How does my very first edited video (using Shotcut freeware) look?
How does my very first Windows-edited video (using Shotcut freeware) look?
https://www.sendspace.com/file/gvckbe Thanks to suggestions in this newsgroup, I was able to edit my first MP4 video, which, in this case, was just a screen recording of five-year-old Android 4.3 functionality to show the iOS users that even their newest devices don't have similar capabilities. http://wetakepic.com/images/2017/10/10/wifi1.jpg But the point here is just to ask you what you think of it, and to let you know the fundamental techniques used so that you can do the same should you wish to edit videos from Android to Windows over the LAN. http://wetakepic.com/images/2017/10/10/wifi2.jpg Here's what I did to create that 3-minute video: http://wetakepic.com/images/2017/10/10/wifi3.jpg Android freewa "FRITZ!App WLAN" (de.avm.android.wlanapp) version 1.2.1 "FTP Server (Free)" (be.ppareit.sw3iftp_free) version 2.14.1 "KingoROOT" (com.kingoapp.apk) version 4.2.5 "RecMe" (com.mobzapp.recme.free) version 2.3.3 Windows freewa "FileZilla" FTP client freeware, version 3.28.0 "Shotcut" video editing freeware, version 17.09.04 Since only on Android 4.4+, did screen recording apparently arrive to the unrooted masses, I used "RecMe" freeware on a KingoRoot rooted Android 4.3 phone and I used "FRITZ!AQpp WLAN" freeware to graph WiFi signal strength over time and I used FTP Server Free to allow the Windows FileZilla client to copy the file wirelessly over the LAN on WiFi. NOTE: If you're on Android 4.4+, you have more options for screen recording than I did on Android 4.3 where I used "RecMe" to record the screen. Check RecMe settings to ensure the smallest decent quality video size: Storage: /storage/emulated/0/recordings/record_yyyymmdd_hhmmss.{mp4,mkv} File type: (MP4) or MKV Audio source: Microphone Encoding bitrate: 64 Kbit/s Use hardware encoding: On Resolution: 480p (480x854) Encoding bitrate: 4096 Kbit/s Max framerate: 30 fps Auto rotate: off I transferred the MP4 file over the WiFi LAN using FTP Server (Free) on Android and FileZilla on Windows (SCP would have worked as well, but I've file that the Windows File Explorer is flaky with FTP URUs). On Windows 10, I opened the file in Shotcut freeware. https://www.shotcut.org/download/ Shotcut takes getting used to if you've never edited video before, where a golden rule is to copy the "video preview" to the "timeline" and to always be aware of the current position of your "play head". The fundamental approach is to create a series of delimited start-and-stop points, where you add "filters" that do whatever you need done, which, in my case, was a lot of obfuscated/redacted text that revealed private information that Android recorded. To cut out sections of video was as simple as locating the start and stop points with your "play head", and then "ripple delete" the section. To add an audio track was as simple as downloading an arbitrary MP3 file from any of the license-free sites such as: Creative Commons http://creativecommons.org/legalmusicforvideos Music for Video http://music-for-video.com/ Vimeo Music Store http://vimeo.com/musicstore YouTube Audio Library https://www.youtube.com/audiolibrary etc. And then adding a blank "audio track" and putting the audio into that audio track, fading in and out as desired using "filters". Speaking of filters, basically filters are everything. They're like the nails that the framers use to frame a house. The filters are what I used to redact text. The filter is what I used to mute the original audio. The filters are what I used to fade out the audio at the end. The filters are almost everything. Fundamentally, I created a "text filter" to block out (aka redact) private information, where a drawback was that the redacted area isn't "smart". It's static. That was a pain. A lesson hard learned was that the only character that doesn't work for blocking text is the most logical character you'd use, which is the space character. If you set a filter with a background of blue and a font of blue it will *look* like it's redacted while you preview the file *inside* of Shotcut - but - when you export - the redactions will NOT show up - and there will be no error. The solution, I belatedly learned, was to use any character *other* than the most obvious character, where I used "xxxxx" and that worked just fine. Speaking of exporting, exporting the video was as simply as hitting the export button. This puts together the whole set of clips in the timeline, both audio and video. The number of options on the export are mind boggling; but the defaults seem to work just fine by all accounts. This is getting kind of long, so, that's a quick rendition of the software, steps, and lessons learned. What do you think of the video? https://www.sendspace.com/file/gvckbe |

I know, I pasted the wrong link, the message is from the video hosting site Thank you for trying where I apologize if you couldn't download the MP4 file (it looks like others could), but I see you wanted to watch it in streaming, which I can't blame you. I'd want to do the same. I had searched for registration-free video upload sites that allow streaming, but I couldn't find any. So if you know of one, I'd be glad to upload to that site for you to stream from. The only registration-free sites I know of that will handle the large size of videos are these "binary" upload sites. Send Space https://www.sendspace.com/ File is deleted if not uploaded in 30 days. Users get a link to an ad-filled page. Tiny Upload https://tinyupload.com File Dropper http://www.filedropper.com/ Upload Files https://uploadfiles.io/ Files.FM https://files.fm/ Zippy Share http://www.zippyshare.com/ GeTT http://ge.tt/ Drop Canvas https://dropcanvas.com If one of those works for video streaming by the recipient, I'd be glad to try it. Does anyone know of any video-streaming site that has registration-free uploads? |

Mayayana ... Ae you saying you can *see* through the blacked-out areas such that you can see the underlying SSID's and other BSSID information in the wireless access points? If so, please let me know immediately, as the entire point was to maintain privacy while uploading a video that happened to contain a lot of privacy-revealing information! |

| Ae you saying you can *see* through the blacked-out areas? No. I just meant the video is clear and the blackouts look fine. Whew! Thanks for confirming that the "redacted" SSIDs and BSSIDs remained obscured. My worry, as it would be with EXIF thumbnail information in a JPEG, or "login" information in a Word document, is that I don't know how an MP4 can be "disassembled" out of its component parts. For example, can the original audio (of the grandkids talking in the background) be pulled out easily from the MP4 I uploaded? Or can the underlying areas I thought I obscured be reconstructed out of "layers" such as those we find in PNG files? I don't know. Does anyone know if an MP4 can be "disassembled" such that the original audio and original underlying information that was "redacted" by "obscuring" can easily be recovered? (HINT: I'm not talking about state-sponsored adversaries but just adversaries who happen to be experts on the file formats.) |

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. 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. |

Wastes 10MB out of the 26MB total, and adds nothing to content. Thanks Shadow for that advice to cut the obnoxious free music. In all honesty, I couldn't get Shotcut to cut the original audio track out, which contained the grand kids saying stuff in the background so I didn't want that on there. So I tried to overpower the original audio with the license-free audio - which I also wanted to test out. I could get shotcut to "mute" the original audio - but I was couldn't split the audio track off the video - so I was afraid that the audio could be "extracted" in the download. Since you're the second person to mention the obnoxious audio track, I'll concentrate on learning how to really remove the audio (not just mute it) in Shotcut. Thanks for that advice as this was my first video-editing endeavor using freeware. Neat the way you cut out the MAC addresses (bit pointless, anyone within range can capture them, I learned that the *hardest* thing for video editing freeware to do is to "blur faces" and "follow them" (which is the same thing we want for MAC addresses). So I had to constantly snip the video because I had scrolled up and down to show the various access points (which was a feature of the Android capability). But each time I scrolled, the MAC address moved, so I had to snip and use filters each time it moved. I haven't yet found a freeware video editor that can "follow" a blur, so this limitation may very well simply be a limitation in the freeware that we have to live with (since I don't need to edit videos all that much). and Google logs even your passwords ....) Hmmmmmmm... are you sure? I presume you're talking about how most Android phones are misconfigured by the user to allow Google to capture every SSID/BSSID and GPS location and signal strength that the Android phone can capture. I know that Google "gets" all that information from your neighbor's badly misconfigured Android phones even if you *hide* the broadcast of the SSID and even if you add "_nomap" to the end of the SSID. a. Your access point SSID b. Your access point BSSID (it's the MAC address that is not changeable) c. The GPS location of your neighbor's Android phone tracking you d. The signal strength the Android phone sees of your access point While Google "gets" that information from your neighbor's misconfigured Android phone, AFAIK, Google "says" they scrub that information from the database under those two conditions: a. You hide the SSID broadcast (which has other problems), and/or, b. You appended "_nomap" to the SSID Even so, I didn't know that "passphrases" are captured by your neighbor's misconfigured Android phones. Are you sure about that potential privacy leak? PS To those having trouble with downloads --- just block Google datamining with your hosts file, and you won't be redirected to a login page. I apologize if that site sucks. I did download the video myself after I had uploaded it, but, I don't recall it being a big hassle. Then again, as you noted, I have the MVP Hosts file which blocks over 15 thousand obnoxious web sites, and I'm pretty sure Mayayana has helped me in the past add all the Google crapsites to that list (yes, Mayayana, I'll get to Acrylic DNS someday so that I can use asterisks instead of the HOSTS file static method). To the point of making the download easier for others, I'd be perfectly happy to use some other registration-free upload site to post the video. I posted a few moments ago a list of registration-free "binary" upload sites. I can't find a registration-free "video" upload & streaming download site yet. If anyone knows of a registration-free (probably ad-supported) video-upload and download-streaming site, that would be a bonus! |

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 |
