You can try recoding the video and audio to a different frame rate while keeping the subtitles as they are: ffmpeg -i input.mkv -c:v libx264 -crf 21 -c:a aac -strict experimental -b:a 128k -r 23.98 -c:s copy output.mkv The CRF sets the video quality. Choose something lower for even better quality, like 18. 23 is the default for x264.

I implemented the ffmpeg on my device by making a script that contains the following: #!/bin/bash cd /home/username ffmpeg -f alsa -ac 2 -i pulse -f x11grab -r 25 -s 1366x768 -i :0.0 \ -acodec pcm_s16le VideoRecord.mkv Change the screen resolution to your monitor size (not any other size)! It worked for me, maybe it helps you too!

Your PC is too old for a meaningful upgrade. I would advise against purchasing anything for it, let alone a video card.

Most of the information you've given is pretty redundant, and I ended up using the marketing spec sheet for that model. I'm not going to suggest a card, since purchase recommendations are off topic here. I am going to cover the things you need to consider. A p IV is ridiculously obsolete in this day and age - Nearly everything is 4-5 generations behind ...

No the motherboard video will be tied to whatever video chip is utilized in your CPU. Your discrete video card is completely separate from the motherboard video. If you plug in your monitor to your motherboards video connections, you will draw whatever the CPU video chip is capable of, and same with the discrete video card, if you have a monitor plugged ...

After trial and error, I have discovered the issue: Acer monitors have a feature called "Detect Video", which apparently will attempt to determine video playback and then proceed to fade out the rest of the screen into grayscale. Unfortunately, this feature also affects video games. So to fix I went into monitor setup menu and disabled this feature - set ...

I'm pretty sure it should be udp://@:1234 But it is also possible that VLC is interpreting the @ as listening on an IPv6 port instead of IPv4, in which case this page suggests that using udp://@0.0.0.0:1234 may get it to listen on an IPv4 port.

I'd use a Firefox add-on like Video DownloadHelper, or any of the many other similar add-ons, to download any web video clips. Webpage designers don't generally want people to save their videos easily.

Connect filters with commas. A linear sequence of one or more filters makes a filterchain. Connect filterchains with semicolons to create a filtergraph. See Filtering Introduction and Filtergraph Description for more detailed info. Example: -filter_complex \ "[0:v]filter_0,filter_1,filter_2[chain1]; \ [1:v]filter_3,filter_4,filter_5[chain2]; \ ...

It's slow because the script has to find all the names of all the videos before it can pick a random one. Searching for all those files takes time. I can't think of an easy way to get around that. One thing you could do however is to make a pair of scripts. The first one creates a list of the video files and puts it in a file ("videos.txt"): $formats = ...

Notice; on Windows if you are using concat with a textfile the paths in the textfile need to be relative to the output path. E.g. ffmpeg -f concat file.txt "C:\foo\file.mp4 If your files are located in the directory C:\temp\bar.mp4 your textfile looks like this: file ..\temp\bar.mp4 ...

You don't need to create the overlay mov as a separate step. First create the overlay like a movie in this way: -loop 1 -i watermark.png Then use a fade filter to fade in for 4 seconds (that is 100 frames): fade=in:0:100 And then delay it by 10 seconds to start later in this way: setpts=PTS-STARTPTS+10/TB Your command then becomes: ffmpeg ...

That mp4 is only 6 seconds long, and the audio stream is a different length than the video, I was able to sync the two and get rid of the DTS errors by doing the following though: ffmpeg -i op.mp4 -ss 00:00:00.11 -t 00:00:06.00 -vn -y op.wav ffmpeg -i op.mp4 -ss 0.010000 -t 00:00:06 -vcodec rawvideo -an -y op.avi ffmpeg -i op.avi -i op.wav -b:v 590k -b:a ...

Found answer here: Note: Firefox currently uses OpenH264 only for WebRTC and not for the tag, because OpenH264 does not yet support the high profile format frequently used for streaming video. We will reconsider this once support has been added.

You want to move the moov atom to the beginning. While encoding you can use: ffmpeg -i inputfile [other parameters] -movflags +faststart outputfile.mp4 If they have been encoded already, you can simply copy streams without re-encoding: ffmpeg -i input.mp4 -codec copy -map 0 -movflags +faststart output.mp4 You can also use the qt-fasstart tool. ...

There might be a single command to do all of this but because you're trying to trim and combine clips the simplest method I could find was to break the process into three parts. Start by using ffmpeg to trim the guide clip into 3 sections like this: $ ffmpeg -i guide.mp4 -t 5 guide-out-1.mp4 $ ffmpeg -i guide.mp4 -ss 00:09 -t 9 guide-out-2.mp4 $ ffmpeg -i ...

Try using Handbrake, it is for both Windows and Mac and can convert the files to a smaller size and keep the video frame size (ie: 1920*1080) or you can choose a smaller frame size. It does give you various options for Web, iPod, iPhone, PSP, etc. I use it all the time to convert my wedding films and other video work to upload to the Web (Vimeo, Youtube)

I am a professional VFX artist, and the best way to do it is just take stills. We still do this kind of thing on set for small pieces of film that need to look like live action but can't quite be filmed directly. Even if you have a registration mark on your pages, it's hard to pull out the ones with motion blur. Your best bet (least time-consuming during ...

Your blueray player is likely using HDCP. To attach the blueray player to your computer you would have to find a capture card that supports HDCP. To the best of my knowledge such a device does not exist. It is my understanding that Monitors with HDMI ports are HDCP compliant. Therefore you can hook the blue-ray player up to the monitor. However as you ...

according to the system specs for that mainboard (http://www.gigabyte.com/products/product-page.aspx?pid=4745#sp) you need to have a CPU with built-in graphics - exactly as Journeyman suggested.

My guess would be while your board supports an igpu but your processor dosen't have one. You mentioned a Athlon X4 760K (on chat) - which by all accounts, dosen't have a IGPU. You'd want an A series processor for that.

Many NVidia and ATI/AMD graphics cards support this natively. NVidia's feature is called NVidia Surround and ATI/AMD's is called AMD Eyefinity. NVidia has a guide on how to set up Surround here. AMD has a guide on how to set up Eyefinity here. Both of these essentially present a single frame buffer to the operating system, so the OS thinks that there is ...
