Windows Media Video Compression Using Adobe Premiere Pro

I’ve written this tutorial for anybody who makes use of adobe premiere professional and desires to seek out out one of the simplest ways to compress a video utilizing “Windows Media Video”.

I cowl issues like what bitrate to make use of with what decision and body price in addition to what a number of of the completely different settings do and imply. Find out for your self and take a learn…

Getting to Adobe Media Encoder

1. Render all unrendered footage in case you haven’t executed so already in premiere professional

2. Now go, File >> Export >> Adobe Media Encoder

three. Select “Windows Media” from the format drop down listing

four. Then, from the preset drop down listing, choose one thing like “WMV9 720 25p” (doesn’t actually matter what you select)

Video Settings

1. Select “Video” on the left hand aspect of the Adobe Media Encoder

2. Under Video, be certain…

  • Select “Windows Media Video 9” because the codec
  • Leave “Allow Interlaced Processing” Unticked
  • Under Bitrate Settings, Select “Two” encoding passes and ensure the mode is “Variable Constrained”. This provides method higher outcomes in comparison with a single encoding go

Audio Settings

1. Select “Audio” on the left hand aspect of the Adobe Media Encoder

2. Under Audio, be certain…

  • Select “Windows Media Audio 9.1” because the audio codec
  • Under Bitrate Settings, Select “Two” encoding passes and ensure the mode is “Constant”. This will be certain the audio high quality stays the identical the entire method by means of the video

Audience Settings

1. Select “Audiences” on the left hand aspect of the Adobe Media Encoder

2. Audiences is a very powerful half as that is the place you really set the standard and the file dimension

three. Now, choose your required body price, it’s normally greatest to maintain it at its unique stage. But, say you’re unique stage is 50 frames a second, cut back it to 25. If you’re going for a very small file, then you definately’d wish to convey your fps right down to 20 or 15, however 25 will at all times improve the footage as it’ll seem quite a bit smoother.

four. For Pixel Aspect Ratio, set it to nevertheless you’re unique footage is about. If you’re modifying footage shot on the pc, then sq. pixels gives you the perfect outcomes.

5. Frame Width and Frame Height is an enormous issue for when contemplating picture high quality with file dimension. You type of must match them each up. In idea, for easy scenes like a detailed up of a human face “1 bit” per 200 pixels will provide good outcomes,it’s possible you’ll even wish to strive 250 pixels per bit. But with a extra complicated scene which incorporates perhaps surroundings and shrubs or a quick motion video.and many others, you’d wish to goal round “1 bit” per 100 pixels (no the place over 140 pixels per bit). To work this out, merely have a look at all of the scenes in your video. If your scenes differ quite a bit by way of color and complexity, then you definately need lesser pixels per bit, it will improve file dimension (or cut back picture dimension) however will provide method higher outcomes in any other case. On the opposite hand, in case you’re video incorporates lengthy interviews with a nonetheless background. Then the compressor will be capable to produce good outcomes with a excessive pixel per bit price.

6. Now, transferring right down to the fundamental audio settings, in case you’re video incorporates lots of sound and the sound is absolutely necessary within the video. Then you wont wish to go below 96kb/s, however I normally want to make use of 160kb/s or 128kb/s as in case you examine the 160kb/s bitrate of the audio to the say 5000 bitrate of the video, you possibly can see that the audio isn’t going to impact file dimension a lot on this case. The larger your video bitrate, the lesser the impression the audio can have on the filesize. Use CBR audio, not (A/V) CBR audio. Use stereo in case your sound differs from channel to channel (most music does).

7. Back to the Video now, Set Decoder Complexity to Auto

eight. For key body interval, you probably have a excessive motion video with complicated scenes, set this to about 1 or 2. On the opposite hand, you probably have not so complicated scenes like an interview with a nonetheless background, then you possibly can increase this as much as about 10.

9. Leave buffer dimension as default

10. Now, right here is the nice bit. Because earlier on, we set a Video Encoding mode to a Two go encode with a variable however constrained bitrate. This means we will now give a most and common bitrate. It will use the utmost bitrate within the extra complicated scenes and can use the common bitrate for regular scenes. Now, setting your bitrate is necessary. This is mainly, the place we shove all our decision and different information, in to a tightly packaged file. If you bundle your file to tight, bits of knowledge begin oozing out the corners which is why it’s necessary to bundle your video tight, however not too tight. Let’s say we’ve got a quite complicated video which is pretty quick paced with plenty of completely different colors and scenes. We set our decision to 1024×768 with a body price of 25 and we wish glorious high quality, however a small file dimension.

Ok, let’s put what we learnt in to play. Ok, 1024 multiplied by 768 offers us 786000 pixels. That signifies that each single body will include 786000 pixels. If our video is operating at 25fps, that’s 19.2 million pixels a second. The method compressors work, is that they search for similarities throughout a number of frames they usually try to share the info. Sometimes, if you set the bitrate too low, it simply can’t take care of that information so it must throw away some pixels. The decrease the bitrate, the extra pixels get thrown round or ripped up.

11. Now, we have to set the bitrate. So, seeing our scene is pretty complicated, and we wish good high quality, I believe 130 pixels per bit will probably be wonderful. So, lets divide 786000 by 130. This offers us 6040 bits. So, 6000 bits a second is what we want. We’ll set 6000 as the height and 5000 as the common. Now, 5000 bits a second will produce a pretty big file by way of the web, however bear in mind, we’re utilizing a decision of 1024×768 which could be very large by way of the web, however we wish viewers to see “all” the work we’ve got put in to it.

12. Now, as soon as the bitrate is about, we’ve got our buffer dimension, the bigger your bit price, the bigger you need your buffer dimension. In this case, a buffer of 20/25 will probably be wonderful (buffer normally doesn’t impact something).

Saving

1. Now, save the preset purchase hitting the floppy disk icon up the highest of the Adobe Encoder Window. But, earlier than you do this, place a remark for the preset if you would like.

2. Now, hit OK on the backside of the window which can then immediate you for a location to reserve it. It may even give an estimated file dimension based mostly in your video size and also you’re peak information price (for each the video and audio). But seeing we’re utilizing a variable bit price, this estimate is normally larger than the top consequence.

three. Let it render out, then get pleasure from.

Tips

  • It’s normally good to set your work space to a size of 5 seconds over a posh a part of your video, that method, you are able to do check renders to seek out the perfect bit price
  • If you get errors whereas exporting and you employ a hyperthreading processor or a twin core processor, go to this website to repair the issue. If you don’t get this downside, it could nonetheless be a good suggestion to go to the location and get the brand new adobe media encoder.

I hope you learnt one thing from this tutorial Smiley
