Some general info about the formats used: YouTube uses 4 container formats and 4 different codecs. It depends on the popularity of the video what codecs are used for your video (see below why). Generally, every of your uploaded videos will be encoded in h.264 and will be muxed into an .flv and .mp4 container. That's the standard and this will happen for ...

tl;dr: Since Youtube reencodes all videos regardless of the upload format, it really isn't that important. Just export your video with a high bitrate to preserve quality. Also see my answer here regarding quality loss caused by Youtube. Long answer: Each reencoding of a video to a compressed format lowers the quality. Usually, that means you'll lose quality ...

There's actually a big difference between the two. If you're on a budget and don't mind that editing video is not as straight forward, then Motion is actually not a bad route to take. Final Cut allows you to use things you've created in Motion as graphical templates. Motion in and of itself is a 2D(/3D) animation app, it wasn't made for video editing. ...

It's not very clear what they mean. If you look further down on the same page it says it accepts 5.1 @ 512 kbps. Recommended audio bitrates for uploads Mono 128 kbps Stereo 384 kbps 5.1 512 kbps YouTube doesn't currently support 5.1 playback. If you upload a 5.1 audio track it gets converted to stereo.

Very broadly speaking, you have a much easier experience obtaining permission if you are not making money from someone else's content. Most copyright laws recognise 'fair use' -- a small quote or a clip that is proof of someone else having said something. It is customary and advisable to put such clip in a box or window to show that the content is being ...

When uploading to YouTube: no (for now...) Your audio needs to be premixed into one stereo (or mono) channel. When using YouTube's online video editor: yes, but you are limited to voice-over and music tracks For more info: http://support.google.com/youtube/bin/answer.py?hl=en&answer=183851 (see point 4. adding audio)

I've answered a similar question some time ago. YouTube added a few codecs since then but all the info there still applys: What codec will my Youtube uploads be output in and what codec should I use to upload? Short answer: Yes if you are concerned about maximum quality a lossless codec or visually lossless codec is the way to go. Re-encoding always means ...

YouTube will re-encode whatever you give it. VP9 is currently too slow to encode. So the best choice is to either: Give it the original footage, or if it is not accepted by YouTube or is too big to upload, then... Re-encode to H.264 ffmpeg ffmpeg will accept just about any input and will provide a great quality output. Development is very active, so it ...

First, get ffmpeg. Generally, you want to give YouTube the highest quality you can because it will re-encode anything you give it, but the formats used in MXF can be mental for uploading. So re-encoding to modern formats for a more manageable upload often makes sense. Example ffmpeg -i input.mxf \ -filter_complex "[0:a:0][0:a:1]amerge" \ -ac 2 -c:v ...

No, you cannot, and this is a good thing for privacy reasons. Using the YouTube Data API v3 you can get general statistics for a list of videos as part of a contentDetails structure: "statistics": { "viewCount": unsigned long, "likeCount": unsigned long, "dislikeCount": unsigned long, "favoriteCount": unsigned long, "commentCount": ...

It's referred to as a jump cut. I would guess that perhaps the Apple ads that used it might have made it popular again, but that's just a guess. The idea behind it is to visually show a change in direction of thought since typically it matches up with the start of another phrase. It jumps the viewer forward in time and makes them aware of a subtle change ...

A coworker has just turned me on to using Warp Stabilizer. It's a built-in effect in Adobe Premiere CS6. Before using this tool, I also used After Effects to smooth and stabilize motion. The difference is outstanding. Warp Stabilizer has worked faster, within my workflow, and more reliable than After Effects stabilization has. This has been huge for me. ...

What format YT output their video depends on various factors. For most ordinary videos they use H264 encoded streams for video (AAC or MP3 for audio) in form of MP4 and FLV container files. These are just containers holding the encoded video data - although the H264-encoded format is no guarantee with FLV-files (or in theory with MP4 files) as they can also ...

Personally I always choose MP4 container and the H.264 codec as this is also the codec YouTube uses in the final video stream. What key-frame rates and compression you need really depends on the footage and it's unfortunately close to impossible to give as a generic answer for this reason. If you have a lot of movements you will need key-frames more often ...

I worked out a satisfactory solution to this problem. It involves adding the 'Computer RGB to Studio RGB' Video FX to each video track in your Vegas Studio project. This effects the rendered file and project quite a lot but appears normal when uploaded to Youtube: Quicktime Youtube It's possible to disable the track Video FX whilst you work on your ...

Why would you want your videos in the .3gp container to begin with? Its a very irrelevant format nowadays, there is practically no device that supports the 3gp container but not MP4 at the same time. Its nothing but a close derivative of MP4, they are very similar container formats holding the same codec. If you want to support a lot of devices using h264 in ...

There's not a lot of point to it. You're using more network bandwidth to download it, and your computer is working harder to display it, but no, you get no additional visible quality from it. In fact, it's likely that you'll get lower quality because the computer has to downsample it before it can display it.


4

No, there is no difference to the human eye (or exceptionally minimal). Your monitor can't display higher quality than it is capable of displaying. The only advantage you would have is if you were to zoom in on part of the image, you would have more detail when you zoomed in. Additionally, as user1118321 pointed out, since 4k is not an even multiple of ...

There could be any number of factors as to why people quit watching a video, but if you want to entice them to stick around, there are a few tricks. Yes, "content is king," but CONTEXT is arguably queen— and let's be honest, who really rules the castle? That is to say— even if your content is great, if you aren't getting it to the right audience, it won't ...

As of now, Youtube doesn't allow multiple soundtracks other than adding a music-track. So you'll need to create multiple videos with voice-over for different languages. Thankfully however this is already automated using a bash script. Demo Video with Automatic voice-over translation from SRT subtitles using eSpeak VoiceOver Script Version 0.3 to convert ...

The reason you are losing contrast is because of the codec you are using to export to. YouTube (as well as Vimeo, and practically every other video website nowadays) works using the H.264 codec. Here are YouTube's instructions for how they'd like videos to be encoded for upload. The TL;DR version of that page: Container: .mp4 Audio Codec: AAC-LC ...

In nearly all countries, copyright protects creative works automatically. Some exceptions and restrictions apply, but unless the author has voluntarily added his work to the public domain or the copyright has expired (common terms are seventy and ninety years after publication or after death of the author), it's safe to assume all songs are copyrighted, ...

you can use something like a M/E switcher with a multiviewer to do this. Just feed the program out into the computer you are streaming from using an input card. I have not used youtube streaming, but I know that justin.tv or other streaming services can use something like OBS to switch between scenes which you can setup with different video inputs in ...

Apparently Youtube took some extra time to process the HD. Both are showing in HD now.

Not sure, which version you're using and I didn't use PowerPoint recently, but as far as I can remember, there is a video export function built in. Might be worth a try. Also there's a list with free video software on Wikipedia, which you can take a look at. Many of them should work for your purpose.

Content trumps everything. People will watch if the story is compelling. You can have crap audio, blocky graphics, bad lighting, noisy video etc but it all falls away if you have something to say that an audience wants to hear. Naturally it's always a good idea to do the best job you can in all the technical areas because you don't want to actively annoy ...

I recommend not to host the video files on your web server, but to upload them to YouTube and only embed the YouTube link on your web page. You can even define that your videos won't show up on searches, but are only served when using the link (from your website). The reason is that these videos add significant load to your web server and bandwidth. And if ...

A common method is split-and-stitch where the file is cut into pieces and sent to multiple servers for transcode. That way you can transcode a file of any length in a fixed amount of time. Telestreams Episode Engine can do this, but I'm sure Google uses something custom coded.

Generally, you are much better having one channel and placing all your videos into this single channel, with different playlists targeting the different audiences. However, I'm assuming the videos are somewhat related. If they are on completely different topics (for example Gardening and Software Programming) you may find that it's better to separate so the ...

As you know there are two solutions, one using your CPU, the other a dedicated GPU. CPU Solution As of today, the CPU solution exit for 4K content, at 60 fps, using x265 or x264 codec. x264 is embededded in OBS in fact, and x264/x265 are known for being the fastest implementation of the standard H264/H265. But, you need a powerful CPU, of course, and then ...
