Normally, An intro is usually at the beginning of the video. However, I have seen some videos that use intros after a certain amount of time. Why would this be useful. Well first you can introduce yourself, then put an intro, and then continue with the video. This is very compelling from a deep psychological perspective. It effectively replaces subliminal messages which are illegal.Why Do This?
Depends... In your workflow, you only have 2 options, after the a/v decoder so it only overlays the mainclip or before the encoder so it overlays the Full Thing.authorleon wrote: ↑Sat Feb 13, 2021 1:39 pm
- I noticed that we can add a video layer. How does this particular concept work, and where would you insert it in the workflow.
It basically Supports any installed vfw codec AFIK. Let me Check if there are any h264 vfw decoders... I believe there was some libav based stuff available that would enable Support for mostly any codec.authorleon wrote: ↑Sat Feb 13, 2021 1:39 pm
- I noticed the video layers must be AVI uncompressed, Which would be a massive file. Would it be possible to execute a video layer after number of seconds?
Code: Select all
ffmpeg -i C:\temp\mitaudio.avi -c:v libx264 -an -r 30 c:\temp\30fps.avi
Hey emcodem,emcodem wrote: ↑Sat Feb 20, 2021 6:20 pm Well what about a h264 vfw decoder: https://sourceforge.net/projects/x264vfw/
I just tried it and it seems to work well. For some reason the final picture was turned 180 degrees, not sure if that comes from the h264 decoder.
For my test, i created the "overlay" clip using this commandline:You must take care that the framerate and mostly all other properties of the clips match the input files.Code: Select all
ffmpeg -i C:\temp\mitaudio.avi -c:v libx264 -an -r 30 c:\temp\30fps.avi
Let me know if it worked for you
