can someone show me how to remove hardcoded subtitles from a movie using this program

see attached demo video
(operation in the simplest sense)

so you have to do each subtitles all the way through each frame isnt there no way it can be done all at once, or am i on the wrong track here, btw many thanks for helping me on this most grateful to you

Usually the subtitle line is at the bottom, so you need to find the longest subtitle line in the video, than set the removal area. The removal area will be fixed across all frames in the current video. Unless your subtitle move around... otherwise you only need to set the removal area once.

so in your video how did you delete the subtitle or did you just hit delete on keyboard, so when you go to save movie it will remove all subtitles where you deleted them

[videobruger]

so in your video how did you delete the subtitle

Untick "Display mask".

ok thanks but when i look under filter+ there is no ipprepair listed where do i find this filter and where do i place it

[videobruger]

there is no ipprepair listed

As far as I recall you need to tick it during installaion.

Anyway here.. Place it in Plugin.

thanks i have the IppRepair working now and tried testing a small area of subtitles but how can i stop it blurring the part where subtitles are

as you can see here its blurred

The mask created, using the default setting, may be too large.
Tweaking is required.... (those sliders above)
The ideal mask (the red highlights), should be just slightly larger than the text

You can post a screenshot here (using MPC-HC or VLC, with the subtitle) for us to try tweaking it.

If there are sections without text that got messed, you may use the "profile" feature of AviUtl to switch the plugin on and off, or cut the video in to segments prior subtitle removal, than join them back.

I have been running IppRepair which i am trying to remove subtitles and its now only done 1% after a whole hour so slow, also its hard when using slider as it seems to go past where subtitle is

where is profile feature

here is a screenshot of a long subtitle

[MaverickTse]

I saw your another thread.
and then I know why you AviUtl installation has no IppRepair by default: your CPU is too old.

In this case, use a faster but less complete remover, also in the AviUtl package, regardless of your machine spec.

(I hope you are not working with warez...)

[natty]

Thanks will give that a go many thanks for your help no I am not working with warez

I have just tried what you said to use Imas Uncaption its been running now 30 mins but still not 1% maybe i need faster PC

[yetanotherlogin]

Is there a way to play a video faster while watching a video in AviUtl, à la VLC (using the +/- keys on the keypad)?

Currently, I use the mouse to click in forward sections in the timeline, but I'd rather just watch the video at a faster pace to locate different sections.

Thank you.

Advice : Don't use the Show Desktop icon to hide all active windows without first saving all your work in AviUtl… I lost over an hour's worth of work after AviUtl wouldn't unhide the video part of the screen, which contains the File menu to save the current project on disk

[poisondeathray]

You can watch faster by adjusting the vplay (e.g. if you set it to 200 it will be 2x speed) ; but it's not useful for editing, because it effectively shortens the video on the timeline (e.g. 2x speed would have 1/2 the frames, 1/2 the duration) . And when you set it back to 100, you don't keep your place - so it's not useful for editing. IF you're using it just to preview, it might be useful

Show desktop works here (or windows key + D). You can recall windows by using the window menu or resize windows. For example, if the adv timeline becomes "missing" or "lost" for some reason, you can uncheck, recheckmark it and it will pop back up. Same with other windows. Or if you can only see an sliver of an edge, you can grab it , reposition and resize.

[yetanotherlogin]

Thanks for the infos. What do you mean with the "windows menu" or the "resize windows"?

The screen would only the add-on windows (Tool Window, Adv.Edit, etc.) while the main window was missing, so I couldn't hit File > Save, and just killed the app.

[poisondeathray]

I mean "window" from the main window menu in aviutl (e.g. window=>playback window). But if you can't see it I guess that's not an option

Resizing windows is just grabbing the edge of window and left click and drag. I though that's what you meant by "unhide" part of the screen. But if you can't see even an edge, I guess that's not an option either

If the application hasn't "crashed", you can try alt+tab to select aviutl . There is a shortcut key you can map for "reset windows position". It might not be set by default (fiile=>setting => shortcut key). You can customize your keyboard shortcuts to reset (or any other shortcuts you might use often)

If you have the adv. timeline open, right click in a blank area and select preferences. There is an enable automated backups option (auto save) it should be 5 minutes by default, so you might lose 5 minutes work, not 1 hour, unless you disabled it

Which OS are you using?

[yetanotherlogin]

Windows 7. I didn't think of the ALT-TAB to try and make the main window re-appear.

Right-clicking anywhere in the Adv.Edit timeline doesn't display any pop-up. I'll search elsewhere within AviUtil how to enable auto-save.

Thanks.

Your OS is screwed. Even without any project in place, right-clicking anywhere on the timeline panel should show up a menu.

Maybe anti-virus, malware, broken windows update....

Another possibility is that you have virtual desktop/multi-monitor enabled, and you somehow moved some windows to somewhere the physical monitor cannot show.
In this case, you can try deleting the aviutl.ini file in the installation folder then re-launch aviutl, which will reset the windows locations.

[yetanotherlogin]

Other option: The OS is perfectly fine, but the window doesn't pop-up while AviUtil is busy compiling a video…

7hrs30 left.

Once it's done, I'll try again with VirtualDub + AviSynth, and Corel VideoStudio to see if those are faster options.

[poisondeathray]

Find out where the bottleneck is.

If speed is the concern, you can use faster preset for x264

If you have slow, bottlenecking filters, there maybe other faster filters / approaches you could use instead to get similar results

[yetanotherlogin]

It's done after 18hrs. It looks good enough, considering the venue was badly lit.

I attached the settings (all default).

A couple of questions:
1. Is there another setting I could use besides Preset (medium → ultrafast) to speed things up?
2. Can I export only a few minutes to check how things look instead of waiting for the whole thing?
3. I added a few slides in Layer 3 : Is there a way to get a text list of those, each with its position + duration in the timeline? I searched through the File menu and right-clicking on the layer, but there doesn't seem to be any option that look like that.

Thank you.

1. Is there another setting I could use besides Preset (medium → ultrafast) to speed things up?

I mentioned this in your other thread; but it depends where the process bottleneck is. If it's from some slow filter, then using a faster encoding setting won't help, because the bottleneck occurs before encoding. An analogy would be lets say you have a Ferrari. It goes very fast; a fast car. But you have 3 flat tires, so it doesn't go very fast now. Even if you push the accelerator, you won't go that fast, because the real problem is the flat tires

2. Can I export only a few minutes to check how things look instead of waiting for the whole thing?

Yes, you mark in/out a section. Edit => set selection => enter start/end frames . Or in the preview window (not the playback window), you move the play head and push the in/out buttons (the two button on the bottom right corner, the left is mark in, right is mark out)

3. I added a few slides in Layer 3 : Is there a way to get a text list of those, each with its position + duration in the timeline? I searched through the File menu and right-clicking on the layer, but there doesn't seem to be any option that look like that.

Not sure , Maverick will know. You might be able to look at the project file and see the list

[yetanotherlogin]

Thanks. Is there a newbie-accessible way to find why it's slow, besides the CPU not being on par for video encoding (although ffmpeg takes about an hour to transcode a 90mn MPEG file into MP4)?

[poisondeathray]

The scientific way is to remove filters one by one and test the effect on encoding speed. x264 takes some time to "warm up" ; partly because it does a lookahead first (on some presets and settings) so you need to test a decent length section, not just a few frames for a test run to be valid

You can get a rough idea right away, by testing just a straight encode (no filters, no color correction, nothing) , just input/output . If it's already much slow there compared to standalone x264 or ffmpeg, there is a problem

If you're doing tests, make sure they are "apples to apples" or comparable . So use equivalent settings and conditions with ffmpeg or the comparison test. If you're encoding audio with one , but not the other, it also makes it "unfair" .

Also monitor CPU usage - if you're not at 100%, this suggests a process bottleneck earlier in the chain; eg. a filter might be slow , or single threaded (although there can be other reasons for low CPU usage)

[yetanotherlogin]

I didn't add filters except the Shadow-Highlight filter.

[MaverickTse]

Is the CPU i3/Pentium/Celeron/AMD(A8 or weaker) ?

I've never encountered your problem... but I have some other application(e.g. Kodi/XBMC/Virtualbox...) can have similar syndrome(incomplete/delayed Window drawing) on a weak AMD E450 HTPC occasionally.

[yetanotherlogin]

Is there a way to extract the list of slides that were added to Layer 3, and for each one, the time when it appears and disappears?

Right click on the NLE panel(empty area),
Right click > File > Export object file

Then open the object file（*.EXO） with a text editor.

The timing is recorded as frame number however.
