Cant get utube to publish my tenminmixes in full
Youtube imposes a maximum limit of 10 minutes duration for each video and 100 MB max file size.
Since your vids are under the 10 min limit, you should look at the file size as the offending party. If it is over 100 MB, thats the problem.
To reduce the file size you need to understand what a CODEC(COder-DECoder) is and how CODECs can be used to make video files smaller for uploading to Youtube.
The file you want to up-load has two parts, audio and video, Each part uses a different type of codec to encode and save the "movie" you created with your video editing program.
The most common and efficient video/audio codecs used on Youtube are MPEG-4 and MP3.
If your video app is not set to encode audio to MP3, you are probably encoding the audio into a raw uncompressed WAV format (pronounced wave). Uncompressed WAV files are very large compared to the MP3 format.
Setting the audio bitrate can be confusing. To keep it as simple as possible, I suggest setting the Bitrate to 128 kb/s STEREO if the video has music or 96 kb/s MONO if it is just people talking. Set the Sampling rate to 44100 Hz (or 44.1Khz)
AAC is another Audio format. The same sampling and bitrates apply.
The next thing you want to look at is the Video resolution and type of file you are saving/recording to.
Since you are recording from a webcam, you may be using a propriatary codec that came with the camera. If this is the case, then you need to let me know what brand camera and software you are using.
Most video cameras, including web-cams, use non-proprietary formats that can generate very large (but high resolution) files. For example: .avi & .mpg.
You want to record at the highests resolution you can, BUT, you will save it later to a lower resolution compressed file.
Many webcams can record at 800x600 and 640x480, but the file you will save for Youtube may be 320x240, 480x360 or 640x480. The higher the numbers the higher the resolution, but also the larger the file size.
Also, the more motion there is in a video, the larger the file will be. So, if you have a lot of action and need to "squeeze" it in (compress) the video, use a lower output resolution (320x240). If it is an interview type video, where the background stays the same, you may get away with a higher resolution (640x480) if you want a sharper image.
When recordings from the camera are saved as .avi, .mov or .mpg, you will have to change the output format in your video editing program to mp4 (H.264) format.
You may also be able to set your webcam to record directly to the mp4 format, which would be ideal, if you do not plan on editing your video. Then you can simply record and upload.
The bottom line.
When you are done editing your movie and are ready to save it.
Find where you can set or change output options in the editing app.
Set the audio and video bitrates and resolution to those best suited to your needs.
Change the output type to MP4, aka H.264 (for video) and MP3 or AAC (for audio).
Click save, wait a bit, upload your video to YT for the world to see and revel in the glory of being a producer.
