New York Post Production Show
Every time I go to this show, I remember how much I miss NYC.
If you have a photo of me from the show, would you mind dropping it here?
I gave four talks:
- A boot camp on Compression
- Proxies and you in Adobe Premiere Pro
- A talk on VR Productions
- Secondaries in Adobe Premiere Pro
In both of the compression talks (boot camp + proxies), I've included my presets (and extras!) for you to use.
Additionally, not connected to any session is a "search folder" project that you can import into your own
Meanwhile, to get my notes you need to sign up for my very infrequent newsletter.
Quick Editors Retreat 2016 Post
Yes, I have to post, much much more. Both here and on Facebook.
But here is the Bleeding Edge Compression Technqiues
DMDC - Government video show
This is a placeholder while the event goes on. - UPDATED Friday morning.
As I finish sessions, I like to post notes - but I also like to come back and finalize after the show is finished. And yes, this post will change over the next several days.
Presented so far
- 50+ Premiere tips
- Secrets of Compression for online & devices
- Speeding up your Avid workflow with AMA
- 20 extra tips in Premiere for the District Creative Group
- FCPX tips (No notes, but contact info)
- Fix it in post
The difference in size when choosing VBR vs. CBR
The difference in file size has everything to do with data rates and nearly nothing to do with VBR or CBR compression settings.
VBR and CBR is about what type of analysis, if any is done to your file; Data rates are about file size.
Compression Tips like this can be found by attending sessions at Post Production World at NAB (this link includes links to non-PPW sessions)
Way too much on Handbrake, iPad video Compression
I was answering a question over on CreativeCow about iPad Compression...
The poster is saying he's had odd problems with Handbrake and his iPad. And I thought it really belonged cleaned up and on my blog.
On Handbrake and other converters.
I use handbrake (but I also use a bunch of other tools.) It is important that you have the latest handbrake 0.9.8 and you update the presets (the gear at the bottom of the presets allows updating.) If you've been using handbrake for more than a year, one of two common errors are not picking the right preset or not having the preset updated.
Additionally, I've had success with some of the free converters from the Apple App Store (just search video convert.) Another strong free converter (cross platform just in case you're on windows) is the Miro Converter.
Most of the free converters (including handbrake) are generally using the same engine - ffmpeg. Handbrake was originally unique because it could decode DVD VOBs and get around copy protection. It's great, but there are gobs of other well done ffmpeg free converters.
The common Pro Converters (in alphabetical order) Adobe Media Encoder, Apple Compressor, Sorenson Squeeze and Telestream Episode, will absolutely work all the time - it's their product.
On iTunes sync
I've (personally) become a little frustrated on the pro video side with itunes; the sync process/time is at best annoying. I'm a fan of the third party players (like gPlayer, flex player, CineXPlayer) as I can add a video in the apps tab of itunes without having to sync the entire device. One, which I can't recall at the moment, will give you the option to use the hardware chip (or not).
Specific Apple guidelines
Apple has very specific guidelines for what your video has to be to work on the iPad (or other iOS devices.)
I dug up the specs from this webpage
Video formats supported:
- H.264 video up to 1080p, 30 frames per second, High Profile level 4.1 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats
- MPEG‑4 video up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps per channel, 48kHz, stereo audio in .m4v, .mp4, and .mov file format
- Motion JPEG (M-JPEG) up
to 35 Mbps, 1280 by 720 pixels, 30 frames per second, audio in ulaw, PCM
stereo audio in .avi file format
You probably will want the first one - the High Profile 4.1.
The
High profile part refers to a strict set of rules - necessary in this
case because there's a hardware decoder chip that allows playback (this
is similar to what all of these devices are using.)
The
High profile part refers to very strict ways the encoder is supposed to
work (what video space it uses, how b frames should be ordered)
The
4.1 part is the specific sizes, fps and data rate that it supports. It
does specifically 1080p and 720p. I didn't know till I looked that it
specifically does 2048x1024 - probably wasted on all of us anyway.
In conclusion
Yes, some non-broadcast standard sizes may work; other sizes aren't particularly well tested. I do know that if you conform to the specs, it's playable 100% of the time. You just need a good encoder with the right settings.
Understanding Video Compression
Supposedly Compression classes are supposed to be boring. I hope/think/want that our session wasn't. Great questions, fun session, lots of questions answered.
Session notes here
DMDC 2012 - Practical Video Compression in a Post Youtube World
Compression is always a favorite of mine to talk about....
Great talk, great people, great question.
Practical Video Compression in a Post YouTube World
It's one of my favorite sessions to present. It's a dark area with loads of misinformation. Every time I teach this, something is better in the presentation.
Advanced Compression with Avid and Squeeze
Sorenson Squeeze comes with your Avid. It's crucial that you understand how to get your materials from your Avid (beyond just the send to template). We also discussed the basics of compression, how to get better looking YouTube videos, the CUDA acceleration in Squeeze and 360 Sorenson where you can host some content for free.
