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! |

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! |

About 343 seconds (5 minutes, time for a snack). It looks like a video of a cellphone screen :-) With some floating blue rectangles. Thanks for testing that out Paul because it was my first time doing things that I would think others here would also want to do. 1. Record "stuff" on Android & bring it over Wi-Fi to Windows for editing 2. Edit a "video" on Windows with (the best so far) video-editing freeware 3. Upload that video to a registration-free binary upload/download site 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.) The "editing" tasks that had to be surmounted we A. We had to find the "best" (so far) freeware video editor on Windows. B. It had to allow us to edit the video & audio on Windows C. So that private information was redacted (both video & audio) Trust me when I say I would have *loved* to not have to have those floating blue rectangles, which were simply "blank" text boxes where both the font and the background were the same color (and where the only character that doesn't work but there is no error telling you why is the most obvious character of blank "spaces"). My main worry is privacy since uploading videos is harder than uploading images. For uploading images, there are plenty of no-registration web sites, for example: Cube Upload http://cubeupload.com Post Image http://postimage.io Image Titan http://www.imagetitan.com We Take Pic http://wetakepic.com http://pictr.com ImgUr http://imgur.com Bild.Me http://bild.me File Convoy http://fileconvoy.com Share Photo http://share.pho.to Turbo Image Host https://www.turboimagehost.com Tiny Pic http://tinypic.com etc. But I couldn't find a no-registration "video" upload/streaming site, so if you know of one, that would help everyone who needs to upload a video while maintaining privacy. As for the content, I realize and state openly that I admit that a simple voice over would have explained the content sufficiently - but what I need is voice-obfuscation software (to fuel my privacy fetish) so if you know of good Windows voice-obfuscation freeware - that would be a plus. Without voice obfuscation, I was left to popping up little text boxes, which I did in the beginning but I assumed that the specific target audience would see that the video showed things that Android could do five years ago that iOS can't hope to do today (but this Windows thread is NOT about that topic). This Windows thread is just a tribal-knowledge sharing where I'm giving back to the team (who suggested Shotcut in the first place) and asking how to improve the results (which, Lord knows, are amateurish ... I know). The good news is that Shotcut is a winner. It's pretty hard to use (someone just suggested VideoPad Editor freeware, which I'm also testing, but it seems to be really commercial ware in the guise of tease-ware - but time will tell). In the end, the price of freeware is in finding the best one to spend energy on, where Shotcut "seems" to fit the moniker of being the "canonical" free video editor (other than, perhaps, Windows Movie Maker, which technically is "free to me" I guess - but I didn't try it). Thanks for all your helpful advice. I will always try to give back to the ng so that the tribal knowledge increases from all my efforts. |

| 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. |
