Youtube: best formats and resolutions for Youtube

Which configuration to choose for the best result

Google Corporation sets a number of requirements and offers many recommendations on video format, codec, bit rate, and resolution to upload to YouTube servers. Clips should be added in the highest resolution available, ensuring high image quality when viewed on large screens, flexibility when converting or rendering after editing.

Videos intended for rental should have a frame size of at least 1080p (Full HD) and an aspect ratio of 16 to 9, the parameters of most modern monitors. For commercial videos where you plan to insert ads, there are no frame size restrictions. However, you should not upload files with frame sizes below 720p at 16: 9 and 480p at 4: 3. With low quality, users with large monitors will find it uncomfortable to watch video footage, they may miss its content.

It is worth knowing that after downloading the video, YouTube always re-converts the material to optimize the playback quality.

In what format can you upload videos to YouTube?
In search of information on what video format is needed to upload to YouTube, you can re-read dozens of pages of information in articles and forums, and when you try to upload a finished file, you run into a problem. The service will not read it. At the same time, a file of a certain format may be compatible with a video hosting service, but the video codec used to encode it is not. To avoid duplicate work, convert or save your work in the following formats:

3GP;
AVI;
CineForm;
DNxHR;
FLV;
HEVC (compressed with H.265 codec);
MOV;
MP4;
MPEG4;
MPEGPS;
ProRes;
WebM;
WMV.

The platform does not support pure audio files, even in such common formats as WAV and MP3. If you want to share your own composition or track that does not violate the rights of its owner, convert the audio to MP4 or other format by adding a video sequence in the form of a cover or a series of thematic images. The following types of files can be used as an audio track:

AAC (in a MOV container);
FLAC;
MP3 (included in a WAV container);
PCM (to WAV).

The resource administration does not give recommendations on the most suitable format, however, it is advisable to give preference to MP4 due to a number of characteristics of the container. For example, most digital devices write in MP4, many media players are sharp for it, the format has a higher compression ratio than AVI.

Video size (resolution and aspect ratio)
The size of a video to upload to YouTube depends on the way it is viewed: in an Internet browser, an application for the Android or iOS mobile platform, a third-party player, and the format: classic horizontal or vertical, shot on a mobile device. The player for mobile platforms adapts to the dimensions of the video, regardless of its orientation, trying to fill the maximum area of the screen with useful content. In this case, the frame is neither stretched nor compressed.

The YouTube video player window has a length-to-height ratio of 16 to 9. Deviating from the royalties is not recommended; this is a classic format, the most widespread in the world.

When playing videos with different settings, gray or white bars may appear in the corners or at the top and bottom of the screen, depending on the active theme. They will be black in the internet browser. Avoid the appearance of these stripes in the video during recording and eliminate them during editing. They make it more difficult to automatically resize the player window.

Best format for Youtube videos

Let’s see what is the format that allows you to retain the highest quality when you upload your video to YouTube. In case you do not know, in fact, once YouTube has acquired the video on its servers, once the upload is finished, it proceeds to recode it and therefore it is important that we provide a file with the highest possible quality and with the specifications that you require.

CODEC

Let’s start with the CODEC. The choice is almost obvious and falls on the ubiquitous H264. Used both in the acquisition phase in many camcorders, and in the distribution phase, it is the best option even when we want to share movies on the Web. The reason is very simple: with the same file size, it provides the best quality. Then, in your editing or encoding program, select it. Of course it would be nice if it ended here. Actually, this algorithm can have variations within it, which I will not explain in detail because it is a very complicated and long speech.

What you need to know is that the H264 profile that YouTube asks us is HIGH, its entropy mode is CABAC and obviously it must be progressive and not interlaced, since we are going to upload a video that will be seen on PC, smartphone and tablets and not on old televisions. Regarding the bit rate, that is the amount of data per second, YouTube tells us that we can leave it automatically, even if as a reference it suggests selecting 8000Kbits / sec for movies in FullHD and 5000 for movies in HD.

We can increase these numbers, but keep in mind that as they grow, the size of the files increases, with more time to load and more space for storage.

CONTAINER

Regarding the extension, that is, the container, mp4 is the best option. Obviously, the frame rate, that is, the number of frames per second, must be the same as what you recorded and edited at.

PHOTOGRAMS TO THE SECOND

For example, if you choose 25 frames per second in these two stages, make sure it is the same when uploading.

AUDIO

Ok, this for the video part. And for the audio?

The choice here falls on the AAC-LC codec, which is obviously stereo and with a sample rate or sample rate of 48Khz.

I know it sounds complicated, but once you dictate these parameters into your encoding program and save them, you just have to select them when exporting and you can forget about them. You may be thinking: but my program already has the ‘export to Youtube’ function, can’t I use it? The quick answer is: you could do it, because in any case they generally have parameters that go more or less well with what YouTube asks us.

However, if you want maximum control and quality, create a preset with the parameters that I told you before, and that I will now quickly summarize:

H264 codec with HIGH profile, CABAC entropy mode and bit rate that can be automatic or 8000 Kbits / second for FullHD movies and 5000kbits / sec for HD movies
extension in mp4
number of frames per second that is the same as the one you recorded and edited as long as it is between 24 and 60 fps
Progressive and non-interlaced movies (for example, 1080p and not 1080i)
48 kHz audio, compressed in AAC-LC

The best format for YouTube videos

The best format for YouTube videos is Codec. The codec is the part of the software that deals with the encoding and decoding of the information that constitutes the transmission of audio or video. The newer codecs also deal with compression and decompression, and therefore when encoding and decoding signals, they use mathematical algorithms that allow you to save storage space at the expense of quality.

Compression

In video file playback, compression is performed using mathematical functions that reduce the number of frames per second or decrease the resolution of the pixels that make up the image. In audio files, compression is performed by removing the frequencies that are not fully perceptible to the human ear and the number of bits that make up the sound information.

Container

The best option for the extension is mp4. The frame rate should be the same as that recorded and edited. The most common container formats are MKV or AVI.

Video formats

Youtube uses the HD 1080p streaming format and the MPEG-2 steam supports the DVD format and is saved with a .MPG extension. If you can’t send the video in MPEG-2 format, choose the MPEG-4 format.

MPEG-2
Audio codec: MPEG Layer II and Dolby AC-3
Audio Bit Rate: 128Kbps or higher
MPEG-4
Video codec: H.264
Audio codec: AAC
Audio Bit Rate: 128Kbps or higher
Minimum audiovisual duration
The minimum duration is 33 seconds, excluding black and static images on the video channel, as well as silence and background noise on the audio channel.

Frame rates

Videos must be at the native frame rate without resampling. As for film originals, a 24fps or 25fps progressive master produces the best results. Frame rates are typically set to 24, 25, or 30 frames per second.

It is not advisable to use resampling techniques as they allow the images to vibrate and often result in poor video quality. Examples: upsampling and transfer like “telecine pulldown”.

Dimensions

Videos must use native aspect ratios, and uploaded videos should never include the black bands of “letterbox” and “pillarbox”. The Youtube player uses frames that allow you to watch videos correctly, without cropped or stretched images.

Video resolution

YouTube would like high definition videos.

For videos intended for sale and rental, you must provide a minimum resolution of 1920 x 1080 with an aspect ratio of 16: 9.
For free or advertising content, YouTube does not require a minimum resolution, but recommends a resolution of at least 1280 x 720 for videos with an aspect ratio of 16: 9 and a resolution of at least 640 x 480 for videos with an aspect ratio. 4: 3.
If the videos are of lower quality, they are not visible to the public on YouTube and are used as a reference for Content ID. These videos generally have a “quarter” resolution, which is 320 x 240. However, the videos must have more than 200 lines to produce effective references.

Bitrate

Bit rates depend on the codec. It is the number of bits per unit of time (attention! We are talking about bits and not bytes), generally measured in KiloBits per second. For the same format, the more information per second, the higher the quality or resolution of the film or audio. Videos should be optimized based on frame rate, aspect ratio, and resolution rather than bitrate.

The best YouTube format

Wondering what is the best YouTube video format? We see this in this guide!

Hello, Today we’ll see what format you can keep the highest quality when you upload a video to YouTube. If you didn’t know that YouTube captured the video on its servers when it was uploaded, it will be encoded again. It is therefore important that we provide you with the highest quality file with our required specifications.

CODEC

Let’s start with CODEC. The choice is obvious and falls into the ubiquitous H264. It is widely used in both the shooting and distribution stages of many cameras and is the best choice even if we want to share movies online. The reason is very simple: having the same file size, it offers the best quality. Select it in your app to edit or encode. Of course, it would be great if it ended here. In fact, there may be variations in this algorithm that I will not explain in detail because it is a very complex and lengthy language.

What you need to know is that the H264 profile that YouTube requires of us is HIGH, its entropy mode is CABAC, and of course it has to be progressive, not intertwined, because we’ll upload the video, which will be on your computer, smartphone, and on a tablet instead of old TVs. In terms of bit rate, i. Y. The amount of data per second, YouTube tells us that we can leave it automatically, even if it shows that we want to choose 8000 Kbit / s for FullHD movies and 5000 HD movies.

We can increase this number, but keep in mind that as files grow, it will take longer to upload files and there will be more space for archiving.

CONTAINER

For an extension, ie a container, mp4 is the best choice. Obviously, the frame rate, i.e. the number of frames per second, should match the one you captured and edited.

FRAMES PR SECOND

For example, if you select 25 frames per second in these two phases, make sure they are the same when loading.

SOUND QUALTY

Okay, as far as the video part is concerned. What about the sound?

The choice depends on the AAC-LC codec, which is obviously stereo and has a sampling rate or sampling rate of 48 kHz.

I know this may sound complicated, but once you have dictated and saved these settings in your encoder, you just need to select them after export and forget about them. Maybe you think: But my app already has an Export to Youtube feature. I can’t use it? Quick Answer: You can do this, because in any case, they usually have settings that more or less meet YouTube’s needs.

However, for maximum control and quality, create a preset with the parameters I’ve given you before, which I’ll summarize quickly:

-H264 codec with high profile, CABAC entropy mode and bit rate, which can be automatic or 8000 Kbit / s for FullHD movies and 5000 Kbit / s for HD movies
-Extension mp4
– Frame rate per second corresponding to recorded and edited, provided it is between 24 and 60 frames per second
– Progressive and non-interlaced movies (e.g. 1080p instead of 1080i)
-48 kHz audio compressed with AAC-LC
