Apply a filter to specific section of video

[hfrmobile]

Tried this tutorial: http://www.howtogeek.com/108584/how-to-quickly-edit-combine-transcode-apply-filters-to-videos-with-avidemux/

I  want to apply a filter to only a specific section of the video but under Windows there is no "Partial" button.

Adding filters to the whole video works, but I just need a short section to add a crop filter ....

Of course, workaround works: Cut video into parts and apply the filter to a specific parts and combine the parts .... But this is a lot of effort I'd like to avoid.

Thanks in advance!

There is no "Partial" button. see using Partial Filter(YouTube)

It is back in 2.6.13 but not with all filters
Only with filters that :
* Dont change framerate
* Dont change size
* Dont need several frames (e.g. deinterlacer)

Thank you for your responses!

Well, I never had the "Partial" button and also not in 2.6.13! Seems to be that it is not available for the Windows edition.

Thank you, found now the "Make Partial" context menu. But even when I just add a black border at the bottom (to hide news flash in a TV show I recorded) I always get:
This filter cannot be made partial.

Even I don't change size etc. as suggested by "mean".

What is the best way to "hide"  a news flash at the bottom of a video?

e.g.

[Jan Gruuthuse]

Blacken border is only for full length video.
My best guess for now:
- Filters: Sharpness: Mplayer delogo2

or create a black png, matching the rectangular part of video you want to mask
- Filters: Add logo: select your BlackRectangular.png

The mark [A ] & [ B] are not filter related, these are cut or saving points.
take note of time in A: [00:05:13.440] and B: [00:07:29.440]
and use these times in Partial Filter: (fill in yourself)
Start time (ms) from A: [00:05:13.440]
End Time (ms) from B: [00:07:29.440]

Well, blackborder.png approach is exactly what I am looking for, but AviDemux crashes when selecting the png file:

Didn't expect that is that much effort to simply "hide a news banner" 

[hfrmobile]

Tried .jpg and it looked better but then Avidemux crashes when selecting "Make partial".

Avidemux also crashes for "Sharpness: Mplayer delogo2" when selecting "Make partial".

No detailed crash information, just getting the "has stopped working" message box ...

[Jan Gruuthuse]

eeks. What windows are you running? and is it 32 or 64-bit operating?
If 64-bit try Aug 21 2016. http://www.avidemux.org/nightly/
Don't use .avi container.
If still issues or 32-bit windows: remux 1st original (.avi) to (.mkv) using mkvtoolnix gui

[hfrmobile]

Thank you all for your support!

Windows 10 Version 1511 (OS Build 10586.545), 64 bit
64-bit Edition of Avidemux.

I ended up doing it "manually":
1. Splitting video
2. grop the part with the banner
3. resized the cropped part
4. concatenated the three parts

Took me 13 minutes to get the desired result 

But for further movies it would be nice to know how to it easier (partial filters) (e.g. when a movie contains more than one banners).

Please never ever use the AVI container for pretty much anything today.

The crash must be Windows specific, WFM on Linux.

Are the restrictions to partial filter applications listed here still current?

I would like to Change FPS different amounts to different sections of a video.
If this is impossible, could I cut the video into multiple projects, Change FPS on the various projects, and then remux them together? Or is variable framerate not supported at all?
If it is not supported, I suppose I would have to go a step further and resample to match framerates.
The purpose is for a music edit sync

[eumagga0x2a]

Yes, they are.

I would like to Change FPS different amounts to different sections of a video.

You would need to export each section to a different video, you should also add "resample fps" to keep the frame rate. If storage is not a limiting factor, I'd recommend using a lossless codec (e.g. Ut Video) for intermediate steps. This all assumes that you don't need A/V to be in sync. If you do, this enormously complicates the task.

Or is variable framerate not supported at all?

You should be able to append and process videos with matching dimensions but differing frame rates and export them to formats like MP4 or MKV (that's it). I would just avoid doing that for many reasons starting with the encoder always assuming a constant frame rate when calculating bitrate.

The purpose is for a music edit sync

I must admit that it doesn't tell me much about what you actually try to accomplish.

[Cormy1]

Is CRF 0 not lossless on x264?
The audio track is being replaced with music, I will edit the video to sync it with the music.
Is that a scenario that gets complicated?
