How do you add handles to AE Composition Clips then?

Using MagicLantern, which QScale should I pick (-16 to +16) to best match YouTube’s VBR 1-Pass Target: 12, Max: 17 mbps?

[Steve Brame] “There certainly is. Now all you have to do is decide which standard to lower.”
Not lowering any standard. Videos are going to be on YouTube’s 1080p. That’s all they will ever be played on.
It’s pointless to work buku extra hours to make video 4x the quality that YouTube is capable of, just to have YouTube decrease the quality to it’s own level anyway.
Just like we never shoot in RAW for our photo shoots, since the images will only ever be printed to 8×10 inches max and JPG is just fine for that.

[Walter Soyka] “Then you are trying to violate the quality-speed-cost triangle.
You can reduce quality by recompressing the footage further, you can reduce speed by sending the larger files over the Internet and waiting for them to finish, or you can reduce either margin or consumer price benefit by shipping. You can’t have all three.
Proxy workflow might work,if you upload proxies and begin cutting with them, while simultaneously transferring the larger files (though of course you will lose time compressing the proxies in the first place). Pr doesn’t have a good offline/online workflow, though.
What about hiring an editor in the same locale as your shooter?”
Yes, I can hire an editor in the same locale as the shooting, but then I’d eventually have to hire numerous editors in numerous locations when the business expands, and get all of those editors on the same page in terms of how to cut the video, how to process, in what order, etc for consistent quality.
The triangle can be violated, and I know this from experience. There’s always a “standard” for quality/speed/cost. As long as each characteristic doesn’t go below the “standard” the triangle can remain intact.
For example, right now the video at 330MB/min has fantastic quality but it’s overkill since it’s just going to go on YouTube for streaming. As long as that arm of the triangle doesn’t go below YouTube quality, and the Cost/Speed arms stay the same or even decrease, the triangle remains intact. Becomes stronger, even.

Yes. Too expensive. Margins don’t allow for it.

1. Proxy Media: Is fascinating. So they send me super highly compressed footage (with the exact same filenames as the original), and we have our processor cut and do everything, then we send over the project file.
BUT: what if there’s processing that has to be done on the original media? We run some of our clips through Mercalli camera stabilizer. We cut, then run Mercalli on the clips, then add the transitions.
2. But at the end of the day it’s still too much work for my videographer to process *anything*. She shoots all day, and then she’s tired, and then she repeats. I don’t want to work her to the bone. Short of having her hire her own in-house assistant (literally in house, processing off of her hard drive) just to do the processing… what else can I do? Plus having local processors brings up huge issues with consistent quality.
In the long run, I want to have a consistent video product throughout the nation. I don’t think I can easily do that with 50 different individual photo processors working locally in whatever region the videographers are shooting. I’d much rather have a central processing unit that all the videographers send their files to. It’s much easier to control quality and much easier to synchronize any changes and improvements that we roll out in the future.

Aren’t some formats better for editing than others?
Currently the final format is (from a .mov):
.mp4
H.264
1080p
29.97fps
VBR 1-Pass Target: 12, Max: 17 mbpsIs this a good enough format for further editing?

Well, here’s what I don’t get.
The T2i shoots at 330MB/min. 3 minute’s worth of video clips could be 1GB.
Yet, after all the clips are put together, titles are added, an audio track is added, etc. the resultant 3 minute video is only 250MB. And the quality is fine.
1GB for 3min of original clips vs 250MB for the final 3 minute movie.
What gives? Why can’t I just get 250MB for 3min of original clips, and then come out with a 250MB finished movie?

[Shane Ross] “The format already is highly compressed and light weight. You want to go MORE? I don’t think you can and retain quality. H.264 is darn light. I mean 4GB of footage a day is NOTHING. I guess you haven’t dealt with Uncompressed HD…or even the compressed editing formats of ProRes or DNxHD, that are about 3-4 times larger than H.264.
I just edited a video shot with my T2i…using the native H.264. PPro 5.5, and CS6 (testing that) handled it great.”
It doesn’t matter if 4GB is “nothing.” The fact of the matter is that it is too much to transfer over the internet on a day to day basis between my videographer and the processor. Depending on the number of shoots she does, it can easily balloon to 16GB a day. I can’t seriously expect my videographer to upload 16GB each day and for my processor to download 16GB each day.
We need something smaller that is easily transferable.

Thanks guys!
