The key is to dial in the bitrate - you'll need about 800kbps video with 100kbps audio to hit 200MB. That's low for for SD resolution, but it might be good enough for you. Also look for software that has an option for 2-pass encoding. Try Expression Encoder, Adobe Media Encoder, or Sorenson Squeeze.

The .mpg and .mpeg extensions are typically associated with MPEG-1 and MPEG-2 files. The structure of these files is different than the .mp4 format used for H.264 video, part of the MPEG-4 family of formats. I suspect VLC and WMP can play the file because they must not be using the file extension to determine file type, they probably parse the file with all ...

A really good program you can use is Handbrake. It's a very popular program among so called "pirates" because it's really good at getting a high quality even at tiny file sizes. And this is with good reason, because the main purpose of Handbrake is, indeed, to make the movies small with high quality. Personally I use it when I distribute my short movies on ...

MP4 has not really an official meaning. But it adds a lot to the MPEG-confusion: MPEG-4 part 14 container: takes an .mp4 file extension, therefore often just called MP4, if it contains audio, it can also have the .m4a extension, for video .m4v, and others (.m4p, .m4b, .m4r). the container format is a derivative of Apple QuickTime's container format (.mov). ...

Banding isn't uncommon in compressed video files, and can is exacerbated by the type and level of compression...there's also the bitrate of the original file and the final output. Lot's of points along the chain can cause banding. But I'd guess it's in your final output. What software are you using for rendering/conversion, and what are the render settings ...

Both MKV and MP4 are container file formats. Container formats define how actual audio, video, subtitle and other data are structured. MKV is an open standard format, while MP4 comes from the ISO and is based on the QuickTime file format.

As it was shot by its creators is kind of a nebulous concept, particularly when compression is involved. Color reproduction varies greatly from one device to another and without a calibrated display and a complete chain of color control going back to the source, you aren't going to get exact. Even then, chances are good that somewhere along the line the ...

ffmpeg will do it for you - http://stackoverflow.com/questions/5887311/ffmpeg-1-image-1-audio-file-1-video If you want to provide good seeking ability, you will need to provide key frames at certain intervals in the encoding, which will increase the size of the video. The codec will encode the whole frame at each of the keyframes but greatly compress the ...

Be aware that you are not changing anything. If I call you Bob, you are still Jac and even then you are probably posting under a different name. If you have software that naively trusts the filename instead of examining the actual binary headers of the file, this can work for you. If the actual format or encoding is wrong then no name change will fix that. ...

Yes, this simple conversion should work fine. Both files are technically mp4 files anyways. Only notable thing is that certain older Apple products, like older versions of appleTV for example, require it to be in m4v format so don't forget to switch it back if your switching between a Mac and a PC if you are using older mac products. By default, m4v files ...

Please note this is UK legislation After some research I found the following in a Government consultation paper: From MODERNISING COPYRIGHT: A modern, robust and flexible framework http://www.ipo.gov.uk/response-2011-copyright-final.pdf There is a clear mismatch between what is permitted by law and the type of private copying that most people think is ...

Unfortunately you are not going to be able to accomplish your goal. Two major factors impact this. First, color processing on different systems is going to differ. This will result in slight differences in the colors that are displayed because many video players apply "enhancements" to video and what you actually see when viewing the video in a browser is ...

Have you tried WebVTT for marking up the subtitles? http://www.w3.org/community/texttracks/2012/08/23/webvtt-support-in-browsers/ http://ie.microsoft.com/testdrive/Graphics/CaptionMaker/ is a surprisingly good tool for making captions. You could also cheat a bit and use Youtube's pretty good voice recognition to perhaps save time transcribing.

Ordinarily, I'd create an Adobe AIR or AIR-for-iOS app to solve this problem. You'd just sychronize your captions to cue points in the video and make 'em visible or invisible with a programmed-in button. You could easily have multiple languages in this way. Are iTunes podcasts just flat-out mp4 movies?

There are different laws regarding ripping DVDs depending on where you live. Two points to consider though: Cases have been made (in the US) that you are within your rights as a license holder to make an archival copy for backup. Having said that, breaking DRM is almost always instantly illegal. Little bit of a catch-22 there for sure. Having said all ...

For best results on any Youtube upload it is always best to follow the recommended video encoding settings. Listed here: https://support.google.com/youtube/answer/1722171?hl=en If you have followed those settings exactly and you are still having a problem it is a localized problem that will not affect everyone. Youtube videos do not play the exact same ...

Use VLC to get the actual frame size. You can go to Tools/media information and from there navigate through the tabs to see what the frame size is. Then enter that information manually into vegas. When you drop your clips in everything should be good to go. If you are still getting blank frames in the rendered video then I would guess that to be a render ...

What is your definition of huge and what is your definition of high quality? Size is directly related to compression and compression is directly inversely related to quality for the most part. Some amount of compression can be had for free using lossless compression or near free with more efficient pattern finding for lossy compression, but for the most ...

I don't think you will find a single clear tutorial as you are talking about a very very broad field and talking about multiple aspects of it. Many, many, many tutorials exist for help with encoding for YouTube or encoding for Bluray. In fact, most Bluray authoring software has pretty good walkthroughs in their help. Youtube itself outlines the basics for ...

Can you provide more details about the source format, as in resolution, video & audio codec details etc? My stock answer is to use ffmpeg with Avanti for the frontend. A starter tutorial is here

I believe this statement: I've a problem while merging 2 h264/mp4 files width the same parameters except length is incorrect. In addition to length your video files have different picture dimensions, and that prevents the merge. Your "input sample" shows a track size of 853x480. The output, however, shows that track #1 is 1024x576 and track #3 if ...

I found that you get better results from gradients in AE when you run in floating point, i.e. 16 or 32bit and output those very bits to the encoder. This means not introducing banding by downsampling it to 8 bit before sending it to the encoder, or even the internal Adobe encoder in AE (which is crap for low bitrates). On the Mac, you might want to export ...

If you are using the Ramp effect then you can increase the Ramp Scatter value which helps decrease banding. Also working in 16 bit or 32 bit rather than 8bit can also help!

Avidemux should do the work. Load File Go to File -> Append and select File To the left of the video window, set video mode to Copy; same for audio mode; set format to MP4. Go to File -> Save -> Video.
