Video Editing on a PC

I purchased a Mac Pro and Final Cut Studio to do my video editing, simply because I felt that PC solutions were just not there.

Adobe Encore is a joke, the only thing it was good for was crashing (and thinning out your wallet).

Sony Vegas was a descent application (and solid), but difficult to use and didn’t seem to expose as much control as I wanted over DVD production.

Times change; and now I’m not as concerned with DVD production as I am with just video editing, and two of my friends have shown interest in video editing and really don’t want to invest in a Mac (there is only one real choice for video editing from Apple, and that’s a Mac Pro, and the combination of the hardware and software is a little scary).

One of my other friends has used Vegas for quite awhile, and he’s been happy with it (of course he’s never done video editing on a Mac).

I’ve decided my project for the next several days will be to evaluate Sony Vega Pro 9.  I’ll try it out on Windows 7 and write a BLOG post that tries to detail the strengths and weaknesses without directly comparing it to Final Cut Studio; though I may use Final Cut Studio as the “standard” for what a high end video editing suite should do.

Video Encoding

A little over a year ago one of my friends with a Mac wanted to get into re-encoding video; I knew about the tools to do it on a PC, but none of the tools really had a OS-X port at that time, so I set out on a quest to find tools that could enable a person who didn’t know much about video encoding to accomplish it.

One of the first tools I stumbled on was HandBrake; it was an Open Source project leveraging off of a number of other Open Source products intended on creating a cross platform suite of tools for video encoding that was reasonably straight forward to use and produced reasonable good results.

Well, the version I tested was a near total failure… but the project showed promise and I keep tabs on it for quite some time.

Over the past year it’s steadily improved.  In fact, I’m probably being a little hard on it, since right after I played with an early version a much improved version was available that did work, and did allow my friend to accomplish what he wanted.

Last month HandBrake released a new version — a much improved version.

With Windows, OS-X, and Linux versions you can try out HandBrake for yourself and see the results.

I did two separate tests (and for some reason I always use the same two DVD titles — Saving Private Ryan, and Lord of the Rings — the reason is that both movies have a wide range of  video type from near still images to sweeping panoramic views to everything in motion (blowing up)…

I had two separate machines (a Q9300 and a Q9400 both with 8GB of DDR2) doing the encodes, and did both normal and high profiles; one test was H.264 into a MPEG4 container with AAC created from the AC3 5.1 track; the other was H.264 into a MKV container with AAC created from the AC3 5.1 track in addition to AC3 5.1 pass-through and Dolby Surround pass-through with [soft] subtitles.

For the high profiles: Lord of the Rings took a little over three hours; Saving Private Ryan took just under two and a half hours — so don’t get in a hurry, in fact, run it over night and don’t bother the computer(s).

The high profile achieved about a 2:1 reduction in size; the normal profile achieved about a 4:1 reduction in size.  The high profile’s video was stunning, the normal profile’s video was acceptable.  The AAC audio was acceptable; the AC3 5.1 was identical to the source, and in perfect sync.

There are a number of advantages to keeping your video in a MPEG4 or MKV container verses a DVD image… it’s much easier to catalog and play, and of course it’s smaller (well, you could keep the MPEG2-TS in a MKV and it would be identically sized, but I see little reason for that).

The downside of RIPping your DVDs is that you lose the navigation stream and the extra material.  Do you care???

HandBrake will read source material in just about any format imaginable (and in almost any container as well)… you can take a look at it’s capabilities and features online.

I’ve got some VCR capture streams in DV video that I’m encoding now — trying a few of the more advanced settings in HandBrake to see how it works (well, that’s not really testing HandBrake, that’s testing the H.264 encoder).  My expectation is that once I get the settings right, it will do a fine job; but with video captures you should never expect the first try to be the best (well, I’m never that lucky).

While HandBrake is very easy to use, your ability to get really good results from it is going to partially depend on how willing you are to learn a little about video re-encoding (which will require a little reading and a little experimentation).   But that said, NO product is going to magically just do the right thing in every case…

Overall I would say that HandBrake is one of the best video encoders you’re going to find, and you cannot beat the price — FREE!

Here’s some additional notes.

For Windows 7 you will want to download the DivX trial and just install the MKV splitter (nothing else is needed) so that Windows 7 can play media in a MKV container using it’s native CODECs.

With Windows Media Play 12 and Media Center I haven’t figured out how to switch audio streams; so make sure you encode with the audio stream you want as a default as the first stream.  With Media Player Classic and Media Player Classic Home Cinema it’s easy to select the audio stream.  Also, Windows Media Player will not render AC3 pass-through streams, it will just pass them through the SPDIF/Toslink to your receiver — so you won’t get any sound if you’re trying to play it on your PC.

Don’t delete any of your source material until you are certain that you are happy with the results; and you might want to backup your source material and keep it for six months or so just to be sure (yeah — I know it’s big; but a DVD will fit on a DVD).

Mac Pro upgrade

I updated my Mac Pro to OS-X 10.9 Mavericks last weekend, and after doing that the iMovie update wouldn’t install, it claimed that the ATI X1900XT video card that shipped with it wasn’t compatible; which with the help of one of my friends at Apple we determined that the new version of iMovie (like Final Cut Pro) wanted a video card that supported OpenCL.

I’d considered upgrading the video card awhile ago, but I just wasn’t too interested in spending $399 or so for something I didn’t use very much. 

A quick look for compatible cards found an ATI Radeon HD6870 which had Mac (EFI) support and the Mac Pro power cables (plus a mini-display port adapter, which I didn’t need since the card had two DVI ports and I only have two monitors on my Mac Pro — that may change now) for $169.00 (free shipping)… and since I had almost $100 in eBay vouchers/credits that were going to expire in a little over a week I was like “no problemo” — lol.

I ordered the card, and it arrived today — I won’t say it was easy to install (Macs, even Mac Pros aren’t really designed to be easy to upgrade), but it installed with no problem and it’s working just fine.

Is it faster?  Probably, but I won’t know if it really makes a big difference until I try and do a video encode (the GPUs on the card will be used in addition to the eight cores of CPU — though my bet is the 32GB of memory really makes the biggest difference in the encode speed).

While I had the Mac Pro opened up, I went ahead and replaced one of the 500GB hard drives with a 3TB hard drive I had around… since I tend to mostly use the Mac Pro for video project I figured having a local copy (at SATA speeds) would be handy.
