With the video codec I'm using I've noticed some lossyness in post processing. With multiple processes it compounds and the result is....well....it's not good. Do you know of a codec that is lossless or close to it with full 1080p?

What is your workflow?

It varies a little but:

1)write a rough script.

2)Prepare the audio files and add the times in min:sec to the script.

3)Begin making clips broken down into act:scene and add transition ideas to the script.

This is the crux of the issue. You need smaller chunks for test renders and it helps with transition effects. I may use up to 3 or 4 layers of processing and a dynamic script.

4)Create transitions, annotations and intro and end credits and log them into the script.

5)load the audio, clips and transitions into the editor in their perspective time tags and render the final cut. <- usually while I sleep!

The video I'm making now is a demonstration. I'm trying to speed up my workflow and make it more efficient. I probably should stick to raw AVIs but I may run across this issue again with compilations.

Hmm... What programs are you using? And what kind of videos are you making? Sorry I'm just a little confused by this workflow. What do you mean by creating transitions and loading them into the editor?

I make my own animations and videos from scratch with open source software. I use Blender3D, Gimp, LMMS and Audacity as my staples.

Ohhhhhhh. Gotcha. Thought that might be the case. Well I don't do that kind of stuff, so all I can really say is reduce the amount of bottlenecking. What editor do you use to bring everything together?

If you ever have to export something that needs to be edited further, do it without compressing the footage. I know the files can be huge, but this is the only way to ensure the best quality. And you can delete whatever copies of the footage you aren't going to use in the future. The only thing you want to compress is your final output.

It's a pretty smooth process even though it's 3 to 4 tier system. The dynamic script keeps it flexible, maintainable and orderly at the same time. It's a matter of time before I run into an issue that will have me considering changing it in a fundamental way though.

I use Blenders video editor. I have a full 3D creation, composition and editing suite at my disposal. A lot of times I can fix mistakes that I made early on or even make additions in the post processing.

Except for the past couple of videos that I've made I've used raw AVIs for the clips. I'm likely going to have to store clips in raw form too as much as I hate to. Guess I was hoping for a new wonder codec.

Eh, yeah. For me, the only way to go is the path of highest possible quality. Even using the best codec in compression still slightly degrades the quality. And that would bother me as the content creator, even if it was hardly noticeable in the final output.

But to each their own I suppose. I use H.264 (high bit rate) for YouTube/Vimeo and it looks pretty sharp. It's really hard to tell the difference between the uncompressed and compressed files when watching on my MacBook Pro.

Animation Codec. Make sure you render at 100% quality.

If you are making a video then preproduction is always rendered out in raw format (you end up with huge files but you keep all of the quality)

the final render that goes out to the public or put up for download, is using a common format such as h.264 (it is a very flexibly format that can get really high levels of compression, or really low levels (pretty close to lossless, it all depends on your target file size)

PS the animation codec only works for 2D video, 3d video or any video that has many gradients will show little to no compression, so all you will end up with is a format that very few video players support and no smaller file size.

All in all, never encode in anything that compresses the video while you are editing it. the compression only happens during the final render.

I've had good experiences with raw AVIs but they're massive at 1080p. I was looking for an alternative.
