thought the greyed out settings were what it was reading from the file, but no, it's just a default value (640x480). I just loaded a .mts file (camcorder) into Aviutl via a .avs file (dss2) and of course it's lightning fast, now that's what it should be like! But I get no audio. Do you remember how to get audio when dss2 is used, dss2(file.mts)??

dss2 has no audio, it's video only

You have to use AudioDub(), with another source filter for audio. I'm going to assume you want a non indexing source filter

vid=dss2("file.mts")
aud=directshowsource("file.mts", video=false)
audiodub(vid,aud)

The problem with dss2, is it's a directshow filter (predisposes you to various directshow issues), and you will always miss the last frame (last frame bug)

[tyee]

Thanks poisondeathray, I googled last night and found the same answer on doom9. Do you think I will have sync issues with the audio? Maybe I should use ffvideosource and ffaudiosource?

Another question - when I do my backups I use avisynth MT to increase the speed which works great, can I use the MT commands in my avs script here for editing or is it not designed for scrubbing a timeline?

It shouldn't be out of sync but you should test it

It depends on which filters are being used, but I wouldn't use MT for editing in general. MT predisposes you to frames getting mixed up, out of order , especially when you scrub around . Even with FFMS2, I would set threads=1. For extra safety you can even set seekmode=0 (very slow). For AVCHD, L-Smash tends to work better than FFMS2 as a source filter. The avisynth version of L-Smash requires indexing as well

I'm having more problems. Today when loading my .avs file with dss2, I have 4 instances of LAV video decoder in my task bar, 4 instances of haali splitter, 2 instances of ffdshow audio decoder. I try to open any of the export windows and nothing happens. Looks like most items under "File" menu does nothing. I just installed dotNet 4.5, and the three C++ redist.'s as required. Still the same thing. Any tips?
Here is my avs file -

v=dss2("file.mts")
a=DirectShowSource("file.mts")
Audiodub(v,a)

I try to add a filter and I get tons of error windows coming up after I click ok. Insufficient memory window is one of them. Commit memory seems to be around 1.6GB. I read that somewhere earlier in this thread so I will try to find it.


Update - I enabled Large Address Aware and it seems ok now, but should I really have all those instances of LAV, Haali, etc.?

I tried loading the .mts file directly into the app and let it index and now memory usage about 600MB instead of 1.6GB!

Ok, I'm hanging in there. I know this program has lots of potential to make things easy. Regarding my mini problems, I had to change the max number of frames in the ini file, then of course it stays put.

To what number did you changed?
I can change the value to 640000 or 1280000 in
File> Settings> System Settings. (requires restarting AviUtl)

But if your AviUtl folder is read-only or inside C:\program Files\, there may be a problem.

1. You do not really need DSS2 or avisynth. There is already a DirectShow File Reader included.
Go to File> Settings> Import Plugin Priority and move the "DirectShow File Reader" above "L-Smash Works".

2. You can skip the indexing by L-Smash Works by:
File> Settings> Import Plugins> L-Smash Works File Reader...> Uncheck "Create Index File".

3. Do not mess with the INI or make any hack until you get familiar with this program.

These aren't aviutl issues - these are directshow issues. It's "normal" and one of the many problems with using directshow

[tyee]

Ok, looks like everything is ok after I did the above. I will not use avisynth for now. I changed max frames to 600000. Seems ok. L smash works seems ok for now with the camera mts file. It was having problems with an mp4 file I created from the mts file. I will try again and see if it doesn't like it. When Lsmashworks was starting to index the mp4 file it would not show the indexing window although it was doing it in the background. It seems fine with the mts file though.
If I skip Lsmash indexing will it still be frame accurate?

Update - It still doesn't like my mp4 file created by ffmpeg from the mts file. I just tried another mp4 file, a few of them from youtube and they all play fine except the audio breaks up randomly every couple of seconds. These mp4's don't seem to be indexed. The project window comes up very fast, even for a 4GB mp4 file.

1. Skipping the idexing step should not affect frame-accuracy, but seeking will be a lot slower.
2. Your mp4, or probably the source mts, may already contains error.
(PS: L-Smash Works is based on FFmpeg. So if FFmpeg screwed your MTS, there is a high chance that LSW will also fail to handle your MTS correctly. In that case, try DirectShow Reader.)

3. Youtube's mp4 are by default streamed using "DASH format", not the standard H264. You may try using ChrisPC Free VideoTube Downloader to DL the video AND CONVERT it to standard H264 MP4 first.

4. Be Aware that AviUtl is primarily an EDITOR not TRANSCODER, so before you feed the file into AviUtl, it's better to check if the file plays normally using MPC-HC or Windows Media Player.

Do you know why my mp4 audio is breaking up when indexed with Lsmashworks? I even tried some apple mp4 trailers and it still breaks up.

Update - I disabled the first L-smashworks splitter (Libav+L) in the settings and now it indexes my mp4 file in just fine! Can't explain that?? Still get breakup in the audio though.

I can't use the new MotionTracking MKII filter, I'm still running a Q9300 CPU. It won't even show up in the filter list and Aviutl crashes on exit. All is well again after deleting files.

Try this SSE2 build↓

The "Easy Privacy" feature seems a bit slower using SSE2 version, but otherwise no big difference.

Post my mp4? Looks like any mp4 on my PC has this audio breakup problem, but only in AviUtl. Mpc-hc and windows media player are both perfect. This is using Lsmashworks only. Directshow is fine.

Looks like it's not the mp4 file, it's the aac audio, I tried a few .mov files also with aac audio and they all have the same breakup when Lsmashworks is used. If no one else has this problem then it must be my PC, but what could be causing it? Some other app loaded that's interfering with Lsmashworks aac audio decoding. What could that be?

You need to post AT LEAST the MediaInfo Report.
Otherwise I'd have NO IDEA what's your actual file format!

try my attached MP4 and see if you get that problem also (a very typical H264+AAC):

Well, this is very weird. I play your file and it breaks up just like all the others so I decide to record it so you can hear it. I open Goldwave to record it and then the breakup dissappears as soon as Goldwave opens! If I shut down Goldwave during playback, breakup returns. So I try another recorder, Reaper, same thing happens. Ever heard of this before?

Yes, this version works just fine on my old (?) CPU. The UI is much improved and it seems faster, however it seems the older version (MKI) is slightly more accurate. This one should be just fine for blurring faces and whatnot......

Well I've finally figured out how to motion-track on Z axis with reasonable quality. I'll have to write this shit down before I forget....

Then this is certainly a problem with your computer, probably some sort of device driver or software conflict

A comparison of Mode 1-3, and two (fastest) tracking modes in MK-I

[racer-x]

Every source is different, but in my test source, MK-I gets better results than MK-II.

[poisondeathray]

Nice fat tire laying some tracks racer haha! was that you??

Definitely a live action source is more difficult to track, especially with compression artifacts, motion blur, compared to a clean CG source

[racer-x]

Nice fat tire laying some tracks racer haha! was that you??

No, that was a clip I downloaded from YouTube. I have the same bike however, but without the modifications. Yeah that dude totally destroyed an expensive big tire.

Is there a complete manual available? I see all the links on MaverickTse's site but one document with all the pages would be nice?

I'm trying to find out how to split one video track at one point and create a cross fade (or dissolve) to the part that was split. This is all on the same video track. I'm a little used to Vegas so when I tried the split, I can't move the split parts apart, they all move together. What am I doing wrong. I can't find this in any of the help pages.

No Manual, unless you want to write one?

Anyway you can split a clip just like in Vegas by hitting the "S" key. For example, you want to remove a small section: Go to 1st frame you want to remove and hit "S", got to last frame and hit "S". Now select the clip and hit "Delete". You can now Join the two clips. To add a crossfade transition between the two clips, Right-Click on the track below and select "Add Filter Object" > Scene Change. Align it under the second clip. The default is dissolve / crossfade, but you can change that.

It's not hard to learn if you play around with it a bit.............

If anyone is interested I uploaded a tutorial on how to Motion Track an object in a Z axis using Motion Tracking MK-I filter. I added it in the 1st post of this thread. Have fun......
