Interlaced
6. Deinterlaced video
Interlacing for those that have never heard of it before is to do with your TVs cathode ray tube. Basically it shoots a ray of light at the front of the screen which changes colour as it scans across the screen. Unfortunately they found that by the time the ray had gotten across and down and across and down all the way to the end of the screen the first lines had lost colour. So they invented a second scan field. Now it scans one line, skips a line and then does the other till it hits the bottom and then goes back to the start to do it again filling in the missing lines which keeps the image bright all over. Clever really. When it comes to computers though its very different. Read the rest of this entry »
1. Resolution
YouTube is now in HD and will love you lots if you can match it’s resolution rewarding you with high quality sexy looking videos. The resolution of youTube HD is 1280×720 and if you can match this then YouTube wont have to mess around with the resolution at all when you are uploading your videos.
For non HD content you should aim to have the resolution at 640×360 (16:9) or 480×360 (4:3). as recommended by youTube for smooth results.
2. Bit rates
The bit rate is how many bits there are in your video per second. It’s pretty easy to guess that the more bits her second the more detail and better quality the video will have. Unfortunately if you max this out you may fight that your video files are too large for upload to YouTube =[ as a suggestion aim for your bit rate to be around 6-8Mbps but try maxing it out as far as it will go and keeping under the file size restrictions.
3. Video Compression
Don’t upload uncompressed video, there is no real need and it will just take up unnecessary disk space and your files will be too big. Try using MPEG4(DivX, Xvid)/H.264 for the video and make sure your frame rate is corrected as discussed above. YouTube runs at 30fps (Frames Per Second), it shouldn’t matter what your video frame rate is but if you match this YouTube will have an easier job of making your video look good.
4. Recording Audio
As a note to recording your video, get the audio right at the start. If it’s too quiet your video will suck, try using a tie clip mic or shouting loudly at the camera if that’s what your using. I’ve used an external computer in another room with a long lead to a SM58 on a stand pointed at the subject before and then added the audio track to the video later. If you want your videos to have a high production value you need to make the audio top quality.
5. Audio compression
The use of high quality audio in YouTube videos is debatable. If you are going to upload HD quality video then shouldn’t you upload HD quality audio? But I’ve heard the same people who say to upload HD quality video saying to compress audio to MP3. The way I look at it, if the video is being watched on a 5.1 surround system with HDTV then HD sound would be useful, on a laptop with average quality speakers HD audio is pointless. For me I’d have to say HD video is a lot more noticeable than HD audio so I’d tend to drop the quality on the audio. MP3 or AAC formats will work fine. 44.1khz is CD sampling rate so that’s always a good guide to go on.
Stay tubed for Part.2!
