Frequently Asked Questions (FAQ) for All Video Converter

1. Video File (.MOV) Opens in VLC and Other Players But Not in Premiere

I had this same issue. I found 2 different solutions for my file.The issue has to do with some kind of codec issue with newer versions of Adobe that no longer support certain .mov encoding types (or something like that)Solution 1: Rename the file extension to .

mp4Believe it or not, this is actually working for some people. Read toward the end of this thread.I tried it myself and was finally able to open the file in Adobe CS5. However, only the audio appeared in the timeline. No video.

Solution 2: Re-encode using VLCThere's a fix in this thread from Sasha L. (dated April 11, 2018) that involves re-encoding the file using VLC. I tried this and it worked. The steps once opening VLC are:When I used this method I was able to export a visual-only video (no audio).

Between the 2 methods I was able to export audio and visual and import them into Adobe Premiere so that they could be combined.Best of luck!


2. 3 outputs from one ATI card (HD4850)

That card supports (at most) two simultaneous displays. The specs for that chipset tell us it has "Two integrated dual-link DVI display outputs", which means you can plug two monitors into it.The important thing to recognize here is that a DVI plug supports two signals--one digital, and one analog. But they (in this case) pass the same signal. A DVI-to-VGA adaptor simply ignores the digital signal, and passes the analog signal on to your monitor.If your card has three plugs, one of which is VGA, it basically just means it has a built-in DVI-to-VGA adaptor, so one of the two display outputs is connected to the VGA and (probably) the HDMI port (HDMI is basically DVI minus the analog signal optional sound info--which is irrelevant to a video card).

So think of it as a video card with a DVI port, and a HDMI or VGA port.If you want three monitors, you will need another video card. Your PCI card ought to do the trick, but there can be icky driver issues to deal with. It's always easier to do that with two identical cards (as I do--I have two identical nVidia cards, each with 2 outputs, to drive my 3 monitors).You also might have better luck with another PCI card that uses different drivers


3. Converting a youtube video to mp3 using ffmpeg WITHOUT youtube-dl?

A browser and application-inspecific way is to use owns both the and domains. To download a specific youtube video in any format, simply replace the portion of the URL with either deturl.

com or pwnyoutube.

com (my personal fav).

For example, a movie with the URL www.


com/watch?vabcdefghijk would become www.


com/watch?vabcdefghijk. Follow the instructions on the download page to complete the conversion and download.Out of interest, I checked on new alternatives and discovered ClipGrab. It, like Miro below, is an open-source and cross-platform application. Unlike Miro, however, it includes a built-in video downloader AND converter, one of which is the MP3 format. It doesn't include as many other conversion types as Miro, but you could always convert it with Miro after download if needed.Download the open-source and cross-platform Miro Video Converter (implements ffmpeg)To download/convert youtube videos from a command line (with ffmpeg integration), the aforementioned youtube-dl seems to be the best solution.

I'm not certain why sudo is needed to run youtube-dl. I switched over to linux and successfully completed various tasks without sudo or su -c. My output is below. Let us know where you hit a snag at. (echo's are just for comment purposes)I think I see what went wrong. You were trying to wget a file to a /bin directory and it required su. If you create the directory /bin (e.g. /home/USERNAME/bin), it's still a searchable directory that you have full permissions to.Assuming you were following the install directions listed at github.


html, run mkdir /bin and replace all instances of /usr/local/bin/youtube-dl with /bin/youtube-dl instead. I can verify that this works on my shared hosting provider (Arvixe)


4. How to convert PCM to MP3?

many of the video and audio conversion and almost every video and audio editing program can do that, if there is a mp3 encode codec on the machine like "lame". I would use gold wave they let you try it for a while, and it can batch that process along with filter batching. It should be able to handle 2-4hour files. Super the video converter can also do that, it might not need a MP3 encode codec, just turn off the video, drop one or many files in, and push the button. (super comes with junkware that should be avoided on install) Super can also do video convert.Many video editing programs can "export" the audio seperate, and do not have to have a video nessisarily, Just like Super any video converter that has some parameters could probably do it, like avisynth, and ffmpeg. Mabey even windows movie maker would allow that?One for all, on one side having a program that has to many features is not easy to use, but if you already have something on the machine for doing "Video with Audio" it might be able to do audio only, fast and easy. it may just need a MP3 codec. Searching here on this site for "mp3 convert" comes up with many usefull suggestions , because many of the programs can easily take a PCM uncompressed wave input, all they need to do is the MP3 out.

5. How to find and delete corrupted files to avoid backing them up

Good news we have a somewhat quick test for valid MKV and AVI files.How can I check the integrity of a video file (avi, mpeg, mp4)?You can use a feature in ffmpeg video converter: if you will specify it to recode video to nothing it will just read input file and report any errors that will appear. This is very fast process because video frames are just being read, checked and silently dropped.

Loop though all avi and mkv files with:Example loop for all files in one directory: (add for /R to use recursion)Windows For Loops infoEdit Here is the Linux bash version I tested works:Now grep error log for which files are bad and delete them. I dont know what the output looks like so you may want to post sample output for assistance with that last step or split into another question.Example output with corrupt file (chopped off end of file), errors can vary significantly:.

7. How can I convert an AVI file to a Blackberry-compatible format?

You can use Avidemux. It also provides good editing features.WinFF is another option, only for video conversions. As the app site says:WinFF is a GUI for the command line video converter, FFMPEG. It will convert most any video file that FFmpeg will convert. WinFF does multiple files in multiple formats at one time. You can for example convert mpeg's, flv's, and mov's, all into avi's all at once. WinFF is available for Windows 95, 98 , ME, NT, XP, VISTA, and Debian, Ubuntu, Redhat based GNU/Linux distributions.

ffmpeg is really powerful but it might be tricky to use for many users. WinFF provides a GUI for it and makes it easier to use.Edit:Mobile Media Converter is another good option.

Application descriptions:The Mobile Media Converter is a free video and audio converter for converting between popular desktop media formats like MP3, Windows Media Audio (wma), Ogg Vorbis Audio (ogg), Wave Audio (wav), MPEG video, AVI, Windows Media Video (wmv), Flash Video (flv), QuickTime Video (mov) and commonly used mobile devices/phones formats like AMR audio (amr) and 3GP video. iPod/iPhone and PSP compatible MP4 video are supported. Moreover, you can remove and add new formats or devices through the internet.

An integrated YoutTube downloader is available for direct downloading and converting to any of these formats. You can trim your clips for ringtone creation or any other purpose and crop your videos for removing up/down black bars or other unwanted parts of the image. Additionally, embedded subtitles can be encoded onto the video for watching movies or shows with subtitles on devices that does not supports them.

The program has a very easy-to-use and simple GUI (Graphical User Interface) that helps even the most amateur user. Most of the times, the only data that you must enter is the input file(s) or just drag 'n' drop the input file(s)! The 3GP and AMR formats are used by mobile phones for MMS, video and sound recordings, etc

Problems of Phased Array Ground Penetrating Radar Detection System
Although GPR has been widely used in hydrology, engineering, environment and other fields, many basic theoretical and technical problems have not been fundamentally solved, so the real advantages of GPR have not been brought into full play.The main problems existing in GPR technology include:1) The detection depth is shallow, and the contradiction between detection depth and resolution cannot be overcome. Increasing detection depth means sacrificing detection resolution;2) Multiple spread and other clutter jamming are serious, and there has been no good elimination method, which exists in radars at home and abroad;3) The influence of medium unevenness is great and can not be eliminated, resulting in difficulty in obtaining necessary velocity data;4) The data collection method of single sending and single receiving can provide limited information for post-processing and interpretation.The above problems are fatal defects for GPR. Although many geophysicists, electromagnetic experts and geophysical workers have done a lot of research and improvement on radar antenna design, signal processing and underground target imaging, these works are only partial modifications to the existing GPR system. In order to develop GPR technology, we must update our ideas and solve the problems from the fundamental principle.In view of this situation, experts proposed to develop a new GPR system - phased array GPR detection system in 1999.The basic research idea is to replace the current monopole radar antenna with the phased array radar antenna by using the relatively mature military phased array radar technology. Its purpose is to gather the electromagnetic wave into a narrow beam to transmit underground (or detection object) through the phased array technology, and receive the radar echo signal reflected by the target by using the multi-channel acquisition technology, The advanced data processing is carried out, and finally the three-dimensional image of the internal structure of the detection object is given.Development prospect of ground penetrating radar technologyIt is worth noting that at present, similar products have appeared in the market, such as RIS antenna array series of a company, but these products simply combine multiple monopole antennas into array antennas, which is essentially different from the idea of phased array ground penetrating radar.Because the phased array radar converges the electromagnetic wave into a narrow beam by controlling the phase delay of each channel, the energy is concentrated and the wave front diffusion is small. Therefore, the detection depth of the phased array radar is much larger under the condition of the same frequency and transmission power; On the contrary, under the same detection depth, phased array radar can improve the transmission power, so its resolution is much higher than the existing radar. In addition, since the spherical wave transmission is changed to beam transmission, the influence of medium heterogeneity is much smaller.Secondly, the phased array radar works in a continuous scanning mode and can scan in multiple directions. Therefore, the amount of information is much larger than that of the existing ground penetrating radar. For some special detection work, such as the quality detection of embankment cut-off wall, its role is unmatched by the existing ground penetrating radar (monopole antenna radar can not detect the joints, forks and other defects of embankment cut-off wall at all).Because phased array radar is a multi-channel received signal, multi-channel superposition can be carried out, just like the multiple coverage technology of reflection seismic exploration. Therefore, multiple interference can be greatly eliminated, which is difficult for existing radars. The antenna of high frequency (600mhz-1ghz) phased array ground penetrating radar can be made smaller, and its advantages are unmatched by the existing ground penetrating radar in shallow detection.At present, the system prototype has been completed. The carrier free pulse working system with center frequency of 900MHz is adopted, and the transmitting and receiving antennas are separated. 16 (4 × 4) Transmit channel forming, beam aggregation and scanning 16 (4) × 4) The channel receives the echo, and the optional scanning angles are - 36 °, - 24 °, - 12 °, 0 °, 12 °, 24 ° and 36 °.The software part of the system has rich data processing functions. The main conventional processing includes filtering, gain adjustment, static and dynamic correction, deconvolution, complex signal analysis, time-frequency analysis, etc., and multi-channel data processing, such as velocity analysis, superposition technology, coherence analysis technology, array signal processing, etc. And weak signal extraction, target automatic recognition and inversion interpretation under various clutter interference. A large number of field experiments on concrete detection in Yichang Three Gorges dam are carried out. The experimental results show that the spotlight scanning function of phased array radar has been realized, the penetration depth is greater than 1.5m and the resolution is higher than that of ordinary radar.Editing: hfy
