How does my very first edited video (using Shotcut freeware) look?
He who is Mayayana said on Tue, 10 Oct 2017 15:39:12 -0400:
Isn't the mp4 composed of a series of bitmaps? I don't know. That's why I asked! A bitmap defines a grid of pixels. If you paint black over a rectangle then those pixels are black. They can't be two things. It's not like spraypainting. Great. That's what I want to hear. The only thing I wanted in the video was privacy. The rest was easy. A PNG is just a compressed bitmap with an alpha channel option, which means one can specify a degree of blending with the background when painting the image in order to give an effect of transparency. There are no layers. Didn't we talk about this recently? Someone was asking about image layers. Images don't have layers. Graphic editors can sometimes allow working with layers, and they can save that data in their own formats. But that's not an image with layers. It's a record of digital edits. That function led someone to think that image formats have layers. They do not. A raster image is a bitmap. That's it. PDN has such layers. But not PNG. |

There is no such thing as a raster image (a bitmap, as opposed to mathematically produced vector graphics) that has layers. I can save layers in Paint Shop Pro with the PSP format, but it's not an image with layers. It's just memory backup of what you've done with the image. So if you want to save without merging layers you can do that. But that is not an image and it's not a format that you'd use online or give to others. It's basically the stored data for the "workspace" state, along with undo memory. This is a lot like the text discussion: It helps to understand some of what goes on underneath in order to understand how to work with the medium. |

You can put it practically anywhere. (C:\FFMPEG\bin works for me...) The fun part, is crafting command line invocations for it. Every time I use FFMPEG, I write down the command I used and keep it in my notes file. You'd be surprised how many times you refer to those notes later. If it takes you three hours to figure out what command to use, writing it down is a small additional price to pay. ******* Right now, Zeranoe has both "nightly" builds and Release builds. I tested a "nightly" a couple months ago, and it was broken. Even though statically linked (in the static package), it was missing DLL files. The "Release" version on the other hand, was fine. A few years back, I could grab a nightly and expect it to work. The developers seem to be adding stuff to FFMPEG that's dragging in more DLLs for some reason. And the nightly build hasn't been modified to handle whatever they've done. This could get fixed at any time of course, and I'm only including the warning so a person with limited downloads, doesn't waste their time on the nightly as their first choice. Paul |

Is it the same here, by chance? That would explain the missing dlls. |

Is it the same here, by chance? That would explain the missing dlls. But these builds are supposed to be "static". The executable is pretty big, so all the dependencies are statically linked (in effect, all the DLLs look to be inside the EXE, based on the size). It should not ask for DLLs if built properly. When it start whining about DLLs, you could hunt down the DLLs... but if you did, you'd be admitting to being a "builder" yourself. And building FFMPEG is no small project. I think I tried that once. I like them prebaked now :-) I'm not afraid to build Firefox or Thunderbird or Chromium, but FFMPEG is a *lot* of work. You spend hours looking at ./configure, noting down all the dependencies that have to be built and put in your tree. I can't imagine what a living hell it would be, to do that for Windows DLLs. I think I might have had a moment of weakness, and when I saw it ask for the first DLL, I almost went off on a hunt to look for it. But when the program asked for a couple more DLLs, I said "naw, I've seen this movie before". And moved on to using the release version. Paul |

There is no such thing as a raster image (a bitmap, as opposed to mathematically produced vector graphics) that has layers You're right about "layers" specifically, but what I was talking about is "hidden stuff" like the username in a Word file or the EXIF GPS location or EXIF thumbnail in a JPEG image. All I'm asking is whether there is "hidden" information in an MP4 file that I need to know about to remove ahead of time. Meanwhile, I've created another video, this time of my second-favorite Android software for graphing WiFi signals, where it was *much* easier to redact since I got the hang of things and learned how to *reuse* each block! I also didn't add any obnoxious free music (as per universal request!), and I left the original Android sounds in place (blips and that sort of thing). More importantly, I learned to keep the video more stable, and I learned to make all the editing cuts beforehand. I also learned it's easier to just "ripple delete" (there are all sorts of deletes so you have to learn a new vocabulary) any anomalies than it is to fix them. I also learned how to make "presets" in my GUI so that I don't have to wade through a long list of options. (e.g., the text box should be 200px by 25px with 8x16 characters, each centered horizontally & vertically, etc.) I also added callout text to kind of sort of say what was going on (for Paul, who humorously saw a video with blue boxes jumping around!). The good news is that if you apply a "filter" over a long section, and then later (inevitably) you find you need *more* filters in shorter sections of that long section, when you chop up the section, the first filter gets reproduced in each section, so that's a good thing. The bad thing is you can only select one section at a time (I don't know why it has that severe limitation), so you have to *think* top down when you're applying filters! And as I said before, you really really really have to not hit the keyboard unless you know exactly what's selected and exactly where the play head is at any given moment. Also, the playhead is at the *beginning* of the next frame, so it "looks ahead", which you have to keep in mind when making edits because I was constantly deleting things one frame off on the back end of each section until I etched that fact into my brain. One oddity is that you can't step by "frame" but you have to step by hundredths of a second, where each step seems to be a different multiple of hundredths of a second (I don't understand that yet). I'll upload the second video for a look see when I finish the final edits. I'll also test a second binary-upload/download site for us to find the best for everyone. |

You are completely correct in your assessment that it's a video of a cellphone screen with some floating blue rectangles on it! (Your forgot it also had an obnoxious free music overlay to cover up the grandkid's in the background.) Here's the second video for review of results where the goal was simply: a. Record video/audio on Android 4.3 of the screen running an app b. Copy that MP4 video from Android to Windows over the WiFi LAN c. Edit the video by adding text callouts and redacting private information d. Post the video to a no-registration upload site for others to view The no-registration site of the first video of Fritz! WiFi signal strength monitoring was "sendspace.com"; but people didn't like that site all that much so I'm trying out filedropper.com for this second video of the "WiFi Analyzer" Android capabilities that iOS doesn't have (for God knows what reason Apple restricts iOS functionality so much - but that's an aside). Here is the second video showing "redaction" using opensource Shotcut: http://www.filedropper.com/wifianalyzersignalstrength The first video showing Shotcut redaction was prior posted to sendspace: https://www.sendspace.com/file/gvckbe What do you think of the new Shotcut redaction results? What do you think of this 2nd no-registration video upload/download site? |

What do you think of the video? https://www.sendspace.com/file/gvckbe UPDATE: I've been using Shotcut for weeks now to make other videos where I thank you all for your kind, astute, and purposefully helpful advice. It's so refreshing to have Windows Usenet posters who are intelligent and technical and intentionally helpful as we found here, which is in stark contrast to the iOS gullibles in the iOS newsgroups for which the video was made. The sad observation is that the iOS apologists there *still* can't comprehend that all their wild claims of iOS functionality were purely fictional. In fact, they repeatedly fabricated wholly non-existent iOS functionality, which they claimed only an Android video would disprove. https://youtu.be/7QaABa6DFIo Even though a simple screenshot would disprove what the iOS apologists claimed was iOS functionality, they still claimed that only a video would prove that it wasn't faked! Android: http://wetakepic.com/images/2017/10/11/2wifianalyzer.jpg http://wetakepic.com/images/2017/10/11/fritz_wlan.jpg iOS: http://wetakepic.com/images/2017/10/11/wifi_sweetspots.jpg Hence, the videos were instrumental in pointing out to the iOS gullibles that a speedtest wasn't the same functionality as a measurement of signal strength (which they insisted was the claimed iOS functionality). iOS video by the iOS apologists: http://www.filedropper.com/iosshowingwi-fiovertime-7qaaba6dfio Android video: WiFi Analyzer: http://www.filedropper.com/wifianalyzersignalstrength Fritz: https://www.sendspace.com/file/gvckbe Snit's brazen fabrication of *imaginary iOS functionality*: The full thread is here, where a cognitive adult has to wonder why *none* of the iOS apologists noticed the complete fabrications in the iOS video. https://groups.google.com/d/msg/comp.mobile.ipad/-T7FEXIdU9Q/Dhy-LFH3AwAJ What's strange about the iOS apologists is that they never seem to comprehend actual facts - whereas the Windows people here always seem to comprehend facts. What a difference! Thanks! |

(It's also likely that even if you posted them to iOS newsgroups [assuming there are any such], they'd not be read beyond your first use of the word "apologists".

I know my reply is very late to the thread, so I apologize for that. I've been tinkering around with kdenlive myself for making short videos based on other video I've shot on different occasions and some still jpeg shots I took. I downloaded the shotcut program the other day but haven't actually had a chance to check it out. I actually got the linux version as that's what I plan to run it on. I'm hoping it's as straight forward as the page suggested it might be, pending the variant of Linux I'm using meets the dependency requirements. Mine may/may not, just depends. I'm also test driving minty freshness 18.3 KDE edition which I was surprised to discover is actually more responsive (seems to be anyway) on an older machine that I've already got Mate 17.3 DE on due to expected performance hits if I'd gone with KDE instead. I was running it for hours on a live stick, but, I might take the plunge and let it install on the machine I was experimenting with it on, just to see what happens. So, if I get this shotcut program up and going, I might have questions concerning it. Kdenlive is for the most part self explanatory and that's the primary reason I actually took 18.3 for a test drive last night; as later editions of Kdenlive don't support 17.3 due to the underlying codebase it's built on. I've sadly ran into a few popular? programs now that don't support it, despite it having support officially until 2019. Annoying to say the least. -- To prevent yourself from being a victim of cyber stalking, it's highly recommended you visit he https://tekrider.net/pages/david-brooks-stalker.php ================================================== = 'Guns don't kill people.
