I am exploring for the first tutorial video. First, I looked for the screen recording software and found a few pictures, so I asked a friend and recommended
The screen recording expert's software, I tried it, and I used it.
Software Interface:
The software needs to be registered, but it can be done with a registration machine.
Then I started recording. The first step was to generate the format. I chose the wmv Format and clicked the "set" button next to it,
Pop up the following stuff:
I found a button for "uploading HD videos such as Youku". I clicked it and a dialog box popped up:
If you do not care about the text above, click OK to confirm the settings.
Then a short video is recorded and transmitted to Youku.
After Youku's review is complete, I'm dizzy. This video is not blurred, but the words in it cannot be seen clearly,
But I am very clear about watching this video with a player on my computer. Strange.
I searched the internet to find out why Youku performed secondary transcoding. In addition, the video attributes Uploaded By yourself do not conform to Youku's
Rules.
The following are the format requirements for Youku HD videos:
HD and UHD video formats
Resolution requirements:
HD resolution> = 600X480; UHD resolution> = 960X720
Duration requirement: duration> = 30 seconds.
Average bit rate requirements:
1. The average bit rate of the following videos is greater than or equal to 1 Mbps, and the average bit rate is greater than or equal to Mbps:
-H.264/AVC (Advance Video Coding)/AVCHD/X264 usually use MP4, MKV file format, and FLV format.
-RV40/RealVideo 9, usually in RMVB format
-WMV3/WVC1/WMVA/VC-1/Windows Media Video 9, typically in WMV Format
2. The average bit rate of the following videos is greater than or equal to 2 Mbps, and the average bit rate is greater than or equal to 3 Mbps:
-MPEG-4 Visual/Xvid/Divx, typically in AVI, MP4 File Format
3. The average bit rate of the following videos is greater than or equal to 5 Mbps (HD) and greater than or equal to 7.5Mbps (UHD:
-MPEG-2, typically in MPEG/MPG/VOB File Format
-MPEG-1, typically in MPEG/MPG file format
Install Mediainfo to view the video encoding and Bit Rate
Note: the bit rate in the station refers to the average bit rate, which can be simply considered equal to the file size (kb) divided by the playback time (seconds ).
Okay, now it's clear.
So I recorded a 1280*720 resolution, and then used qq audio and video to convert the format from wma to mp4. The parameter settings are as follows:
After the transfer, the video size increased dramatically. It was difficult to transfer the video to Youku for the next time. At first glance, my heart became cooler.
Still unclear, and there are no high-definition logo.
Speechless, is the resolution too high?
I tried to record a 800*600 video. After the same conversion, the video was uploaded to Youku. During watching the video, the magic video was quite clear.
800*600 does not look so cool, but the definition is up. I have to study it if I have time.
